fix(search): down-weight the project name in ranking — completes #720 (#748)
The per-word path fix (#745) brought the backend to parity but not above: the project name still gave the lexically-matching stack a residual dir match + an FTS class-name match, so a backend query that included the project name still ranked the frontend at/above the backend. Derive the project name from go.mod module / package.json name / repo dir, and treat a query word matching it as non-discriminative: drop it from path relevance and from codegraph_explore's PascalCase type-disambiguation bias (reporter's suggestions #1/#2) — unless it's the only query word, so a bare project-name search still scores. Narrow by construction: the down-weighting fires ONLY when a query word matches the derived project name (≥5 chars), so every query that doesn't name the project is byte-identical. On the reporter's repro the backend controllers now top a backend question that includes the project name; queries without it, bare project-name queries, and normal symbol queries are unchanged. Query-time only (no re-index). Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

fix(search): score path relevance per query word, not per sub-token (#720) (#745)
A multi-word PascalCase query token — typically a project name a user includes (`SuperBizAgent backend routes`) — splits into sub-tokens (superbizagent / super / biz / agent) that ALL match the same path segment, so path relevance summed +5 four times for one concept. In a mixed-stack repo that ~doubled every score of the lexically-matching stack's file, burying the stack the query was about. Score path relevance per original query WORD instead: a word matches a path level if any of its sub-tokens do, and counts once — while still splitting the word (via extractSearchTerms on the original case) so it matches across naming conventions (`getUserName` → `get_user_name`). Distinct words each still contribute. Partial fix: this removes the dominant path over-counting (backend rises from absent-in-top-6 to parity on the reporter's repro). The residual lexical edge from the project name in the FTS class-name match + dir match is a deeper down-weighting change, tracked separately. No re-index needed (query-time).

fix(go): attribute calls inside top-level closures to the var, not the file (#693) (#744)
A function called only from an anonymous func_literal at package level — a
cobra `RunE: func(){…}` handler, a goroutine literal, a callback closure
stored in a `var` — had its call leak to the FILE node, because the Go
var-initializer walk ran with an empty scope. So `callers`/`impact` showed
the function with a file (or no meaningful) caller, unlike JS/TS where an
arrow-in-const becomes a named node whose calls attribute correctly.
Scope the Go top-level var/const initializer walk to the declared symbol, so
a call nested in any func_literal initializer (struct field, slice/map,
nested closure) attributes to the enclosing var. EXTRACTION_VERSION 3->4
(re-index to pick up the corrected attribution).
Validated on cli/cli (858 Go files): node/edge counts identical, file-level
dependents byte-identical (no regression), and 62 top-level-closure calls
correctly moved from file-attributed to var-attributed.

fix(scan): don't abort indexing on a non-UTF-8 or unparseable .gitignore (#682) (#743)
A .gitignore transparently encrypted in place by corporate DLP / endpoint software (UTF-16 header + ciphertext), or one containing a pattern the `ignore` library can't compile to a regex (`\[` -> "Unterminated character class"), crashed the entire sync/index. The throw is LAZY — it surfaces at match time (`ig.ignores()`), not `.add()` — so the existing add-time try/catch never caught it, and the error never named the offending file. Read .gitignore defensively: skip a file that isn't valid UTF-8 text whole (NUL byte or fatal UTF-8 decode), drop only the individual uncompilable patterns from a text one (probe-compile, then per-line fallback), and warn with the file path. Indexing continues either way. The watcher inherits the fix via buildDefaultIgnore. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

fix(extraction): map PHP include/require to file→file dependency edges (#660) (#663)
PHP's importTypes only captured namespace_use_declaration, so include/require(_once) — the dependency mechanism in procedural and script-style PHP — never produced edges. callers, impact, and trace missed the entire file-include graph; only namespace `use` became a dependency edge. Capture the four include/require expression types and emit file→file imports edges, reusing the path-based resolution that C/C++ #include already goes through. Only static string-literal paths are resolved (relative to the including file); dynamic forms (include $var, require __DIR__ . '/x', interpolated strings) are skipped. Include PATHS are distinguished from namespace `use` symbols by shape: a path contains '/' or '.', which PHP identifiers and FQNs never do. A path-shaped include that doesn't resolve to a known project file is left unresolved and does NOT fall back to the symbol name-matcher, which would otherwise mis-connect "inc/db.php" to an unrelated db.php elsewhere — a wrong edge is worse than a missing one.

fix(cpp): resolve calls through singletons/factories/chained getters (#645) (#742)
A C++ method call whose receiver is another call's result — `Foo::instance().bar()`, `WidgetFactory::create().draw()`, `openSession()->run()`, or the same stored in an `auto` local first — lost the receiver's type during extraction. The callee degraded to a bare method name, so when two classes shared a method name the call silently resolved to whichever was indexed first (or not at all), corrupting callers / impact / trace with a plausible-but-wrong edge. Three parts: - Capture C++ return types (new nodes.return_type column, schema v5): the function_definition's `type` field, normalized — smart-pointer pointee unwrapped, void/primitives dropped. - Preserve the inner-call receiver in extraction: a C/C++ field_expression whose receiver is itself a call is encoded `inner().method` instead of dropping to the bare name. Other languages keep the existing behavior. - New resolution strategy (matchCppCallChain): infer the receiver's class from the inner call's return type, then resolve AND validate the method on it. Handles singletons/accessors, factories returning a different type, free-function factories, make_unique/make_shared/new/direct construction, single-level member chains, and namespace-qualified inner calls. A wrong inference yields no edge, never a wrong one. EXTRACTION_VERSION 2->3 (re-index to populate return types). Validated on the issue repro + spdlog: node count stable (no explosion), deterministic, and ~100 pre-existing wrong `.size()`-style edges removed.

feat(directory): CODEGRAPH_DIR env var to override the index dir name (#636) (#741)
Two environments that share one working tree — most concretely Windows and WSL — can't safely share a single `.codegraph/`: the daemon lockfile records a platform-specific pid + socket (named pipe vs Unix socket), and SQLite locking across the WSL2/Windows filesystem boundary is unreliable, so two daemons over one index risks corruption. Add a `CODEGRAPH_DIR` env var (default `.codegraph`) that overrides the per-project data directory name, so each environment keeps its own index in the same tree (e.g. `CODEGRAPH_DIR=.codegraph-win` on Windows). The name is resolved live and validated (rejects separators / `..` / absolute, falling back to the default with a one-time stderr warning). Indexing and file-watching now skip ANY `.codegraph-*` sibling so neither side trips over the other's data. Routes the previously-hardcoded `.codegraph` literals (db path, lockfile, error log, watcher ignore, file-scan skip, installer) through the resolver. No extraction-version bump — index content is unchanged. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

feat(extraction): index string-literal names in generic tuple type aliases (#634) (#740)
TypeScript service/RPC contracts written as a tuple of generic types — `type List = [Service<'query_apply_record', Req, Resp>, …]` — carry their names only as string-literal type arguments, so static extraction never indexed them and `codegraph query query_apply_record` returned nothing. Add a narrow TS/TSX type-alias pass that emits each tuple entry's string-literal name as a `method` node under the alias (qualifiedName `List::query_apply_record`), making it searchable. Scope is limited to a direct literal arg of a generic that is a direct tuple element, with a valid-identifier filter — so utility types (Pick/Omit/Record), deeper nested generics, and route paths produce no noise. Bumps EXTRACTION_VERSION so existing indexes get a re-index hint. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

feat(mcp): codegraph_node reads files like the Read tool — offset/limit, byte-parity (#738)
Makes codegraph_node a drop-in faster Read for indexed source files (file-read mode: <n>\t<line> like Read, offset/limit, + blast-radius header; symbolsOnly for the map). Fixes the old file-view dropping imports/line-numbers. #383/#527 preserved. Validated by A/B: explore/node already return source + line numbers, so Read=0 when used. Includes the A/B eval harness scripts. Full suite green (1270). |

feat(mcp): steer agents to codegraph during implementation + file-view node mode (#733)
* feat(mcp): steer agents to codegraph during implementation, not just Q&A Two changes targeting agents that reach for Read during edits instead of codegraph: 1. Reframe the agent-facing steering (server-instructions + codegraph_node/explore descriptions): drop "consult BEFORE ... not during"; position codegraph_node as the Read upgrade for a named symbol (verbatim current on-disk source, safe to Edit from, + caller/callee trail), explore PRIMARY / node SECONDARY, with the "cached intelligence — better context, fewer tokens" framing. 2. File-view mode: codegraph_node now accepts a `file` with no `symbol` and returns that file's symbol map + graph role (its dependents), plus verbatim bodies with includeCode — so it can displace a path-keyed Read, not just a symbol lookup. Resolves a path or basename; dedups nested members; budget-capped. To be A/B'd on an implementation task before shipping (per the retrieval doctrine: steering changes must be measured, not assumed).

fix(mcp): silence the daemon-attach log by default (#618) (#725)
The "Attached to shared daemon" line is benign INFO, but it was written to stderr — and MCP hosts render all server stderr at error level (and append an `undefined` data field), so on every session start a healthy attach showed up as `[error] … undefined`. It is now gated behind CODEGRAPH_MCP_LOG_ATTACH=1: silent by default, opt-in for debugging daemon attach. Both attach sites (runProxy + connectWithHello) route through one helper. The daemon integration tests opt the harness into the log so their attach assertions still observe a successful attach. Re-applies the approach from #640 by @mturac.

fix(security): resolve symlinks in path validation to block out-of-root reads (#527) (#724)
* fix(security): resolve symlinks in path validation to block out-of-root reads (#527) validatePathWithinRoot was purely lexical (path.resolve + startsWith), so an in-repo symlink whose logical path is inside the project root but whose real target escapes it passed validation — and both content-serving read sinks (codegraph_node includeCode, codegraph_explore source) then readFileSync'd it, leaking out-of-root file contents (e.g. ~/.ssh, /etc) to the agent. Add a realpath layer: after the lexical check, resolve symlinks on both the candidate path and the root and re-compare, rejecting anything whose real path escapes the root. An in-root symlink is still allowed (no over-blocking). Comparison is case-insensitive on Windows (NTFS + realpath casing). Not-yet- existing paths (ENOENT) fall back to the lexical result so about-to-be-written files still validate; other resolution errors reject. Removes the dead, never-called isPathWithinRoot / isPathWithinRootReal helpers (the latter a footgun — it returned true on realpath failure). Adds RED->GREEN tests: in->out file/dir symlinks rejected, in->in allowed, ../ rejected, ENOENT allowed, plus an end-to-end test proving getCode no longer serves an out-of-root file reached through a dir symlink.

fix(security): index config files by key only, never surface values (#383) (#722)
Spring `application.{properties,yml}` keys (and Shopify Liquid `{% schema %}`
blocks) were storing the config VALUE in the node docstring, and
`codegraph_explore`'s source section re-read the raw `key = value` line off
disk — so a secret committed to a config file (DB password, API key, JDBC URL
with embedded credentials) could be pushed into an agent's context via
explore/node output without the agent ever opening the file.
Config-leaf nodes (`kind: 'constant'` in a config language) now surface the KEY
only, via a shared `isConfigLeafNode` predicate applied at both surfacing
paths: the value is dropped from extraction, `getCode`/`includeCode` returns
the key instead of the file line, and explore excludes config leaves from
source rendering. The predicate can't match real code (real constants are
ts/java/go/…), so `@Value`/`@ConfigurationProperties` resolution and impact are
unaffected. Adds a regression test asserting a planted secret never appears in
`codegraph_explore` / `codegraph_node` output while the keys still resolve.

fix(daemon): keep a session alive when its daemon is restarted under it (#662) (#713)
When an MCP host (opencode and others) SIGTERM's the shared daemon as a new session starts, the existing session's proxy used to exit on the dropped socket — silently losing CodeGraph for that session, and hanging any request in flight at the drop. The SIGTERM originates in the host's process-tree teardown, not in CodeGraph (nothing here signals another process), so the fix is proxy resilience, not chasing the signal. The local-handshake proxy now treats a daemon disconnect as recoverable rather than terminal: it falls back to its in-process engine for the rest of the session (the same path used when no daemon is reachable at startup, and what CODEGRAPH_NO_DAEMON does) and re-serves any requests that were in flight to the dead daemon, so the host never hangs. The proxy still exits when the HOST goes away (stdin close / PPID watchdog) — only daemon loss is now non-fatal. Also replaces the over-the-wire liveness-sweep test added in #712 — which was flaky under heavy parallel load (a raced raw-socket connect) — with a deterministic Daemon.reapDeadClients unit test. The client-hello round-trip is still exercised by every daemon test (the real proxy now sends it). Validated with a reproduction (proxy stays alive, in-flight request answered, post-drop request recovers) and a regression test in mcp-daemon.test.ts. Confirmed on macOS (full suite green) and a Windows 11 VM. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

fix(daemon): reap dead-peer clients + inactivity backstop so a daemon can't leak (#692) (#712)
Layer-2 defense-in-depth follow-up to the Windows PPID watchdog fix (#711). That fix makes an orphaned proxy exit so its socket closes and the daemon reaps via the refcount + idle timer. This adds two daemon-side safety nets for the residual case where a socket close is never delivered (a Windows named-pipe hazard) and a phantom client would otherwise pin the daemon forever: - Liveness sweep: a proxy now sends an optional client-hello carrying its pid (+ host pid) right after verifying the daemon hello; the daemon periodically drops any client whose peer process is dead, re-arming the idle timer. Fail-safe and version-pinned — a connection that never sends the hello just falls back to the socket-close lifecycle, and the daemon reads it before the transport so a non-hello first line is handed through untouched. - Inactivity backstop: the daemon exits after a generous no-traffic window (CODEGRAPH_DAEMON_MAX_IDLE_MS, default 30 min) even with clients attached, so a phantom client that sends nothing can't keep it alive. Pure helpers (parseClientHelloLine, peerIsDead) are unit-tested; the full handshake + sweep and the backstop are covered end-to-end in mcp-daemon.test.ts. Validated on a real Windows 11 VM: the sweep reaps a dead-pid client over a named pipe and the backstop fires with a client still connected.

fix(windows): reap orphaned MCP processes when their parent exits (#692, #576, #680) (#711)
On Windows the PPID watchdog could never fire: orphans aren't reparented, so `process.ppid` stays constant after the parent dies (defeating the ppid-change check), and the standalone bundle pre-bakes `--liftoff-only`, skipping the relaunch that sets `CODEGRAPH_HOST_PPID` (defeating the host-liveness check). With neither signal available, an orphaned proxy / direct server ran forever, the shared daemon never saw the client disconnect, and its idle timer never armed — node processes accumulated until CPU saturated. Add a win32-only signal: poll the original parent's liveness directly, since ppid is stable there. Gated to Windows so POSIX double-fork cases keep relying on the ppid-change signal (a dead original parent is not proof of orphaning on POSIX). The decision is extracted into a pure, unit-tested helper shared by all three watchdog sites (proxy socket, proxy local-handshake, direct mode). Validated on a real Windows 11 VM: in the exact bundle scenario (direct mode, no HOST_PPID) an orphaned server now exits within one watchdog poll via the new path; the POSIX reparent path is unchanged and its integration test still passes.

feat(cli): add codegraph upgrade self-update + stale-index re-index hint (#710)
`codegraph upgrade [version]` detects how the CLI was installed — the standalone install.sh/install.ps1 bundle, npm-global, npx, or a source checkout — and updates in place: re-running the canonical install.sh on macOS/Linux, an in-place rename-and-extract swap on Windows (a running node.exe can't be deleted, only renamed, so the detached-helper approach is avoided), and npm/npx/source-specific guidance otherwise. Flags: `--check` (report only), `--force`, and a positional version to pin. Each full index is now stamped with the engine's EXTRACTION_VERSION in project_metadata; `codegraph status` (and `--json`) flags an index built by an older engine and recommends re-indexing, and `upgrade` prints the same reminder. Gated on EXTRACTION_VERSION so it never nags on extraction-neutral releases. Validated end-to-end on macOS (real bundle upgrade), Linux (Docker, real curl|sh) and Windows (Parallels VM, real in-place swap). 32 new unit tests.

fix(extraction): index Vue <template> component usages (#629 follow-up) (#659)
Vue's extractor parsed only the <script> block, so a component used solely in another component's <template> (`<MyButton />`) produced no reference — and thus showed a false 0 callers, even after the barrel-resolution fix in PR #657. This is the Vue analogue of Svelte's extractTemplateComponents. extractTemplateComponents() now scans the template (everything outside the <script>/<style> blocks, which also handles nested <template> tags for v-if/slots) for component tags: - PascalCase tags (`<MyButton/>`) — captured as-is. - kebab-case tags (`<my-button/>`) — converted to PascalCase so they match the imported component's name. Safe: an unmatched name creates no edge during resolution, so native custom elements just don't resolve. - Native HTML elements (lowercase, no hyphen) and Vue built-ins (Transition, KeepAlive, …) are skipped. Adds no nodes — only `references` — so node counts stay stable. With this plus #657, a Vue component re-exported through a barrel and used only in a template now resolves end-to-end (callers/impact/callees).

fix(resolution): resolve Svelte/Vue component barrels & workspace imports (#629) (#657)
Component barrels (`export { default as X } from './X.svelte'`) and
monorepo workspace imports (`@scope/ui/widgets`) left the consumer↔component
edge uncreated, so live components showed a false `0 callers` — the canonical
dead-code signal — risking deletion of live code.
The Svelte default-barrel case broke at FOUR layers, each of which alone left
it unresolved:
- findExportedSymbol matched only function/class for a default export, never
`component` (Svelte/Vue SFCs are kind 'component').
- extractImportMappings had no svelte/vue branch, so SFC consumers produced
zero import mappings and resolveViaImport never ran.
- EXTENSION_RESOLUTION had no svelte/vue entry, so relative imports from an
SFC (`./lib` -> `/index.ts`) resolved to nothing.
- getReExports parsed the barrel in the CONSUMER's threaded language, so a
.svelte consumer made extractReExports bail on a .ts index barrel.
Workspace package-subpath barrels get a new workspace-packages module
(mirrors go-module/path-aliases): reads package.json `workspaces`
(npm/yarn/bun) + pnpm-workspace.yaml, maps member name->dir, resolves
`@scope/ui/widgets` -> `packages/ui/widgets`. Gated behind the workspaces
field so single-package repos are unaffected.
Bare `./`/`.` directory imports already resolved; covered with a regression
test. Verified both directions (callers/impact AND callees) for Svelte; Vue
script-level imports also resolve. 4 new tests; full suite green (1126).

fix(resolution): stream node-kind scans in synthesis to fix OOM on dense files (#610) (#653)
The callback/observer synthesizers loaded every function and method node into
memory at once (getNodesByKind('function'/'method')) before scanning them down
to a tiny matched subset. On a symbol-dense project that array is gigabytes, so
indexing spiked the JS heap and aborted with "JavaScript heap out of memory".
Add QueryBuilder.iterateNodesByKind (a lazy node:sqlite cursor) and stream the
synthesizer scans instead of materializing them. Parsing and reference
resolution were already bounded; only the synthesis enumeration wasn't.
Measured on 80 files x 14k functions (~1.1M nodes): peak RSS 3717 MB -> 1318 MB,
no OOM. Full suite green; synthesized edges unchanged.

fix(watcher): bound fd/watch cost with a native fs.watch hybrid (#644, #496, #555, #628, #579) (#650)
chokidar v4 holds one OS file descriptor per watched file on macOS (libuv's kqueue backend registers an fd per vnode; fsevents is installed but v4 no longer uses it). On a large project the `serve --mcp` daemon accumulated tens of thousands of open REG descriptors and exhausted kern.maxfiles — crashing unrelated processes system-wide with ENFILE. #276 only trimmed the count by ignoring directories; the source tree still cost one fd per file. Replace chokidar with a pure-JS native fs.watch hybrid, keeping codegraph's zero-native-addon "any OS builds any bundle" invariant: - macOS / Windows: a single recursive fs.watch (one FSEvents stream / ReadDirectoryChangesW handle) -> O(1) descriptors regardless of repo size. - Linux: one inotify watch per directory (O(dirs), dynamic add for new dirs, capped via CODEGRAPH_MAX_DIR_WATCHES) instead of per-file watches. Validated empirically: macOS 0 extra fds at 6k and 12k files; Linux 31 inotify watches at 6k files (per-file would be 6k); Windows recursive catches nested and new-directory edits. Full test suite green. Tests drive the watcher through an inertForTests seam (no OS watcher) for determinism under parallel vitest, with one real-fs end-to-end test exercising the genuine native path.

feat(mcp): codegraph_explore as the sole primary tool + store coverage + overload disambiguation (#647)
## Summary
Completes the explore-overhaul arc: `codegraph_explore` becomes the single primary tool an agent reaches for, and its coverage + output shape are tuned so flow/architecture questions resolve with near-zero Read/Grep.
### What changed
- **explore is the sole primary tool** — removed `codegraph_context` (the fuzzy-input Read-trigger) and `codegraph_trace` (under-picked by agents); explore already surfaces the call flow among the symbols you name. A plain natural-language question now works as the query.
- **Store/handler coverage** — functions defined inside object literals (Zustand `create((set, get) => ({ … }))`, Redux/Pinia/MobX, exported handler/route maps) are indexed as real symbols, including calls through `useStore.getState().fn()` and destructured `const { fn } = useStore.getState()`. A general AST rule, not a per-lib hack.
- **Overload disambiguation** — explore leads with the *right* definition when a method name is overloaded across types (a PascalCase type token in the query biases to that type's own def); `codegraph_node` returns *every* overload's body in one call, with an optional `file`/`line` selector to pin one.
- **Method-atomic render** — explore never returns half a method; at the size budget it drops whole methods/files (and lists what it dropped) instead of truncating a body mid-method.
- **Native-read-shaped output** — per-call output is capped to ~24K with a 25K hard ceiling and concentrated into ~150–250-line flow windows, mirroring how the agent natively reads; repo size scales the *call* budget, not the per-call size (a larger response just gets externalized to a file the host Reads back).
- **Blast radius** folded into explore (dependents + covering tests, locations only).
### Benchmark (refreshed on this build)
Re-validated the 7-repo A/B on 2026-06-02 (Opus 4.8, effort=high, median of 4). WITH arm re-measured on this build, WITHOUT reused:
**~16% cheaper · 47% fewer tokens · 22% faster · 58% fewer tool calls** — 0 file reads on 6 of 7 repos (Gin ~1).
The arc trades larger, cache-heavy explore responses for guaranteed near-zero reads, so cost/token margins soften vs the prior build (Excalidraw and Tokio land at cost break-even) while time and tool-calls stay clear wins everywhere — consistent with the project's stated optimization target (latency + tool-calls, not token cost).
### Validation
- Full suite green: **1112 passed, 2 skipped**.
- 28/28 plain WITH runs across the 7 README repos completed clean; reads median 0 on 6/7.

feat(npm): restore programmatic/embedded SDK API (#354) (#603)
The 0.9.x thin-installer turned @colbymchenry/codegraph into a bin-only
shim: require("@colbymchenry/codegraph") threw MODULE_NOT_FOUND and no
types shipped, breaking embedded library consumers (e.g. Electron apps)
upgrading from 0.8.0.
Restore programmatic use without re-bloating the thin shim or duplicating
the ~49 MB of grammars the per-platform bundle already carries:
- main -> npm-sdk.js re-exports the installed per-platform bundle's compiled
library (lib/dist/index.js) at runtime, reusing that bundle's own deps; it
falls back to a self-healed cache bundle, else throws an actionable error.
- types -> ship the .d.ts tree only (~590 KB) in the main package, built from
the same release so it can never skew from the runtime it re-exports.
- exports map resolves the `types` condition (nodenext) and the default entry.
- DatabaseConnection + QueryBuilder are now top-level exports, so embedded
callers get the building blocks from the package entry instead of deep
dist/ imports (which the shim no longer ships).
The CLI/MCP `bin` keeps execing the bundled Node; only library consumers run
on their own runtime, which must be Node 22.5+ for the built-in node:sqlite.
Validated end-to-end: built a real darwin-arm64 bundle, packed the npm
packages, installed them into a throwaway consumer, and confirmed require()
plus a full init/indexAll/searchNodes round-trip and the low-level
DatabaseConnection/QueryBuilder path all work on the host Node; types resolve
under both nodenext and classic node resolution; and the CLI shim still
launches. New hermetic tests cover npm-sdk resolution, cache fallback, and the
missing-bundle error.

feat(mcp): per-symbol adaptive codegraph_explore sizing (#569)
Sizes codegraph_explore to the answer, not the file count: shows the mechanism + the exact methods you named in full (even buried in a large file) while collapsing redundant interchangeable implementations to signatures. Adds uniqueness-aware spare, per-symbol focused rendering of family files, all-tier test-file exclusion, and named-method cluster survival in non-sibling god-files. Validated A/B (Opus 4.8, 7-repo sweep): avg 25%% cheaper / 57%% fewer tokens / 23%% faster / 62%% fewer tool calls.

feat(mcp): adaptive codegraph_explore sizing — skeletonize redundant polymorphic siblings (#564)
codegraph_explore now skeletonizes off-spine, redundant members of a polymorphic family (OkHttp's interceptor chain, Django's SQLCompiler family) to signatures instead of shipping every full body, while keeping the dispatch mechanism, the orchestrator/base, and any method the agent named in full. Sizes the response to the answer rather than the budget cap, so interface-heavy flows stop costing more than plain grep/read. Default on; CODEGRAPH_ADAPTIVE_EXPLORE=0 disables. Gate: off-spine + >=3-impl sibling + not-spared, where spared = the agent named a callable in the file UNLESS the file defines the family's supertype (a huge base+subclasses file is Read-anyway, so skeletonizing frees explore budget). Validated headless A/B (Opus 4.8): both former README cost outliers flipped — OkHttp and Django went from costlier-than-native to cheaper; full 7-repo average 22%% cheaper / 47%% fewer tokens / 20%% faster / 50%% fewer tool calls, every repo cost-positive, inert repos unchanged. 7-case regression test.

feat(resolution): gin middleware-chain synthesizer + Opus 4.8 benchmark refresh (#547)
* fix(agent-eval): detect idle by content-stability, not spinner absence Opus 4.8's extended-thinking TUI shows no spinner / interrupt hint / timer while it streams its final answer — those appear only during the thinking and tool-use phases. The old detector treated ~5s of not-busy + prompt-present as done, so it killed interactive runs mid-answer, silently truncating both arms of the tmux A/B (low tool counts; the final assistant message left as a mid-investigation preamble). Now a run is done only when the captured pane stops changing for ~8s; while streaming, the pane changes every poll so stability never accrues. BUSY_RE stays as the immediate busy-reset for the thinking/tool/live-timer phase. Content-stability is model-agnostic — it survives future spinner re-wordings. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(readme): refresh VS Code benchmark on v0.9.7 + Opus 4.8 Re-ran the VS Code A/B (headless median-of-4) on the current build and model. Cost savings held at 26% ($0.66->$0.89), but token/time/tool-call savings narrowed (78->63%, 52->20%, 85->69%) because Opus 4.8's without-CodeGraph arm explores far more efficiently than 4.7's did (16 tool calls vs 55, no Explore-subagent fan-out); the WITH arm is unchanged at 5 calls / 0 reads. Recomputed the average row and noted that the VS Code row is now a different model/version epoch than the other six. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(resolution): synthesize gin middleware-chain edges (Next -> registered handlers) Gin runs its entire handler chain through one dynamic line in (*Context).Next -- c.handlers[c.index](c), a slice-index dispatch tree-sitter can't resolve. So callees(Next) dead-ended at the len() helper and the flow ServeHTTP -> handleHTTPRequest -> Next stopped at the exact symbol a 'how does the middleware chain work' question is about, sending the agent to re-query and Read/grep (a measured gin WITH-arm rabbit-hole: 2/4 headless runs spiraled to ~5min, one mis-firing the opt-in Workflow orchestration tool). Find the chain dispatcher (a Go method invoking a handlers slice by index) and link it -> every HandlerFunc registered via .Use/.GET/.../.Handle, so callees(Next) and trace(ServeHTTP, handler) connect end-to-end. Gated on the dispatcher existing (inert on non-gin Go repos), named handlers only (inline closures skipped), capped; provenance heuristic / synthesizedBy gin-middleware-chain, registeredAt = the registration site. Validated: gin callees(Next) now surfaces Logger/Recovery/ErrorLogger + handlers (node count stable at 2,544; 5 precise edges); agent A/B (headless median-of-4, Opus 4.8) flipped gin from -58% cost / -129% time to +7% cost / +35% tokens / +8% time / 38% tool calls, all 4 WITH runs clean (0 Read/Grep/Bash). 167/167 unit tests pass incl. the new gin-middleware-chain test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(readme): publish uniform Opus 4.8 benchmark + per-repo breakdown accordion Refresh all 7 benchmark rows to the v0.9.7 / Opus 4.8 headless median-of-4 (was a mix of the 4.8 VS Code row + six 4.7 rows). New average 18% cheaper / 51% fewer tokens / 16% faster / 57% fewer tool calls; headline + methodology note updated 4.7->4.8. The gap is smaller than the prior 4.7 numbers because Opus 4.8's native grep/read is more efficient (the without-arm no longer fans out into large Explore-subagent sweeps) -- not a codegraph regression; CodeGraph still cuts tool calls and tokens on all 7 repos, with cost marginal/negative only on django + okhttp. Adds a top-level 'Per-repo breakdown' accordion (per-metric Time/Reads/Grep-Bash/Tool calls/Tokens/Cost, WITH vs WITHOUT, per repo) directly below the condensed summary; methodology/queries/why-wins move to a second accordion.

fix(extraction): count all file-level-tracked langs (incl .properties) as indexed (#544)
Completes #357. The no-symbol file-level class is yaml/twig/properties, but the count fix only covered yaml/twig — so a .properties-only project still printed "No files found to index" even though the files were stored. Introduce a single isFileLevelOnlyLanguage predicate (the canonical set behind the tree-sitter no-symbol branch, xml excluded since its MyBatis extractor emits a file node) and use it at both count sites and the extraction dispatch so the list can't drift. Adds .properties regression coverage for indexAll() and indexFiles(). Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

fix(installer): stop duplicating agent instructions; MCP server is the single source of truth (#529) (#538)
The installer wrote a `## CodeGraph` usage block into each agent's
instructions file (CLAUDE.md / AGENTS.md / GEMINI.md / .cursor/rules /
Kiro steering) that duplicated, almost verbatim, the guidance the MCP
server already emits in its `initialize` response — so agents that
surface MCP instructions (Claude Code) read the same playbook twice
every turn.
All 6 instruction-writing targets (claude, cursor, codex, opencode,
gemini, kiro) now stop writing the block. install self-heals by
stripping a block a previous version wrote (uninstall already did), so
the next `codegraph install`/`uninstall` cleans up existing installs;
upgrading the package alone does not (the leftover block is harmless).
server-instructions.ts is now the single source of truth — the two
steers unique to the old template ("trust codegraph, don't re-verify
with grep" and the not-initialized -> `init -i` hint) are ported there.
Removes the now-dead INSTRUCTIONS_TEMPLATE / CLAUDE_MD_TEMPLATE,
claude-md-template.ts, writeClaudeMd / hasClaudeMdSection, and the
Cursor-only wireProjectSurfaces bootstrap. The install log learned a
"Removed" verb. Tests rewritten to the new contract + self-heal
coverage (140/140 installer tests pass).

fix(windows): suppress console popup on child_process calls (#498)
On Windows, v0.9.5's detached shared daemon (#411) has no inherited console, so any console-subsystem child it spawns gets a fresh visible console window unless the spawn passes `windowsHide: true`. The fix adds the flag to all ten `spawnSync` / `execFileSync` / `execSync` call sites across extraction, sync, installer, and the WASM-flags relaunch. macOS/Linux ignore the option, so this is a no-op elsewhere. Fixes #485, #510, #530. Co-authored work: - #498 (csw-chen) — full sweep across extraction, sync, installer, and wasm-runtime. **This is the change being merged.** - #505 (yushengruohui) — independently identified and fixed the 7 git execFileSync sites. Superseded by #498's broader sweep; same diagnosis. - #521 (JirA44) — independently identified and fixed the WASM-runtime spawnSync re-exec. Superseded by #498's broader sweep; same diagnosis. Validated on Windows 11 ARM64 (Parallels): a detached parent's 15 git spawns produce 15 visible black flash-windows without the fix and 0 with it. |

feat(mcp): multi-module Go trace-quality + small-repo retrieval tuning (#494)
* feat(go): generated-file down-rank + gRPC stub-impl bridge + trace-failure inlining
Multi-pronged fix to make codegraph competitive on Go multi-module repos
(cosmos-sdk, etcd) where it previously lost or tied. Driven by an 8-question
agent-eval audit across cobra, gin, prometheus, cosmos-sdk, and etcd: the
baseline had codegraph losing ~60% on cost on cosmos-sdk and mixed on etcd
deep cross-module flows, while winning cleanly on the single-module and
non-protobuf-heavy repos.
Diagnostics ruled OUT `go.work` parsing as the gap (prometheus crushes
without it). The actual failure modes were generated-file noise warping
disambiguation, missing gRPC interface→impl bridge in structural-typing Go,
and trace's failure path triggering 3-5 follow-up tool calls instead of
inlining the material the agent needed.
Changes:
- New `src/extraction/generated-detection.ts` — path-pattern classifier
for `.pb.go`, `.pulsar.go`, `_grpc.pb.go`, `_mock.go`, `_mocks.go`,
`mock_*.go`, `.generated.[jt]sx?`, `_pb2(_grpc)?.py`, `.pb.{cc,h}`,
`.g.dart`, `.freezed.dart`. Applied as a stable sort tiebreaker in
`findSymbol`, `findAllSymbols`, `codegraph_search` (MCP + CLI),
`codegraph_explore` file ranking, and context formatter Entry Points /
Related Symbols / Code blocks. Cosmos's `msgServer.Send` now ranks #3
instead of #9 on a `Send` search.
- New `goGrpcStubImplEdges` synthesizer in `callback-synthesizer.ts` —
detects `UnimplementedXxxServer` structs in generated files, identifies
their RPC methods (excluding `mustEmbed*` / `testEmbeddedByValue` gRPC
markers), and emits `calls` edges to the matching methods on any
non-generated struct whose method-name set is a superset. Closes Go's
structural-typing gap that the existing `interfaceOverrideEdges` (Java /
Kotlin only) couldn't bridge. 467 bridge edges on cosmos-sdk; bank's
`UnimplementedMsgServer::Send` points to `x/bank/keeper/msg_server.go`
only, not to `msgClient` siblings or mock files.
- Trace-failure rewrite (`handleTrace`) — when no static path connects
endpoints, instead of telling the agent to call `codegraph_node` (a
3-4-call fan-out), inline both endpoints' bodies (120 lines / 3600 chars
per endpoint), their callers (≤6), and callees (≤8) in one response.
- Trace endpoint-pairing improvements — scores every `from`×`to`
candidate combo by shared directory prefix and tries the best-paired
pair first (the full candidate set, not just FTS top-5). A
less-canonical-path penalty (`enterprise/`, `contrib/`, `examples/`,
`vendor/`, `third_party/`, `deprecated/`, `legacy/`) ensures the
canonical-module pair wins even when a side-experiment shares more of
its directory prefix. Find-path probe budget capped at 20 pairs.
- Test-file deprioritization in `codegraph_explore` `isLowValue` — adds
suffix patterns (`_test.go`, `_spec.rb`, `.test.ts`, `.spec.tsx`,
`Test.java`, `Spec.kt`) alongside the existing directory-style patterns.
Otherwise etcd's `watchable_store_test.go` consumes 5K chars of explore
budget that should go to the hand-written flow source.
Tests:
- New `__tests__/generated-detection.test.ts` (4 unit tests) pins the
suffix patterns.
- New "Go gRPC stub→impl synthesis" integration test suite in
`frameworks-integration.test.ts` (2 tests): positive bridge from stub
to hand-written impl, AND the precision case (don't bridge to a
generated sibling like `msgClient` in the same .pb.go).
- Full suite: 1076/1076 pass.
Empirical (post-fix, n=2 average per question):
| Repo / Q | WITH | WITHOUT | Reads (W/WO) | Time (W/WO)
|-------------------------|------------|-------------|--------------|------------
| cobra (parse cmds) | $0.27 | $0.27 | 0 / 4 | 39s / 60s
| prometheus (scrape→TSDB)| $0.63 | $0.70 | 0 / 6 | 106s/143s
| cosmos-sdk Q1 (MsgSend) | $0.41 | $0.26 | 1 / 2 | 67s / 64s
| cosmos-sdk Q2 (Delegate)| $0.47 | $0.46 | 0 / 5 | 50s / 73s
| cosmos-sdk Q3 (gov tally)| $0.34 | $0.31 | 1.5 / 3 | 54s / 76s
| etcd Q1 (Put→raft) | $0.65 | $0.78 | 0 / 4 | 98s / 129s
| etcd Q2 (watch) | $0.36 | $0.50 | 0 / 4+ | 58s / 89s
Codegraph wins on reads + time on every question. Cost is mixed: 3 clean
wins, 3 tied (within 10%), 1 stubborn cost loss on the grep-favored Q1.
Compared to baseline, the cosmos-sdk cost-gap collapsed from -60% to -15%
on average, and Q3 went from a 75% loss to a tie. Raw run artifacts in
`/tmp/cg-finalv2-*/` and `/tmp/cg-final-*/`.
Memory written at `project_go_multi_module_audit.md` for the methodology

* feat(mcp): auto-inline trace in codegraph_context for flow queries
When a codegraph_context task contains a flow keyword ("trace", "from",
"reach", "flow", "propagat", "how does", "how do") AND at least two
distinct PascalCase / camelCase identifiers, internally invoke trace
between the first two extracted symbols and splice the trace body into
the context response. Conservative trigger by design: false positives
waste one graph query; false negatives just fall back to the agent
calling trace itself (existing path-proximity wiring handles either
case).
Goal: collapse the agent's typical context → trace → explore sequence
into a single context call for clear flow queries, closing the
remaining cost-overhead gap on multi-call patterns. The path-proximity
+ less-canonical-path scoring + the trace-failure-inlined-bodies
behavior already let the inline trace land on the right endpoint pair
and return enough material that no follow-up codegraph_node/Read is
needed.
Doesn't fire on:
- cobra's "How does cobra parse commands and flags?" (no PascalCase
symbols) — verified in regression run, no behavior change ($0.260
WITH vs $0.257 WITHOUT, basically tied)
- queries where the agent doesn't call codegraph_context at all
(cosmos Q1 in the audit went search → trace → node → trace → node)
Tests: 1076/1076 still pass.

* feat(mcp): trace failure inlines TO file siblings to displace node fan-out
The cosmos-Q1 audit revealed a static-resolution gap: msgServer.Send's
*real* next hop is `k.Keeper.SendCoins` — an interface-method call on an
embedded field that tree-sitter can't resolve. The static getCallees list
for msgServer.Send is all utility/error functions (StringToBytes, Wrapf,
…). The actual flow (SendCoins → subUnlockedCoins → addCoins →
setBalance) lives entirely inside `x/bank/keeper/send.go`, which is also
where the TO endpoint (setBalance) lives.
When trace fails (no static path), inline the **top 5 functions/methods
in the destination file**, ordered by line-distance from the TO node.
This catches the flow that interface-method calls obscure — the
canonical "k.<Iface>.<Method>" pattern in Go, also relevant to Java
dependency-injection / Rails service-object dispatch / etc. where
interface dispatch hides the real call.
Conservative: only fires on trace FAILURE (no static path); the success
path is unchanged. Per-body cap (40 lines / 1200 chars), top 5 siblings.
Bookkeeps with `inlinedBodies` Set so endpoints already shown above
aren't duplicated.
Result: cosmos-Q1 — historically the most stubborn cost loss (-2.2× to
-39% across the audit) — flipped to a clean WIN: $0.257 WITH vs $0.449
WITHOUT (-43%), 34s vs 79s, 0 Reads vs 2 Reads + 5 Greps, 5 codegraph
calls vs 12. Regression-checked: prometheus, cobra, cosmos-Q2, etcd-Q1
all still WIN; Q3 is high-variance ($0.30-$0.45 range historically) and
fell within that on this run.

* feat: extend coverage to all supported languages, not just Go
PR review feedback: the audit was Go-driven, so the patterns I added
were Go-flavored. Extend each axis to every language CodeGraph
supports per the README, so the same improvements help Java / C# /
Python / TS / Swift / Dart projects too.
**generated-detection.ts** — Added patterns for:
- TS/JS: `.gen.[jt]sx?`, `.pb.[jt]s`, `_pb.[jt]s`, `_grpc_pb.[jt]s`
(ts-proto, gRPC-web, Apollo / GraphQL codegen, Hasura).
- Python: `_pb2.pyi` (mypy stubs from protobuf).
- C#: `.g.cs` (T4 / Razor codegen), `Grpc.cs` (protoc-gen-csharp).
- Java: `OuterClass.java` (protoc-gen-java), `Grpc.java`
(protoc-gen-grpc-java; this is where the `*ImplBase` abstract
class lives — same shape as the Go `Unimplemented*Server` stub).
- Swift: `.pb.swift` (protoc-gen-swift).
- Dart: `.pb.dart`, `.pbgrpc.dart`, `.chopper.dart`.
- Rust: `.generated.rs`.
**test-file deprioritization** (`isLowValue` in `codegraph_explore`)
— Added per-language conventions that the previous regex missed:
- Python: `test_*.py` (pytest discovery) and `*_test.py`.
- Ruby: `*_test.rb` (minitest) — `*_spec.rb` already covered.
- C#: `*Tests.cs`, `*Test.cs`, `*Spec.cs`.
- Swift: `*Tests.swift` (XCTest).
- Dart: `*_test.dart`.
**IFACE_OVERRIDE_LANGS** in `callback-synthesizer.ts`'s
`interfaceOverrideEdges` — extended from `java, kotlin` to
`java, kotlin, csharp, typescript, javascript, swift, scala`. Same
shape across these (nominal `implements`/`extends` on a class to an
interface/abstract base). Also iterates `struct` (Swift value types
conforming to a protocol) in addition to `class`. The existing
matchesSymbol-style logic and `getOutgoingEdges(..., ['implements',
'extends'])` work unchanged.
**CLAUDE.md** — Added a House rule: when the user references issues
or comments, anchor them to a date and version (last release vs.
last main commit vs. current branch tip) BEFORE concluding a fix is
incomplete. Issue #388 comments from May 25-27 were responding to
the released v0.9.5 / merged-PR-469 state — not to this branch's
in-flight work. The new rule walks through the disambiguation:
`grep -m1 '^## \[' CHANGELOG.md` for release version, `git log
--first-parent main -1` for main tip.
Tests: 1076/1076 still pass.

codegraph_explore / codegraph_trace / etc. wasn't moving the agent
toward better tool choices on top of the actual usage, but it was
adding ~525 tokens of cache-creation overhead to every question.
The trimmed descriptions keep the operational hints (e.g. "Query is
a bag of symbol/file names, not a question" for explore) but drop
the redundant prose.
2. **Dynamic tiny-repo tool gating** in `ToolHandler.getTools()`. On a
project with < 150 indexed files, the MCP server only exposes the
5 core tools (search, context, node, explore, trace) instead of all
10 — the omitted callers/callees/impact/status/files tools' use
cases on a sub-150-file repo reduce to one grep anyway. The MCP
tool-defs overhead is the #1 source of cost loss on tiny repos
(~$0.10-0.15 fixed cache-creation per question); cutting 5 tools
drops that by ~50%.
Effect on ky (~25 files, the worst pre-fix offender):
- Before: $0.59 WITH vs $0.42 WITHOUT (+42% loss, n=1)
- After: $0.32 WITH vs $0.44 WITHOUT (-26%, **flipped to WIN**)
Effect on cobra/sinatra/slim (50-80 files): still cost-loss, but
the gating doesn't regress them — same call-count, same reads.
The structural lower bound on those repos is what the agent's
grep+read path costs in absolute terms (~$0.20-0.30).
Non-breaking for medium+/large repos: all 10 tools remain exposed
when fileCount >= 150.
Tests: 1076/1076 still pass.

* feat(mcp): combined tiny-tier — smaller explore + tool gating (cobra/ky flip to WIN)
Combines the tool gating from the previous commit with a matching
explore-budget cut for projects under 150 files. The two together close
the cost gap that neither closes alone:
- Tool gating alone helped ky (WIN) but didn't move cobra/slim/sinatra
- Explore-budget cut alone helped slim slightly but regressed cobra
- COMBINED: cobra flips to WIN, ky stays a WIN, ky/cobra both clean
`getExploreOutputBudget(fileCount < 150)` returns:
maxOutputChars: 13000 (was 18000)
defaultMaxFiles: 4 (was 5)
gapThreshold: 7 (was 8)
maxSymbolsInFileHeader: 5 (was 6)
maxEdgesPerRelationshipKind: 4 (was 6)
includeRelationships: true (kept ON — cheap structural signal)
maxCharsPerFile: 3800 (unchanged — monotonic invariant w/ next tier)
This survives the cobra-regression-with-trim that the earlier
budget-only attempt suffered: with only 5 tools to choose from, the
agent doesn't fall back to extra codegraph_node calls when explore
returns less — there's no node call available.
Results on the four worst small-repo losses (combined intervention):
| Repo | Files | WITH (combo)| WITHOUT | Verdict (pre → post) |
|--------|-------|-------------|-------------|--------------------------|
| cobra | ~50 | $0.25 | $0.31 | loss → **WIN** (-19%) |
| ky | ~25 | $0.39 | $0.39 | -42% → tied |
| slim | ~80 | $0.31 | $0.24 | LOSS 31% → still LOSS |
| sinatra| ~60 | $0.30 | $0.23 | LOSS 18% → still LOSS |
sinatra/slim remain a cost-loss because their WITHOUT path is
structurally cheap (~$0.20 — fewer than 4 cheap grep+read calls).
Codegraph can't beat that absolute floor with any meaningful response.
Both still WIN on time + reads + tool-call count.
Tests: tier boundary cases updated to cover the new <150 / 150-499 /
500-4999 / 5000-14999 / >=15000 progression. Off-by-one guard updated
to include the new 149↔150 boundary. All 1076 tests pass.

* feat(context): trim maxNodes default to 8 on tiny repos
On a <150-file project the entire repo is grep-able in one turn, so the
20-node default `codegraph_context` was paying for a graph subset that
exceeds the agent's actual question. Cutting the tiny-repo default to 8
(typical 1-3 entry points + their immediate 1-hop neighbors) reduces
the context-tool response body without hitting sufficiency on the flow
shapes small repos actually contain.
Non-breaking: the agent can still pass an explicit `maxNodes` to
override; medium+ repos (>=150 files) keep the 20-node default.

* docs(mcp): pin the empirical 5-tool gating floor for tiny repos
n=2 audit on cobra/ky/sinatra ruled out cutting below 5 tools (search +
context + node + explore + trace) on the tiny-repo tier. The smaller
3-tool gate (search + context + trace) saved ~$0.025 of prompt overhead
but the agent fell back to extra Reads to cover what codegraph_node and
codegraph_explore would have answered — net cost regression on all three
test repos (cobra 17% → 48% loss, sinatra 18% → 96% loss). Documented
inline so future tuners don't re-try this dead-end.
No behavior change beyond the comment: the 5-tool gate remains the
production setting.

* docs(mcp): pin empirical lower bound on tool gating after n=2 micro test
Tested the hypothesis that exposing FEWER tools on micro repos (<50
files) would close the cost gap. Results:
- 1-tool gate (codegraph_search only):
- ky: +44% (worse than 5-tool +30%)
- express: +107% (catastrophic — was -43% WIN with all 10)
- cobra: +126% (way worse than 5-tool +17%)
The single-tool gate forces the agent to read everything because it
can't navigate the call graph. The 5 omitted tools (context, node,
explore, trace) were doing real work that grep+Read can't replicate.
Conclusion: 5 tools (search + context + node + explore + trace) is the
empirical lower bound on the tiny-repo tier. Cutting below regresses
EVERY tested repo. The remaining ~$0.04-0.08 of structural cost overhead
on tiny repos is unavoidable without sacrificing the value codegraph
provides at that scale (which would also make WITH = WITHOUT, defeating
the install).
Comment documents the dead-ends so future tuners don't relitigate.

* feat(mcp): iter3/iter4 — raise tool-gate to 500, sufficiency steering in context, hard-exclude low-value files
Three layered changes targeting the sinatra/slim/small-repo cost gap
that iter2's body-shrink failed to close (smaller bodies just pushed
the agent to Read instead):
1. **Tool-gate threshold 150 → 500** (`TINY_REPO_FILE_THRESHOLD`).
Sinatra (~159 files) and slim (~200 files) have the same structural
problem as cobra (
* feat(context): iter7 — core-directory boost to surface dominant-file siblings in search ranking
On projects with a single file holding the dense majority of internal
call edges (e.g. sinatra's `lib/sinatra/base.rb` at ~85% of in-file
edges), text search was favoring small focused extension files over the
core file. A small focused file like `multi_route.rb` wins on verbatim
name match + file-size normalization, burying the 1500-line core file's
longer method names (e.g. `route!` vs `route`).
Fix: detect the "dominant file" — the file whose in-file edge count is
≥3× the next candidate's — then add +25 to all results sharing its
directory prefix. This pulls the core file's siblings above
sibling-package extensions without hardcoding any repo structure.
`getDominantFile()` excludes test/spec files and generated files
(e.g. etcd's `rpc.pb.go` has 4× the in-file edges of `server.go` and
would otherwise hijack the boost toward generated protobuf stubs).
SQL pulls the top 20 candidates; path-pattern filtering handles what
SQLite LIKE can't express.
* feat(mcp): iter10+iter12 — routing manifest inline + probe-sweep harness
On small projects (<500 files) with a routing-shaped query, build a
URL→handler manifest directly from the graph (each `route` node joins to
its handler via `references`/`calls` edges) and inline the top handler
file's source. The agent gets the canonical routing answer in ONE
codegraph_context call — no need to parse framework DSL, Glob for
controllers, or chase down handler files.
The lever is "make the backend smarter so the agent doesn't have to":
- Parsing routes.rb / routes/api.php / urls.py DSL is the agent's job
in the WITHOUT arm. Codegraph already has it parsed as `route` nodes
with edges to handlers — we just project that to a manifest table.
- The handler implementations are right there in the index too; inline
the highest-handler-count file so the agent sees real code, not just
symbol names.
Results on the realworld template repos that were losing badly:
rails-rw +89% LOSS → -15% WIN (agent often answers with 0-1 tool calls)
laravel-rw +29% LOSS → +12% (tight gap)
gin-rw +30% LOSS → +23% (still loss but smaller)
flask-mb +64% LOSS → +25% (smaller gap)
The residual losses are mostly the agent's defensive read behavior on
super-cheap-WITHOUT repos (express-rw still does 4 Reads even with a
19-row manifest + service file inlined). That's an agent-side ceiling
the backend can't reach further without removing tools.
Also lands `scripts/agent-eval/probe-sweep.mjs` — a direct-MCP test
harness that runs context probes across 21 repos in ~600ms (vs ~30min
for a real claude audit). Enables rapid iteration on backend changes:
edit tools.ts / context-builder, npm run build, re-run probe-sweep,
compare signals (manifest fired? handler file inlined? response size?)
before paying for a claude run.

* fix(mcp): first tool call awaits catch-up sync (no stale rows for deleted files)
`MCPEngine.catchUpSync()` reconciles the index against the working tree
after open (catching `git pull`/`checkout`/`rebase` and any edits or
deletes made while no server was running). It was fire-and-forget — so a
tool call landing in the first ~50-300ms could race past it and serve
rows for files that no longer exist on disk. The per-file staleness
banner can't help here, because that signal is populated by the file
watcher (not by catch-up).
The fix: `catchUpSync()` now pushes its promise into `ToolHandler` via
`setCatchUpGate(p)`; the first `execute()` call awaits the gate and then
clears it. Subsequent calls pay nothing. Catch-up rejections are logged
by the engine and swallowed by the handler so a transient sync failure
never breaks tools.
Most visible on the "deleted everything between sessions" case, where
MCP previously returned stale rows pointing at non-existent files.
Validated end-to-end on a 10,640-file VS Code index: with the gate, a
codegraph_search for "ExtensionHost" against an empty (but stale-DB)
directory returns "No results found" after the catch-up drains the DB;
without the gate, the same call returns 10 stale hits.

feat(jvm): resolve Java/Kotlin imports by fully-qualified name (#412)
Wrap top-level declarations of `.kt` / `.java` files in an implicit `namespace` node carrying the file's `package`, then resolve `import com.example.foo.Bar` through that qualifiedName index — so a Bar in Models.kt resolves correctly regardless of filename, a top-level function import binds to its declaration, Java↔Kotlin interop crosses cleanly, and same-name classes across packages no longer collide. Wildcard imports still go through name-matcher.
Also extracts Java/C# anonymous-class overrides (`new T() { ... }`) as first-class class nodes with their override methods. Phase 5.5 interface-impl then bridges T's abstract methods to the anonymous overrides automatically — including the lambda-returned `new T() { ... }` pattern common in guava (Splitter, CacheBuilder).
Concrete impact on macrozheng/mall (524 .java files, multi-module Spring + MyBatis): 524 namespace nodes, 862 imports edges newly resolve to Java symbols, 76 distinct `Criteria` classes preserved across packages with no merge. On google/guava (3,227 .java): 3,608 anonymous classes extracted, +2,534 interface-impl edges reach overrides hidden in `new T() { ... }` blocks.
Agent A/B playbook on small (spring-petclinic-kotlin, 38 .kt), medium (mall, 524 .java), large (guava, 3,227 .java) — 3 flow prompts × 2 runs/arm × 2 arms = 36 runs, claude-opus, headless. Spring repos: 0/0 Read/Grep with-arm, −27% wall-clock vs no-codegraph. Guava: 1.8 Read avg with-arm (vs 2.0 without) — improved by the anon-class extraction; residual is a lambda→SAM coverage gap orthogonal to FQN imports (filing follow-up).

fix(cli): include resolution + synthesizer edges in indexAll report (#413)
The orchestrator's per-file counter only sees extraction-phase edges, so the `X nodes, Y edges` line printed after `codegraph init -i` / `codegraph index` undercounts the graph — often by more than half on repos with heavy cross-file resolution (mall: 20 047 reported vs 45 629 actually in the DB). Snapshot (nodes, edges) before/after the full pipeline in `indexAll` and write the true delta back to the result. New lightweight `QueryBuilder.getNodeAndEdgeCount()` is one round-trip with no per-kind breakdowns. `indexFiles` (no resolution) and `sync` (uses `nodesUpdated`, not `nodesCreated`) are unaffected. Regression test added: `__tests__/integration/full-pipeline.test.ts > reports edgesCreated including resolution + synthesizer phases`. |

feat(resolution): add C/C++ include path resolution (#453)
* feat(resolution): add C/C++ include path resolution Add full import resolution pipeline for C and C++ #include directives, connecting extracted import nodes to actual header files in the project. - Add C/C++ extension resolution (.h, .hpp, .hxx, .cpp, .cc, .cxx) - Add system header filtering with ~80 C and ~80 C++ stdlib headers - Add extractCppImports() for #include import mapping extraction - Add compile_commands.json parsing for -I/-isystem include directories - Add heuristic include dir discovery (include/, src/, lib/, api/) - Add resolveCppIncludePath() for include directory search - Add C/C++ built-in symbol filtering (printf, malloc, std::*, etc.) - Wire getCppIncludeDirs into ResolutionContext - Add 13 new tests for C/C++ import resolution and extraction Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * review: wire #include resolution into pipeline + fix builtin filter The PR landed the include-dir scan logic (loadCppIncludeDirs + resolveCppIncludePath) but the indexer never reached it: imports references with referenceName='X.h' fell into resolveViaImport's symbol-lookup branch (matched extractCppImports' basename-without-ext localName via .startsWith, then tried to find a symbol named like the extension and failed). End result on bitcoin-core: 0 new file→file imports vs main, despite the include-dir scan resolving paths correctly when probed directly. resolveViaImport now has a C/C++ imports branch that resolves the include path to the actual file node and returns that — skipping the irrelevant symbol scan. Measured on bitcoin-core: +2,059 newly resolved file→file imports (6,027 → 8,086, +34%). The unconditional CPP_BUILT_INS / C_BUILT_INS filter also misfired: C/C++ codebases routinely shadow stdlib names (bitcoin's mp::move, custom allocators with free/malloc, stream classes with read/write/ close/open, logging libs wrapping printf). Filtering those names killed legitimate edges — 1,179 → 0 for move(), 33 → 0 for free(), 149 → 7 for write() on bitcoin. The filter now defers to hasAnyPossibleMatch: only filter when no user-defined symbol with the name exists. std:: prefix stays unconditional (never user-shadowed in practice). After: printf/free/open/close/read/write/swap all preserved at main's counts; the std::move-binds-to-mp::move false-positives still drop (correctly: −2,154 C/C++ calls). Also: drop the duplicate 'FILE' in C_BUILT_INS; add an end-to-end test that asserts `#include "X.h"` produces a file→file imports edge in the real indexing pipeline (not just direct resolver probes); add a test documenting the cross-language `.h` heuristic claim (Obj-C dirs are intentionally allowed as C/C++ include dirs); add CHANGELOG entry under [Unreleased] with measured numbers.

fix(extraction): capture top-level initializer and inline-object-method calls (#465)
The variable / method-definition extractors never walked top-level
initializer values or inline-object method bodies, so calls like
`const token = getTokenMp()` and `methods: { save() { getTokenMp() } }`
showed up nowhere in `codegraph_callers`. The variable extractor now
walks any non-object initializer value; the method-definition extractor
still skips synthetic nodes for inline-object methods (noise rationale
unchanged) but now walks their bodies for calls. Surfaces in plain
`.ts`/`.js` files as well as Vue SFCs (`<script setup>` initializers +
Options API `methods: {...}` / `setup()`), which is where the bug was
originally reported.

fix(installer): tell Kiro IDE users to enable MCP in Settings (#475)
PR #473 emitted only "Restart Kiro for MCP changes to take effect." That note is incomplete for Kiro IDE users: the IDE ships with MCP support disabled by default, so a freshly-written ~/.kiro/settings/mcp.json is ignored until the user opens Settings, searches "MCP", and flips the "Kiro Agent: Configure MCP" dropdown to "Enabled". The agent then reports "No MCP powers installed" and falls back to grep/Read — which looks like an installer wiring bug but isn't. Kiro CLI doesn't gate on this flag — it reads the same file without any toggle — so the second note calls out which audience needs the extra step.

feat(installer): add Kiro CLI/IDE target (#385) (#473)
`codegraph install` now detects and configures Kiro alongside the existing seven agents. Writes `mcpServers.codegraph` to `~/.kiro/settings/mcp.json` (global) or `./.kiro/settings/mcp.json` (local), plus a dedicated `~/.kiro/steering/codegraph.md` / `./.kiro/steering/codegraph.md` instruction file — Kiro's steering system loads every `*.md` file in `steering/` as agent context, so a dedicated file is the natural surface (no marker-based merging needed). Sibling MCP servers in `mcp.json` and unrelated steering files (`product.md`, `tech.md`, etc.) are preserved across install and uninstall. Validated end-to-end on macOS, Linux (Docker node:22-bookworm arm64), and Windows 11 (Parallels VM, Node 24): full installer-targets suite passes (132 tests) on all three platforms, and live install / idempotent re-run / uninstall round-trip works as expected.

fix(resolution): Java/Kotlin imports disambiguate same-name classes (#314) (#472)
A Maven multi-module project where `dao/converter/FooConverter` and `service/converter/FooConverter` both expose a `convert` method used to resolve by file-path proximity — picking whichever class was closer to the caller, which is wrong any time the caller lives in an equidistant cross-cutting module. `extractImportMappings` had no Java branch at all, so the FQN signal Java imports carry — `import com.example.dao.converter.FooConverter;` — was thrown away. - `extractJavaImports` parses regular and `import static` directives; wildcard imports (`*`) are intentionally skipped. - `resolveViaImport` has a new Java/Kotlin cross-file branch that converts the imported FQN to a file-path suffix (`com/example/dao/converter/FooConverter.java`, or `.kt`) and resolves the symbol against the file whose path matches by suffix. - For the field-receiver pattern (`@Autowired private FooConverter fooConverter; fooConverter.convert(...)`), `matchMethodCall` now looks up the receiver's inferred type in the caller file's imports and threads the resulting FQN through to `resolveMethodOnType`. When two `FooConverter::convert` candidates exist, the import — not iteration order — picks the right one. Validated with a synthetic 3-module repro: swapping only the import line on the caller swaps the resolved target between dao and service. spring-petclinic (47 .java files): +15 newly import-resolved edges, +2 references, no regression elsewhere.

fix(extraction): TS type-alias object members are first-class nodes (#359) (#471)
A call site `recorder.stop()` where `recorder: RecorderHandle` and
`type RecorderHandle = { stop: () => Promise<void> }` used to attach
its edge to an unrelated `class Foo { stop() {} }` in a sibling
directory — there was no `RecorderHandle::stop` node, so the existing
camelCase/path-proximity scoring picked the only `stop` method in the
graph (which happened to be wrong). False-positive `calls` edges
silently widened `codegraph_impact` blast radius.
`extractTypeAlias` now surfaces object-shape (and intersection-type)
members as first-class graph nodes:
type X = { foo: T; bar(): T };
-> X (type_alias)
X::foo (property)
X::bar (method)
Function-typed properties (`stop: () => Promise<void>`) emit as `method`
kind so `obj.stop()` resolves to them at the call site — same node
kind the existing receiver-name/word-overlap heuristic in
`matchMethodCall` already prefers. No new resolver logic needed.
Walk only immediate `object_type` / `intersection_type` operands of the
alias value. Anonymous nested object types inside generic arguments
(`Promise<{ ok: true }>`) intentionally don't produce phantom members.
Validation on excalidraw/excalidraw (314 .ts files):
+776 new property nodes (alias non-function members)
+1,008 new method nodes (alias function-typed properties + method_signatures)
+226 calls edges newly accurate against alias members
User's exact 3-file repro:
before: finaliseRecording -> StdioMcpClient::stop (wrong, sibling dir)
after: finaliseRecording -> RecorderHandle::stop (correct)
StdioMcpClient::stop callers: voice/ false-positives gone

fix(extraction): C# produces references edges for type annotations (#381) (#470)
Indexing any C# project produced zero `references` edges, so `codegraph_callers SomeDto` returned no hits even when the DTO was used as a param/return type across the codebase, and `codegraph_callees` on a service class only saw its `using` imports — the headline structural query silently degraded to text-search on half of every typical backend stack. Two root causes: 1. `csharp.ts` was missing `returnField` (default `'return_type'` doesn't exist on C# AST; the field is `'type'`) AND had `paramsField:'parameter_list'` (the node TYPE, not the field NAME `'parameters'`) — so parameter type extraction silently no-op'd. 2. `extractTypeRefsFromSubtree` only emitted refs for `type_identifier` leaves. C# tree-sitter doesn't produce `type_identifier` — it uses `identifier`, `predefined_type`, `qualified_name`, `generic_name`, `array_type`, `nullable_type`, `tuple_type`, etc. Fix: - `csharp.ts`: `paramsField:'parameters'`, `returnField:'type'`. - Route C# through a dedicated `extractCsharpTypeRefs` + `walkCsharpTypePosition`. Descends ONLY into known type fields (`parameter.type`, `method.type`, `property.type`, `variable_declaration.type`, `tuple_element.type`), so parameter NAMES like `request` in `Build(UserDto request)` never leak as type refs. - Hook `extractField` and `extractProperty` to call `extractTypeAnnotations` so property/field type refs land in the graph. Validation on dotnet/eShop (527 .cs files): C# `references` edges: 35 -> 925 (+26x) No regression in calls/imports/instantiates/extends/implements. Closes #381. |

fix(resolution): Go cross-package qualified calls resolve via go.mod (#388) (#469)
`pkga.FuncX(...)` cross-package calls in Go monorepos were dropping through the import resolver — `isExternalImport(go)` flagged any non-`/internal/` import as third-party because the resolver had no idea what the project's own module path was. Resolution fell back to name matching with path-proximity scoring, which on a layered codebase picks one accidental candidate per call site (~<1% recall per #388's 5,303-vs-1 figure). - `src/resolution/go-module.ts` (new) parses the `module ...` directive from project-root `go.mod`, exposed via `getGoModule()` on `ResolutionContext`. - `isExternalImport(go)` treats `<module-path>/...` imports as in-module; the existing `/internal/` escape hatch is preserved for repos without a parsed go.mod. - `resolveViaImport` gets a Go cross-package branch that strips the module prefix to a project-relative directory, then resolves the qualified member via `getNodesByName(member)` filtered to that exact directory and `isExported=true`. Sub-packages don't collide with their parents; same-name funcs in different packages don't false-merge. - Go extractor sets `isExported` from the identifier's first character (Go's universal uppercase=exported convention). The resolver depends on this to filter candidates. Validation on gRPC-Go (1,031 .go files, layered package tree): total `calls` edges: 23,803 -> 34,105 (+43%) cross-pkg `calls`: 10,880 -> 19,929 (+83%) fmt/strconv/etc. stdlib calls: stay external (no false positives) Tests cover in-module disambiguation with same-name funcs in two packages, aliased imports, and stdlib calls not being false-resolved to in-project nodes.

fix(extraction): extract type refs from TS interface property and method signatures (#432)
Types that appeared only in TypeScript interface members — property signatures like `value?: Partial<IPage>` and method signatures like `fetchPage(arg: IPage): IOrderField` — were not being captured at extraction time, so the resolver never built `references` edges for them. `codegraph_impact`/`codegraph_callers` on the named type missed every consumer that imported it solely to use it in an interface shape. Add a `property_signature` / `method_signature` branch in `visitNode`: when inside a class-like node (which covers interfaces) and the language supports type annotations, call `extractTypeAnnotations` with the parent (interface) node ID as the edge source. No property/method node is created — only unresolved references that the resolver wires the same way it wires field and parameter type references elsewhere. |
