Add `codegraph callers`, `codegraph callees`, and `codegraph impact` CLI commands, bringing the CLI to parity with the codegraph_callers/callees/impact MCP tools — so the graph-traversal queries work in scripts, CI, and git hooks without a running MCP server. All three support `--path` and `--json`; `impact` groups output by file to match the MCP layout.

Remove .codegraph/config.json and the entire config surface. CodeGraph now
indexes every file whose extension maps to a supported language and respects
.gitignore everywhere — git repos via git itself, non-git projects via the
`ignore` library (root + nested .gitignore files, the same way git does).
- Remove CodeGraphConfig/DEFAULT_CONFIG, src/config.ts, and the public config
API (the `config` option on init, getConfig/updateConfig/getConfigPath).
- Derive the source-file allowlist from EXTENSION_MAP (isSourceFile); maxFileSize
is now a constant. Drop the .codegraphignore marker.
- Behavior change: committed, non-gitignored dirs (vendor/, a committed dist/)
are now indexed — .gitignore is the single source of truth.
Earlier inert fields (languages, frameworks, extractDocstrings, trackCallSites,
customPatterns) and their dead helpers are removed as part of this.
Resolves#283.

Detects Drupal projects via composer.json drupal/* deps; extracts routes from *.routing.yml (route nodes + references edges to controllers/forms/entity handlers) and Drupal hook implementations from .module/.install/.theme/.inc. Adds yaml/twig as file-level languages and excludes core/contrib by default. Resolves#268.
Adds Hermes Agent (Nous Research) as a CodeGraph installer target. Writes mcp_servers.codegraph and ensures platform_toolsets.cli includes mcp-codegraph in $HERMES_HOME/config.yaml, with full installer contract-test coverage.
The old entry described the retired multi-backend chain (better-sqlite3 → wasm
with npm-rebuild instructions). CodeGraph now bundles Node + node:sqlite (WAL),
so the lock class is gone. The entry now covers the only real cases: an old
pre-0.9 install (reinstall) or WAL disabled by the filesystem (move to local disk).

* fix(db): eliminate concurrent-read "database is locked"; add node:sqlite backend (#238)
WAL + busy_timeout were already enabled, so the issue's suggested fix was a
no-op. The real causes, addressed here:
- busy_timeout is now set first (before journal_mode) and lowered 120s -> 5s,
so open-time pragmas wait out a lock instead of hanging for two minutes.
- getCodeGraph no longer opens a second connection to the default project when
a tool passes its own projectPath (the in-process lock amplifier).
- The wasm fallback (no WAL) gets a bounded read-retry on SQLITE_BUSY.
- New: node:sqlite backend, preferred over wasm, so installs whose native
better-sqlite3 build fails land on a real-WAL backend instead of no-WAL wasm.
- codegraph status / codegraph_status now report the effective journal mode, so
a lock report is triageable (wal vs delete).
- CLI hard-blocks Node < 20 to actually enforce the engines floor.

* refactor(db)!: node:sqlite is the sole backend; drop better-sqlite3 + wasm
Now that distribution will bundle a Node 24 runtime, node:sqlite (real SQLite
with WAL + FTS5) is always available. Collapse the three-backend adapter to
node:sqlite only and remove the machinery the other two needed:
- Remove better-sqlite3 (optionalDependency) and node-sqlite3-wasm (dependency).
- Remove WasmDatabaseAdapter, the named->positional param translation, the
SQLITE_BUSY read-retry, the wasm fallback banner, the backend env override,
and the native/node-sqlite/wasm selection chain.
- createDatabase now opens node:sqlite directly, with a clear error pointing at
the bundled release / Node 22.5+ when the module is absent.
- NodeSqliteAdapter.close() is idempotent and pragma() supports { simple }, to
match the better-sqlite3 behavior callers relied on.
- status (CLI + MCP) reports the single node:sqlite backend; journal-mode
diagnostics and the getCodeGraph single-connection fix are retained.
- Tests repointed off better-sqlite3 onto node:sqlite.
Net -1044 lines. Running from source now requires Node 22.5+.

* feat(dist): self-contained bundle prototype (vendored Node + install channels)
Phase 3 of the node:sqlite migration: ship a vendored Node runtime so CodeGraph
runs with no system Node and no native build (node:sqlite is built in).
- scripts/build-bundle.sh: build a per-platform archive (official Node + dist +
prod deps + launcher). Same recipe per platform; pins Node v24.16.0.
- install.sh: curl|sh installer (no Node required) — detects os/arch, pulls the
archive from Releases, symlinks onto PATH; re-run to upgrade, --uninstall to
remove. The VPS/SSH path.
- scripts/npm-shim.js: thin launcher for the npm channel — resolves the
per-platform optionalDependency bundle and execs it, so `npm i -g` keeps
working and the real work runs on the bundled Node regardless of the user's.
- BUNDLING.md: distribution design + release-pipeline TODO (CI matrix, platform
packages, code signing, brew, retiring the Node-version gate).
Validated end-to-end: darwin-arm64 and linux-x64 bundles both run init + index +
status (Backend: node:sqlite, Journal: wal) + FTS query with NO system Node —
linux-x64 verified in a clean ubuntu:24.04 amd64 container. Release archives are
gitignored; CI will produce and upload them.

* feat(dist): add Windows PowerShell installer (install.ps1)
The `irm … | iex` one-liner for Windows, mirroring install.sh: detect arch,
pull the matching bundle from Releases, extract to %LOCALAPPDATA%\codegraph,
add it to user PATH. Re-run to upgrade. (Windows bundle production in
build-bundle.sh is still TODO.)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(dist): release workflow + npm packaging; README/CHANGELOG for bundled distro
- .github/workflows/release.yml: manually-triggered (workflow_dispatch) release
matrix. Builds a self-contained bundle per platform on its own runner
(darwin-arm64/x64, linux-x64/arm64), publishes a GitHub Release with all
archives, and publishes the npm thin-installer (shim + per-platform packages).
Windows targets are TODO (build-bundle.sh is unix-only).
- scripts/pack-npm.sh: assemble the npm packages from built bundles — per-platform
packages tagged os/cpu + the main shim package with them as optionalDependencies
(esbuild pattern). Proven locally: npm-install the tarballs, run via the shim,
resolves the bundle and runs on the bundled Node 24 (node:sqlite / WAL).
- README: install section now leads with the no-Node one-liners (curl|sh, irm|iex)
then npm/npx; "bundled · none required" badge.
- CHANGELOG: standout headline for the self-contained release, plus Added/Changed/
Removed for the install channels, node:sqlite backend, and dropped deps.

* feat(dist): Windows bundles + single-trigger release workflow
- build-bundle.sh: add win32-x64 / win32-arm64 targets — download Node's Windows
zip, bundle node.exe + a .cmd launcher, output a .zip. Verified structurally
(PE32+ node.exe, CRLF .cmd, portable node_modules). Since there are no native
addons, any target builds on any OS, so the whole matrix builds on one runner.
- pack-npm.sh: handle .zip bundles and win32 packages (os: win32, node.exe).
- release.yml: simplified to your spec — manual trigger reads the version from
package.json, builds all platform bundles, creates the GitHub Release with notes
pulled from CHANGELOG.md, and publishes the npm shim + platform packages.
- BUNDLING.md: Windows + build-anywhere notes; release pipeline documented.

Detect NestJS projects and emit `route` nodes (each linked by a `references`
edge to its handler method) across all four transport layers:
- HTTP controllers: @Controller prefix joined with
@Get/@Post/@Put/@Patch/@Delete/@Head/@Options/@All
- GraphQL resolvers: @Query/@Mutation/@Subscription
- Microservices: @MessagePattern/@EventPattern
- WebSocket gateways: @SubscribeMessage (prefixed with gateway namespace)
Detected from any @nestjs/* dependency in package.json (falls back to scanning
*.controller.ts/*.resolver.ts/*.gateway.ts). Handles class+method path joining
with empty @Controller()/@Get(), a string-aware balanced-paren arg reader so
GraphQL type thunks (@Query(() => [User])) aren't truncated, stacked decorators
(@UseGuards) when locating the handler, and disambiguates the @Query() GraphQL
method decorator from the REST @Query() param decorator (GraphQL only counts
inside @Resolver classes). Also resolves injected *Service/*Controller refs to
their classes by Nest file-naming convention.
Adds 18 framework tests; updates the README framework table and CHANGELOG.

* perf(mcp): steer agents to answer directly instead of delegating to subagents
CodeGraph beats native grep/read on cost only when the agent queries it
directly. When the agent delegates to file-reading sub-agents, those
sub-agents read files regardless of the index, so CodeGraph becomes net
overhead on top of the reads. The install templates even told agents to
"spawn a subagent for explore-class questions" — the expensive path.
Changes:
- server-instructions + both install templates: add an "Answer directly —
don't delegate exploration" directive; reposition codegraph_explore as the
efficient one-call multi-symbol tool (was: "spawn a subagent for it").
- codegraph_explore: hard-cap output to its adaptive budget (it overran,
~30k vs a 28k cap) and tighten the medium tier (28k->13k).
- codegraph_node: return a member outline for container kinds instead of the
full class body.
Rigorous N>=4-per-arm warm-block benchmark (median total_cost_usd):
excalidraw (~600 files): WITH $0.54 vs native $1.02 (-47%)
vscode (~10k files): WITH $0.41 vs native $0.72 (-42%)
ky (~25 files): WITH $0.46 vs native $0.44 (wash)
Answers were equal-or-better (correct, file:line-cited) with ~6x fewer tool
calls; the directive drove the direct path on 14/14 codegraph runs.

* docs(readme): rebuild benchmark with real-world repos + cost/token/time/tool savings
Replace the "Claude Code (Python+Rust/Java)" rows — which benchmarked the
Claude Code CLI repo, not real codebases in those languages — with real
open-source projects per language: Django (Python), Tokio (Rust), OkHttp
(Java), Gin (Go), plus Alamofire (Swift) and the existing TypeScript repos
(VS Code, Excalidraw).
The table now reports all four savings the change targets — cost, tokens,
time, tool calls — as the median of 4 runs per arm (Claude Opus 4.7,
headless claude -p, with vs empty MCP config). Averages across the 7 repos:
35% cheaper, 59% fewer tokens, 49% faster, 70% fewer tool calls. Adds a
methodology note and raw WITH->WITHOUT medians.

* feat(installer): multi-target — Claude Code, Cursor, Codex CLI, opencode
Closes the Claude-locked installer behind issue #137. The runtime MCP
server was already agent-agnostic (stdio); only the installer was
locked. After this refactor, `codegraph install` can write per-agent
MCP config + instructions for any combination of supported agents.
## What ships
Four agent targets, each implementing the new `AgentTarget` interface:
- **Claude Code** — `~/.claude.json`, `~/.claude/settings.json`,
`~/.claude/CLAUDE.md` (or local equivalents). Behavior preserved
from the original installer; existing installs upgrade in place.
- **Cursor** — `~/.cursor/mcp.json` (g) or `./.cursor/mcp.json` (l)
+ project-local `./.cursor/rules/codegraph.mdc`.
- **Codex CLI** — `~/.codex/config.toml` with `[mcp_servers.codegraph]`
+ `~/.codex/AGENTS.md`. Global only. Hand-rolled TOML serializer
scoped to the table we own — siblings + array-of-tables preserved.
- **opencode** — `~/.config/opencode/opencode.json` (XDG) or
`./opencode.json`.
Adding a 5th agent is a new file in `src/installer/targets/` plus
one entry in `registry.ts`.
## CLI changes
```
codegraph install # interactive multi-select
codegraph install --yes # auto-detect, install global
codegraph install --target=cursor,claude --yes # explicit list
codegraph install --target=auto --location=local # detected, project-local
codegraph install --target=none # skip agent writes entirely
codegraph install --print-config codex # dump snippet, no writes
```
## Backwards compat
Every export from the old `config-writer.ts` (`writeMcpConfig`,
`writePermissions`, `writeClaudeMd`, `hasMcpConfig`, `hasPermissions`,
`hasClaudeMdSection`) is preserved as a `@deprecated` shim that
delegates to per-file helpers in `targets/claude.ts`. Existing Claude
users see byte-identical on-disk layout — `detect()` reports
`alreadyConfigured: true`, re-running is a no-op.
## Tests
+47 new tests in `__tests__/installer-targets.test.ts`:
- Parameterized contract test across all 4 targets × supported
locations (install → unchanged on re-run, sibling preservation,
uninstall reverses install, printConfig writes nothing).
- Codex partial-state recovery, locked-block contract for the
codegraph table, full TOML serializer suite.
- Registry: getTarget, resolveTargetFlag (auto/all/none/csv).
`__tests__/installer.test.ts` relaxed one assertion: the new code
returns `unchanged` for byte-identical re-runs instead of `updated`;
the surrounding-custom-content contract is unchanged.
## Uninstall behavior change
`bin/uninstall.ts` now loops `ALL_TARGETS.uninstall('global')` on
`npm uninstall -g`. A user who manually configured
`~/.codex/config.toml` with our block will have only that block
removed on package uninstall — we only touch the dotted-key table
we own.
Based on andreinknv/codegraph@c5165e4. Issue #137.

* chore(scripts): add local-install.sh for hands-on branch testing
Builds the current branch and `npm link`s it as the global
`codegraph` binary. `--undo` unlinks and reinstalls the published
version. Mirrors the style of scripts/release.sh.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(installer): move agent picker to the first prompt
Reorders runInstallerWithOptions so the multi-select for agents
(Claude / Cursor / Codex / opencode) is step 1 — before the
global-npm-install confirm and before the location prompt. Bare
`npx @colbymchenry/codegraph` now opens with "Which agents should
CodeGraph configure?", which is the answer most users want first.
Side effects of the reorder:
- Early exit if zero targets selected — skips global-install and
location prompts entirely, exits with "nothing to do."
- Multiselect labels drop the per-location "will skip" hint (location
isn't known yet) and replace it with a static "global only" badge
for targets like Codex that have no project-local config concept.
- If every selected target is global-only, the location prompt is
skipped and global is forced (no point asking).
- Detection probes the user-provided location if known via flag,
else 'global' as the most common default — labels are a hint
about what's installed locally, not load-bearing.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(installer): disambiguate "global" wording in install prompts
Two prompts both said "global" but meant different things — users
read them as duplicates. Renamed for clarity:
- Step 2 (npm install -g): "Install codegraph globally?" →
"Install the codegraph CLI on your PATH? (Required so agents can
launch the MCP server)". Spinner messages match.
- Step 3 (config location): "Where would you like to install?" with
"Global"/"Local" → "Apply agent configs to all your projects, or
just this one?" with "All projects" (~/.claude, ~/.cursor, etc.)
/ "Just this project" (./.claude, ./.cursor, etc.).
- All-global-only fallback: "Using global install" → "Writing
user-wide configs (selected agents have no project-local config)."
Underlying `Location` values ('global' / 'local') unchanged; only
the UI strings shift, so no test or flag breakage.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(installer/cursor): inject --path so workspace-aware queries work
Cursor launches MCP-server subprocesses with cwd != workspace root,
AND does not pass rootUri or workspaceFolders in the MCP initialize
call. The codegraph MCP server's process.cwd() fallback misses the
workspace's .codegraph/ and reports "not initialized" on every tool
call. Codex and Claude don't have this issue (Codex launches with
cwd=workspace, Claude passes rootUri).
Fix: inject `--path` into the args we write for Cursor.
- local install (./.cursor/mcp.json): hardcode the absolute project
path — known at install time.
- global install (~/.cursor/mcp.json): use `${workspaceFolder}` so
Cursor expands it per-workspace. One global config now drives
every project the user opens, without per-project re-install.
No test breakage — the parameterized contract tests check
idempotency / sibling preservation, not the exact args content.
File-header comment documents the rationale so the next person
doesn't strip the arg as boilerplate.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(init): auto-wire project-local agent surfaces
Closes the global-Cursor UX gap: `~/.cursor/mcp.json` registers the
MCP server, but Cursor's agent only learns to *prefer* codegraph
over native grep when it sees `.cursor/rules/codegraph.mdc` — a
project-local file that global install can't write. Previously the
user had to re-run `codegraph install --target=cursor --location=local`
for every new project. Now `codegraph init` does it automatically.
## What changed
- New optional `AgentTarget.wireProjectSurfaces()` returning a
WriteResult of project-local files to drop. Most targets omit
it (their global config is complete). Cursor implements it to
write the rules file.
- New `wireProjectSurfacesForGlobalAgents()` orchestrator in
installer/index.ts — iterates ALL_TARGETS, detects which are
configured globally, calls their wireProjectSurfaces, returns
what was written.
- `codegraph init` calls the orchestrator in both branches:
- Fresh init: write surfaces after CodeGraph.init succeeds.
- Already-initialized re-init: write surfaces too, so re-running
`init` is the documented recovery path for a project missing
its rules file.
## Steady-state UX
1. Once, ever: `codegraph install` (writes global agent configs)
2. Per project: `codegraph init -i` (builds the index + auto-wires
project-local agent surfaces — currently Cursor's rules file)
No new tests — wireProjectSurfaces delegates to writeRulesEntry,
which is already covered by the parameterized contract tests.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(installer): agent-agnostic instructions template
The old template was inherited from the Claude-only era and
prescribed "ALWAYS spawn an Explore agent" — a Claude Code-specific
concept (subagents via the Task tool). When Cursor's agent read
this it had no Explore agent to spawn, got confused, and fell back
to native grep/read even for structural queries the codegraph MCP
tools answer in one call.
This rewrite:
- Frames each tool by the question it answers (search vs callers
vs impact vs context vs explore vs node vs files vs status).
- Tells the agent explicitly to TRUST codegraph results and not
re-verify them with grep — the over-grep-after-codegraph
behavior was the main symptom we saw on Cursor.
- Reframes "spawn Explore agent" as an OPTIONAL pattern for
harnesses that support parallel subagents — Claude Code still
gets the hint, Cursor / Codex / opencode just skip it.
- Trims the "if not initialized" section to one prescriptive line.
Same marker delimiters (`<!-- CODEGRAPH_START/END -->`) so existing
installs upgrade in place via the marker-based section swap. No
test changes needed — the parameterized contract tests check
marker placement + sibling preservation, not the literal body.
Effective surfaces: ~/.claude/CLAUDE.md (Claude), .cursor/rules/
codegraph.mdc (Cursor, project-local), ~/.codex/AGENTS.md (Codex).
Users get the new copy by re-running `codegraph install` for
global writes, or `codegraph init` for Cursor's project rules.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(readme): reflect multi-agent support at the top + accurate flow
- Tagline now reads "Supercharge Claude Code, Cursor & Codex" instead
of Claude-only — multi-agent support is what the PR is about, the
README should say so above the fold.
- New badge row (Claude Code / Cursor / Codex CLI / opencode) in the
same shields.io style as the OS row.
- Install-flow bullets reordered to match the actual prompt order
(agent picker first, then PATH install, then location).
- `codegraph init -i` step now mentions that init wires up
project-local agent surfaces (Cursor rules file etc.) so global
install works in every project without a re-run.
- Agent-agnostic phrasing in the closing line ("your agent" not
"Claude Code").
Headline-level brand decision left intentionally in this PR — the
existing Claude-only positioning predates multi-agent support.

Closes the visibility gap behind issues #138 (WASM-on-macOS) and #139
(MCP "database is locked"). `better-sqlite3` is in optionalDependencies,
so when the native build fails npm install still succeeds and the
runtime silently falls back to node-sqlite3-wasm — 5-10x slower and
without WAL, so writers block readers (which is what makes the MCP
server appear to "lock the DB" in #139). The only existing signal was
a one-line `console.warn` to stderr that MCP transports typically
swallow.
This patch does NOT change install behavior — better-sqlite3 stays in
optionalDependencies so cross-platform installs keep working. It just
makes the substitution observable + recoverable.
## Visibility (4 surfaces)
- CLI `codegraph status`: new `Backend:` line under Index Statistics.
`native` rendered green; `wasm` rendered yellow with an inline
`npm rebuild better-sqlite3` nudge. Also exposed in `--json` as
`backend: 'native' | 'wasm'`.
- MCP `codegraph_status`: new `**Backend:**` line. Native form reads
`native (better-sqlite3)`; wasm form prepends a warning glyph and
includes the full fix recipe.
- Stderr banner on fallback (`buildWasmFallbackBanner`): replaces the
bare one-line `console.warn` with a multi-line bordered banner
covering macOS + Linux fix steps and optionally appending the
native load error.
- README troubleshooting: new "Indexing is slow / MCP database is
locked / WASM fallback active" entry that walks users to the
`Backend:` line and the fix.
## Per-instance backend tracking
`createDatabase` previously set a module-level `activeBackend` global.
MCP can open multiple project DBs in one process via the
`getCodeGraph()` cache, so the global would race / overwrite. Refactor:
`createDatabase` now returns `{db, backend}`, `DatabaseConnection`
carries `private backend` and exposes `getBackend()`, and
`CodeGraph.getBackend()` is the public surface. The CLI and MCP both
call `cg.getBackend()`.
## What this does NOT fix
The root cause of users landing on WASM is environment-specific (Mac
without Xcode CLT, Node version mismatch, etc.) and not fixable in
code without changing the optionalDependencies design. The README
entry tells users what to run; `Backend: native` after rebuild is the
confirmation signal.
## Tests
New `__tests__/sqlite-backend.test.ts` (6 tests) pins the banner
recipe content (so future edits can't strip the recovery commands),
the `WASM_FALLBACK_FIX_RECIPE` constant, and per-instance
`DatabaseConnection.getBackend()` / `CodeGraph.getBackend()` reporting.
Suite: 503 → 509, all passing.
Credit to @andreinknv whose analysis on #138 (and patches on his fork
at 6d0e7a2 + 69f7001) framed the visibility approach.

- Reorder Get Started so the per-project init code block sits between
the npx install and the GIF — visually contiguous code blocks read
better than code → image → code.
- Add Scala (`.scala`, `.sc`) to the Supported Languages table now
that #91 has landed.

The top-level Get Started section showed the install command but not
the per-project init step. Adding the same `cd your-project /
codegraph init -i` block that lives in Quick Start so users see the
full happy path before scrolling.

line number conversion. Handles Python triple-quoted docstrings, Ruby
=begin/=end, Rust nested block comments, and the standard //, #, /* */
forms across the supported languages.
This is consumed by framework extract() methods in a follow-up commit so
that commented-out / docstring routing examples don't surface as phantom
route nodes in the graph.
* feat(frameworks): strip comments before regex extraction (prevents phantom routes)
Pipes the per-language stripCommentsForRegex helper into every framework
extract() that scans raw source: django/flask/fastapi (python.ts),
express, laravel, rails, spring, go, rust, aspnet, vapor, plus
swiftui/uikit struct extraction in swift.ts.
Without this, examples like:
# path('/admin/', AdminPanel.as_view())
""" path('/users/', UserListView.as_view()) """
urlpatterns = [path('/real/', RealView.as_view())]
produced 3 phantom route nodes. Now only the real one is extracted.
Each framework gets a regression test in __tests__/frameworks.test.ts
asserting that line-, block-, docstring- and (where relevant)
heredoc-style commented-out routes do not surface as nodes.

Implements FileWatcher using native OS file events (FSEvents/inotify/ReadDirectoryChangesW) with 2-second debouncing to prevent thrashing on rapid saves. Filters changes against include/exclude patterns and ignores .codegraph directory modifications. Integrates with CodeGraph API (watch/unwatch/isWatching methods) and MCP server for automatic activation. Updates documentation to reflect shift from semantic to full-text search and removal of manual hook installation requirements.
Restructures the benchmark table for better readability by separating queries into a details section and highlighting the overall 92% fewer tool calls and 71% faster performance. Makes the compelling efficiency gains more prominent while maintaining all detailed information in an expandable section.
Updates benchmark results with the largest tested codebase (25,874 files, 272,898 nodes) demonstrating CodeGraph's scalability. Increases the recommended call limit from 3 to 6 to accommodate more complex cross-cutting queries while maintaining efficiency gains over traditional file-reading approaches.
Two fixes discovered while benchmarking Swift (Alamofire):
1. codegraph_explore traversalDepth 2→3: Deep call chains (e.g., Alamofire's
9-step Session.request()→URLSession flow) couldn't be followed in a single
explore call, forcing agents to fall back to file reads.
2. findSymbol/findAllSymbols now support "Parent.child" notation (e.g.,
"Session.request") by matching against qualified names (::Parent::child).
Previously only checked node.name === symbol, which never matched qualified
queries since node names are unqualified.
Also adds Alamofire Swift benchmark data to README (91% fewer tool calls,
78% faster with CodeGraph).

Replaces limited 3-test benchmark with results from 4 real-world codebases (VS Code, Excalidraw, Claude Code) showing 94% fewer tool calls and 77% faster exploration. Updates performance claims and adds detailed breakdown of tool usage patterns with and without CodeGraph.
Testing showed semantic search produces significantly better results for
natural language queries that Claude writes. FTS alone often ranks
properties above their parent classes and misses conceptual matches.
Embeddings are now always on — the vector manager is created eagerly,
with model download and embedding generation still happening lazily.

Eliminates anonymous error reporting functionality that was collecting stack traces and error context via Sentry. Removes all telemetry-related code, configuration options, and documentation references.
Sentry error reporting can now be disabled by:
1. Declining during the interactive installer (sets CODEGRAPH_TELEMETRY=off
in the MCP server config env)
2. Setting CODEGRAPH_TELEMETRY=off in your shell environment
README updated with a Telemetry section documenting what is collected
and how to opt out.

The installer previously ran `npm install -g` silently without user
consent. Now it asks for confirmation first, explains why the global
install is needed (hooks & MCP server), and gracefully skips if declined.
README updated to document this step.
Closes#69

Traverses dependency graph to identify which test files depend on changed source files. Supports stdin input for git integration, custom test file patterns, and configurable traversal depth. Useful for targeted test execution in CI/CD pipelines.
Integrate main branch changes (WASM grammar architecture, centralized
resolution caches, SQLite adapter) with delphi-support branch. Pascal
grammar is now built as WASM and shipped in src/extraction/wasm/ for
consistency with the WASM-based grammar loading approach.

The hybrid approach (Claude's native Explore agents using codegraph tools)
is more effective than a custom explore tool because Explore agents already
know what format the main session needs.

The installer runs `npm install -g @colbymchenry/codegraph` so users
can simply run `codegraph init -i` instead of the full npx command.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Users running via npx don't have the codegraph command installed
globally. Update installer message and README to use
npx @colbymchenry/codegraph init -i instead.

Updated documentation to recommend instructing Explore agents to use
CodeGraph tools (search, callers, callees, context) for faster code
exploration instead of file scanning.
Benchmark results show ~30% fewer tokens and ~25% fewer tool calls
when Explore agents leverage CodeGraph for graph-based lookups.
