* feat(resolution): close dynamic-dispatch coverage holes (callback synthesis + django ORM)
Static tree-sitter extraction misses calls whose target is computed or indirect,
so flows through callbacks, observers, and descriptors were absent from the graph.
- callback-synthesizer.ts: whole-graph pass after base resolution. Detects
registrar/dispatcher channels (field-backed observers + string-keyed
EventEmitters), correlates registration sites, and synthesizes
dispatcher->callback `calls` edges (provenance:'heuristic'). Records the
registration site (registeredAt) in edge metadata. Precision guards: named
handlers only, registrar-name match, event fan-out cap.
- frameworks/python.ts + resolution/{index,types}.ts: claimsReference hook +
django ORM resolver (_iterable_class -> ModelIterable.__iter__).
- extraction/tree-sitter.ts: extract named nested functions so inline named
handlers become linkable nodes.
trace(mutateElement, triggerRender) and trace(_fetch_all, execute_sql) now
connect; node count stable (no explosion).

* feat(mcp): self-sufficient flow output + fix explore budget regression
- Surface synthesized-edge evidence in trace, the node trail, and context call
paths: a dynamic-dispatch hop now shows "callback via onUpdate @App.tsx:3148"
with the registration site inline (and trace inlines each hop's call-site
source line) -- the exact glue agents previously Read/Grep'd to reconstruct.
- Fix non-monotonic explore output budget: the 500-5000 file tier capped
maxCharsPerFile at 2500, BELOW the <500 tier's 3800, so on god-file projects
(excalidraw's 415 KB App.tsx) one explore returned <1% of the file and forced
a Read. Raised to 6500/file, 28000 total.
- Stop explore from inviting Read: truncation/trim notes said "use Read for
more"; they now steer to another codegraph_explore and treat returned source
as already Read.
Measured on excalidraw: best-case flow answer went from 5 reads / 131s to
0 reads / 73s with ~3-4 codegraph calls.

* chore(agent-eval): coverage probes, block-read hook, and design docs
Dev-only validation harness for the dynamic-dispatch coverage work:
- probe-{trace,node,context,explore}.mjs: drive MCP tools against a built index
without a full agent run.
- block-read-hook.sh + hook-settings.json: PreToolUse experiment that denies
source Reads to measure codegraph sufficiency (forced Read-0).
- docs/design/: callback-edge-synthesis + dynamic-dispatch-coverage playbook.

* feat(resolution): bridge React boundaries — re-render + JSX child synthesis
Closes the two dynamic-dispatch hops that broke "state mutation -> on-screen
render" flows in React apps. Both are call-invisible (React-internal) but the
code between them is fully call-connected, so one synthesized edge each makes the
whole flow trace end-to-end.
- reactRenderEdges: setState(...) re-runs the component's render(). For each
class with a render method, link sibling methods calling this.setState ->
render. The setState gate keeps it to React class components.
- reactJsxChildEdges: a component that returns <Child .../> mounts Child. Link
parent -> each capitalized JSX child, resolved to a component/function/class
node (the resolution gate drops TS generics like Array<Foo>). File-oriented,
capped per parent.
- Surface both in synthEdgeNote (trace + node trail) and context call-paths.
Validated on excalidraw: trace(mutateElement, renderStaticScene) now connects in
6 hops across callback -> react-render -> jsx-child; 1 + 46 + 280 synthesized
edges, node count stable (no explosion). Partial coverage is worse than none:
react-render alone raised agent reads (revealed a hop it then drilled); adding
the jsx hop closed the flow and dropped reads to 0-1.

* docs(claude): retrieval performance contract + coverage validation methodology
Add a "Retrieval performance & dynamic-dispatch coverage" section so future
changes/PRs don't silently regress agent retrieval:
- the explore call+output budget table by repo size, with the monotonic-per-file
invariant (the bug that started this: <5000 tier's 2500 < <500 tier's 3800).
- the "partial coverage is worse than none" principle.
- the required validation methodology (small/medium/large x >=3 prompts per
language x framework; deterministic probes + agent A/B; pass bar).
- the Excalidraw worked example (before/after numbers) as the template to
replicate for every language/framework.

* docs(claude): use full n=4 measured range in Excalidraw worked example
Best run 0 Read/3 cg/76s; typical ~1 Read/~4 cg; occasional over-drill outlier.
Report the range, not a single run — run-to-run variance is large.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(mcp): steer flow questions to codegraph_trace first (tightens variance)
codegraph_trace was absent from every steering intent map — all three guidance
files routed "how does X reach Y" to context+explore, never to the trace tool.
So agents used trace only by chance; when one didn't, it floundered
reconstructing the path with search+callers (an 18-call run vs ~6 for trace-users).
Add codegraph_trace to the intent map + a "flow" common chain (trace from->to
FIRST = the whole path in one call, then ONE explore for bodies) across all three
synced files (server-instructions, instructions-template, .cursor rule).
Validated on excalidraw (hard "to the screen" Q, n=4 before/after):
- call count 3-10 -> 3-4 (over-drill outlier gone)
- duration 64-112s -> 51-74s
- trace adoption 3/4 -> 4/4; search+callers path-reconstruction -> 0
- fully-clean runs (0 Read, 0 Grep) 0/4 -> 2/4; best 3 cg / 0 / 0 / 51s

* feat(resolution): Vue SFC template coverage (events + kebab components)
The .vue extractor only parses <script>, so template usage is invisible —
handlers and kebab child components used only in <template> have no edge. Add a
vueTemplateEdges channel (scoped to the <template> block of .vue files):
- event bindings: @click="onClick" / v-on:submit="save" -> handler method/function
(skips inline arrows and $emit; resolves same-file first to avoid cross-app
mis-match in monorepos).
- kebab child components: <el-button> -> ElButton (PascalCase children like
<VPNav/> are already caught by the JSX channel via the SFC component node).
Surface vue-handler in synthEdgeNote (trace/node trail) + context call-paths.
Validated on vue repos (reindex, no node explosion):
- vue-handler edges: vitepress 15, vben 404, element-plus 603 — all precise
(code-login @submit -> handleLogin, register @submit -> handleSubmit, ...).
- callers(handleLogin) now includes the login component (was 0); each monorepo
app's login resolves to its own same-file handler.
- composition: PascalCase + kebab work; element-plus's el-/filename naming
(el-button -> button.vue) is a known library-prefix limitation.

* docs(playbook): record Vue validation in coverage matrix + limits
Vue / Nuxt row → ✅ template events + composition (vitepress S / vben M /
element-plus L); 🔬 reactive→render (vue-core Proxy runtime, deferred).
§7: Vue results + the two real limits — composable-destructure handlers
(@click="closeSidebar" from useSidebarControl, a data-flow frontier) and
prefix-convention kebab (el-button→button.vue). Agent reads dropped in every
size; strongest where handlers are local functions.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(resolution): resolve Vue composable-destructure template handlers
@click="closeSidebar" where `const { close: closeSidebar } = useSidebarControl()`
previously didn't resolve — the handler is a destructured composable return, not a
local fn node. Now: parse the SFC's `use*()` destructures into alias→{composable,
key}, and for an unresolved template handler follow alias → composable → the
returned member (`close`) defined in the composable's file. Precise-only: no
fallback to the composable itself (the component already has a static useX() call
edge), so we add an edge only when the specific returned fn is found.
Validated: vitepress Layout @click→close / @open-menu→open (in composables/
sidebar.ts); sidebar-flow agent run dropped 6→0 reads (best case). element-plus's
fallback-only matches correctly drop to 0; node counts stable; direct handlers
(vben handleLogin) unaffected.

* feat(extraction): extract function-valued properties of exported-const objects
`export const actions = { default: async () => {...} }` (SvelteKit form actions,
and general JS handler/route/reducer maps) left the arrow functions unextracted —
the walker skips object-literal functions (deliberately, to avoid inline-object
noise like `ctx.set({...})`). So an action's body (and its calls) was invisible.
Now: for an EXPORTED const whose initializer is an object literal, extract each
function-valued property (arrow / function expression) as a function named by its
key and walk its body. extractFunction gains a nameOverride so ONLY this explicit
path names pair-arrows — inline-object arrows reached by the general walker still
fall through to the <anonymous> skip, so no noise returns. JS/TS-gated.
Validated: fixtures extract the actions + walk bodies (default→helper, default→
api.post resolve); SvelteKit detection doesn't break it. Blast radius tiny:
excalidraw +1 node, Python (django) +0, Vue repos +0, realworld +11 (the actions).
Known residual: a `$lib`-alias namespace-member call (`api.post`) from an extracted
action node doesn't resolve even though the same alias resolves for `load` — a
deeper resolver interaction, separate from this extraction change. Local/relative
calls from actions connect fine.

* docs(playbook): record Svelte validation (already well-covered) + actions fix
Svelte/SvelteKit row → already strong (template calls/composition/namespace/load);
+ exported-const object-of-functions extraction. Lesson: measure before assuming
a hole — modern Svelte barely uses on:click={fn}; Svelte needed far less than Vue.

* feat(resolution): connect Express inline arrow route handlers to their services
The Express resolver created route nodes but linked handlers via a single regex
whose `[^)]+` broke on inline arrows — so `router.post('/x', async (req,res) =>
{...})` (the dominant modern pattern) connected to NOTHING, and the anonymous
handler's body (the actual request→service flow) was lost. The whole inline-handler
API was unreachable: e.g. realworld's `POST /users/login` route → 0 edges.
Now: match the route head, span the full call with a string-aware balanced-paren
scan, and for an inline arrow handler extract its body's calls (string-aware brace
scan) and attribute them to the route node as `calls` edges. A RESERVED denylist
drops res/req/builtin methods (json, next, status, ...) to keep only business calls.
Named-handler routes keep the existing reference behavior.
Validated: realworld POST /users/login → login (auth.service); 19 precise
route→service edges (was 0) — POST /articles→createArticle, .../favorite→
favoriteArticle, etc., no json/next noise. ghost +65 inline-handler edges. No node
explosion (ghost 40767, parse 3394 unchanged). Framework-scoped: zero blast radius
off Express.

* docs(playbook): record Express validation (inline-handler fix)
Express/Koa row → resolver already handled named handlers; the real hole was
inline arrow route handlers (router.post('/x', async (req,res)=>{...})) — fixed:
route→service body calls (realworld 19 / ghost 65 edges, no explosion). Agent A/B
muddied by repo size (realworld tiny) / complexity (ghost layered API). Lesson
inverse of Svelte: Express's dominant pattern WAS the uncovered one.

* docs(playbook): record NestJS validation (already well-covered)
NestJS row → resolver handles @decorator routes; DI controller→service
(this.svc.method) resolves correctly at scale (immich: addUsersToAlbum→addUsers,
etc.). Agent A/B: codegraph eliminated Grep (0 vs 3). No dynamic-dispatch hole.
Surfaced a general hygiene gap (not NestJS): committed dist/ build output gets
indexed (no default build-dir ignore) — narrow (real apps gitignore dist/),
deferred as a core-indexer follow-up.

* feat(resolution): Rails RESTful resources routing → controller#action
The rails resolver only saw explicit `get '/x' => 'c#a'` routes, so apps using
the dominant `resources :articles` / `resource :user` RESTful routing had ZERO
route nodes (realworld + spree: 0 routes despite full routes.rb files). The whole
request→controller flow was disconnected.
Fix (frameworks/ruby.ts):
- extract: expand `resources`/`resource` into their REST actions (only/except
filters; pluralize the singular `resource :user` → users_controller), emit a
precise `controller#action` ref per action. Explicit routes now also reference
`controller#action` instead of a bare ambiguous `action`.
- resolve: new `controller#action` pattern → the action method in
<ctrl>_controller.rb (file convention + controller-class fallback).
- claimsReference: claim `controller#action` refs so resolveOne's pre-filter
doesn't drop them before resolve() runs (same hook the django ORM work needed —
these refs name no declared symbol).
Validated: realworld 0→16, forem 0→635 precise route→action edges (GET /articles→
index, resource :user→users#show, etc.), pluralization correct, no node explosion
(route nodes proportional to resources). Agent A/B (forem, large): with codegraph
1-4 reads / 0 grep / 47-53s vs without 4-5 reads / 2-3 grep / 66-85s. Framework-
scoped (zero blast radius off Rails). Residuals: Rails Engine routing (spree
mounts an engine), ActiveRecord dynamic finders (metaprogramming frontier).

* feat(resolution): Spring bare + class-prefixed route mappings → controller method
The Spring resolver required a string path in the mapping regex, so BARE method
mappings (`@PostMapping` with the path on the class-level `@RequestMapping`) were
missed — the dominant multi-method-controller pattern. realworld's two-action
ArticleFavoriteApi only linked one method; halo had 28 routes for 2444 files.
Fix (frameworks/java.ts):
- Treat class-level `@RequestMapping` as a PREFIX (not a bogus route) and join it
onto each method's path.
- Match verb-specific mappings (@GetMapping/@PostMapping/...) BARE or with a path.
- Also handle method-level `@RequestMapping(value=..., method=RequestMethod.X)`
(older style) — restored after an initial cut dropped it (mall regressed 292→1;
caught by the regression check).
Validated: realworld 13→19, mall 246 (all precise, class prefix joined:
GET /subject/listAll→listAll, POST /articles/{slug}/favorite→favoriteArticle +
DELETE→unfavoriteArticle), no node explosion. DI controller→service resolves
(article→findBySlug, updateArticle→canWriteArticle). Agent A/B (mall cart flow):
with codegraph 0 reads/0 grep vs without 2/2. Residuals: halo's complex custom
patterns (9/29 resolve); Spring Data JPA derived queries (metaprogramming frontier).

* feat(resolution): Django DRF router.register → ViewSet
Django's ORM (_iterable_class, prior work) and URL routing (path/url/as_view→view)
were already covered. The remaining hole: DRF `router.register(r'articles',
ArticleViewSet)` — the core CRUD endpoints — wasn't extracted (only path()/url()),
so a DRF API's main resources connected to nothing (realworld's ArticleViewSet:
0 callers).
Fix (frameworks/python.ts): match `.register(r'prefix', XViewSet)` → route→ViewSet
class. The STRING first arg distinguishes DRF router.register from
`admin.site.register(Model, Admin)` (model class first arg); View/ViewSet suffix
keeps it to viewsets. The ViewSet class resolves via the existing View/ViewSet
pattern.
Validated: realworld VIEWSET /articles → ArticleViewSet (was 0). Narrow in corpus
(realworld 1 router; wagtail=path, saleor=GraphQL) but real for DRF-router APIs.
Agent A/B (wagtail Page flow, medium): with codegraph 4-7 reads / 1-4 grep / 58-81s
vs without 7-9 reads / 6 grep / 82-86s. No regression (wagtail/saleor route counts
unchanged — purely additive). Residuals: signals, DRF inherited viewset actions,
GraphQL resolvers.

* feat(resolution): Laravel route → precise Controller@method (not bare action)
extractLaravelHandler discarded the controller: `Route::get([UserController::class,
'index'])` and `'UserController@index'` both emitted a BARE `index` ref. With the
route in routes/api.php (not the controller file), name-matching mis-resolved every
common action to the WRONG controller — realworld's GET user → ArticleController.index
(should be UserController), GET articles/feed → ArticleController (should be
FeedController), etc. The routes existed but pointed at the wrong handler.
Fix (frameworks/laravel.ts): emit precise `Controller@method` (array + string
syntax, namespace-stripped) and `claimsReference` it so resolveOne's pre-filter
doesn't drop it before Pattern-4 resolveControllerMethod runs (the recurring hook,
also needed by django ORM + Rails routing).
Validated: realworld all routes now resolve to the correct controller; bookstack
267/332 precise (GET pages → PageApiController.list, array syntax). No node
explosion. Agent A/B (bookstack page-view, large): with codegraph 2-3 reads / 1-2
grep / 51-60s vs without 4-6 / 3-5 / 60-74s. Residuals: firefly's fluent
->uses()/['uses'=>...] handler format (3/568 resolve), Eloquent dynamic finders.

* feat(resolution): Gin/chi routes on group vars (any receiver, not just r/router)
The route regex matched only `(router|r|mux|app|e).METHOD(...)`, but real Gin/chi
apps route on GROUP variables — `v1.GET`, `PublicGroup.GET`, `userRouter.POST` —
so group-routed apps connected almost nothing: gin-vue-admin had 4 routes for 625
files. Broaden the receiver to ANY identifier; the verb + string-path + handler-arg
gates keep it route-specific (e.g. `http.Get(url)` has no handler arg, so it's
excluded).
Validated: gin-vue-admin 4→259 routes, 257 resolve precisely (POST createInfo→
CreateInfo, GET getInfoList→GetInfoList); realworld stable 24→25 (no regression);
no garbage (257/259 resolve, not false positives), node count proportional. gitness
(chi, custom handlers) is a residual (26/321). Inline `func(c *gin.Context){...}`
handlers still lose their body (anonymous, like Express was) — separate residual.

cleanest backend win yet. Residuals: inline func handlers, gitness chi custom.

* feat(resolution): ASP.NET feature-folder detection + bare attribute routes
Two holes left ASP.NET apps disconnected:
1. detect() only fired on a /Controllers/ dir, root Program.cs/Startup.cs, or a
.csproj (which often isn't in the indexed source set). Feature-folder apps
(realworld: Features/*/FooController.cs, subdir Program.cs) were never detected
→ 0 routes despite a full set of controllers. Broaden: scan Controller/Program/
Startup .cs source for ASP.NET signatures ([ApiController]/[Route]/[Http*],
ControllerBase, MapControllers, WebApplication, Microsoft.AspNetCore).
2. The attribute regex required a string path, so BARE [HttpGet] (route on the
class [Route("[controller]")]) was missed — eShopOnWeb was 24 bare / 2 string.
Match bare-or-with-path + join the class [Route] prefix (like the Spring fix).
No claimsReference needed: ASP.NET attribute routes are co-located IN the controller
with the action, so the bare method-name ref resolves same-file.
Validated: realworld 0→19 routes (all precise: GET /articles→Get, POST /articles→
Create, class prefix joined), eShopOnWeb 9→33. Route→action correct + co-located.

* feat(resolution): Flask/FastAPI route holes + Python builtin-name handler guard
Three fixes that connect the request→route→handler flow for Flask and
FastAPI. Validated S/L: fastapi-realworld 12→20, flask-microblog 6→27,
Netflix dispatch 290/290 (100%), redash decorator routes 6/6; canonical
flows trace end-to-end (login→get_user_by_email, create_user→from_dict).
- Flask: the route regex required `def` immediately after `@x.route(...)`,
so an intervening decorator (@login_required, @cache.cached) or stacked
@x.route lines (one view bound to several URLs) dropped the route.
Switch to the findHandler scan (match the decorator, then find the next
def) like FastAPI — skips intervening decorators.
- FastAPI: the path regex `[^'"]+` rejected the empty path `@router.get("")`
(router/prefix-root routes, frequently multi-line). Allow empty path +
guard the route name against a trailing space.
- Python builtin-name guard (src/resolution/index.ts): a handler named
after a Python builtin method (index/get/update/count…) was filtered by
isBuiltInOrExternal and lost its route→handler edge. Mirror the
dotted-method branch's knownNames guard onto the bare branch — a bare
name a declared symbol owns is a real target, not a builtin call.
+2 legit edges on realworld, 0 change on the django control (precision held).
Tests: new Flask (intervening/stacked decorator) and FastAPI (empty-path,
multi-line) extractor cases + a Flask end-to-end integration test (a view
named `index` behind @login_required). Also corrects 6 pre-existing stale
Laravel/Rails route-ref assertions surfaced by the suite — they expected
the old bare action name, but the resolvers now emit precise
controller@action / controller#action (from earlier precision commits).
Full suite green (781 passed).

* feat(resolution): Drupal route-handler resolution (claimsReference, single-colon controllers, contrib detection)
The *.routing.yml extractor and _controller/_form resolver existed but two
gaps left most routes unlinked. Validated S/M/L: admin_toolbar 0→14 (14/14),
webform 144/208, drupal-core 536→731/836 (87%); canonical flow traverses
(getAnnouncements ← /admin/announcements_feed); node count unchanged.
- claimsReference: Drupal handler refs are FQCNs (\Drupal\…\Class::method),
bare form classes (\…\SettingsForm), or single-colon controller-services
(\…\Controller:method). Only the ::method shape survived resolveOne's
pre-filter (its member is a known method name); the bare-FQCN forms and
single-colon controllers were dropped before resolve() ran. Claim FQCN /
Class:method / hook_* refs (same pattern as Rails controller#action).
- Single-colon controller match: broaden the controller regex from :: to
:{1,2} and tighten the _form branch to !name.includes(':').
- Detection: detect() only checked composer `require` for a drupal/* dep, but
a contrib module often has an empty require and is identified only by
"name":"drupal/<m>" + "type":"drupal-module" (admin_toolbar → 0 routes).
Broaden to composer name/type + a *.info.yml fallback.
Remaining unresolved is the entity-annotation handler frontier
(_entity_form: type.op) and OOP #[Hook] attributes (Drupal 11 moved ~all
procedural hooks to attribute methods — out of scope here). Tests: contrib
detection, *.info.yml fallback, claimsReference, single-colon controller.

* feat(resolution): Axum chained methods + namespaced handlers
The Axum route extractor used a flat regex that captured only the first
method(handler) of a .route() call and only a bare \w+ handler, so two
dominant Axum idioms broke:
- method chains: .route("/user", get(get_current_user).put(update_user))
emitted no node for the .put arm — half the API was missing.
- namespaced handlers: get(listing::feed_articles) captured `listing`
(the module), so the route resolved to nothing.
Rewrite with a balanced-paren scan of each .route(...) call, a route node
per chained method, and last-::-segment handler names. realworld-axum
12→19 routes, 19/19 resolved (every chained PUT/DELETE/POST now present,
feed_articles resolves). Rocket needed nothing (550/556, 99%, attribute
macros); crates.io confirms namespaced axum handlers resolve.
Residual frontier: actix runtime routing web::get().to(handler) (the
dominant actix style, unextracted; attribute macros 35/51). Fix is
Axum-scoped — the attribute/actix/Rocket path is untouched. Tests: chained
methods + multi-line namespaced handler. Full suite green (789 passed).

+ namespaced-handler fix (realworld-axum 12→19, 19/19), Rocket already 99%,
crates.io (utoipa routes! macro frontier + SvelteKit frontend routes), the
update-user A/B, and the actix runtime-routing frontier.

* feat(resolution): Vapor grouped/RouteCollection routing (was 0 routes on real apps)
The Vapor extractor only matched (app|router|routes).METHOD("path", use:
handler), but real Vapor apps route on a grouped builder inside
RouteCollection.boot(routes:): `let todos = routes.grouped("todos");
todos.get(use: index)` — any var receiver, no path arg (the path is the
group prefix). Every real app tested extracted 0 routes (template,
SteamPress, SwiftPackageIndex-Server, penny-bot, Feather).
Rewrite the extractor:
- any receiver (\w+), not just app/router/routes;
- optional path segments that may be non-string (User.parameter, :id, a
path constant) — the `use:` keyword discriminates a route from
Environment.get("X") / req.parameters.get("X");
- a group-prefix map from `let X = Y.grouped("a")` and
`Y.group("a") { X in }` so a grouped/nested route gets its full path
(todo.delete(use: delete) -> DELETE /todos/:todoID).
Result: vapor-template 0→3 (3/3, nested path exact), SteamPress 0→27
(27/27), SwiftPackageIndex-Server 0→14 (14/14 handler resolution).
Canonical flow traverses (createPostHandler <- GET /createPost ->
createPostView). Route names now carry a leading slash (GET /users),
consistent with the other frameworks.
Frontier: typed-route enums (SPI's SiteURL.x.pathComponents — handler
resolves, path label only) and closure handlers (app.get("x"){ } —
anonymous). Tests: grouped RouteCollection, self.handler + non-string
segments, use:-discriminator. Full suite green (792 passed).

* docs(playbook): record Vapor validation (grouped RouteCollection routing)
Update the Swift/Vapor matrix row ⬜→✅ and add a §7 note: the extractor was
dead on real apps (0 routes everywhere); rewrote for any receiver, optional
non-string paths, .grouped/.group{} prefix tracking, and the use:
discriminator. S/M/L all 100% handler resolution (template 0→3, SteamPress
0→27, SPI 0→14), the create-post A/B (0 read/0 grep with vs 1–4 read
without), and frontiers (typed-route enums, closure handlers).

* feat(resolution): React Router <Route> JSX route extraction
react.ts extracted components/hooks and Next.js file routes but returned
references: [], so React Router <Route> declarations produced no route
nodes or route→component edges. Add <Route> JSX extraction: scan a window
after each <Route (so the nested > in element={<Comp/>} doesn't truncate
the match), pull path="…" + component={C} (v5) or element={<C/>} (v6) in
any attribute order, emit a route node + component reference (resolved by
the existing PascalCase resolveComponent). The <Routes> container is
excluded via the \b boundary.
react-realworld 0→10 routes, 10/10 resolved (/login→Login,
/editor/:slug→Editor, /@:username→Profile). No regression on excalidraw
(9,290 nodes, 46 react-render synth edges intact, 0 false routes). Tests:
v5 component=, v6 element=, <Routes>-container guard. Suite green (794).
Frontier: object data-router createBrowserRouter([{path,element}]) (modern
v6) is object-based not JSX — not covered.

* feat(resolution): actix-web builder-API routing (web::resource / .to(handler))
Actix's attribute macros were covered, but the dominant actix style is the
builder API — web::resource("/path").route(web::get().to(handler)),
web::resource("/").to(handler) (all methods), and App .route("/path",
web::get().to(handler)). The handler is in .to(handler), not get(handler),
so the Axum .route scan extracted nothing — actix-examples had 80
web::resource calls all unlinked.
Add an actix block: scan each web::resource("/path") (bounding its method
chain at the next resource) for web::METHOD().to(h) pairs, fall back to a
direct .to(h) (method ANY), plus the App-level .route("/x",
web::METHOD().to(h)) form. actix-examples 51→128 routes, 35→112 resolved
(GET /user/{name}→with_param, POST /user→add_user). No regression on Axum
(realworld-axum still 19/19). Tests: resource+route, resource direct .to,
App-level route. Suite green (797).
Frontier: web::scope("/api") prefixes not prepended; anonymous .to(|req|…)
closures have no named target.

* feat(extraction): Flutter setState→build synthesis + Dart method body ranges
Two changes that connect Flutter's reactive dispatch:
- Dart method ranges (foundational): Dart models a method body as a SIBLING
of the method_signature node, so every Dart method node had endLine ==
startLine (signature only) — body-level analysis (callees, context slices,
the synthesizer's body scan) saw only `void f() {`. Extend endLine to the
resolved body in the shared createNode, guarded to only ever extend
(child-body grammars are a no-op; controls excalidraw 9,290 / django 302
unchanged).
- Flutter setState→build synthesizer channel (the Dart analog of react-render):
for each Dart class with a `build` method, link sibling methods whose body
calls setState( → build. setState re-runs build (Flutter-internal, no static
edge), so "tap → handler → setState → rebuilt UI" dead-ended at setState.
counter initState→build, books build→BookDetail/BookForm. Widget composition
needs no synthesis — Dart widgets are explicit constructor calls, already
static (compass_app build→ErrorIndicator/HomeButton). Tests: Dart method
spans its body; Flutter handler→build synthesis end-to-end. Suite green (798).
Frontier: MVVM Command/ChangeNotifier dispatch (no setState) + Navigator.push
route-as-widget navigation.

* feat(resolution): Spring Boot Kotlin routing (.kt + fun handlers)
Kotlin had zero framework coverage — no resolver listed kotlin, and the
Spring resolver was languages:['java'] with a .java-only extract gate and a
Java-syntax handler regex (public X name()). Spring Boot Kotlin apps (same
@GetMapping/@RestController annotations, .kt files) extracted 0 routes.
Extend the Spring resolver: languages ['java','kotlin'], accept .kt, and add
a Kotlin `fun name(` alternative to the handler-method regex (Kotlin has no
access modifier; the return type follows the name). Also allow Kotlin class
modifiers (open/data/sealed) in the class @RequestMapping-prefix detection,
and tag route/ref language per file.
spring-petclinic-kotlin 0→18 routes, 18/18 resolved; class @RequestMapping
prefixes join, stacked annotations skipped, DI controller→repo resolves
(showOwner ← GET /owners/{ownerId} → OwnerRepository.findById). Java Spring
unchanged (realworld 19/19 — the Kotlin fun and Java public-X alternatives
are disjoint per language). Jetpack Compose composition already works
(@Composable→child are plain function calls). Tests: Kotlin @GetMapping+fun,
class-prefix + stacked annotation. Suite green (800).
Frontier: Ktor inline-lambda routing, Compose recomposition, coroutines/Flow.

* docs(playbook): record Lua/Luau validation (module dispatch already covered)
Measure-first: Neovim/Roblox dispatch is module-heavy (require + cross-file
mod.fn calls), already resolved by general import+name resolution
(telescope.nvim 220 imports + 335 cross-file calls; traces end-to-end). The
matrix's assumed "callback synthesizer" hole isn't real — event-callback
registration (keymap/autocmd/:Connect) is predominantly inline anonymous
closures (corpus ~12 inline vs ~2 named), too rare to synthesize. A/B: 0
read/0 grep with codegraph vs 1 read without. No code change; validated.

* feat(resolution): Play Framework conf/routes → controller routing (Scala/Java)
Play declares routes in an extensionless conf/routes file (GET /computers
controllers.Application.list(p: Int ?= 0)) the file walk never indexed
(isSourceFile requires an extension), so Play apps had 0 route nodes.
- grammars.ts: add isPlayRoutesFile (conf/routes + *.routes), opt it into
isSourceFile, and map it to the no-grammar (yaml-style) path in
detectLanguage so the framework resolver extracts it. Narrow match — only
ADDS Play routes files, never affects other indexing.
- play.ts: a Play resolver — detect (build.sbt/conf), extract (parse each
METHOD /path Controller.action(args) line, drop package + args), resolve
(Controller.action → the action method in that controller class),
claimsReference for the dotted Controller.action handler.
computer-database 0→8 routes, 7/8 resolved (the 1 unresolved is
controllers.Assets.versioned — Play's framework controller, external);
starter 0→4 (3/4). Flow connects request→route→controller→DAO. No-regression
(excalidraw 9,290 / suite unchanged). Tests: routes parse + `->` include
skipped, conf/routes file detection.
Frontier: SIRD programmatic routers (-> include + case GET(p"/x")) + Akka
actor message→handler.

* feat(extraction): C++ inheritance (base_class_clause) + virtual-override synthesis
C/C++ direct dispatch already resolves well (redis 29k / leveldb 1.4k
cross-file calls). Two changes close the C++ virtual-dispatch gap:
- extractInheritance handled base_clause (PHP) but not C++'s
base_class_clause, so C++ `extends` edges were missing/partial. Add the
C++ branch (emit an extends ref per base type, skipping access
specifiers) — leveldb extends 219→298.
- cpp-override synthesizer channel (the C++ analog of react-render): for
each extends edge, link each base method → the subclass override of the
same name, so trace/callees from a virtual/interface method reach the
implementation. Gated to C++, capped per class. leveldb 12 precise edges
(Iterator::Next/Seek/Prev → MergingIterator), 0 on C (redis) and TS
(excalidraw). Test: base virtual → subclass override bridge.
Frontier: C callback structs (cmd->proc() → 422-way fan-out, too noisy)
and C++ pure-virtual base methods (declarations aren't nodes, so those
overrides can't bridge). Suite green (804).

* feat(resolution): React Router object data-router + Next.js route precision
- Object data-router (v6.4+): createBrowserRouter([{ path, element: <Comp/> }])
/ { path, Component: Comp } — extract route + component (gated to files using
the data-router API; requires a component so a stray `path:` field isn't a route).
- Next.js precision: filePathToRoute treated config files (next.config.mjs,
vite.config.ts) and a `nextjs-pages/` dir (substring of "pages/") as routes.
Require a real page extension (.tsx/.ts/.jsx/.js), exclude *.config.* and
_app/_document, and match pages/ + app/ as path SEGMENTS. bulletproof-react
4 bogus config "routes" → 0.
Frontier: lazy data-router routes (path: paths.x.path + lazy: () => import())
use variable paths + lazily-imported modules — no literal path/named component.
Tests: object-router literal form, config/nextjs-pages exclusion. Suite 806.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(resolution): Flask-RESTful add_resource + tuple methods + broader detection
Three Flask gaps closed (redash Flask-RESTful 6→77 py routes; flask-realworld 0→19):
- Flask-RESTful: api.add_resource(ResourceClass, '/path') (+ redash's
add_org_resource) now extracts a route per path referencing the Resource
class, whose get/post verb methods resolve as the handlers.
- Tuple methods: @x.route('/p', methods=('POST',)) — the method regex only
accepted a list [...]; now accepts a tuple (...) too, so POST/DELETE routes
aren't mislabeled GET.
- Detection: detect() only checked root app.py for the literal Flask(__name__);
broadened to requirements/pyproject/Pipfile/setup.py + any entrypoint file
(root or subdir, e.g. conduit/app.py) that imports flask and instantiates
Flask(...). flask-realworld (subdir app-factory) 0→19; django not falsely
detected.
Tests: tuple methods, add_resource. Suite green (808).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(playbook): record frontier pass; test(go): gorilla/mux subrouter coverage
Frontier triage after the main sweep — tractable partials closed (React object
data-router, Next.js false-positive fix, Flask-RESTful add_resource, Flask
tuple methods + detection, gorilla/mux confirmed), and the genuinely
hard/low-precision ones (C callback fan-out, metaprogramming finders, reactive
runtimes, Akka, anonymous closures, lazy data-router, C++ pure-virtual) left
documented with rationale. Adds a gorilla/mux subrouter-var HandleFunc test
(confirms the any-receiver handling already covers it).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(benchmarks): A/B with/without codegraph across every language (S/M/L)
37-cell matrix (every flow-relevant language × small/medium/large indexed
repos): a headless agent answers one canonical flow question per repo, with the
codegraph MCP vs without any MCP. Fresh re-index per cell so the with-arm
reflects current resolvers.
Result: 75% fewer file reads with codegraph (40 vs 158 across cells), ~70%
fewer greps, never more reads in any cell. Biggest wins on medium/large
backends (excalidraw 0R vs 9R, spring-halo 0R vs 9R+8 Bash, jellyfin 4R vs 13R+
21 Bash + a spawned sub-agent); tie zone on tiny repos where the flow fits in
1-2 files.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(mcp): self-sufficient codegraph_trace + CODEGRAPH_MCP_TOOLS allowlist
codegraph_trace now returns a complete flow dossier in one call: each hop with its full body inlined (not just the call-site line), plus the destination's own outgoing calls — the last mile agents otherwise explore/Read to get. Validated by A/B (arm I, 6 repos x 2): >= baseline on reads/turns/cost with no wall-clock regression, because one richer trace call displaces the explore+node+Read follow-ups. Sufficiency, not steering: complete context is what stops further investigation.
Also adds CODEGRAPH_MCP_TOOLS, an optional comma-separated allowlist that trims the exposed MCP tool surface (inert when unset); used to run the tool-ablation experiment cleanly, and useful for constraining an agent to a minimal surface.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(benchmarks): call-sequence + tool-ablation analysis; agent-eval arms harness
Records why codegraph read savings (-75%) under-convert to wall-clock (-16%): the bottleneck is round-trips + the synthesis turn, not reads. Ablation (arms A-I) shows explore is 68% of payload but load-bearing, trace is path-scoped but under-adopted, instruction/description steering cannot match an append-prompt's salience (and regresses), and the shippable win is making the trace output sufficient (arm I). Adds harness: seq-matrix, run-arms/arms-*, parse-arms.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(mcp): line-number codegraph_node + codegraph_trace source output
node's code block and trace's inlined hop/destination bodies now carry cat -n line numbers (reusing numberSourceLines, matching codegraph_explore and Read), so the agent can cite or edit exact lines without re-Reading the file just to get them. Consistency across the code-returning tools + edit-workflow sufficiency.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(resolution): Java/Kotlin interface & abstract dispatch synthesis
A call through an injected interface (Spring @Autowired svc.list()) or an abstract base dead-ended at the interface method — no static edge to the implementation — so request->service->impl flows broke at the DI boundary. Adds interfaceOverrideEdges: for each class implementing an interface (or extending an abstract base), synthesize interface/base-method -> same-name override 'calls' edges (JVM-gated, capped per class, overload-aware), with an 'interface-impl' trace label. trace + callees now follow the flow into the implementation.
Validated on spring-mall: 310 synth edges, node count unchanged (edges only); trace(PmsProductController.getList, PmsProductServiceImpl.list) connects in 3 hops (controller -> service interface -> impl) where it previously dead-ended at the interface.

* docs(playbook): record Java/Kotlin interface-DI synthesizer (probe-validated; agent A/B adoption-gated)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(mcp): codegraph_explore surfaces the execution flow from its named symbols
Agents call explore far more than trace and pass a bag of symbol names that spans the flow they're after. explore now resolves those names and surfaces the longest call path AMONG them — riding synthesized dynamic-dispatch edges (callback/react-render/jsx/interface-impl) — leading the output with it, so a flow question answered via explore gets the trace-quality path without switching tools.
Precision: ambiguous tokens disambiguated by CO-NAMING (keep candidates whose qualifiedName SEGMENT matches another named token, so 'list' resolves to PmsProductServiceImpl::list not OmsOrderService::list); BFS anchored at named symbols on both ends with <=1 consecutive unnamed bridge (crosses a missing intermediate, never wanders a god-function's fan-out). Validated by probe: spring-mall getList->service-interface->impl (3 hops); excalidraw mutateElement->triggerUpdate->[callback]->triggerRender->[react-render]->render->[jsx]->StaticCanvas (full re-render chain). No flow section on fuzzy queries (safe). Suite green.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(mcp): explore-flow resolves qualified Class.method query tokens
The agent often passes fully-qualified names to explore (PostEndpoint.publishPost, PmsProductServiceImpl.list) — its most precise input. The tokenizer's file-extension strip mangled Class.method into Class (treating .method as an extension), then the identifier filter dropped anything with a dot, throwing the method away. Now strips only REAL file extensions and keeps qualified tokens, which findAllSymbols resolves exactly; disambiguates ambiguous SIMPLE names by whether their container class is also named (segment match). Validated: 'PmsProductController.getList PmsProductServiceImpl.list' now surfaces getList->interface->impl. (spring-halo's publish flow stays absent — it's reactive/reconciler dispatch with no static edges, a coverage frontier, not an explore-flow gap.)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(claude): record the 'adapt the tool to the agent' retrieval principle
The lever that decides whether a retrieval change lands: make a tool the agent already calls do more with the input it already gives; changes that need the agent to behave differently (different tool, query, examples) hit codegraph's low-salience channels and don't land. Captures the validated evidence (sufficiency + explore-flow pass; steering + new-tools + context-fuzzy-flow fail) and points coverage as the remaining lever.

* docs: correct 'cost stays flat' → neutral-to-lower (excalidraw with/without A/B)
Fresh with-vs-without A/B on excalidraw (current build, n=3): 3x faster (49s vs 145s), 15x fewer tool calls, ~0 vs 23 reads, and -40% cost ($0.41 vs $0.68). Cost is neutral-to-lower, not flat — compact codegraph answers cache across turns while the without-arm's read/grep thrash is fresh, poorly-cacheable input. Recorded in call-sequence-analysis.md; corrected the CLAUDE.md optimization-target note (still: don't optimize for cost; target wall-clock + tool-call count).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(benchmarks): current-build A/B on all 7 README repos + fix token-measurement bug
Re-ran the README benchmark on the current build (7 repos reindexed, median of 4): avg 35% cost / 57% tokens / 46% time / 71% tool calls saved — reproduces the published README (35/59/49/70), no regression. Adds bench-readme.sh + parse-bench-readme.mjs harness.
Fixes a token-measurement bug: result.usage is last-turn-only in current Claude Code; must sum per-turn assistant usage for cumulative tokens. Corrects the earlier excalidraw note (its '-34% tokens' was off this bug; real ~90%) and the cost MECHANISM (volume/fewer-turns, not cache-ability — the without-arm's huge token volume is mostly cheap cache-reads, so token savings 57% > cost savings 35%). Cost/time were always correct.

* docs: finalize 0.9.4 — consolidate CHANGELOG + re-validate README benchmark
Folds the framework sweep + retrieval work into [0.9.4] (2026-05-24). README benchmark table refreshed with current-build medians (avg 35% cost / 57% tokens / 46% time / 71% tool calls) + a v0.9.4 re-validation note.

|
|
|
## Get Started
|
|
|
|
**No Node.js required** — one command grabs the right build for your OS:
|
|
|
|
```bash
|
|
# macOS / Linux
|
|
curl -fsSL https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.sh | sh
|
|
|
|
# Windows (PowerShell)
|
|
irm https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.ps1 | iex
|
|
```
|
|
|
|
Already have Node? Use npm instead (works on any version):
|
|
|
|
```bash
|
|
npx @colbymchenry/codegraph # zero-install, or:
|
|
npm i -g @colbymchenry/codegraph
|
|
```
|
|
|
|
<sub>CodeGraph bundles its own runtime — nothing to compile, no native build, works the same everywhere. The interactive installer auto-configures your agent(s) — Claude Code, Cursor, Codex CLI, opencode, Hermes Agent.</sub>
|
|
|
|
### Initialize Projects
|
|
|
|
```bash
|
|
cd your-project
|
|
codegraph init -i
|
|
```
|
|
|
|
<div align="center">
|
|
|
|

|
|
|
|
</div>
|
|
|
|
### Uninstall
|
|
|
|
Changed your mind? One command removes CodeGraph from every agent it configured:
|
|
|
|
```bash
|
|
codegraph uninstall
|
|
```
|
|
|
|
<sub>Reverses the installer — strips CodeGraph's MCP server config, instructions, and permissions from each configured agent. Your project indexes (`.codegraph/`) are left untouched; remove those per-project with `codegraph uninit`. Use `--target` to remove from specific agents, or `--yes` to run non-interactively.</sub>
|
|
|
|
---
|
|
|
|
## Why CodeGraph?
|
|
|
|
When Claude Code explores a codebase, it spawns **Explore agents** that scan files with grep, glob, and Read — consuming tokens on every tool call.
|
|
|
|
**CodeGraph gives those agents a pre-indexed knowledge graph** — symbol relationships, call graphs, and code structure. Agents query the graph instantly instead of scanning files.
|
|
|
|
### Benchmark Results
|
|
|
|
Tested across **7 real-world open-source codebases** spanning 7 languages, comparing an agent (Claude Code, headless) answering one architecture question **with** and **without** CodeGraph. Each cell is the savings at the **median of 4 runs per arm**. _Re-validated on **v0.9.4** (2026-05-24)._

The gains scale with codebase size: on large repos the agent answers from the index in a handful of calls with **zero file reads**, while the no-CodeGraph agent fans out across grep/find/Read (and the sub-agents it spawns). On a small repo like Gin (~150 files) native search is already cheap, so the margin narrows.

**Methodology.** Each arm is `claude -p` (Claude Opus 4.7) run headlessly against the repo with `--strict-mcp-config`: **WITH** = CodeGraph's MCP server enabled, **WITHOUT** = an empty MCP config. Built-in Read/Grep/Bash stay available to both. Same question per repo, **4 runs per arm, median reported**. Cost = the run's `total_cost_usd`; Tokens = total tokens processed (input incl. cached + output); Time = wall-clock; Tool calls = every tool invocation, including those inside any sub-agents the model spawns. Repos cloned at `--depth 1` and indexed by the same CodeGraph build that served them. Re-validated on codegraph **v0.9.4** (2026-05-24); per-repo numbers move run-to-run with how hard the without-arm thrashes (the median-of-4 smooths it, but tails remain — e.g. Tokio's without-arm hit $2.41/3m one batch).

**Queries:**

**Raw medians — WITH → WITHOUT:**

**Why CodeGraph wins:** with the index available, the agent answers directly — `codegraph_context` to map the area, then one `codegraph_explore` for the relevant source — and stops, usually with zero file reads. Without it, the agent (and the Explore sub-agents it spawns) spends most of its budget on discovery (find/ls/grep) before reading the right code. CodeGraph only helps when queried *directly*, so its instructions steer agents to answer directly rather than delegate exploration to file-reading sub-agents — otherwise a sub-agent reads files regardless and CodeGraph becomes overhead.

|
|
|
|
---
|
|
|
|
## Framework-aware Routes
|
|
|
|
CodeGraph detects web-framework routing files and emits `route` nodes linked by `references` edges to their handler classes or functions. Querying callers of a view/controller now surfaces the URL pattern that binds it.
|
|
|
|
| Framework | Shapes recognized |
|
|
|---|---|
|
|
| **Django** | `path()`, `re_path()`, `url()`, `include()` in `urls.py` (CBV `.as_view()`, dotted paths) |
|
|
| **Flask** | `@app.route('/path', methods=[...])`, blueprint routes |
|
|
| **FastAPI** | `@app.get(...)`, `@router.post(...)`, all standard methods |
|
|
| **Express** | `app.get(...)`, `router.post(...)` with middleware chains |
|
|
| **NestJS** | `@Controller` + `@Get/@Post/...`, GraphQL `@Resolver` + `@Query/@Mutation`, `@MessagePattern`/`@EventPattern`, `@SubscribeMessage` |
|
|
| **Laravel** | `Route::get()`, `Route::resource()`, `Controller@action`, tuple syntax |
|
|
| **Drupal** | `*.routing.yml` routes (`_controller`, `_form`, entity handlers); `hook_*` implementations in `.module`/`.theme`/`.install`/`.inc` |
|
|
| **Rails** | `get '/x', to: 'users#index'`, hash-rocket `=>` syntax |
|
|
| **Spring** | `@GetMapping`, `@PostMapping`, `@RequestMapping` on methods |
|
|
| **Gin / chi / gorilla / mux** | `r.GET(...)`, `router.HandleFunc(...)` |
|
|
| **Axum / actix / Rocket** | `.route("/x", get(handler))` |
|
|
| **ASP.NET** | `[HttpGet("/x")]` attributes on action methods |
|
|
| **Vapor** | `app.get("x", use: handler)` |
|
|
| **React Router** / **SvelteKit** | Route component nodes |

|
## Quick Start
|
|
|
|
### 1. Run the Installer
|
|
|
|
```bash
|
|
npx @colbymchenry/codegraph
|
|
```
|
|
|
|
The installer will:
|
|
- Ask which agent(s) to configure — auto-detects installed ones from: **Claude Code**, **Cursor**, **Codex CLI**, **opencode**, **Hermes Agent**
|
|
- Prompt to install `codegraph` on your PATH (so agents can launch the MCP server)
|
|
- Ask whether configs apply to all your projects or just this one
|
|
- Write each chosen agent's MCP server config + an instructions file (e.g. `CLAUDE.md`, `.cursor/rules/codegraph.mdc`, `~/.codex/AGENTS.md`)
|
|
- Set up auto-allow permissions when Claude Code is one of the targets
|
|
- Initialize your current project (local installs only)
|
|
|
|
**Non-interactive (scripting / CI):**
|
|
|
|
```bash
|
|
codegraph install --yes # auto-detect agents, install global
|
|
codegraph install --target=cursor,claude --yes # explicit target list
|
|
codegraph install --target=auto --location=local # detected agents, project-local
|
|
codegraph install --print-config codex # print snippet, no file writes
|
|
```
|
|
|
|
| Flag | Values | Default |
|
|
|---|---|---|
|
|
| `--target` | `auto`, `all`, `none`, or csv (`claude,cursor,...`) | prompt |
|
|
| `--location` | `global`, `local` | prompt |
|
|
| `--yes` | (boolean) | prompt every step |
|
|
| `--no-permissions` | (boolean) skip Claude auto-allow list | permissions on |
|
|
| `--print-config <id>` | dump snippet for one agent and exit | — |
|
|
|
|
### 2. Restart Your Agent
|
|
|
|
Restart your agent (Claude Code / Cursor / Codex CLI / opencode / Hermes Agent) for the MCP server to load.
|
|
|
|
### 3. Initialize Projects
|
|
|
|
```bash
|
|
cd your-project
|
|
codegraph init -i
|
|
```
|
|
|
|
Builds the per-project knowledge graph index. Also wires up any project-local agent surfaces (e.g. Cursor's `.cursor/rules/codegraph.mdc`) so a single global `codegraph install` works in every project you open — no need to re-run the installer per project.
|
|
|
|
That's it — your agent will use CodeGraph tools automatically when a `.codegraph/` directory exists.

|
<summary><strong>Global Instructions Reference</strong></summary>
|
|
|
|
The installer automatically adds these instructions to `~/.claude/CLAUDE.md`:
|
|
|
|
```markdown
|
|
## CodeGraph
|
|
|
|
CodeGraph builds a semantic knowledge graph of codebases for faster, smarter code exploration.
|
|
|
|
### If `.codegraph/` exists in the project
|
|
|
|
**NEVER call `codegraph_explore` or `codegraph_context` directly in the main session.** These tools return large amounts of source code that fills up main session context. Instead, ALWAYS spawn an Explore agent for any exploration question (e.g., "how does X work?", "explain the Y system", "where is Z implemented?").
|
|
|
|
**When spawning Explore agents**, include this instruction in the prompt:
|
|
|
|
> This project has CodeGraph initialized (.codegraph/ exists). Use `codegraph_explore` as your PRIMARY tool — it returns full source code sections from all relevant files in one call.
|
|
>
|
|
> **Rules:**
|
|
> 1. Follow the explore call budget in the `codegraph_explore` tool description — it scales automatically based on project size.
|
|
> 2. Do NOT re-read files that codegraph_explore already returned source code for. The source sections are complete and authoritative.
|
|
> 3. Only fall back to grep/glob/read for files listed under "Additional relevant files" if you need more detail, or if codegraph returned no results.
|
|
|
|
**The main session may only use these lightweight tools directly** (for targeted lookups before making edits, not for exploration):
|
|
|
|
| Tool | Use For |
|
|
|------|---------|
|
|
| `codegraph_search` | Find symbols by name |
|
|
| `codegraph_callers` / `codegraph_callees` | Trace call flow |
|
|
| `codegraph_impact` | Check what's affected before editing |
|
|
| `codegraph_node` | Get a single symbol's details |
|
|
|
|
### If `.codegraph/` does NOT exist
|
|
|
|
At the start of a session, ask the user if they'd like to initialize CodeGraph:
|
|
|
|
"I notice this project doesn't have CodeGraph initialized. Would you like me to run `codegraph init -i` to build a code knowledge graph?"
|
|

|
|
|
|
1. **Extraction** — [tree-sitter](https://tree-sitter.github.io/) parses source code into ASTs. Language-specific queries extract nodes (functions, classes, methods) and edges (calls, imports, extends, implements).
|
|
|
|
2. **Storage** — Everything goes into a local SQLite database (`.codegraph/codegraph.db`) with FTS5 full-text search.
|
|
|
|
3. **Resolution** — After extraction, references are resolved: function calls → definitions, imports → source files, class inheritance, and framework-specific patterns.
|
|
|
|
4. **Auto-Sync** — The MCP server watches your project using native OS file events. Changes are debounced (2-second quiet window), filtered to source files only, and incrementally synced. The graph stays fresh as you code — no configuration needed.

|
|
```
|
|
|
|
### `codegraph affected`
|
|
|
|
Traces import dependencies transitively to find which test files are affected by changed source files.
|
|
|
|
```bash
|
|
codegraph affected src/utils.ts src/api.ts # Pass files as arguments
|
|
git diff --name-only | codegraph affected --stdin # Pipe from git diff
|
|
codegraph affected src/auth.ts --filter "e2e/*" # Custom test file pattern
|
|
```
|
|
|
|
| Option | Description | Default |
|
|
|--------|-------------|---------|
|
|
| `--stdin` | Read file list from stdin | `false` |
|
|
| `-d, --depth <n>` | Max dependency traversal depth | `5` |
|
|
| `-f, --filter <glob>` | Custom glob to identify test files | auto-detect |
|
|
| `-j, --json` | Output as JSON | `false` |
|
|
| `-q, --quiet` | Output file paths only | `false` |
|
|
|
|
**CI/hook example:**
|
|
|
|
```bash
|
|
#!/usr/bin/env bash
|
|
AFFECTED=$(git diff --name-only HEAD | codegraph affected --stdin --quiet)
|
|
if [ -n "$AFFECTED" ]; then
|
|
npx vitest run $AFFECTED
|
|
fi
|
|
```
|
|
|

|
|
|
|
## MCP Tools
|
|
|
|
When running as an MCP server, CodeGraph exposes these tools to Claude Code:
|
|
|
|
| Tool | Purpose |
|
|
|------|---------|
|
|
| `codegraph_search` | Find symbols by name across the codebase |
|
|
| `codegraph_context` | Build relevant code context for a task |
|
|
| `codegraph_trace` | Trace the call path between two symbols ("how does X reach Y") in one call — each hop with its body inline, following dynamic-dispatch hops (callbacks, React re-render, interface→impl) that grep can't |
|
|
| `codegraph_callers` | Find what calls a function |
|
|
| `codegraph_callees` | Find what a function calls |
|
|
| `codegraph_impact` | Analyze what code is affected by changing a symbol |
|
|
| `codegraph_node` | Get details about a specific symbol (optionally with source code) |
|
|
| `codegraph_explore` | Return source for several related symbols grouped by file, plus a relationship map, in one call |
|
|
| `codegraph_files` | Get indexed file structure (faster than filesystem scanning) |
|
|
| `codegraph_status` | Check index health and statistics |
|
|
|
|
---
|
|
|
|
## Library Usage
|
|
|
|
```typescript
|
|
import CodeGraph from '@colbymchenry/codegraph';
|
|
|
|
const cg = await CodeGraph.init('/path/to/project');
|
|
// Or: const cg = await CodeGraph.open('/path/to/project');
|
|
|
|
await cg.indexAll({
|
|
onProgress: (p) => console.log(`${p.phase}: ${p.current}/${p.total}`)
|
|
});
|
|
|
|
const results = cg.searchNodes('UserService');
|
|
const callers = cg.getCallers(results[0].node.id);
|
|
const context = await cg.buildContext('fix login bug', { maxNodes: 20, includeCode: true, format: 'markdown' });
|
|
const impact = cg.getImpactRadius(results[0].node.id, 2);
|
|
|
|
cg.watch(); // auto-sync on file changes
|
|
cg.unwatch(); // stop watching
|
|
cg.close();
|
|
```
|
|
|
|
---
|
|
|
|
## Configuration
|
|
|
|
There isn't any — CodeGraph is zero-config. It indexes every file whose
|
|
extension maps to a [supported language](#supported-languages) and **respects
|
|
your `.gitignore`**: in git repos via git itself, and in non-git projects by
|
|
reading `.gitignore` files directly (root and nested, the same way git would).
|
|
|
|
What that means in practice:
|
|
|
|
- Anything git ignores — `node_modules`, build output, secrets in `.env` — is
|
|
never indexed. **To keep something out of the graph, add it to `.gitignore`.**
|
|
- There's no config file to write or keep in sync, and nothing to wire up per
|
|
language: support is automatic from the file extension.
|
|
- Files larger than 1 MB are skipped (generated bundles, minified JS, vendored
|
|
blobs) — they cost parse budget for no useful symbols.
|
|
|
|
> Committed files that aren't gitignored *are* indexed, even under `vendor/` or a
|
|
> committed `dist/`. If you commit a dependency or build directory you don't want
|
|
> in the graph, add it to `.gitignore`.
|
|
|
|
## Supported Platforms
|
|
|
|
Every release ships a self-contained build (bundled Node runtime — nothing to
|
|
compile) for all three desktop OSes, on both Intel/AMD (x64) and ARM (arm64):
|
|
|
|
| Platform | Architectures | Install |
|
|
|----------|---------------|---------|
|
|
| Windows | x64, arm64 | PowerShell installer or npm |
|
|
| macOS | x64, arm64 | shell installer or npm |
|
|
| Linux | x64, arm64 | shell installer or npm |
|
|
|
|
See [Get Started](#get-started) for the one-line install commands.
|
|
|
|
## Supported Agents
|
|
|
|
The interactive installer auto-detects and configures each of these — wiring up
|
|
the MCP server and writing its instructions file:
|
|
|
|
- **Claude Code**
|
|
- **Cursor**
|
|
- **Codex CLI**
|
|

## Troubleshooting
|
|
|
|
**"CodeGraph not initialized"** — Run `codegraph init` in your project directory first.
|
|

**Indexing is slow** — Check that `node_modules` and other large directories are excluded. Use `--quiet` to reduce output overhead.
|
|
|
|
**MCP hits `database is locked`** — current builds shouldn't: CodeGraph bundles its own Node runtime and uses Node's built-in `node:sqlite` in WAL mode, where concurrent reads never block on a writer. If you still see it:
|
|
|
|
- **You're on an old (pre-0.9) install.** Reinstall to get the bundled runtime — `curl -fsSL https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.sh | sh` (macOS/Linux), `irm https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.ps1 | iex` (Windows), or `npm i -g @colbymchenry/codegraph@latest`.
|
|
- **`codegraph status` shows `Journal:` other than `wal`** — WAL couldn't be enabled on this filesystem (common on network shares and WSL2 `/mnt`), so reads can block on writes. Move the project (with its `.codegraph/` folder) onto a local disk.
|
|
|
|
**MCP server not connecting** — Ensure the project is initialized/indexed, verify the path in your MCP config, and check that `codegraph serve --mcp` works from the command line.
|
|
|
|
**Missing symbols** — The MCP server auto-syncs on save (wait a couple seconds). Run `codegraph sync` manually if needed. Check that the file's language is supported and isn't excluded by config patterns.
