From b08c2b27af063ea125ae98b17a78ef3ac69903db Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" Date: Sun, 22 Feb 2026 20:27:00 -0700 Subject: [PATCH 1/8] fix: add receiver field to call sites to eliminate false positive edges MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Dogfooding revealed ~52% of call edges were false positives because obj.method() and standalone() both produced identical call records, causing the global fallback to match ANY function with that name. Add an optional receiver field to call site extraction across all 11 language extractors (WASM + Rust native). The builder's global fallback now only fires for standalone calls or this/self/super — method calls on a receiver skip it entirely. Graph edges on self-analysis dropped from ~1742 to 1321 (24% reduction), all removed edges being false positives like insertNode.run() resolving to f run in cli.test.js. --- .../codegraph-core/src/extractors/csharp.rs | 6 + crates/codegraph-core/src/extractors/go.rs | 4 + crates/codegraph-core/src/extractors/java.rs | 4 + .../src/extractors/javascript.rs | 12 + crates/codegraph-core/src/extractors/php.rs | 9 + .../codegraph-core/src/extractors/python.rs | 18 +- crates/codegraph-core/src/extractors/ruby.rs | 3 + .../src/extractors/rust_lang.rs | 8 + crates/codegraph-core/src/types.rs | 1 + docs/proposal-procedural-rules-bridge.md | 258 ------------------ src/builder.js | 10 +- src/extractors/csharp.js | 7 +- src/extractors/go.js | 7 +- src/extractors/java.js | 5 +- src/extractors/javascript.js | 28 +- src/extractors/php.js | 10 +- src/extractors/python.js | 9 +- src/extractors/ruby.js | 5 +- src/extractors/rust.js | 14 +- src/parser.js | 1 + tests/engines/parity.test.js | 1 + tests/parsers/javascript.test.js | 32 +++ 22 files changed, 172 insertions(+), 280 deletions(-) delete mode 100644 docs/proposal-procedural-rules-bridge.md diff --git a/crates/codegraph-core/src/extractors/csharp.rs b/crates/codegraph-core/src/extractors/csharp.rs index 619f1511..08ad7045 100644 --- a/crates/codegraph-core/src/extractors/csharp.rs +++ b/crates/codegraph-core/src/extractors/csharp.rs @@ -199,14 +199,18 @@ fn walk_node(node: &Node, source: &[u8], symbols: &mut FileSymbols) { name: node_text(&fn_node, source).to_string(), line: start_line(node), dynamic: None, + receiver: None, });

These rules capture *behavioral guidance* — what an AI agent (or developer) should do in specific situations — and are scoped to concrete code entities (functions, files, modules) via codegraph's dependency graph. - -The two projects are natural complements: session-graph excels at extracting and storing knowledge from AI conversations, while codegraph maps the structural reality of a codebase. Together they can bridge the gap between *what we know* and *what we should do*. - ---- - -## The Problem - -Today's AI coding assistants operate with two kinds of context: - -1. **Structural context** — what functions exist, what calls what, how files depend on each other. Tools like codegraph provide this. -2. **Conversational context** — what was discussed, decided, and learned across coding sessions. Session-graph captures this as (subject, predicate, object) triplets. - -What's missing is a third kind: **procedural context** — the accumulated rules, conventions, and lessons learned that tell an agent *how to behave* when working with specific parts of a codebase. This knowledge currently lives in: - -- Flat instruction files (CLAUDE.md, .cursorrules, AGENTS.md) -- Developers' heads (tribal knowledge) -- Scattered across past conversations (unstructured) - -None of these are queryable, scoped to code entities, or automatically maintained. - ---- - -## The Proposal: (When, Do, What) Triplets - -### What they are - -A new triplet format that captures conditional, actionable rules: - -| Field | Role | Example | -|-------|------|---------| -| **when** | The trigger condition or context | `editing parser.js`, `import resolution fails`, `adding a new language` | -| **do** | The action to take | `ensure`, `fallback to`, `follow the pattern in` | -| **what** | The target or detail of the action | `WASM grammars are not recompiled`, `parent directory lookup`, `parsers/javascript.js` | - -### How they differ from session-graph's existing triplets - -| | Session-graph (today) | Procedural rules (proposed) | -|---|---|---| -| **Pattern** | (subject, predicate, object) | (when, do, what) | -| **Knowledge type** | Declarative — facts about the world | Procedural — instructions for behavior | -| **Example** | `(FastAPI, uses, Pydantic)` | `(when test times out, do check, what vitest 30s timeout config)` | -| **Answers** | "What is?" / "How are things related?" | "What should I do?" / "What's the rule here?" | -| **Audience** | Understanding and discovery | Action and guidance | - -These are not competing formats. They are complementary layers of the same knowledge graph. A procedural rule *references* entities that declarative triplets *describe*. - ---- - -## Why This Matters - -### 1. AI agents need scoped, actionable rules - -Flat instruction files (CLAUDE.md, etc.) are a blunt instrument. Every instruction applies globally, regardless of what file or function the agent is working on. Procedural rules scoped to specific code entities let an agent ask: - -> "I'm about to modify `resolveImport` in `builder.js` — what rules apply here?" - -And get back targeted guidance instead of reading an entire instruction document. - -### 2. Tribal knowledge becomes queryable - -Every project has unwritten rules: "don't touch that function without updating the cache", "this test is flaky — retry before investigating", "always run the migration after changing the schema". These rules are learned through experience and lost when people leave. Extracting them as structured triplets makes them durable and discoverable. - -### 3. Rules can generate test scenarios - -Each (when, do, what) triplet implies a testable condition: - -``` -Rule: (when: circular dependency detected, do: report, what: full cycle path) -Test: "verify that cycles.js reports the full path when A -> B -> A exists" -``` - -This creates a natural bridge between knowledge management and quality assurance. - -### 4. Cross-project pattern discovery - -Session-graph already aggregates knowledge across 600+ sessions and multiple platforms. Adding procedural rules to that corpus enables questions like: - -- "What common rules apply across all Python projects?" -- "What debugging patterns recur when working with tree-sitter?" -- "Which rules have been violated most often in recent sessions?" - ---- - -## Architecture: Why Separate, How Connected - -### Why the rule system should not live entirely in either project - -| Putting it all in session-graph | Putting it all in codegraph | -|---|---| -| Would require tree-sitter parsing and code dependency resolution — outside session-graph's scope | Would require LLM extraction pipelines and RDF/SPARQL storage — outside codegraph's scope | -| No way to scope rules to actual code entities without duplicating codegraph's work | No way to extract rules from conversations without duplicating session-graph's work | -| Session-graph stays focused on conversation knowledge | Codegraph stays focused on code structure | - -### The three-layer architecture - -``` -┌─────────────────────┐ ┌─────────────────────┐ -│ session-graph │ │ codegraph │ -│ │ procedural rules │ │ -│ - Extracts rules │ (when, do, what) │ - Maps functions, │ -│ from AI sessions │ ───────────────────────► │ files, deps │ -│ - Stores as RDF │ │ - Attaches rules │ -│ - Queries via │ ◄─────────────────────── │ to graph nodes │ -│ SPARQL │ "what code entities │ - Serves scoped │ -│ │ exist in this file?" │ rules to agents │ -└──────────┬──────────┘ └──────────┬──────────┘ - │ │ - │ ┌──────────────┐ │ - └─────────────►│ bridge │◄────────────────┘ - │ │ - │ - Protocol │ - │ contract │ - │ - Hooks / │ - │ optional │ - │ adapters │ - └──────────────┘ -``` - -**Session-graph** owns: -- Extracting (when, do, what) triplets from conversation history using its LLM pipeline -- Storing them in its RDF triplestore alongside existing declarative triplets -- Exposing them via SPARQL for querying - -**Codegraph** owns: -- Mapping the code's structural reality (symbols, functions, dependencies, call graphs) -- Receiving rules and scoping them to specific graph nodes (functions, files, modules) -- Serving scoped rules to AI agents via its CLI or MCP interface - -**The bridge** is a thin contract between the two: -- A shared schema for rule exchange (JSON-LD, simple JSON, or direct SPARQL) -- Optional hooks so either tool can call the other -- No hard dependency — both projects work fully standalone without the bridge - -### Example hook interactions - -```bash -# Codegraph asks session-graph: "what rules apply to this symbol?" -# (via SPARQL endpoint or exported file) -curl "http://localhost:3030/kg/sparql" \ - --data-urlencode "query= - SELECT ?when ?do ?what WHERE { - ?rule a :ProceduralRule ; - :appliesTo 'resolveImport' ; - :when ?when ; - :do ?do ; - :what ?what . - }" - -# Session-graph asks codegraph: "what symbols exist in this file?" -# (via CLI or MCP) -codegraph query --file src/builder.js --format json -``` - ---- - -## Benefits for Each Project - -### For session-graph - -- **New knowledge category** — procedural rules extend the graph's expressiveness beyond declarative facts, making the knowledge base more complete and actionable -- **Higher-value output** — rules that tell agents what to *do* are immediately useful, increasing adoption and practical impact -- **Natural fit** — the LLM extraction pipeline already processes assistant messages; extending the predicate vocabulary to include procedural predicates (`whenCondition`, `doAction`, `whatTarget`) is incremental work -- **Differentiation** — no other conversation-to-knowledge tool produces scoped, actionable rules - -### For codegraph - -- **Richer graph annotations** — code structure plus behavioral rules is more useful than structure alone -- **New MCP capabilities** — AI agents querying codegraph can receive not just "what calls what" but "what to watch out for when modifying this" -- **Complements existing instruction files** — rules extracted from real sessions are more specific and numerous than hand-written CLAUDE.md instructions -- **No added complexity in core** — codegraph only needs to consume rules, not extract or store them in RDF - -### For the broader AI-assisted development ecosystem - -- **Structured alternative to flat instruction files** — moves beyond CLAUDE.md / .cursorrules toward queryable, scoped guidance -- **Knowledge that improves with use** — every coding session potentially generates new rules, creating a flywheel -- **Open and interoperable** — RDF/SPARQL is a standard; any tool can produce or consume these rules - ---- - -## Concrete Next Steps - -### Phase 1: Define the schema - -Agree on the procedural rule triplet schema. Proposed RDF predicates to add to session-graph's ontology: - -```turtle -:ProceduralRule a owl:Class . -:whenCondition a owl:DatatypeProperty ; rdfs:domain :ProceduralRule . -:doAction a owl:DatatypeProperty ; rdfs:domain :ProceduralRule . -:whatTarget a owl:DatatypeProperty ; rdfs:domain :ProceduralRule . -:appliesTo a owl:ObjectProperty ; rdfs:domain :ProceduralRule ; - rdfs:range :CodeEntity . -:confidence a owl:DatatypeProperty ; rdfs:domain :ProceduralRule ; - rdfs:range xsd:float . -:sourceSession a owl:ObjectProperty ; rdfs:domain :ProceduralRule . -``` - -### Phase 2: Extraction (session-graph side) - -Extend session-graph's LLM extraction to identify procedural rules in assistant messages. Many already exist implicitly: - -> "When you modify the parser, make sure to run the WASM build step first." - -Becomes: - -```turtle -:rule_042 a :ProceduralRule ; - :whenCondition "modifying the parser" ; - :doAction "run first" ; - :whatTarget "WASM build step" ; - :appliesTo :parser_module ; - :sourceSession :session_287 . -``` - -### Phase 3: Consumption (codegraph side) - -Add an optional `rules` command or MCP tool to codegraph that: -- Reads rules from a SPARQL endpoint or JSON export -- Matches `appliesTo` references to codegraph's symbol/file nodes -- Returns scoped rules when querying a specific function or file - -### Phase 4: Bridge and hooks - -Formalize the hook contract so the two tools can optionally call each other. This could start as simple as a shared JSON file and evolve into live API calls. - ---- - -## Open Questions - -1. **Extraction prompt design** — what prompt template best identifies procedural rules in conversation history? This likely needs experimentation with session-graph's existing pipeline. -2. **Entity resolution** — how do we match a rule's `appliesTo` field (a natural language reference like "the parser") to codegraph's concrete symbols (`parser.js:extractFunctions`)? Session-graph's Wikidata linking approach may inform this. -3. **Rule lifecycle** — how do we detect and retire stale rules when code changes? Codegraph's incremental hash tracking could signal when rules need revalidation. -4. **Granularity** — should rules attach at file level, function level, or both? Codegraph supports both, but extraction accuracy may vary. - ---- - -## Closing - -Session-graph turns conversations into knowledge. Codegraph turns code into structure. Procedural rules — (when, do, what) — are the missing bridge that turns both into *actionable guidance* for AI agents working on real codebases. - -The proposed architecture keeps both projects focused on what they do best, connected by a thin protocol that either side can adopt incrementally. No hard dependencies, no scope creep — just a shared format that multiplies the value of both tools. - -I'd welcome your thoughts on the schema, the extraction approach, and whether this aligns with where you see session-graph heading. - ---- - -*This proposal is a starting point for discussion, not a final specification.* diff --git a/src/builder.js b/src/builder.js index c25c6f7b..0bb182c5 100644 --- a/src/builder.js +++ b/src/builder.js @@ -493,10 +493,16 @@ export async function buildGraph(rootDir, opts = {}) { );

engine v0.1.0 +**Tested on:** codegraph's own codebase (87 files, 443 nodes, 1393 edges) + +--- + +## Part 1: Dogfood Findings + +### Critical Bug Found & Fixed + +**MCP server crash with `@modelcontextprotocol/sdk` >= 1.26.0** +- `server.setRequestHandler('tools/list', ...)` crashes with `Schema is missing a method literal` +- Root cause: SDK breaking change — `setRequestHandler` now requires Zod schema objects (`ListToolsRequestSchema`, `CallToolRequestSchema`) instead of string method names +- Since `package.json` specifies `^1.0.0`, users installing fresh get the incompatible version +- **Fix applied:** Import schema objects from `@modelcontextprotocol/sdk/types.js` and use them instead of strings +- **Files changed:** `src/mcp.js`, `tests/unit/mcp.test.js` + +### Call Resolution False Positives (Most Impactful Quality Issue) + +The function-level call graph has significant false positives from **name collision**. Any call to a common method name gets resolved to the wrong function: + +| Call site | Actual target | Resolved to | +|-----------|---------------|-------------| +| `insertNode.run(...)` in builder.js | SQLite prepared statement `.run()` | `f run` in tests/integration/cli.test.js:42 | +| `deleteEdgesForFile.run(...)` | SQLite prepared statement | same test `run` | +| `upsertHash.run(...)` | SQLite prepared statement | same test `run` | +| `path.normalize(...)` in resolve.js | Node.js built-in | `f normalize` in tests/engines/parity.test.js:65 | + +**Impact:** `buildGraph` shows 23 callees, but 12 (52%) are false positives. Every function that calls `db.run()` appears to call the test helper. This makes the call graph unreliable for understanding code flow. + +**Root cause:** Call resolution treats any `identifier(...)` call as a match for any global function with that name, without considering: +1. **Receiver/qualifier context** — `stmt.run()` is a method call on `stmt`, not a call to a standalone `run` function +2. **Import scope** — `run` is never imported in `builder.js`, so it can't be called directly +3. **File boundary** — test files shouldn't be callee candidates for source files (unless explicitly imported) + +### Duplicate Call Edges + +Many caller/callee relationships appear multiple times: +- `buildGraph` → `run`: appears 12 times (once per call site, but all resolve to the same target) +- `normalizePath` appears 6x as callee of `resolveImportPathJS` +- `tests/unit/db.test.js` appears 3x as caller of `openDb` + +Expected behavior: each unique caller→callee pair should appear once, optionally with a count of call sites. + +### Missing Symbols + +- **`cli.js` shows 0 symbols** — Commander-style `program.command(...).action(async () => {...})` callbacks are not extracted. This is the main entry point and has the most complex orchestration logic. +- **`.cjs` files show 0 symbols** — `scripts/gen-deps.cjs` and others have `module.exports` and `require()` patterns that aren't extracted (CommonJS). +- **Prepared statements not tracked** — `const insertNode = db.prepare(...)` creates callable objects that are used throughout, but they're just `const` assignments, not function definitions. + +### Other Observations + +| Area | Finding | Severity | +|------|---------|----------| +| `fn` search | Substring matching: `fn run` returns `pruneRegistry` (contains "run") first | Low — but confusing when looking for exact names | +| `fn` disambiguation | When multiple matches exist, all results are shown but without guidance on which is most relevant | Low | +| `diff-impact` | Shows `changedFiles: 5, affectedFunctions: 0` in worktree — the 5 changed files are probably build artifacts, but they're not function-bearing | Low | +| `hotspots` | No `--functions` flag — only file-level hotspots available | Feature gap | +| `cycles --functions` | Works correctly; found the real `walkPythonNode ↔ findPythonParentClass` mutual recursion | Good | +| `search` | Semantic search works well with good ranking | Good | +| `stats` | Clean summary, correct data | Good | +| `structure` | Excellent output with cohesion scores | Good | +| All `--json` flags | Work correctly across all commands | Good | +| Error messages | Clean, helpful messages for missing files/functions | Good | + +### Test Suite + +- **423/423 tests pass** (5 skipped, all for platform-specific reasons) +- Test suite runs in ~2.3 seconds — fast + +--- + +## Part 2: Improvement Plan for AI Agent Usage + +The goal: make codegraph the **essential first tool** an AI agent uses when working on any codebase. Every improvement below targets a specific problem AI agents (like Claude) face. + +### Priority 1: Fix Call Resolution Accuracy (HIGH IMPACT) + +**Problem:** AI agents trust the call graph to understand what code does. With 52% false positives on common function names, agents will waste tokens investigating wrong call chains, make incorrect assumptions about dependencies, and suggest changes that break things they didn't know were related. + +**Solution: Qualified Call Resolution** + +1. **Distinguish method calls from function calls** + - `obj.method()` should only match methods defined on that object's type or prototype + - `standalone()` should only match imported/in-scope standalone functions + - Implementation: During extraction, tag call sites with their receiver (if any). During resolution, only match method calls to methods and standalone calls to functions. + +2. **Respect import scope** + - A call to `foo()` in file A should only resolve to a function `foo` if: + - `foo` is defined in file A, OR + - `foo` is imported (directly or via re-export) in file A, OR + - `foo` is a global/built-in (and should be excluded) + - This alone would eliminate most false positives. + +3. **Deduplicate call edges** + - Store unique `(caller, callee)` pairs with an optional `count` field + - Display: `-> openDb (calls, 3 sites) src/db.js:72` instead of 3 duplicate lines + +4. **Exclude built-in/library calls** + - `db.run()`, `path.normalize()`, `console.log()`, `Array.map()` etc. are not user code + - Don't create edges for calls where the receiver is a known library/built-in object + - Optionally, create a separate "external calls" edge type for traceability + +### Priority 2: New `context` Command (HIGH IMPACT) + +**Problem:** When an AI agent needs to understand or modify a function, it currently must: +1. Use `fn` to find the function and its call chain (tokens for parsing output) +2. Read the source file to see the implementation (tokens for file content) +3.
