+The tool handles 20K-node kernel subsystems without timeouts. Deep traces on well-connected probe functions (out_degree=59) produce massive but complete results. Community detection identified 734 clusters -- useful for understanding driver module boundaries.
+
+---
+
+## Cross-Cutting Findings
+
+### Strengths
+1. **Zero indexing failures** across 35 repos of all sizes (78 to 49K nodes)
+2. **100% on 17 languages** -- half the languages achieved perfect scores
+3. **No language below 62%** -- even the weakest performs core operations
+4. **Massive codebases handled**: Django (49K nodes), Laravel (38K nodes), neovim (24K nodes) -- no performance issues
+5. **Kernel-scale stress test passed**: 20K nodes, 67K edges, 129K-char traces, zero timeouts
+6. **"Removed" languages still strong**: Obj-C (100%), Perl (100%), Groovy (100%), Swift (95%), Dart (87%)
+
+### Common PARTIAL Patterns
+- **Q10 (Properties)**: Most languages return functions with `properties=null`. Parameter/return extraction is incomplete -- this is the single most common deduction
+- **Q7/Q8 (Trace)**: Abstract methods, entry-point functions, and built-in references correctly return 0 edges (no false positives), but are graded PARTIAL when no alternative function has edges
+- **Q11 (Inheritance)**: Languages using alternative paradigms (traits, protocols, typeclasses, modules) have limited INHERITS edges
+
+### Known Limitations
+1. **Function properties**: Parameter types and return types are not extracted for most languages, resulting in `properties=null`
+2. **Haskell call tracing**: Function composition (`f . g . h`) is not modeled as CALLS edges. Only explicit function applications are traced
+3. **OCaml call analysis**: Limited call resolution due to module functor indirection
+4. **Cypher `IS NOT NULL`**: Not supported in the Cypher parser -- use alternative query patterns
+5. **Scala/Ruby trace**: Abstract methods and block-based patterns can have 0 trace edges
+6. **query_graph 200-row cap**: Aggregation queries (COUNT) silently undercount on large codebases

**Stop paying 100x more tokens for code exploration.** This MCP server indexes your codebase into a persistent knowledge graph that survives session restarts and context compaction. One graph query returns what would take dozens of grep/Glob calls — precise structural results in ~500 tokens vs ~80K tokens for file-by-file exploration.

+# Codebase Knowledge Graph
+
+This project has a code knowledge graph available via MCP tools. Use it for
+structural questions instead of grep — one graph query returns what would take
+dozens of file-by-file searches.
+
+## Finding Code
+
+- "Who calls X?" → use `trace_call_path` with `direction=inbound`
+- "What does X call?" → use `trace_call_path` with `direction=outbound`
+- "Find functions matching pattern" → use `search_graph` with `name_pattern`
+- "Find all routes" → use `search_graph` with `label=Route`
+- "Show codebase structure" → use `get_graph_schema` for overview
+
+## Tracing Dependencies
+
+- Always discover exact names first: `search_graph(name_pattern=".*Partial.*")`
+- Then trace: `trace_call_path(function_name="ExactName", direction="both")`
+- Cross-service HTTP calls: `query_graph("MATCH (a)-[r:HTTP_CALLS]->(b) RETURN a.name, b.name, r.url_path")`
+- Read source: `get_code_snippet(qualified_name="project.path.FunctionName")`
+
+## Quality Analysis
+
+- Dead code: `search_graph` with `max_degree=0`, `exclude_entry_points=true`, `relationship=CALLS`, `direction=inbound`
+- High fan-out: `search_graph` with `min_degree=10`, `relationship=CALLS`, `direction=outbound`
+- Change coupling: `query_graph("MATCH (a)-[r:FILE_CHANGES_WITH]->(b) WHERE r.coupling_score >= 0.5 RETURN ...")`
+
+## Important
+
+- Always check `list_projects` first — run `index_repository` if the project is missing
+- Use `search_graph` to discover exact names before `trace_call_path` (it requires exact match)
+- The graph doesn't index text content — use grep for string literals, error messages, config values
+- Results default to 10 per page — check `has_more` and use `offset` to paginate
+- Use `project` parameter when multiple repos are indexed

+
+# Codebase Exploration via Knowledge Graph
+
+Use graph tools for structural code questions. They return precise results in ~500 tokens vs ~80K for grep-based exploration.
+
+## Workflow
+
+### Step 1: Check if project is indexed
+
+```
+list_projects
+```
+
+If the project is missing from the list:
+
+```
+index_repository(repo_path="/path/to/project")
+```
+
+If already indexed, skip — auto-sync keeps the graph fresh.
+
+### Step 2: Get a structural overview
+
+```
+get_graph_schema
+```
+
+This returns node label counts (functions, classes, routes, etc.), edge type counts, and relationship patterns. Use it to understand what's in the graph before querying.
+
+### Step 3: Find specific code elements
+
+Find functions by name pattern:
+```
+search_graph(label="Function", name_pattern=".*Handler.*")
+```
+
+Find classes:
+```
+search_graph(label="Class", name_pattern=".*Service.*")
+```
+
+Find all REST routes:
+```
+search_graph(label="Route")
+```
+
+Find modules/packages:
+```
+search_graph(label="Module")
+```
+
+Scope to a specific directory:
+```
+search_graph(label="Function", qn_pattern=".*services\\.order\\..*")
+```
+
+### Step 4: Read source code
+
+After finding a function via search, read its source:
+```
+get_code_snippet(qualified_name="project.path.to.FunctionName")
+```
+
+### Step 5: Understand structure
+
+For file/directory exploration within the indexed project:
+```
+list_directory(path="src/services")
+```
+
+## When to Use Grep Instead
+
+- Searching for **string literals** or error messages → `search_code` or Grep
+- Finding a file by exact name → Glob
+- The graph doesn't index text content, only structural elements
+
+## Key Tips
+
+- Results default to 10 per page. Check `has_more` and use `offset` to paginate.
+- Use `project` parameter when multiple repos are indexed.
+- Route nodes have a `properties.handler` field with the actual handler function name.
+- `exclude_labels` removes noise (e.g., `exclude_labels=["Route"]` when searching by name pattern).

+
+# Code Quality Analysis via Knowledge Graph
+
+Use graph degree filtering to find dead code, high-complexity functions, and refactor candidates — all in single tool calls.
+
+## Workflow
+
+### Dead Code Detection
+
+Find functions with zero inbound CALLS edges, excluding entry points:
+
+```
+search_graph(
+ label="Function",
+ relationship="CALLS",
+ direction="inbound",
+ max_degree=0,
+ exclude_entry_points=true
+)
+```
+
+`exclude_entry_points=true` removes route handlers, `main()`, and framework-registered functions that have zero callers by design.
+
+### Verify Dead Code Candidates
+
+Before deleting, verify each candidate truly has no callers:
+
+```
+trace_call_path(function_name="SuspectFunction", direction="inbound", depth=1)
+```
+
+Also check for read references (callbacks, stored in variables):
+
+```
+query_graph(query="MATCH (a)-[r:USAGE]->(b) WHERE b.name = 'SuspectFunction' RETURN a.name, a.file_path LIMIT 10")
+```
+
+### High Fan-Out Functions (calling 10+ others)
+
+These are often doing too much and are refactor candidates:
+
+```
+search_graph(
+ label="Function",
+ relationship="CALLS",
+ direction="outbound",
+ min_degree=10
+)
+```
+
+### High Fan-In Functions (called by 10+ others)
+
+These are critical functions — changes have wide impact:
+
+```
+search_graph(
+ label="Function",
+ relationship="CALLS",
+ direction="inbound",
+ min_degree=10
+)
+```
+
+### Files That Change Together (Hidden Coupling)
+
+Find files with high git change coupling:
+
+```
+query_graph(query="MATCH (a)-[r:FILE_CHANGES_WITH]->(b) WHERE r.coupling_score >= 0.5 RETURN a.name, b.name, r.coupling_score, r.co_change_count ORDER BY r.coupling_score DESC LIMIT 20")
+```
+
+High coupling between unrelated files suggests hidden dependencies.
+
+### Unused Imports
+
+```
+search_graph(
+ relationship="IMPORTS",
+ direction="outbound",
+ max_degree=0,
+ label="Module"
+)
+```
+
+## Key Tips
+
+- `search_graph` with degree filters has no row cap (unlike `query_graph` which caps at 200).
+- Use `file_pattern` to scope analysis to specific directories: `file_pattern="**/services/**"`.
+- Dead code detection works best after a full index — run `index_repository` if the project was recently set up.
+- Paginate results with `limit` and `offset` — check `has_more` in the response.

+# Codebase Memory MCP — Tool Reference
+
+## Tools (12 total)
+
+| Tool | Purpose |
+|------|---------|
+| `index_repository` | Parse and ingest repo into graph (only once — auto-sync keeps it fresh) |
+| `index_status` | Check indexing status (ready/indexing/not found) |
+| `list_projects` | List all indexed projects with timestamps and counts |
+| `delete_project` | Remove a project from the graph |
+| `search_graph` | Structured search with filters (name, label, degree, file pattern) |
+| `search_code` | Grep-like text search within indexed project files |
+| `trace_call_path` | BFS call chain traversal (exact name match required) |
+| `query_graph` | Cypher-like graph queries (200-row cap) |
+| `get_graph_schema` | Node/edge counts, relationship patterns |
+| `get_code_snippet` | Read source code by qualified name |
+| `read_file` | Read any file from indexed project |
+| `list_directory` | List files/directories with glob filter |
+
+## Edge Types
+
+| Type | Meaning |
+|------|---------|
+| `CALLS` | Direct function call within same service |
+| `HTTP_CALLS` | Synchronous cross-service HTTP request |
+| `ASYNC_CALLS` | Async dispatch (Cloud Tasks, Pub/Sub, SQS, Kafka) |
+| `IMPORTS` | Module/package import |
+| `DEFINES` / `DEFINES_METHOD` | Module/class defines a function/method |
+| `HANDLES` | Route node handled by a function |
+| `IMPLEMENTS` | Type implements an interface |
+| `OVERRIDE` | Struct method overrides an interface method |
+| `USAGE` | Read reference (callback, variable assignment) |
+| `FILE_CHANGES_WITH` | Git history change coupling |
+| `CONTAINS_FILE` / `CONTAINS_FOLDER` / `CONTAINS_PACKAGE` | Structural containment |
+
+## Node Labels
+
+`Project`, `Package`, `Folder`, `File`, `Module`, `Class`, `Function`, `Method`, `Interface`, `Enum`, `Type`, `Route`
+
+## Qualified Name Format
+
+`..` — file path with `/` replaced by `.`, extension removed.
+
+Examples:
+- `myproject.cmd.server.main.HandleRequest` (Go)
+- `myproject.services.orders.ProcessOrder` (Python)
+- `myproject.src.components.App.App` (TypeScript)
+
+Use `search_graph` to discover qualified names, then pass them to `get_code_snippet`.
+
+## Cypher Subset (for query_graph)
+
+**Supported:**
+- `MATCH` with node labels and relationship types
+- Variable-length paths: `-[:CALLS*1..3]->`
+- `WHERE` with `=`, `<>`, `>`, `<`, `>=`, `<=`, `=~` (regex), `CONTAINS`, `STARTS WITH`
+- `WHERE` with `AND`, `OR`, `NOT`
+- `RETURN` with property access, `COUNT(x)`, `DISTINCT`
+- `ORDER BY` with `ASC`/`DESC`
+- `LIMIT`
+- Edge property access: `r.confidence`, `r.url_path`, `r.coupling_score`
+
+**Not supported:** `WITH`, `COLLECT`, `SUM`, `CREATE/DELETE/SET`, `OPTIONAL MATCH`, `UNION`
+
+## Common Cypher Patterns
+
+```
+# Cross-service HTTP calls with confidence
+MATCH (a)-[r:HTTP_CALLS]->(b) RETURN a.name, b.name, r.url_path, r.confidence LIMIT 20
+
+# Filter by URL path
+MATCH (a)-[r:HTTP_CALLS]->(b) WHERE r.url_path CONTAINS '/orders' RETURN a.name, b.name
+
+# Interface implementations
+MATCH (s)-[r:OVERRIDE]->(i) RETURN s.name, i.name LIMIT 20
+
+# Change coupling
+MATCH (a)-[r:FILE_CHANGES_WITH]->(b) WHERE r.coupling_score >= 0.5 RETURN a.name, b.name, r.coupling_score
+
+# Functions calling a specific function
+MATCH (f:Function)-[:CALLS]->(g:Function) WHERE g.name = 'ProcessOrder' RETURN f.name LIMIT 20
+```
+
+## Critical Pitfalls
+
+1. **`search_graph(relationship="HTTP_CALLS")` does NOT return edges** — it filters nodes by degree. Use `query_graph` with Cypher to see actual edges.
+2. **`query_graph` has a 200-row cap** before aggregation — COUNT queries silently undercount on large codebases. Use `search_graph` with `min_degree`/`max_degree` for counting.
+3. **`trace_call_path` needs exact names** — use `search_graph(name_pattern=".*Partial.*")` first to discover names.
+4. **`direction="outbound"` misses cross-service callers** — use `direction="both"` for full context.
+
+## Decision Matrix
+
+| Question | Use |
+|----------|-----|

+description: >
+ This skill should be used when the user asks "who calls this function",
+ "what does X call", "trace the call chain", "find callers of",
+ "show dependencies", "what depends on", "trace call path",
+ "find all references to", "impact analysis", or needs to understand
+ function call relationships and dependency chains.
+---
+
+# Call Chain Tracing via Knowledge Graph
+
+Use graph tools to trace function call relationships. One `trace_call_path` call replaces dozens of grep searches across files.
+
+## Workflow
+
+### Step 1: Discover the exact function name
+
+`trace_call_path` requires an **exact** name match. If you don't know the exact name, discover it first:
+
+```
+search_graph(name_pattern=".*Order.*", label="Function")
+```
+
+This returns matching functions with their qualified names and file locations.
+
+### Step 2: Trace callers (who calls this function?)
+
+```
+trace_call_path(function_name="ProcessOrder", direction="inbound", depth=3)
+```
+
+Returns a hop-by-hop list of all functions that call `ProcessOrder`, up to 3 levels deep.
+
+### Step 3: Trace callees (what does this function call?)
+
+```
+trace_call_path(function_name="ProcessOrder", direction="outbound", depth=3)
+```
+
+### Step 4: Full context (both callers and callees)
+
+```
+trace_call_path(function_name="ProcessOrder", direction="both", depth=3)
+```
+
+**Always use `direction="both"` for complete context.** Cross-service HTTP_CALLS edges from other services appear as inbound edges — `direction="outbound"` alone misses them.
+
+### Step 5: Read suspicious code
+
+After finding interesting callers/callees, read their source:
+
+```
+get_code_snippet(qualified_name="project.path.module.FunctionName")
+```
+
+## Cross-Service HTTP Calls
+
+To see all HTTP links between services with URLs and confidence scores:
+
+```
+query_graph(query="MATCH (a)-[r:HTTP_CALLS]->(b) RETURN a.name, b.name, r.url_path, r.confidence ORDER BY r.confidence DESC LIMIT 20")
+```
+
+Filter by URL path:
+```
+query_graph(query="MATCH (a)-[r:HTTP_CALLS]->(b) WHERE r.url_path CONTAINS '/orders' RETURN a.name, b.name, r.url_path")
+```
+
+## Async Dispatch (Cloud Tasks, Pub/Sub, etc.)
+
+Find dispatch functions by name pattern, then trace:
+```
+search_graph(name_pattern=".*CreateTask.*|.*send_to_pubsub.*")
+trace_call_path(function_name="CreateMultidataTask", direction="both")
+```
+
+## Interface Implementations
+
+Find which structs implement an interface method:
+```
+query_graph(query="MATCH (s)-[r:OVERRIDE]->(i) WHERE i.name = 'Read' RETURN s.name, i.name LIMIT 20")
+```
+
+## Read References (callbacks, variable assignments)
+
+```
+query_graph(query="MATCH (a)-[r:USAGE]->(b) WHERE b.name = 'ProcessOrder' RETURN a.name, a.file_path LIMIT 20")
+```
+
+## Key Tips
+
+- Start with `depth=1` for quick answers, increase only if needed (max 5).
+- Edge types in trace results: `CALLS` (direct), `HTTP_CALLS` (cross-service), `ASYNC_CALLS` (async dispatch), `USAGE` (read reference), `OVERRIDE` (interface implementation).
+- `search_graph(relationship="HTTP_CALLS")` filters nodes by degree — it does NOT return edges. Use `query_graph` with Cypher to see actual edges with properties.
+- Results are capped at 200 nodes per trace.
