From bb23ea4a5532c2981b67629225b38eb3de9f6958 Mon Sep 17 00:00:00 2001 From: Andrew Hundt Date: Fri, 20 Mar 2026 00:02:43 -0400 Subject: [PATCH 01/65] mcp: reduce token consumption via RTK-inspired filtering strategies MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Apply 8 token reduction techniques inspired by RTK (Rust Token Killer): 1. Default search limits: search_graph/search_code default limit 500K→50 (CBM_DEFAULT_SEARCH_LIMIT constant). Callers can override explicitly. 2. Smart truncation for get_code_snippet: 3 modes (full/signature/head_tail) with max_lines=200 default (CBM_DEFAULT_SNIPPET_MAX_LINES). head_tail preserves function signature + return/cleanup code. Signature mode returns only API surface without reading source files. 3. Compact mode for search_graph/trace_call_path: omits redundant name field when it's the last segment of qualified_name. 4. Summary mode for search_graph: returns aggregated counts by label and file (top 20) instead of individual results. 95% token reduction. 5. Trace edge case fixes: max_results param (default 25), BFS cycle deduplication by node ID, candidates array for ambiguous function names, callees_total/callers_total counts. 6. query_graph output truncation: max_output_bytes (default 32KB) caps worst-case output. Does NOT change max_rows (which is a scan-limit that would break aggregation queries). 7. Token metadata: _result_bytes and _est_tokens in all MCP tool responses for LLM token awareness. 8. Stable pagination: ORDER BY name, id for deterministic pagination. All defaults use named constants (CBM_DEFAULT_*) — no magic numbers. CYPHER_RESULT_CEILING reduced 100K→10K as safety net. Tests: 22 new tests in test_token_reduction.c, all passing. All 2060+ existing tests pass with zero regressions. --- Makefile.cbm | 6 +- src/cypher/cypher.c | 2 +- src/mcp/mcp.c | 300 +++++++++++-- src/store/store.c | 5 +- tests/test_main.c | 8 + tests/test_token_reduction.c | 826 +++++++++++++++++++++++++++++++++++ 6 files changed, 1104 insertions(+), 43 deletions(-) create mode 100644 tests/test_token_reduction.c diff --git a/Makefile.cbm b/Makefile.cbm index 666a9455..6dc5e369 100644 --- a/Makefile.cbm +++ b/Makefile.cbm @@ -286,7 +286,11 @@ TEST_MEM_SRCS = tests/test_mem.c TEST_UI_SRCS = tests/test_ui.c -ALL_TEST_SRCS = $(TEST_FOUNDATION_SRCS) $(TEST_EXTRACTION_SRCS) $(TEST_STORE_SRCS) $(TEST_CYPHER_SRCS) $(TEST_MCP_SRCS) $(TEST_DISCOVER_SRCS) $(TEST_GRAPH_BUFFER_SRCS) $(TEST_PIPELINE_SRCS) $(TEST_WATCHER_SRCS) $(TEST_LZ4_SRCS) $(TEST_SQLITE_WRITER_SRCS) $(TEST_GO_LSP_SRCS) $(TEST_C_LSP_SRCS) $(TEST_TRACES_SRCS) $(TEST_HTTPLINK_SRCS) $(TEST_CLI_SRCS) $(TEST_MEM_SRCS) $(TEST_UI_SRCS) $(TEST_INTEGRATION_SRCS) +TEST_TOKEN_REDUCTION_SRCS = tests/test_token_reduction.c + +TEST_DEPINDEX_SRCS = tests/test_depindex.c + +ALL_TEST_SRCS = $(TEST_FOUNDATION_SRCS) $(TEST_EXTRACTION_SRCS) $(TEST_STORE_SRCS) $(TEST_CYPHER_SRCS) $(TEST_MCP_SRCS) $(TEST_DISCOVER_SRCS) $(TEST_GRAPH_BUFFER_SRCS) $(TEST_PIPELINE_SRCS) $(TEST_WATCHER_SRCS) $(TEST_LZ4_SRCS) $(TEST_SQLITE_WRITER_SRCS) $(TEST_GO_LSP_SRCS) $(TEST_C_LSP_SRCS) $(TEST_TRACES_SRCS) $(TEST_HTTPLINK_SRCS) $(TEST_CLI_SRCS) $(TEST_MEM_SRCS) $(TEST_UI_SRCS) $(TEST_TOKEN_REDUCTION_SRCS) $(TEST_DEPINDEX_SRCS) $(TEST_INTEGRATION_SRCS) # ── Build directories ──────────────────────────────────────────── diff --git a/src/cypher/cypher.c b/src/cypher/cypher.c index b7e1c159..a4c67a5f 100644 --- a/src/cypher/cypher.c +++ b/src/cypher/cypher.c @@ -1957,7 +1957,7 @@ static void rb_add_row(result_builder_t *rb, const char **values) { // NOLINTNEXTLINE(bugprone-easily-swappable-parameters,readability-function-cognitive-complexity,readability-function-size) /* Hard ceiling: queries returning more than this trigger an error instead of data. * Prevents accidental multi-GB JSON payloads from unbounded MATCH (n) RETURN n. */ -#define CYPHER_RESULT_CEILING 100000 +#define CYPHER_RESULT_CEILING 10000 /* ── Binding virtual variables (for WITH clause) ──────────────── */ diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 3924b868..749f4d8a 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -38,9 +38,24 @@ /* ── Constants ────────────────────────────────────────────────── */ -/* Default snippet fallback line count */ +/* Default snippet fallback line count (when end_line unknown) */ #define SNIPPET_DEFAULT_LINES 50 +/* Default result limit for search_graph and search_code. + * Prevents unbounded 500K-result responses.

charset=UTF-8 Content-Transfer-Encoding: 8bit Register index_dependencies MCP tool for indexing dependency/library source code into a separate dependency graph. Dependencies are stored in {project}_deps.db (separate from project.db) and are NOT included in queries unless include_dependencies=true is passed. AI grounding safeguards (7-layer defense): 1. Storage: separate _deps.db not touched by index_repository 2. Query default: include_dependencies=false (deps excluded by default) 3. QN prefix: dep.{mgr}.{package}.{symbol} convention documented 4. Response field: "source":"project" / "source":"dependency" labels 5. Properties: "external":true on dependency nodes 6. Tool description: explicitly states "SEPARATE dependency graph" 7. Boundary markers: trace_call_path shows project→dep edges Current state: - Tool registered with full parameter validation (project, package_manager required) - include_dependencies param added to search_graph with source field - Handler returns structured "not_yet_implemented" status - Full dep resolution pipeline (depindex module) designed but deferred Tests: 12 new tests in test_depindex.c, all passing. All 2042 existing tests pass with zero regressions. Next: implement src/depindex/ module for actual package resolution (uv/cargo/npm/bun), dependency file discovery, and pipeline integration per the plan in plans/serialized-pondering-puppy.md. --- Makefile.cbm | 4 +- src/mcp/mcp.c | 63 ++++++ tests/test_depindex.c | 486 ++++++++++++++++++++++++++++++++++++++++++ tests/test_main.c | 4 + 4 files changed, 556 insertions(+), 1 deletion(-) create mode 100644 tests/test_depindex.c diff --git a/Makefile.cbm b/Makefile.cbm index 666a9455..817b5489 100644 --- a/Makefile.cbm +++ b/Makefile.cbm @@ -286,7 +286,9 @@ TEST_MEM_SRCS = tests/test_mem.c TEST_UI_SRCS = tests/test_ui.c -ALL_TEST_SRCS = $(TEST_FOUNDATION_SRCS) $(TEST_EXTRACTION_SRCS) $(TEST_STORE_SRCS) $(TEST_CYPHER_SRCS) $(TEST_MCP_SRCS) $(TEST_DISCOVER_SRCS) $(TEST_GRAPH_BUFFER_SRCS) $(TEST_PIPELINE_SRCS) $(TEST_WATCHER_SRCS) $(TEST_LZ4_SRCS) $(TEST_SQLITE_WRITER_SRCS) $(TEST_GO_LSP_SRCS) $(TEST_C_LSP_SRCS) $(TEST_TRACES_SRCS) $(TEST_HTTPLINK_SRCS) $(TEST_CLI_SRCS) $(TEST_MEM_SRCS) $(TEST_UI_SRCS) $(TEST_INTEGRATION_SRCS) +TEST_DEPINDEX_SRCS = tests/test_depindex.c + +ALL_TEST_SRCS = $(TEST_FOUNDATION_SRCS) $(TEST_EXTRACTION_SRCS) $(TEST_STORE_SRCS) $(TEST_CYPHER_SRCS) $(TEST_MCP_SRCS) $(TEST_DISCOVER_SRCS) $(TEST_GRAPH_BUFFER_SRCS) $(TEST_PIPELINE_SRCS) $(TEST_WATCHER_SRCS) $(TEST_LZ4_SRCS) $(TEST_SQLITE_WRITER_SRCS) $(TEST_GO_LSP_SRCS) $(TEST_C_LSP_SRCS) $(TEST_TRACES_SRCS) $(TEST_HTTPLINK_SRCS) $(TEST_CLI_SRCS) $(TEST_MEM_SRCS) $(TEST_UI_SRCS) $(TEST_DEPINDEX_SRCS) $(TEST_INTEGRATION_SRCS) # ── Build directories ──────────────────────────────────────────── diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 3924b868..290c6771 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -304,6 +304,20 @@ static const tool_def_t TOOLS[] = { {"ingest_traces", "Ingest runtime traces to enhance the knowledge graph", "{\"type\":\"object\",\"properties\":{\"traces\":{\"type\":\"array\"},\"project\":{\"type\":" "\"string\"}},\"required\":[\"traces\"]}"}, + + {"index_dependencies", + "Index dependency/library source code into a SEPARATE dependency graph for API reference.

Explicit limit is ignored because summary doesn't return individual results. | +| `mode=summary` + `compact` | search_graph | N/A — summary returns aggregates, not individual results. Compact has no effect. | No `name`/`qualified_name` fields to deduplicate in summary output. | +| `mode=signature` + `max_lines` | get_code_snippet | Signature mode ignores max_lines — it returns signature only (no source read). | Signature mode skips `read_file_lines()` entirely. max_lines is irrelevant. | +| `mode=head_tail` + `max_lines` | get_code_snippet | Both apply: head_tail uses max_lines to compute 60/40 split. | head_count = max_lines*60/100, tail_count = max_lines - head_count. | +| `include_dependencies` + `compact` | search_graph | Both apply. Dep results also get compact treatment. `source` field always present when deps included. | Compact removes `name` from both project and dep results equally. | +| `include_dependencies` + `mode=summary` | search_graph | Both apply.

Default Limit (50 results) + +**Strength**: Prevents accidental 500K-result responses that consume entire context window. Single largest token savings (99.6% on large codebases). + +**Limitation**: Callers relying on "get everything" behavior silently get fewer results. Mitigated by `has_more` flag and `pagination_hint`. + +**Composability**: Limit is the first stage in the pipeline — it reduces input to all subsequent stages (compact, summary, serialization). + +#### 2. Summary Mode + +**Strength**: Reduces a 347-result search to ~1KB of aggregate counts (99.8% savings). Ideal for codebase orientation before targeted queries. + +**Limitation**: Caps aggregation at 10,000 results (sufficient for most codebases). Does not use SQL GROUP BY, so counts are approximate for >10K-symbol projects. Only counts top 20 files. + +**Composability**: Overrides `limit` (uses 10K internally). `compact` has no effect. `include_dependencies` adds dep nodes to counts. + +#### 3. Compact Mode + +**Strength**: Removes redundant `name` field when it matches the last segment of `qualified_name` (72.7% reduction measured). Zero information loss — `qualified_name` always contains the name. + +**Limitation**: Savings depend on naming patterns. Projects with short qualified names see less benefit. The `ends_with_segment()` helper checks `.`, `:`, `/` separators — other separators (e.g., `::` in C++) won't match (but `::` ends with `:` so the second colon is found). + +**Composability**: Independent of all other features. Applied at serialization time. + +#### 4. Signature Mode (get_code_snippet) + +**Strength**: 99.4% token savings. No file I/O — extracts signature from pre-indexed `properties_json`. Instant response. + +**Limitation**: Only works if the indexing pipeline captured the signature in `properties_json`. Some languages or complex signatures may not be fully captured. Returns no source body — callers can't see implementation. + +**Composability**: Overrides `max_lines` (no source to limit). Unaffected by `head_tail`. + +#### 5. Head/Tail Mode (get_code_snippet) + +**Strength**: Preserves function signature (head 60%) and return/cleanup code (tail 40%) while cutting the middle. Solves the blind-truncation problem where important return types and error handling get silently cut. + +**Limitation**: The 60/40 split is fixed (not configurable). For functions where the critical logic is in the middle, this loses important context. If `source_tail` read fails (file truncated between reads), falls back to head-only output. + +**Composability**: Uses `max_lines` for the split calculation. `head_count = max_lines * 60 / 100`. Both `head_count` and `tail_count` are clamped to >= 1. + +#### 6. max_output_bytes (query_graph) + +**Strength**: Caps worst-case Cypher output at 32KB (~8000 tokens). Replaces with a valid JSON metadata object (not mid-JSON truncation) so the LLM can always parse the response. + +**Limitation**: Does NOT limit `max_rows` (scan-time limit), only output size. Aggregation queries (COUNT, etc.) produce small output and are never truncated. The truncation replacement loses all query data — no partial results are returned. + +**Composability**: Independent of other features. Only applies to `query_graph`. + +#### 7. BFS Deduplication + Ambiguity Resolution (trace_call_path) + +**Strength**: Eliminates cycle-inflated caller/callee counts. When multiple functions share the same name, returns a `candidates` array with qualified names so the AI can disambiguate. + +**Limitation**: Dedup is O(N^2) where N=max_results (default 25). At N=25 this is 625 comparisons (negligible). For `max_results=1000` it becomes 500K comparisons — may need hash set upgrade. + +**Composability**: Dedup runs before compact mode — compact sees only unique nodes. + +#### 8. Token Metadata (_result_bytes, _est_tokens) + +**Strength**: Every response includes byte count and estimated token count (bytes/4). Enables LLMs to gauge context cost before requesting more data. + +**Limitation**: Token estimate is approximate (bytes/4 heuristic, same as RTK). Actual tokenization varies by model. Metadata adds ~30 bytes per response. + +**Composability**: Wraps all other features. Always reflects the final serialized output size. + +#### 9. Config-Backed Defaults + +**Strength**: All defaults are runtime-configurable via `config set `. Users can tune without recompilation. + +**Limitation**: Config keys are string-matched — typos fail silently (no validation of key names). No config file documentation beyond SKILL.md and tool schema descriptions. + +**Composability**: Config provides the default, explicit tool parameters override it. Chain: config default -> tool param -> applied. + +#### 10. Stable Pagination (ORDER BY name, id) + +**Strength**: Prevents duplicate/missing results when paginating with `offset`/`limit`. Uses `id` column (not `rowid`) for compatibility with degree-filter subqueries. + +**Limitation**: Pagination is not cursor-based — concurrent index updates between page requests can still cause shifts. `has_more` is computed from total count, which may change between requests. + +**Composability**: Underlying all `search_graph` features. Summary mode bypasses pagination (aggregates all results). + +### Dependency Indexing Features + +#### 11. index_dependencies Tool + +**Strength**: Clean MCP interface with full parameter validation. Schema describes the SEPARATE dependency graph concept clearly. 7-layer AI grounding defense prevents confusion between project and library code. + +**Limitation**: Returns `not_yet_implemented`. The actual package resolution pipeline (uv/cargo/npm/bun) is designed but not built. `packages` and `public_only` parameters are declared in schema but silently ignored. + +**Composability**: When implemented, feeds into `_deps.db` which all query tools can access via `include_dependencies`. + +#### 12. include_dependencies Parameter + +**Strength**: Opt-in by default (false). When true, adds `source:"project"` or `source:"dependency"` field to results for clear provenance. AI can filter or reason about the boundary. + +**Limitation**: Currently no-op — no deps exist to include. The `source` field is only added when `include_dependencies=true`, meaning project-only queries don't get the field (minor inconsistency, but reduces noise). + +**Composability**: Works with `compact` (dep results also get compact treatment), `mode=summary` (deps counted in aggregation), `limit` (deps count toward limit). + +#### 13. AI Grounding (7-Layer Defense) + +**Strength**: Defense-in-depth approach prevents the most dangerous failure mode (AI confusing library code with project code). Each layer independently prevents confusion: + +| Layer | Mechanism | Fails if... | +|-------|-----------|-------------| +| Storage | Separate `_deps.db` | Both dbs queried without flag | +| Query default | `include_dependencies=false` | Default changed to true | +| QN prefix | `dep.uv.pandas.DataFrame` | Prefix stripped or ignored | +| Response field | `"source":"dependency"` | Field missing or wrong | +| Properties | `"external":true` | Property not set during indexing | +| Tool description | Schema says "SEPARATE" | AI ignores tool description | +| Boundary markers | trace shows transitions | Trace doesn't cross boundary | + +**Limitation**: All 7 layers are designed, but layers 1, 3, 5, 7 require the dep pipeline (`src/depindex/`) to be implemented. Currently, layers 2, 4, 6 are active. + +## Architecture: How Features Compose + +```mermaid +graph TB + subgraph Input["Data Layer"] + IDX[index_repository

This is the same pattern RTK uses for its filter configurations. + +### Pattern 2: Opt-In Additive Parameters +All new parameters default to the existing behavior (`compact=false`, `mode="full"`, `include_dependencies=false`). No existing behavior changes unless a caller explicitly opts in. This ensures backward compatibility. + +### Pattern 3: Pipeline Stage Independence +Each token reduction feature operates at a different stage (SQL limit, dedup, mode selection, compact serialization, output cap, metadata). They don't interfere because they're sequentially applied. Adding a new stage only requires inserting it at the right point. + +### Pattern 4: Metadata-First Truncation +When data is truncated, the response always includes metadata about what was lost (`truncated=true`, `total_lines`, `has_more`, `pagination_hint`, `callees_total`). This prevents silent data loss — the AI always knows more data exists. + +### Pattern 5: Provenance Tagging +The `source` field pattern ("project" vs "dependency") is generalizable to other data sources (e.g., "test", "generated", "vendored"). The infrastructure supports arbitrary string tags without schema changes. From b9a1ad59b8c6aaae665b29e1d792a4a9175859d9 Mon Sep 17 00:00:00 2001 From: Andrew Hundt Date: Fri, 20 Mar 2026 23:27:32 -0400 Subject: [PATCH 20/65] depindex: implement dep indexing pipeline, smart project param, search_code fix New module src/depindex/ with package resolution (uv/cargo/npm/bun), ecosystem detection, dep discovery from indexed graph, auto-index helper, and cross-boundary edge creation stub.

charset=UTF-8 Content-Transfer-Encoding: 8bit expand_project_param() (mcp.c:764-840): - "self" → session project exact match - "dep"/"deps" → session.dep prefix match - "dep.pandas" → session.dep.pandas prefix - "myapp.pandas" → myapp.dep.pandas (auto-insert .dep.) - Glob "*" → SQL LIKE with % substitution - fill_project_params() helper sets cbm_search_params_t fields search_graph result tagging (mcp.c:930-960): - Every result tagged source:"project" or source:"dependency" - Dep results get package name + read_only:true - session_project added to response for AI project name awareness - Uses cbm_is_dep_project() with session context for precision handle_index_status (mcp.c:1046-1100): - Reports dependencies[] array with package names and node counts - Reports detected_ecosystem from project root marker files - session_project in response Dep auto-reindex in all 3 re-index paths: - handle_index_repository (mcp.c:1472): cbm_dep_auto_index after dump - watcher_index_fn (main.c:86-96): cbm_dep_auto_index after dump - autoindex_thread (mcp.c:2496-2501): cbm_dep_auto_index after dump All use DRY cbm_dep_auto_index() with CBM_DEFAULT_AUTO_DEP_LIMIT cbm_mcp_server_set_session_project() added (mcp.h:128, mcp.c:526) Fix: yyjson_mut_obj_add_strcpy for dep package names from search results (heap-use-after-free when cbm_store_search_free frees borrowed strings) Fix: db_project selection when session_project is empty (integration test integ_mcp_delete_project was failing — resolve_store got NULL instead of project name after expand_project_param) Tests: 29 depindex tests (2059 total, all passing) - test_search_results_have_source_field: project results tagged - test_search_dep_results_tagged_dependency: dep results have package+read_only - test_search_response_has_session_project: session_project in response - test_index_status_shows_deps: dependencies[] in index_status response --- src/main.c | 14 +++ src/mcp/mcp.c | 234 ++++++++++++++++++++++++++++++++++++++---- src/mcp/mcp.h | 3 + tests/test_depindex.c | 180 ++++++++++++++++++++++++++++++++ 4 files changed, 411 insertions(+), 20 deletions(-) diff --git a/src/main.c b/src/main.c index 79618fad..f39b03cb 100644 --- a/src/main.c +++ b/src/main.c @@ -17,6 +17,7 @@ #include "watcher/watcher.h" #include "pipeline/pipeline.h" #include "store/store.h" +#include "depindex/depindex.h" #include "cli/cli.h" #include "foundation/log.h" #include "foundation/compat_thread.h" @@ -85,6 +86,19 @@ static int watcher_index_fn(const char *project_name, const char *root_path, voi int rc = cbm_pipeline_run(p);

If autoindex_active: join background thread, re-resolve store 2. If still NULL: run cbm_pipeline_run() synchronously, then cbm_dep_auto_index() + cbm_pagerank_compute_with_config() Handles all 3 paths: CWD (detect_session), explicit path (Rule 0), MCP roots (future). access(session_root, F_OK) guard prevents triggering on non-existent paths in tests. inject_context_once(): auto-provide architecture/schema on first response. First tool response gets _context header with: status, nodes, edges, node_labels, edge_types, ranked_nodes, pagerank_computed_at, detected_ecosystem. Subsequent responses only get session_project. Fix: use-after-free in inject_context_once (ASAN crash at mcp.c:937). cbm_store_schema_free() freed label/type strings while yyjson still held borrowed pointers. Fix: yyjson_mut_obj_add_strcpy() copies strings into yyjson's allocator before schema is freed. Fix: _hidden_tools count corrected from "12" to "14" (14 tools hidden).

Resources exposed: - codebase://schema — node labels and edge types with counts - codebase://architecture — graph size, key functions by PageRank, relationship patterns - codebase://status — index status, PageRank stats, ecosystem, dependencies Implementation: - resources/list returns 3 resource URIs with descriptions - resources/read dispatches by URI to build_resource_{schema,architecture,status} - Server advertises resources capability in initialize response (listChanged:true) - Client capabilities.resources parsed from initialize params (client_has_resources flag) - inject_context_once skipped when client supports resources (0 token overhead) - notifications/resources/updated sent after index_repository, index_dependencies, autoindex - Fallback: legacy clients without resources support still get _context injection Tests: 8 new tests (resources_list, resources_read x4, initialize_advertises, client_capability_parsing, fallback_injection).

Descriptions must be self-sufficient — an AI reading just the tool list should know the full workflow. Tool description changes: - search_code_graph: now says "Read codebase://schema for available node labels and edge types before writing Cypher queries" - trace_call_path: now says "Read codebase://architecture for key functions to start tracing from" - get_code: now says "Get qualified_name values from search_code_graph results" - _hidden_tools hint: now lists all 3 resource URIs with usage guidance Resource description changes (more actionable): - codebase://schema: lists example labels, says "Read this before writing Cypher" - codebase://architecture: mentions PageRank, says "Read this first to understand codebase structure and find important entry points" - codebase://status: lists all fields, says "Read this to check if project is indexed" Tests: 2 new tests verify tool descriptions reference resources and _hidden_tools hint mentions all 3 resource URIs.

charset=UTF-8 Content-Transfer-Encoding: 8bit Bug 1: resolve_store opens wrong DB for dep projects Root cause: resolve_store("myapp.dep.pandas") opens myapp.dep.pandas.db instead of myapp.db where deps actually live (same-db design). Fix: parent_project_for_db() strips .dep.* suffix to find parent DB. Bug 2: store.c prefix match was actually exact match Root cause: cbm_store_search with params->project set (non-exact mode) used "n.project = ?" — exact match, not prefix. Deps invisible. Fix: SQL now uses "(n.project = ? OR n.project LIKE ?||'.%')" for prefix mode, so search_graph(project="myapp") returns project + deps. Bug 3: cbm_is_dep_project fails for cross-project deps Root cause: Early return when session_project doesn't match prefix. "otherapp.dep.pandas" with session "myapp" → false (should be true). Fix: Fall through to generic .dep. strstr check when session prefix doesn't match. Any project containing ".dep." is a dependency. Bug 4: Package name extraction used wrong offset Root cause: Used strlen(session_project) as offset into project name, but session_project is CWD-detected, not the indexed project. Fix: Use strstr(project, ".dep.") to find separator position directly.

When session is "Users-athundt-.claude" and the requested project is "Users-athundt-.claude-codebase-memory-mcp-...", the first 22 chars match (shared path prefix), so search incorrectly opened the empty session DB instead of the requested project's 22K-node DB. Fix: after strncmp, also check that pe.value[sp_len] is '.' (dep separator) or '\0' (exact match). This prevents "myapp" from matching "myapp-other-project" while still correctly matching "myapp.dep.pandas". Found by dogfooding: search_code_graph with explicit project name returned 0 results despite DB having 22828 nodes.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three bugs fixed in handle_get_code_snippet: Bug A (root cause): Tiers 1-3 all use WHERE project = ?1 AND ... in SQL. When project param is NULL, SQLite binds NULL and the comparison is always false — all exact/suffix/name lookups silently return 0 rows. Bug B: Tier 4 fuzzy search found 1 result but snippet_suggestions() always sets status=ambiguous regardless of count. Bug C: Dedup block with cand_count==1 after dedup fell through to ambiguous instead of resolving. Fixes: 1. extract_project_from_qn(): scans each dot-prefix of the QN and tests for a matching ~/.cache/codebase-memory-mcp/{prefix}.db file (O(n), ~5-15 access() calls). Returns longest matching prefix — the QN is self-describing so this works even on cold start (no prior search call). Single malloc+memcpy pattern: best_end offset avoids repeated strdup. 2. handle_get_code_snippet: when project param is NULL, calls extract_project_from_qn(qn) and opens the correct DB via resolve_store. Falls back to srv->current_project if no DB found. Assigns result into project (was NULL) so all existing free(project) exit paths own the memory. 3. Tier 4 fuzzy: fuzzy_count==1 now resolves directly (build_snippet_response) instead of calling snippet_suggestions. 4. Dedup block: cand_count==1 after dedup now resolves directly. Tests added (3 new, total 2190): - get_code_no_project_uses_open_store_tier1: after search_graph opens a store, get_code without project resolves via Tier 1 exact QN + eff_project - get_code_single_fuzzy_result_resolves_not_ambiguous: wrong-prefix QN forces Tier 4 fuzzy; single result must not return status=ambiguous - get_code_cold_start_parses_project_from_qn: fresh server, no prior call, extract_project_from_qn finds the DB and resolves the symbol --- src/mcp/mcp.c | 106 ++++++++++++++++++++++++-- tests/test_tool_consolidation.c | 127 ++++++++++++++++++++++++++++++++ 2 files changed, 227 insertions(+), 6 deletions(-) diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 37ebfdee..383373ce 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -816,6 +816,54 @@ static const char *project_db_path(const char *project, char *buf, size_t bufsz) return buf; } +/* ── QN project extraction ─────────────────────────────────────── */ + +/* Try to identify the project prefix of a qualified name by scanning each + * dot-separated prefix and checking if a matching DB file exists. + * Returns a heap-allocated project name (caller must free), or NULL if no + * matching DB is found.

Now any project the AI session interacts with gets registered: - handle_index_repository: call cbm_watcher_watch() after successful index+pagerank, so explicitly indexed projects get auto-reindexed on file changes (same pattern as auto-index thread at lines 3503-3505) - resolve_store: call cbm_store_get_project() to get root_path from DB, then cbm_watcher_watch() when a new store is opened. Only runs on the new-store path (early-return skips already-cached projects). Covers all data-access tool paths: search_code_graph, trace_call_path, get_code.

Empty DBs trigger reindex. New features: - db_is_stale(): compares DB mtime vs git HEAD commit time, with configurable max_age_seconds (reindex_stale_seconds config key) - reindex_on_startup config: when true + stale DB, triggers reindex at server start. Default false for large project safety. DRY refactors: - resolve_project_store(): extracted from handle_search_graph, reused by handle_trace_call_path.

charset=UTF-8 Content-Transfer-Encoding: 8bit Move "third_party", "thirdparty", "3rdparty", "external" from FAST_SKIP_DIRS to ALWAYS_SKIP_DIRS so they're excluded in FULL mode too. Add "vendored" (new) to ALWAYS_SKIP_DIRS. Add prefix-based matching via has_vendored_prefix() for naming variations like "vendored_libs", "vendor-bundle", "third_party_deps". Matches vendor*, 3rdparty*, third_party*, thirdparty* followed by separator or end-of-string. Before: FULL mode indexed vendored grammars → 22,935 nodes, PageRank dominated by vendored scanner functions (eof, seq, View.size). After: 5,300 nodes, PageRank correctly shows core pipeline/store/mcp functions at the top. No entries removed from skip lists — 4 entries promoted FAST→ALWAYS, 1 entry added. DEP mode unaffected (has its own minimal skip list). --- src/discover/discover.c | 40 +++++++++++++++++++++++++++++++++++----- 1 file changed, 35 insertions(+), 5 deletions(-) diff --git a/src/discover/discover.c b/src/discover/discover.c index 6f8f59b4..8e687d25 100644 --- a/src/discover/discover.c +++ b/src/discover/discover.c @@ -39,17 +39,24 @@ static const char *ALWAYS_SKIP_DIRS[] = { ".ccls-cache", ".clangd", "elm-stuff", "_opam", ".cpcache", ".shadow-cljs", /* Deploy */ ".vercel", ".netlify", + /* Vendored / third-party code (always skip — use CBM_MODE_DEP for dep source) */ + "vendor", "vendored", "third_party", "thirdparty", "3rdparty", "external", /* Misc */ - ".qdrant_code_embeddings", ".tmp", "vendor", NULL}; + ".qdrant_code_embeddings", ".tmp", NULL}; + +/* Prefix patterns for vendored directory names that vary (e.g. "vendored_libs", + * "vendor-bundle").

charset=UTF-8 Content-Transfer-Encoding: 8bit Config registry (CBM_CONFIG_REGISTRY in cli.c): - 25 config keys across 5 categories: Indexing, Search, Tools, PageRank, Dependencies. Each entry has key, default, env var name, category, description. - All defaults verified against code-level #define values. cbm_config_get_effective(): priority chain env > DB > default. - Checks registry for env var name, reads env first, falls back to DB. - Used by config get CLI and auto_index in maybe_auto_index. Env var overrides for key settings: - CBM_AUTO_INDEX (bool), CBM_AUTO_INDEX_LIMIT (int) - CBM_REINDEX_ON_STARTUP (bool) - CBM_KEY_FUNCTIONS_EXCLUDE (comma-separated globs) - CBM_TOOL_MODE (streamlined/classic) config list output: - Grouped by category with [Category] headers - Shows (env) when env var is active, (set) when DB value differs from default - All 25 keys visible (was: only 2) config help: - Shows storage location (~/.cache/codebase-memory-mcp/_config.db) - Priority explanation (env > config set > default) - Examples for config set and env var usage - Keys grouped by category with [env: VAR_NAME] annotation Fixed: auto_dep_limit default 5→20, dep_max_files default 5000→1000 to match code-level CBM_DEFAULT_AUTO_DEP_LIMIT and CBM_DEFAULT_DEP_MAX_FILES. Fixed: hint message provides complete commands, not fragments.

Fix: heap-allocate all three arrays with calloc, free on every return path. Verified: autorun repo (311 files, 6766 nodes) completes in 409ms. Also fix: main.c shutdown order — join autoindex thread BEFORE freeing watcher and watch_store.

charset=UTF-8 Content-Transfer-Encoding: 8bit Previous behavior: search_graph accepted qn_pattern, relationship, exclude_entry_points, include_connected, and include_dependencies in its JSON schema but never extracted or applied them — all 5 were silently ignored. trace_call_path hardcoded edge_types=["CALLS"] regardless of user input, and its compact default (true) disagreed with the schema (false). include_dependencies schema default was false, opposite to the prefix-match behavior that already included dep sub-projects by default. What changed: - src/mcp/mcp.c: extract qn_pattern and relationship in handle_search_graph Phase 1 (after name_pattern, before file_pattern); extract exclude_entry_points, include_connected, include_dependencies as bools after max_degree; wire all 5 into cbm_search_params_t; add include_dependencies=false guard: sets project_exact=true when project is set without glob pattern, scoping results to exact project name (excludes .dep.* sub-projects); add free(qn_pattern) and free(relationship) to cleanup block - src/mcp/mcp.c: replace hardcoded edge_types[]={"CALLS"} in handle_trace_call_path with user-supplied edge_types array extracted after all three early-return guards (lines 2062, 2069, 2086) to avoid memory leaks on those paths; use free_string_array() for cleanup; fix compact default from false to true (matches schema); fix include_dependencies schema default from false to true with updated description - src/store/store.c: add qn_pattern REGEXP/iregexp dual-branch WHERE clause after name_pattern block (same pattern as name_pattern at lines 1835-1844); add relationship EXISTS filter using local rel_cond[128] (exceeds bind_buf[64]) with both edge directions (source OR target); merge exclude_entry_points "in_deg > 0" condition into the existing degree-filter subquery block to avoid double subquery nesting; fix has_degree_wrap to include exclude_entry_points so ORDER BY uses bare column names in the outer wrapped query - tests/test_token_reduction.c: add setup_sp_server() fixture (4 nodes: main, process_request, fetch_data, dep_helper; 2 edges: CALLS main->process_request, HTTP_CALLS fetch_data->process_request); add 12 new parameterization accuracy tests in token_reduction suite covering qn_pattern filter, relationship filter, exclude_entry_points, include_dependencies=true/false, compact default, edge_types traversal Why: parameters declared in the MCP schema but not implemented silently accept user input and return wrong results — AI agents and users passing these params get misleading output. The include_dependencies schema default disagreed with actual behavior. The trace edge_types hardcoding prevented traversal of non-CALLS relationships (HTTP_CALLS, IMPORTS, etc.). Testable: make -f Makefile.cbm test (2213 passed, 0 failed) search_graph '{"qn_pattern":".*handlers.*","project":"sp-test"}' returns only handlers search_graph '{"relationship":"HTTP_CALLS","project":"sp-test"}' returns nodes with HTTP edges search_graph '{"exclude_entry_points":true}' removes nodes with in_deg=0 (CALLS) search_graph '{"include_dependencies":false,"project":"myapp"}' excludes myapp.dep.* nodes trace_call_path '{"function_name":"f","edge_types":["HTTP_CALLS"]}' follows HTTP edges --- src/mcp/mcp.c | 40 +++- src/store/store.c | 58 +++-- tests/test_token_reduction.c | 410 +++++++++++++++++++++++++++++++++++ 3 files changed, 490 insertions(+), 18 deletions(-) diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 7e130145..fcc93931 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -297,9 +297,9 @@ static const tool_def_t TOOLS[] = { "file.

Separated free from the watcher call; now always frees after successful cbm_store_get_project. - mcp.c handle_index_status: cbm_store_search_free skipped when dep_out.count==0 — cbm_store_search allocates even for empty results. Restructured to free whenever search succeeds. Same fix for cbm_project_free_fields call in ecosystem detection path. - pagerank.c: node_labels leaked on two early return paths (N==0 and id_map_init failure). Both paths now free node_ids and node_labels (with per-element free for strdup'd entries before the N==0 branch assigns any). - pass_envscan.c: 8 static regexes compiled once by compile_patterns() were never freed. Added cbm_envscan_free_patterns() that calls cbm_regfree on each and resets patterns_compiled=0. - pipeline.h/pipeline.c: public cbm_pipeline_global_cleanup() wraps cbm_envscan_free_patterns(). Called in main.c after ALL server threads joined (HTTP + stdio) to avoid racing with autoindex threads. Also called in run_cli() path and test_pipeline.c teardown. Ecosystem detection expanded from 8 to 17 package managers: - depindex.h: added CBM_PKG_MAKE, CBM_PKG_CMAKE, CBM_PKG_MESON, CBM_PKG_CONAN (C/C++ build systems). Expanded CBM_MANIFEST_FILES with build.gradle.kts, bun.lockb, global.json, Directory.Build.props, NuGet.Config, Makefile, GNUmakefile, Makefile.cbm, CMakeLists.txt, meson.build, conanfile.txt, conanfile.py, vcpkg.json. - depindex.c: rewrote cbm_detect_ecosystem to cover all 17 managers using CHECK() macro for exact filename matches and dir_contains_suffix() for wildcard patterns (*.csproj, *.fsproj). Added has_vendored_deps_dir() helper. Added discover_vendored_deps() which scans vendor/ vendored/ third_party/ thirdparty/ deps/ external/ ext/ contrib/ lib/ _vendor/ submodules/ for C/C++ and CBM_PKG_CUSTOM build systems. dep search hint in handle_search_graph: - When a dep project search (project:"dep", expanded to prefix ".dep") returns 0 results, emits a "hint" field with an ecosystem-aware actionable message. If cbm_detect_ecosystem succeeds, the hint names the detected build system and instructs to re-run index_repository. If no ecosystem detected, lists all 17 supported manifest file types. Compact output improvements in mcp.c: - handle_search_graph: skip emitting "name" when it equals the last segment of qualified_name (ends_with_segment check) or when empty. - handle_trace_call_path: same fix for both outbound (callees) and inbound (callers) node arrays. Added callers_total emission to match callees_total (was documented in tool description but never emitted). - build_snippet_response: skip empty name, label, and file_path fields. Compact param now wired through all six call sites in handle_get_code. Zero-value numeric fields skipped in compact mode. - handle_get_architecture / build_resource_architecture: skip redundant name (when equals last qualified_name segment) and empty label/fp in key_functions arrays. Test coverage: - test_token_reduction.c: 504-line new file covering compact suppression of redundant name/label/empty fields, callers_total presence, get_code compact param propagation, architecture key_functions, and dep search hint emission. - test_mcp.c, test_pipeline.c: minor additions for new behaviors. Makefile.cbm: - Added nosan build (CFLAGS_NOSAN, LDFLAGS_NOSAN, MONGOOSE_CFLAGS_NOSAN, per-object NOSAN variants for sqlite3/lsp/grammar/ts_runtime/mongoose). - Added test-leak target: macOS uses leaks --atExit on test-runner-nosan; Linux uses ASAN_OPTIONS=detect_leaks=1 on regular test-runner. - Added test-analyze target: Clang --analyze on production + test sources (skipped with message when IS_GCC=yes). - Updated .PHONY with test-leak, test-analyze, test-runner-nosan. --- Makefile.cbm | 105 ++++++- src/depindex/depindex.c | 188 ++++++++++-- src/depindex/depindex.h | 45 +-- src/main.c | 8 + src/mcp/mcp.c | 210 ++++++++----- src/pagerank/pagerank.c | 14 +- src/pipeline/pass_envscan.c | 15 + src/pipeline/pipeline.c | 8 + src/pipeline/pipeline.h | 6 + src/pipeline/pipeline_internal.h | 5 + tests/test_mcp.c | 38 ++- tests/test_pipeline.c | 3 + tests/test_token_reduction.c | 504 +++++++++++++++++++++++++++++++ 13 files changed, 1022 insertions(+), 127 deletions(-) diff --git a/Makefile.cbm b/Makefile.cbm index 933a51b7..dd684fb6 100644 --- a/Makefile.cbm +++ b/Makefile.cbm @@ -118,6 +118,9 @@ endif LDFLAGS = -lm -lstdc++ -lpthread -lz $(LIBGIT2_LIBS) $(WIN32_LIBS) LDFLAGS_TEST = -lm -lstdc++ -lpthread -lz $(SANITIZE) $(LIBGIT2_LIBS) $(WIN32_LIBS) LDFLAGS_TSAN = -lm -lstdc++ -lpthread -lz -fsanitize=thread $(LIBGIT2_LIBS) $(WIN32_LIBS) +# nosan: no ASan/UBSan — required for macOS 'leaks' tool (incompatible with ASan malloc replacement) +CFLAGS_NOSAN = $(CFLAGS_COMMON) -g -O1 +LDFLAGS_NOSAN = -lm -lstdc++ -lpthread -lz $(LIBGIT2_LIBS) $(WIN32_LIBS) # ── Source files ───────────────────────────────────────────────── @@ -236,8 +239,9 @@ UI_SRCS = \ # Mongoose HTTP library (vendored, compiled with relaxed warnings) MONGOOSE_SRC = vendored/mongoose/mongoose.c MONGOOSE_CFLAGS = -std=c11 -D_DEFAULT_SOURCE -O2 -w -Ivendored -DMG_ENABLE_LOG=0 -MONGOOSE_CFLAGS_TEST = -std=c11 -D_DEFAULT_SOURCE -g -O1 -w -Ivendored -DMG_ENABLE_LOG=0 \ - $(SANITIZE) +MONGOOSE_CFLAGS_TEST = -std=c11 -D_DEFAULT_SOURCE -g -O1 -w -Ivendored -DMG_ENABLE_LOG=0 \ + $(SANITIZE) +MONGOOSE_CFLAGS_NOSAN = -std=c11 -D_DEFAULT_SOURCE -g -O1 -w -Ivendored -DMG_ENABLE_LOG=0 # mimalloc (vendored, global allocator override) MIMALLOC_SRC = vendored/mimalloc/src/static.c @@ -357,7 +361,7 @@ PP_OBJ_TEST = $(BUILD_DIR)/preprocessor.o # ── Targets ────────────────────────────────────────────────────── -.PHONY: test test-foundation test-tsan cbm cbm-with-ui frontend embed clean-c lint lint-tidy lint-cppcheck lint-format install +.PHONY: test test-foundation test-tsan test-leak test-analyze cbm cbm-with-ui frontend embed clean-c lint lint-tidy lint-cppcheck lint-format install test-runner-nosan $(BUILD_DIR): mkdir -p $(BUILD_DIR) @@ -430,7 +434,62 @@ $(BUILD_DIR)/prod_tre.o: $(TRE_SRC) | $(BUILD_DIR) $(CC) $(TRE_CFLAGS) -O2 -c -o $@ $< endif -OBJS_VENDORED_TEST = $(MIMALLOC_OBJ_TEST) $(SQLITE3_OBJ_TEST) $(TRE_OBJ_TEST) $(GRAMMAR_OBJS_TEST) $(TS_RUNTIME_OBJ_TEST) $(LSP_OBJ_TEST) $(PP_OBJ_TEST) $(MONGOOSE_OBJ_TEST) +OBJS_VENDORED_TEST = $(MIMALLOC_OBJ_TEST) $(SQLITE3_OBJ_TEST) $(TRE_OBJ_TEST) $(GRAMMAR_OBJS_TEST) $(TS_RUNTIME_OBJ_TEST) $(LSP_OBJ_TEST) $(PP_OBJ_TEST) $(MONGOOSE_OBJ_TEST) + +# ── Nosan build: ASan-free test runner for macOS heap leak detection ───────── +# +# WHY THIS EXISTS: +# 'make test-leak' uses Apple's 'leaks --atExit' tool to find heap leaks. +# But leaks cannot inspect a process that uses a custom malloc (such as ASan). +# The regular test-runner is built with -fsanitize=address,undefined, which +# replaces malloc → leaks aborts with "unable to inspect heap ranges". +# +# HOW IT WORKS: +# We rebuild all ASan-instrumented vendored objects without -fsanitize flags +# into $(NOSAN_DIR), then link test-runner-nosan against them. +# The resulting binary runs the full test suite under Apple's heap profiler. +# Full leak report is written to $(LEAK_LOG) = build/c/leak-report.txt. +# +# HOW TO USE: +# make test-leak # runs full suite + heap check, saves report to LEAK_LOG +# cat build/c/leak-report.txt # review complete leak report after run +# +# WHICH OBJECTS NEED NOSAN VARIANTS (use SANITIZE in their *_TEST flags): +# sqlite3, lsp_all, preprocessor, grammar/*.c, ts_runtime, mongoose +# WHICH ARE REUSED AS-IS (never use SANITIZE): +# mimalloc (MIMALLOC_CFLAGS_TEST has no -fsanitize) +# tre (only on Windows;

charset=UTF-8 Content-Transfer-Encoding: 8bit CLAUDE.md (new): project-level developer notes for Claude with concrete commands for make test, make test-leak, make test-analyze, and explanation of why macOS requires test-runner-nosan (ASan replaces malloc, blocking leaks --atExit from walking the heap). CONTRIBUTING.md: added "Run C Server Tests" section after the Go test section. Covers make -f Makefile.cbm test/test-leak/test-analyze, the macOS vs Linux difference in leak detection approach, and the expected clean-run output ("0 leaks for 0 total leaked bytes").

O(M+F) runtime. pipeline.c: normalize pass before dump. Makefile.cbm updated. Phase 7 — CBMLangSpec section_node_types field: lang_specs.h: added section_node_types (17th field) lang_specs.c: all 64 language specs updated with NULL initializer Phase 8 — IX-1..3 indexing pathway fixes: mcp.c: autoindex_failed + just_autoindexed flags in server struct, REQUIRE_STORE captures pipeline return code, build_resource_status shows "indexing" state + failure detail + action_required hints Additional fixes: G1: summary mode adds results=[] + results_suppressed=true CQ-3: Cypher + filter params produces warning Tests: 2238 pass (11 new in test_input_validation.c covering F1,F6,F9, F10,F15 edge cases, G1, CQ-3, IX-2).

charset=UTF-8 Content-Transfer-Encoding: 8bit Previous behavior: autotune set config keys but never triggered PageRank recompute between experiments — all experiments read stale stored scores, producing identical results. The binary also got SIGKILL'd on macOS 25+ due to invalidated ad-hoc signature after `cp` during install. What changed: - scripts/autotune.py: replace query_architecture() (async REQUIRE_STORE reindex) with index_and_query_architecture() — opens one persistent stdio MCP session per repo per experiment sending 3 sequential messages: initialize → tools/call index_repository (synchronous, blocks until full pipeline+PageRank completes with current edge weights) → resources/read codebase://architecture - scripts/autotune.py: add project_name_from_path() mirroring cbm_project_name_from_path() from src/pipeline/fqn.c, and delete_project_db() to remove stale DBs - scripts/autotune.py: add _send_batch() env+cwd params; pass CBM_TOOL_MODE=classic so index_repository tool is available in MCP session - scripts/autotune.py: add --top-matches (default 10) and --key-count (default 25) CLI params; show matched expected names + top-N per repo in output - scripts/autotune.py: default timeout 60s → 1200s (indexing takes ~40s per repo) - scripts/autotune.py: add exclude_ui_tests experiment; rename calls_boost_excl → calls_boost_excl_tests with tests/** added to exclude list - scripts/autotune.py: save every run to scripts/autotune_results.json (appended, with timestamp/binary/repos/experiments/best fields) - scripts/autotune.py: show progress bar (█/░) and ◀ BEST marker in final report - .gitignore: add scripts/autotune_results.json (generated artifact, not tracked) Why: edge weights and PageRank iterations are only applied at index time via cbm_pagerank_compute_with_config(); querying a DB indexed with old weights produces wrong rankings regardless of config changes. Full reindex per experiment is required. Also fixes macOS 25+ SIGKILL by rebuilding binary (Makefile.cbm re-signs with codesign --force --sign - after install). First run result: calls_boost_excl_tests scores 6/30 (best), baseline 0/30.

What changed: - scripts/autotune.py DEFAULTS: edge_weight_calls 1.0 → 2.0 (call edges are the strongest signal for production importance) - scripts/autotune.py DEFAULTS: edge_weight_usage 0.7 → 0.3 (type-reference edges add noise, dampening improves ranking signal) - scripts/autotune.py DEFAULTS: key_functions_exclude "" → "graph-ui/**, tools/**,scripts/**,tests/**" (excluding non-production paths surfaces core library functions instead of test helpers) Why: autotune run on 2026-03-26 scored calls_boost_excl_tests at 6/30 across 3 repos (codebase-memory-mcp, autorun, rtk), best of 8 experiments. Baseline scored 0/30. These defaults are now the baseline that experiments diverge from, so future autotune runs search the config space around the current best.
