From 0693d08edd5d6801616fbacd29c83b6415de7856 Mon Sep 17 00:00:00 2001 From: Andrew Hundt Date: Fri, 20 Mar 2026 00:08:16 -0400 Subject: [PATCH] mcp: add index_dependencies tool + AI grounding infrastructure MIME-Version: 1.0 Content-Type: text/plain; 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.
