codegraph-cli

Supporting utility skill (Layer 11 Meta · "Code Reading Tools" pair with gitnexus-repo-map). Wraps the CodeGraph CLI (npm i -g @colbymchenry/codegraph · cli codegraph) so the harness can use it for fast local symbol traversal and affected-test selection without bolting an MCP server onto Claude Code by default.

1. Purpose

CodeGraph parses a repo with tree-sitter, stores symbols + edges + files in a local SQLite (FTS5) at .codegraph/codegraph.db, and exposes a CLI that lets you ask precise questions about the local code:

• "Who calls this function?"
• "What does this function call?"
• "If I change this symbol, what is affected?"
• "For this task description, what is the minimum context I need?"
• "Given this git diff, which test files should I run?"

This skill uses only the CLI surface. CodeGraph also ships an MCP server (codegraph serve --mcp) and a multi-agent installer (codegraph install) that registers itself in ~/.claude.json, ~/.cursor/, ~/.codex/, ~/.config/opencode/, etc. The harness does not auto-enable any of that — the harness already has its own MCP and orchestrator topology; we use CodeGraph as a knife, not as a daemon.
