codebase-exploration

Local-first codebase search and MCP context packs for coding agents — SQLite FTS5, tree-sitter symbol graphs, and reusable briefings.

A Claude Code skill for understanding an unfamiliar codebase fast — systematic exploration from entry points to data flow.

Integrates Microsoft's fastcontext tool directly into the pi coding agent. Allows for efficient, natural-language codebase searching without high context token consumption. Built with Node.js built-in modules only.

A zero-dependency, local, interactive call-graph navigator for Python codebases. One script in, one self-contained HTML file out

Ramp up on any new codebase in 2-3 days using GitHub Copilot. A reusable prompt-driven onboarding playbook with Mermaid diagrams.

Parse any codebase, build a knowledge graph, visualise it, and query it in natural language.

Preresearch hook for Claude Code — runs Haiku to explore your codebase before Opus/Sonnet so the main model can skip straight to implementation
