LLM Wiki for Codebases

Build a persistent, interlinked markdown wiki that captures the architecture, modules, patterns, and APIs of a codebase. The wiki lives in .llm-wiki/ at the project root. Humans curate and direct; the LLM handles all bookkeeping.

Based on Andrej Karpathy's LLM Wiki pattern: raw sources are "compiled" into a structured wiki that compounds over time.

Mode Detection

Determine the mode based on current state:

• No .llm-wiki/ directory exists -> Full Build mode
• .llm-wiki/ exists -> Update mode (diff and refresh)

Full Build Workflow

Phase 1: Reconnaissance

1. Read top-level files: README, package.json/Cargo.toml/go.mod/pyproject.toml/build.gradle etc.
2. Run find or Glob to map the directory tree (ignore node_modules, .git, vendor, dist, build, pycache, .venv)
