ContextAtlas

Run ContextAtlas extraction inside Claude Code session (subscription-bounded; no Anthropic API key needed). Walks ADRs + source-symbol docstrings + filtered commit messages via `contextatlas list-extraction-sources` and extracts architectural claims via per-source iteration discipline. Persists to .contextatlas/atlas.json (committable artifact); LSP symbol resolution via mandatory `contextatlas resolve-symbols` post-extraction; canonical Claude Code entry point per ADR-02 v0.7 amendment §Decision entry-point-determined cost model. Substrate-equivalence with CLI extraction path closed at v0.7.1 ADR-02 amendment §index-atlas substrate-equivalence closure.

Prime your Claude Code session with ContextAtlas tools substrate at the start of each session in a ContextAtlas-configured repo. Verifies the MCP connection by probing the atlas + introduces the three MCP tools (get_symbol_context, find_by_intent, impact_of_change) with when-to-use guidance. Run this once per session before architectural work that would benefit from ContextAtlas's fused symbol + ADR + git + tests bundles per ADR-02 query-time-no-API-calls invariant.

Generate Architectural Decision Records (ADRs) for a codebase by walking the source tree, identifying non-obvious architectural decisions, and writing canonical ContextAtlas-format ADRs to docs/adr/. Runs inside Claude Code session (subscription-bounded; no Anthropic API key needed). Supports optional --reference-context for migrating from heterogeneous existing documentation (Django DEPs, Confluence exports, internal wikis, RFC repos). Canonical Claude Code entry point per ADR-02 v0.7 amendment §Decision entry-point-determined cost model.
