If you're tired of watching Claude burn 40+ tool calls and 100k tokens grep-crawling for architectural context it can't retain between sessions, ContextAtlas pre-indexes your codebase into single-call bundles. It fuses LSP symbol data with extracted ADR claims, git history, and test associations, so when Claude asks about OrderProcessor it gets the structure, the "must be idempotent" constraint from your design docs, recent commits, and test coverage in one shot instead of fifteen. The developer benchmarked this on hono, httpx, and cobra at 45-72% token reduction on architectural prompts with no quality regression. You get value even without ADRs since LSP plus git plus tests in one call beats the baseline, but the real win is surfacing design intent before Claude proposes changes that violate it. Ships as both CLI and MCP server generating the same atlas.json artifact.
