Contextatlas
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.

get_symbol_contextThe primitive: given a known symbol, returns the full fused bundle (signature, ADR claims, references, git heat, tests, types) in a single call.

find_by_intentThe semantic-query composite: finds symbols by what they do, ranking by BM25 against indexed claim text in local SQLite FTS5.

impact_of_changeThe blast-radius composite: adds git co-change patterns and test impact on top of the primitive to show what breaks when a symbol changes.

ContextAtlas
Stop watching Claude burn tokens grepping for context it can't possibly find.
ContextAtlas turns your codebase into a single-call context bundle for Claude Code — fusing LSP-grade structure, architectural intent from your Architectural Decision Records (ADRs), git history, and test associations. Measured 45-72% token reduction with zero quality regression across benchmark axes on architectural prompts across the hono / httpx / cobra benchmark suite.
