Claude Code Codebase Intelligence

repowise has released an open-source codebase intelligence layer for Claude Code. A single pip install provides 9 MCP tools, and it indexes the codebase into 5 layers.

• Graph: Parses 14 languages with tree-sitter to build a dependency graph, and uses community detection and PageRank to find modules and central code.
• Git: Calculates hotspot, ownership, co-change pairs, bus factor, and module health scores.
• Docs: Automatically generates wikis per module and file, incrementally updates them with every commit, and provides semantic search and freshness scoring.
• Decisions: Extracts architectural decisions from git history and inline markers, links them to code, and allows lookup via get_why().
• Code Health: Scores 12 deterministic biomarkers per file on a 1-10 scale, and supports coverage report ingest, trend tracking, and regression alerts.

In benchmarks (Flask, claude-sonnet-4-6, 48 tasks), it showed 36% cheaper, 49% fewer tool calls, and 89% fewer file reads.
