{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What is repowise?","acceptedAnswer":{"@type":"Answer","text":"repowise is a codebase intelligence layer for the AI era. It indexes your repo once and serves both your AI coding agents (an architecture-aware wiki, dependency graph, decisions, and nine MCP tools) and the humans accountable for the code (a defect-validated code-health score, change risk, git intelligence, and agent provenance). It is open source and self-hostable."}},{"@type":"Question","name":"Is repowise free and open source?","acceptedAnswer":{"@type":"Answer","text":"Yes. The core engine is open source under AGPL-3.0 and runs 100% locally: pip install repowise, bring your own API key, or run fully offline with a local model. There are paid hosted tiers for teams that want zero-ops hosting, private-repo PR comments, and managed re-indexing."}},{"@type":"Question","name":"Which AI agents and editors does it work with?","acceptedAnswer":{"@type":"Answer","text":"repowise exposes your codebase over the Model Context Protocol, so it works with Claude Code, Cursor, Cline, and Codex, plus any other MCP-compatible client. One index serves every agent."}},{"@type":"Question","name":"How much does repowise reduce my agent's token usage?","acceptedAnswer":{"@type":"Answer","text":"On paired benchmarks on real repositories, loading context through repowise used 96% fewer tokens (2,391 vs 64,039, about 27 times fewer), with 89% fewer file reads and 70% fewer tool calls, at answer quality on par with raw file exploration."}},{"@type":"Question","name":"Does my source code leave my machine?","acceptedAnswer":{"@type":"Answer","text":"No. repowise is self-hosted with zero telemetry. Source is processed transiently and never persisted, and you can bring your own LLM key or run fully offline via a local model. What is stored is the graph, non-reversible embeddings, generated wiki pages, and git metadata."}},{"@type":"Question","name":"Does the code-health score actually predict bugs?","acceptedAnswer":{"@type":"Answer","text":"Yes, and it is validated. Across 21 repos and 9 languages the cross-project ROC AUC is 0.74 (up to 0.90 per repo), and ranking by repowise health surfaces 2.3x the defects of a leading commercial tool under the same review budget. Every heuristic is open source so you can reproduce it on your own repo."}},{"@type":"Question","name":"Which languages are supported?","acceptedAnswer":{"@type":"Answer","text":"Fifteen languages across the headline tiers, with full pipeline depth for Python, TypeScript, JavaScript, Java, Kotlin, Go, Rust, C++, and C#, including framework-aware route-to-handler edges for the major web frameworks."}},{"@type":"Question","name":"How does repowise stay up to date as I keep committing?","acceptedAnswer":{"@type":"Answer","text":"It updates incrementally. A post-commit hook, file watcher, or webhook re-indexes only what changed, typically a handful of wiki pages in seconds, and every MCP response carries a staleness envelope that warns when the index has diverged from HEAD."}},{"@type":"Question","name":"What is the difference between repowise and CodeScene?","acceptedAnswer":{"@type":"Answer","text":"repowise is an open-source (AGPL-3.0) alternative to CodeScene. Both analyze git history for hotspots and code health, but repowise adds a defect-validated health score (ROC AUC 0.74 across 21 repos), an LLM-generated architecture wiki, nine MCP tools for AI agents, and dead code detection. repowise is self-hostable at no cost; CodeScene is closed-source and enterprise-priced."}},{"@type":"Question","name":"How do I generate a CLAUDE.md file for my repository?","acceptedAnswer":{"@type":"Answer","text":"Run 'repowise init' in your project root. repowise indexes the repo's AST, dependency graph, git history, and architecture, then generates a CLAUDE.md file that gives Claude Code, Cursor, and other AI coding agents immediate orientation: tech stack, entry points, hotspot files, ownership, and key design decisions. The file updates incrementally on every commit."}},{"@type":"Question","name":"What is git hotspot analysis?","acceptedAnswer":{"@type":"Answer","text":"Git hotspot analysis identifies files that are both frequently changed (high churn) and structurally complex. The intersection of churn and complexity marks the files most likely to contain defects and be expensive to modify. repowise computes hotspots from commit history and displays them with health scores, owner attribution, and blast-radius estimates."}}]}
