Four layers of team intelligence

Coauthor goes beyond line counts. Every analysis layer builds on git history to produce insights that reflect how your team actually works.

Git History Analysis

Full commit graph traversal. Understands merges, rebases, and squashes. Works with any git repository.

Structural Impact Scoring

Every commit gets an impact score based on cross-file dependencies, not just lines changed. A one-line architectural change scores higher than a 500-line rename.

Pattern Classification

Contributors are classified as specialists (deep in one area), generalists (broad coverage), hubs (connect modules), or peripheral (occasional touches). Based on commit topology, not labels.

Knowledge Concentration

Bus factor analysis at module, subsystem, and repo level. Identifies where knowledge is concentrated and where it's distributed.

MCP Tools

10 tools for your AI assistant

Add Coauthor as an MCP server and ask your AI assistant about code ownership, impact, and team patterns in natural language.

coauthor_who_owns

The killer tool. Ask who owns any file, module, or subsystem. Returns structural ownership with confidence scores.

coauthor_impact_score

Score any commit or PR by structural impact. Distinguish config changes from architectural decisions.

coauthor_team_patterns

Classify team members by contribution pattern. Identify specialists, generalists, hubs, and peripheral contributors.

coauthor_knowledge_map

Map knowledge distribution across the codebase. Find concentration risks and coverage gaps.

coauthor_hot_spots

Find the most actively changed files and who's changing them. Churn analysis with ownership context.

coauthor_review_load

Analyze code review patterns. Who reviews what, review latency, and review coverage.

Dashboard

6 views, dark theme, zero config

Self-hosted web dashboard with authorship visualizations. Runs locally, auto-syncs from git analysis. Dark theme with amber accent.

Ownership Map

Codebase tree colored by primary owner. Click any file or directory to see authorship breakdown.

Team Patterns

Contributor classification grid. See specialists, generalists, hubs, and peripheral at a glance.

Impact Timeline

Structural impact of commits over time. Spot architectural shifts and high-impact periods.

Knowledge Heat Map

Bus factor visualization. Red = single owner, green = distributed knowledge.

Contributor Profiles

Per-person view of areas of expertise, impact history, and collaboration patterns.
