Coauthor
Understand who built what
and how work flows through your team
Coauthor analyzes your git history to map ownership, measure structural impact, and classify team patterns. Ask "who owns this module?" and get an answer grounded in commit topology, not guesswork.
Get started
From install to insight in four steps
Install Coauthor
pip install or clone from GitHub. One command, no account required.
Add the MCP server
Point Claude Code at Coauthor's MCP config. Takes 30 seconds.
Ask who owns what
"Who owns the authentication module?" -- Coauthor analyzes git history and returns structural ownership, not just line counts.
Understand your team
Impact scoring, pattern classification (specialist, generalist, hub, peripheral), and knowledge concentration -- all from git.
Capabilities
What Coauthor does
Structural Ownership
Goes beyond line counts. Analyzes commit patterns, structural changes, and architectural impact to determine who truly owns each part of the codebase.
10 MCP Tools
who_owns, impact_score, team_patterns, knowledge_map -- all available as MCP tools your AI assistant can call directly from your editor.
Pattern Classification
Automatically classifies contributors as specialists, generalists, hubs, or peripheral based on their commit topology -- not arbitrary labels.
Impact Scoring
Every commit gets a structural impact score. Distinguish a one-line config change from a one-line architectural decision that affects 50 files.
Knowledge Concentration
Identify bus factor risks before they become incidents. See where knowledge concentrates and where it's distributed across the team.
Dashboard
Dark-themed web dashboard with authorship visualizations, team pattern views, and ownership maps. Auto-syncs from git analysis.
Analysis
Four layers of team intelligence
Git History Analysis
Commit topology, blame, authorship
Structural Impact
Cross-file dependencies, architectural changes
Team Patterns
Specialist, generalist, hub, peripheral
Knowledge Maps
Concentration, distribution, bus factor
