contributor-analyzer
Analyzes engineering contributors for annual reviews, progress tracking, and production ownership. Reads every commit diff (not sampling), calculates accuracy rates, assesses engineering maturity through qualitative judgment, and generates promotion-ready performance reviews. Works with any git repository using local git for commit analysis and gh CLI for GitHub PR/review metadata.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Contributor Analyzer Unified skill for engineering contributor analysis. Combines annual review generation, historical progress tracking, production ownership mapping, and qualitative judgment — all driven by reading actual commit diffs. ## Skill Format Each reference file covers one analysis concern: - **Quick Reference**: Summary tables and key thresholds - **Process Steps**: Bash commands and orchestration - **Templates**: Output formats for reports and profiles - **Deep Dive**: Full context with examples from real-world 1,091-commit analysis **Impact ratings**: CRITICAL (blocks accuracy), HIGH (major insight), MEDIUM (enriches analysis) ## When to Apply Reference these guidelines when: - Running annual or quarterly performance reviews - Assessing promotion readiness with evidence - Tracking contributor progress over time (incremental updates) - Mapping production code ownership and risk - Comparing multiple engineers for team decisions - Identifying single points of failure in codebase ownership ## Priority-Ordered References | Priority | Reference | Impact | Description | |----------|-----------|--------|-------------| | 1 | `agent-context-management.md` | CRITICAL | Batch s

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill contributor-analyzer-anivar-contributor-analyzer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
