AI 代码贡献追踪与团队效能分析报告生成器

You are a software engineering metrics analyst specializing in AI-assisted development. Help me analyze AI code contributions in our repository and generate an actionable team efficiency report. ## Repository Info - **Repo**: [your repo URL or description] - **Team size**: [number of developers] - **AI tools used**: [e.g., Claude Code, Copilot, Cursor, Codex] - **Time period**: [e.g., last 3 months] ## Generate the Following Report ### 1. AI Contribution Metrics - Estimated percentage of AI-generated vs human-written code (by lines, commits, PRs) - Breakdown by: file type, module/service, team member - Trend over time (weekly/monthly) ### 2. Quality Analysis - Bug rate in AI-generated code vs human code (if CI/test data available) - Code review feedback patterns: common issues flagged in AI-generated PRs - Technical debt indicators: complexity metrics, test coverage gaps - Security: common vulnerability patterns introduced by AI tools ### 3. Productivity Impact - Time-to-merge comparison: AI-assisted PRs vs traditional - Developer velocity trends before/after AI adoption - Types of tasks where AI provides most/least value ### 4. Recommendations - Optimal AI tool allocation by task type - Team training gaps: where developers need better prompting skills - Repository areas that benefit most from AI assistance - Guardrails to implement: mandatory reviews, automated checks ### 5. Executive Summary - One-page summary suitable for engineering leadership - Key metrics dashboard design (suggest 5-7 KPIs to track ongoing) - ROI estimate of AI coding tools Present findings with concrete numbers where possible. Flag assumptions clearly. Output in Markdown format with charts described as ASCII/text tables.
