• Activity heatmap data (GitHub-style)
• Per-project contribution breakdown

Compatible with dashforge static dashboards.

Contributor Profile

The contributor profile includes:

• User information (name, bio, location, etc.)
• Repository breakdown with contribution counts
• Language statistics
• Daily activity data for heatmap visualization
• Aggregate statistics (commits, PRs, issues, reviews)
• AI collaboration metrics (see below)

AI Collaboration Tracking

devfolio tracks AI-assisted development by detecting co-author signatures in commits. This measures how "AI-native" a developer is.

Supported AI Tools:

Tool	Detection Method	Status
Claude Code	Co-Authored-By: Claude <noreply@anthropic.com>	Recognized by GitHub
GitHub Copilot	Co-Authored-By: ... <noreply@github.com>	Recognized by GitHub
Gemini CLI	Co-Authored-By: gemini-cli ... <218195315+gemini-cli@users.noreply.github.com>	Recognized by GitHub
Cursor	Co-Authored-By: ... <ai@cursor.sh>	Detection via message parsing
Aider	Co-Authored-By: ... <aider@aider.chat>	Detection via message parsing

All tools are detected by parsing commit messages for Co-Authored-By: trailers.

AI Stats Output:

{
  "aiStats": {
    "totalAiCommits": 42,
    "aiCommitPercent": 23.5,
    "byTool": {
      "Claude Code": {
        "name": "Claude Code",
        "commits": 35,
        "firstUsed": "2024-06-15",
        "lastUsed": "2025-02-26",
        "recognized": true
      }
    },
    "mostUsedTool": "Claude Code",
    "firstAiCommit": "2024-06-15",
    "aiActivity": [
      {"date": "2025-02-25", "count": 3},
      {"date": "2025-02-26", "count": 5}
    ]
  }
}

This data can be used to:

• Showcase AI-native development practices in portfolios
• Track adoption of AI tools across a team
• Measure productivity impact of AI assistance
