GitHub Contribution Period Analysis

Core Goal

  • Build an evidence-based Markdown report for one target GitHub user in a UTC time window.
  • Focus on practical code contribution signals: merged PR and commit activity.
  • Cover both own repositories and other repositories, limited by credential access.

Workflow

  1. Prepare authentication for GitHub API access.
  2. Run scripts/githubcontributionreport.py with target user and time window.
  3. Review the generated Markdown report and inspect evidence links.

Command

python3 scripts/github_contribution_report.py \
  --user <github-login> \
  --start 2026-03-01 \
  --end 2026-03-08 \
  --output /tmp/github-contribution-report.md

Output Semantics

  • Included contribution types:

- Authored merged PRs. - PRs merged by the target user (maintainer merge work). - Authored commits.

  • Excluded activity types:

- Comments, reviews, stars, watches, forks.

  • The report contains:

- Scope and coverage notes. - Summary metrics. - Substantive work categories inferred from PR/commit evidence. - Work content highlights with representative evidence links. - Repository breakdown. - Per-repository concrete change details (for every changed repository). - Contribution timeline. - Top contribution tables. - Evidence appendix with PR/commit URLs.

Important Constraints

  • SSH key alone is for git transport and does not directly authorize GitHub REST API calls.
  • Private repository coverage needs authenticated API access, typically via GITHUBTOKEN/GHTOKEN or gh auth token.
  • GitHub Search API has a 1000-item cap per query. For very active users, split the time range and run multiple reports.
