Git Impact Analyzer

Git Impact Analyzer is a local CLI for estimating product impact from merged GitHub PRs and analytics data available through OneQuery.

It runs a phased workflow:

1. Check configured OneQuery sources.
2. Collect PR, tag, release, and changed-file data from GitHub.
3. Link PRs to deployment markers and feature groups.
4. Score impact from bounded before/after analytics windows.
5. Render an interactive report.

Example

Usage

./git-impact analyze --since 2026-04-01

Other scopes:

./git-impact analyze --pr 6054
./git-impact analyze --feature "creator_feature_request_button"
./git-impact check-sources

For machine-readable output:

./git-impact --output json analyze --since 2026-04-01

Configuration

The CLI reads impact-analyzer.yaml by default:

onequery:
  org: onequery-demo
  github_repository: owner/repo
  sources:
    github: github-source-key
    analytics: analytics-source-key
analysis:
  before_window_days: 7
  after_window_days: 7
  cooldown_hours: 0

Use --config to point at another file.

Development

go test ./internal/gitimpact ./internal/wtl ./cmd/git-impact

The repo-root ./git-impact script runs go run ./cmd/git-impact.
