Bug Hunting¶

Find reproducible bugs and automatically fix them.

Bug Hunter finds user-impacting bugs by reviewing recent git history, writing minimal reproduction scripts, and filing a report issue only when the bug is concretely confirmed. Chain it to Create PR from Issue for a fully autonomous detect-and-fix loop. Most runs end with noop.

Quick install¶

Detector only¶

Install Bug Hunter alone if you want to review bug reports before acting on them.

mkdir -p .github/workflows && curl -fsSL \
  https://raw.githubusercontent.com/elastic/ai-github-actions/v0/gh-agent-workflows/bug-hunter/example.yml \
  -o .github/workflows/bug-hunter.yml

Chained (detector + fixer)¶

Install the chained example for a fully autonomous bug-finding and fixing pipeline.

mkdir -p .github/workflows && curl -fsSL \
  https://raw.githubusercontent.com/elastic/ai-github-actions/v0/gh-agent-workflows/bug-hunter/example-chained.yml \
  -o .github/workflows/bug-hunt-and-fix.yml

Bug Hunter (detector)¶

Reviews 28 days of git history for user-facing changes that could introduce bugs. For each candidate, writes a new minimal reproduction script and runs it — filing a report only when the bug is concretely confirmed.
