Arc PRD to Issues

Convert a PRD into GitHub issues. The leading word is tracer-bullet: each issue is a narrow, end-to-end vertical slice, not a horizontal layer.

For slice rules and issue template, load SLICE_FORMAT.md. For GitHub creation commands, load GITHUB_CREATION.md after the user approves the slice breakdown.

Steps

1. Locate the PRD.

   • Use an explicit issue number, URL, file path, or pasted PRD.
   • If missing, ask for the PRD source.
   • Fetch GitHub PRDs with comments when relevant.

   Completion criterion: the PRD content is available, or the run stops with a source request.

2. Explore current code where useful.

   • Read enough repo structure and existing implementation to avoid impossible or duplicate slices.
   • Keep this lightweight when the PRD is greenfield.

   Completion criterion: slices reflect current repo reality or state that repo context is unknown.
