what-iff: Skill for Claude Code

File a GitHub pull request (public repo only)

Everything here is world-readable forever. No internal hostnames, customer names, private-repo paths, Jira keys, Notion links, or session URLs in the title or body — and no Generated with/Claude-Session style attribution.

1. Guard

REPO=$(gh repo view --json nameWithOwner -q .nameWithOwner)
[ "$REPO" = theimaginaryfoundation/what-iff ] || { echo "not the public repo ($REPO); stop"; exit 1; }
BRANCH=$(git branch --show-current)
[ "$BRANCH" != main ] || { echo "on main; create a feature branch first"; exit 1; }
case "$BRANCH" in *claude*) echo "branch name contains 'claude': $BRANCH"; exit 1;; esac

2. Dedupe

gh pr list --head "$BRANCH" --json number,url,state

If one is already open for this branch, report its URL instead of filing a second one.

3. Push and file

git push -u origin "$BRANCH"

Body sections must match the template headings exactly (## Summary, ## Test plan, ## Checklist) — same headings render the same and keep the diff against the template minimal for reviewers. Fill every checklist item you actually verified with [x]; leave the rest [ ], never delete them.

gh pr create -t "<summary, ≤72 chars, no trailing period>" -F - <<'BODY'
## Summary

- <what changed, in 1-3 bullets>

## Test plan

- [x] `make pre-commit`
- [ ] Frontend lint/test/build
- [x] Manually verified: <what you actually did>

## Checklist

- [x] No credentials, personal exports, generated local state, or production config committed
- [x] Public defaults still work without hosted services
- [ ] Updated architecture docs (only if this touches system boundaries)
- [ ] Regenerated the e2e SDK (only if `openapi.yaml` changed)
BODY

Report the URL gh prints. Only add -a @me, -l, --base, or -d (draft) if asked.

4. Fix in place

If the description turns out wrong or incomplete after further review, gh pr edit <N> -t/-F the original — never leave it standing and add a "correction" comment.
