Create PR: Open the Pull Request, Hand Off for Review

This is the ship step of the PIV loop: the implementation is committed on a feature branch; now open the PR so it can be reviewed (by the piv-review-pr agentic gate, then a human).

Phase 0 — Detect the base branch

Don't hardcode main. Resolve it:

1. If $ARGUMENTS contains --base <branch>, use that.
2. Else: git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@'
3. Fallback: git remote show origin 2>/dev/null | grep 'HEAD branch' | awk '{print $NF}'
4. Last resort: main. Store as {base}.

Phase 1 — Validate git state

git branch --show-current
git status --short
git log origin/{base}..HEAD --oneline

State	Action
On {base}	STOP: "Create a feature branch first (the ticket should be on its own branch)."
Uncommitted changes	STOP: "Commit (or stash) before opening the PR."
No commits ahead of {base}	STOP: "Nothing to PR."
Existing PR for this branch (gh pr list --head $(git branch --show-current) --json url)	STOP and print the URL.
Clean, commits ahead, no PR	PROCEED

Phase 2 — Gather context for the body

• Project conventions: if .claude/references/conventions.md exists, read its ## pr section — its rules win over the default template below (sections, tone, what must be stated). That file is where a project's specifics live; this skill stays general.
• Commits: git log origin/{base}..HEAD --pretty=format:"- %s"
• Files: git diff --stat origin/{base}..HEAD
• Implementation report (if piv-implement wrote one — .claude/reports/<…>-report.md): pull the summary, validation results, and documented deviations (these belong in the PR body — they tell the reviewer what was intentional).
• Linked ticket / issue: look for ACC-…, #123, Fixes #… in the commits/branch name.
• PR template: if .github/PULL_REQUEST_TEMPLATE.md exists, fill it; else use the default below.

Phase 3 — Push and open the PR

git push -u origin HEAD

gh pr create --base "{base}" --title "{type}: {concise description}" --body "$(cat <<'EOF'
## Summary
{1-2 sentences: what this ticket delivers}

## What changed
{commit summaries}

## Validation
- Tests / type-check / lint: {pass/fail from the implementation report or a fresh run}
- Manual check: {what was exercised, or "pending review"}

## Notes for the reviewer
{documented deviations from the plan — intentional decisions — or "none"}

## Linked
{ticket / issue refs, or "none"}

_Ready for review._
EOF
)"

({type} = feat/fix/refactor/… from the work. Use --draft if the work isn't ready for a real review.)

Output

gh pr view --json number,url,title,baseRefName,headRefName

Report the PR number + URL, the base ← head branches, and "Ready for review → run piv-review-pr <number>, then a human approves." This is the handoff point: the agent's loop ends at an open PR; review and merge are the gates.

Notes

• Tool-agnostic in spirit: this skill uses GitHub (gh); the same motion is "open a merge request" on GitLab, or "mark ready for review" wherever your team works. Solo with no remote? Skip the PR — commit on {base} and review your own diff before moving on.
• Sets up parallel work: one branch per ticket → one PR per ticket is exactly what makes worktree parallelism (running independent tickets at once) clean.
