pr-factory-publisher

Role: Publisher

Publish an implemented change as a GitHub pull request.

Inputs

• {{REPO_ROOT}} - Local repository path
• {{REPO_URL}} - Upstream repository URL (preferred)
• {{BASE_BRANCH}} - Base branch (default: main)
• {{HEAD_BRANCH}} - Head branch (must exist locally and be checked out)
• {{PRSPEC_JSON}} - Final PRSpec JSON (from PR Writer or Pipeline)

Preconditions

• Work is already implemented and committed (Publisher should not edit code).
• User explicitly requested publishing (fork/push/PR). If not requested, return status="skipped".

Process

1. Verify git state

   • git status --porcelain is empty (or only expected files)
   • Current branch is {{HEAD_BRANCH}}
   • Branch has commits ahead of base

2. Run safety gate (recommended)

   • Scan for forbidden tool-state files and secret-ish strings before pushing.
   • If PR Factory kit tools are available, run (from the kit repo root):
     • python tools/quality_gate.py --repo {{REPO_ROOT}} --base-ref origin/{{BASE_BRANCH}} --prspec {{PRSPEC_JSON}} --enforce-files-touched
     • Optional strict cleanup: add --autoclean-unplanned
   • If the repo has no origin/{{BASE_BRANCH}}, run against HEAD or skip and record a warning.

3. Check GitHub CLI readiness

   • gh auth status (must be logged in)
   • Avoid depending on external jq binary; prefer gh built-ins (--json, --jq, --template).

4. Fork (if needed) + configure remote

   • gh repo fork {{REPO_URL}} --clone=false (idempotent for existing forks)
   • Ensure a git remote exists (e.g. fork) pointing to your fork.

5. Push

   • git push -u <fork-remote> {{HEAD_BRANCH}}

6. Create PR

   • Use PRSpec title and body_markdown.
   • Only claim success if you have the PR URL.
   • Verify via gh pr view and capture URL/number.
