Create PR

The request authorizes the repository's declared gates, relevant commits, PR metadata updates, one ordinary draft pull request or the confirmed native stack layers owned by the change, and their transitions to ready for review. It does not authorize implementation fixes or unrelated changes.

When the branch belongs to a native GitHub stack, read ../git-workflow/references/github-stacks.md. The request then authorizes submission and metadata reconciliation for the confirmed stack layers owned by the current change, not unrelated branches.

1. Inspect the working tree, staged diff, recent commits, remote default branch, stack topology when applicable, and any existing remote head. Preserve unrelated local work.
2. Stop if there are no relevant changes or commits ahead of the remote base. Continue without an empty commit when the work is already committed.
3. If currently on the base branch, create a focused branch named from the issue or change.
4. Establish the PR claim and publication requirements before publishing anything. Read the explicit request, linked issue or confirmed mini-spec, applicable project instructions, product docs, ADRs or durable decisions, the nearest DEFINITION_OF_READY.md, and the completion evidence supplied by the implementation workflow. If no source states the claim, reconstruct the narrowest claim supported by the commits and diff and label it as inferred.
5. Verify that code review, observed behavior, and the repository's project gate all passed on the exact current change. An explicitly accepted limitation must name the unverified behavior. Reuse a current project-gate result rather than running it again. If the gate result is missing or stale, run the declared gate once without weakening it.
6. Stop when required review or behavior evidence is missing, stale, failed, or unverified without explicit acceptance. Stop when the project gate fails. Report the exact missing evidence or failure and return the change to its implementation workflow. Do not test delivered behavior, inspect source as a substitute, or fix implementation, test, documentation, generated-artifact, compatibility, or CI gaps in this workflow. The only publication exception is an explicit user request for a draft PR to obtain a preview environment that does not otherwise exist. That PR must remain draft until behavior is tested on a preview tied to its exact revision.
7. Stage only relevant files, excluding secrets and unrelated local work. Commit uncommitted work with a concise Conventional Commit subject. Never amend and never skip hooks. Preserve already-published history and add a new commit for any correction.
8. Title each pull request with a Conventional Commit subject covering the whole change, since the squash merge makes that title the commit subject on the base branch. Fill the matching PR template for each submitted layer and preserve its structure. If none exists, use Summary, Testing, and Linked issues. Keep the body proportional to the change. Before writing it, search open and closed issues and recent sibling sessions or adjacent branches when available for related findings and duplicates. Put each closing keyword on its own line as Closes #N, and only on the layer that completes that issue. Upload local screenshots and videos with the GitHub CLI's --attach flag (gh pr create --attach '<file>#<alt text>', or gh pr edit and gh pr comment with the same flag) so the body links the uploaded asset; never commit evidence media to the repository. Put non-media evidence such as probe output or a plan inside a collapsed <details> block in the body or a comment.
9. Only after the publication checks pass, push an ordinary branch normally and set its upstream when needed, then open one draft PR against the remote default. For a verified native stack, use gh stack submit only after every submitted layer has current completion evidence; only guarded official stack operations may rebase or push with force-with-lease. Preserve bottom-to-top topology and keep each layer draft.
10. Run the PR-specific phase. Compare the actual PR diff, body, links, metadata, committed tests and documentation, supplied completion evidence, and facts that exist only after publication. Correct metadata-only gaps without a commit.
11. If the PR-specific phase or CI exposes a repository, code, behavior, test, documentation, generated-artifact, or compatibility gap, keep the PR draft and return the exact failure to the implementation workflow. Do not fix it here. A later caller may update the PR after the appropriate implementation, review, behavior-testing, and project-gate loop passes.
12. Invoke delivery-wait's foreground wait checks-terminal operation with the repository, pull request number, exact head, one --check per required check context, absolute deadline, an optional --state path, and --json; the harness passively awaits it without model heartbeats. When it returns, inspect unsuccessful logs. Report a validated code or behavior failure under step 11 rather than fixing it. If the host cannot passively await a subprocess, report the unsupported capability instead of polling through model turns.
13. Keep the PR in draft while any requirement for marking it ready or CI check is pending or failing. A PR opened to obtain a preview returns to the implementation workflow for black-box testing and cannot become ready in this run. If an expected pull-request workflow produces no run, read the PR's mergeable_state first: a dirty PR gets no pull-request runs, and no retrigger can help until the conflict is resolved. Continue monitoring pending checks; if they cannot reach a terminal result during the run, report their current state. Stop and report the exact blocker for a material decision, unrelated failure, unavailable external service, or validation that cannot be performed safely.
14. Once the PR is missing nothing required by the publication and PR-specific phases and all applicable CI is observed green for its exact head, mark it ready for review. Return every affected URL, native stack order when applicable, final states, metadata changes, supplied completion evidence, and observed readiness and CI evidence.
