Pull request

Create or update one GitHub pull request: safe gh operations, and a body a reviewer can act on.

This skill owns the push, the PR, its title, body, template conventions, and initial state. Land the commits with the commit skill first. When the branch is stacked (gh stack view --json succeeds, the resolved base is another feature branch, or the user asks for a stack), stacked-pr owns branch order, base resolution, submit, rebase, and merge sequence.

Modes

• Create: no exact PR exists for this target repository and head repository/branch. Open one in the user's preferred initial state, defaulting to draft.
• Update: one exact open PR exists for this target repository and head repository/branch. Audit its body against the diff, then show the URL and the proposed edits and ask before changing title, body, or metadata.
• Draft-only: the user wants copy, a state read, or metadata suggestions. Deliver them and stop, with no push, create, or edit.

A closed or merged PR is historical state, not Update mode. Report its URL and state, then ask whether the user wants a new PR when commits remain against the target base. Edit, reopen, or replace it only when the user explicitly chooses that operation.

Terminal states are created, updated, draft-only, and blocked. Reaching one ends the turn. Further edits, labels, reviewers, issue comments, or cleanup wait for a new instruction.

Claims

Everything the title, body, or reported metadata asserts is a claim, and every claim ships verified against evidence that can establish that class of claim. A source can prove one class and be only a discovery hint for another.
