open-prlisted

Open a pull request the only sanctioned way: as three atomic acts that are impossible to forget because this skill performs all of them in one invocation. The failure class it closes: a PR opened, then the reviewer review task never created and the reviewer plus coordinator never notified — so a delivery sits ready-but-invisible until someone polls. This skill COMPOSES two canonical skills — it does not reinvent them: - **dispatch-task-create** (VantageRegistry canonical) — for act 2, so the review task ships the VERIFICATION + TESTS + IRP blocks that `enforce-task-quality` and `enforce-pi-task-doctrine` require. - **dispatch-message** v2 (VantageRegistry canonical) — for act 3, so the message lands past every fleet hook on the first try with the telegraphic grid. ## THE MARKER CONTRACT Every `gh pr create` opened through this skill MUST carry the fixed marker string, appended to the command line as a shell comment: ``` # via-open-pr ``` This marker is a contract, not decoration. The companion PreToolUse hook `enforce-pr-opened-via-skill` REQUIRES this exact marker on any `gh pr create`: a raw `gh pr create` without `# via-open-pr` is blocked, forcing every PR through this skill so acts 2 and 3 can never be skipped. The marker string is literal and fixed — never paraphrased, never abbreviated. Downstream enforcement matches it byte for byte. ## INPUTS (required) - `repo`: owner/name (e.g. `elpiarthera/ElPi-Corp`). - `head_branch`: the branch to open the PR from
