Ca Pr

$ca-pr — open a pull request

The only permitted path to a pull request. Every change lands through a PR — never a direct write or force-push to the default branch. No PR is drafted while any BLOCK-level review finding stands.

Flow

Routes to the finishing-a-development-branch skill, open-PR path. The orchestrator reads the current

branch, its diff against the base, and the commit log to determine what changed and which reviewers

apply, then:

• Confirm the commit gate cleared this session (commit-gate green, or $ca-commit completed).
• Path matrix — inspect the diff and dispatch the reviewer agents the change demands:
• auth / crypto / middleware paths → auth-crypto-reviewer + security-reviewer
• migration files → migration-reviewer
• dependency manifests → dependency-reviewer
• all paths → coverage-auditor
• Run reviewers in parallel where there are no dependencies.
• BLOCK check — any CRITICAL or HIGH finding STOPs the flow; present it and do not draft the PR.

The user resolves, re-runs $ca-commit, then $ca-pr.

• Stage the PR once all BLOCK findings clear: concise title; summary of what changed and why; a

bulleted test plan; a conflict-hierarchy tradeoff citation for any non-obvious tradeoff; a link to

any ADR the change implements or contradicts. The PR body is a user-facing deliverable: before

composing it, load ${CLAUDE_PLUGIN_ROOT}/includes/anti-slop-design/core.md and the

medium-documents leaf, and apply at least the §3.A em-dash ban and the §3.B copy self-audit to the

prose. Then gh pr create; return the URL.

• Auto-attach the babysitter — resolve the flag with the canonical resolver, never by eyeballing

the env var (so the accepted on|true|1 spellings and the dormancy gate can't drift):

   python3 "${CLAUDE_PLUGIN_ROOT}/hooks/babysit.py" --root "<project-root>" || python "${CLAUDE_PLUGIN_ROOT}/hooks/babysit.py" --root "<project-root>"

It prints one JSON line, e.g. {"enabled": true, "on_red": "propose"}. Only when enabled is

true (the global flag CODEARBITER_BABYSIT is on — default off, mirrors CODEARBITER_PRUNE — and

the repo is arbiter-active), attach a CI watcher to the PR just opened, equivalent to

$ca-watch <new-PR>. When enabled is false, do nothing here — the user can still run $ca-watch

ad-hoc. Never enable the flag on the user's behalf.

Routes to

finishing-a-development-branch (${CLAUDE_PLUGIN_ROOT}/routines/finishing-a-development-branch/SKILL.md),

open-PR path.

When NOT to use

• Staged changes not yet committed → $ca-commit.
• Review a diff without opening a PR → $ca-review.
• A pre-implementation security pass → $ca-threat-model.

Hard gate

MUST NOT open a PR while any BLOCK-level (CRITICAL or HIGH) finding is unresolved. MUST NOT skip a

reviewer the path matrix requires. MUST NOT open a PR before the commit gate ran this session. MUST

NOT open a PR, write, or force-push directly to the default branch. MUST NOT auto-attach a CI watcher

unless CODEARBITER_BABYSIT is on, and MUST NOT enable that flag on the user's behalf.
