/pr

description: Creates or updates a pull request (GitHub) or merge request (GitLab) for the current branch in the Conventional PR format — intent, summary, changes, rationale, and test plan. Pushes the branch if needed (asks before any force-push) and captures the implementation conversation's intent into the PR description. Use when a feature branch is ready for review or to refresh an existing PR/MR description.

Pull Request / Merge Request

This skill never commits working-tree changes — it only pushes existing commits and manages the PR/MR.

Step 1: Pre-flight

If `git rev-parse --is-inside-work-tree` does not return `true`, read `$CLAUDE_PLUGIN_ROOT/skills/init/references/multi-repo-detection.md` and apply it. When it returns `true`, resolve the repository root with `git rev-parse --show-toplevel`, including in a linked worktree or subdirectory. In a detected workspace:

• Filter to child repos on a non-default branch with commits ahead of the default branch (detect the default branch per `$CLAUDE_PLUGIN_ROOT/skills/pr/references/default-branch-detection.md`, run inside each repo). Warn and skip any repo whose default branch cannot be detected.
• 0 candidates → "No repositories in this workspace have branches with changes ready for a PR." Stop. 1 → announce which repo was detected and run Steps 2–7 inside it. Multiple → ask (AskUserQuestion): **All** or one specific repo.
• **All** → run Steps 2–7 per repo sequentially (show a `## <repo-name>` heading before Step 2; run all commands inside that repo). Any per-repo stop condition (unknown platform, CLI cancel, update-flow Cancel, …) stops only that repo — record the outcome for the Step 8 summary and continue with the next. Only the gates below halt the whole run.

**Verify git state** (stop gates):

1. Not inside a git repository → inform the user and stop. 2. Default-branch detection (reference above) fails → "Could not detect the default branch. Ensure `origin` is configured and has been fetched." Stop. 3. On the default branch → "You're on the default branch (`<branch>`). Switch to a feature branch first." Stop.

Step 2: Platform Detection

Read `$CLAUDE_PLUGIN_ROOT/skills/pr/references/platform-detection.md` and apply the **Platform Detection Algorithm**. Unknown platform → inform the user and stop.

Step 3: CLI Availability

Apply the reference's **CLI Verification** section. If the CLI is missing, offer to install it per its **CLI Installation** section (ask: **Install** / **Cancel**). On Cancel or install failure → provide manual installation instructions and stop. Installed but unauthenticated → "Run `gh/glab auth login` to authenticate, then re-run `/optimus:pr`." Stop.

Step 4: Push and Existing PR/MR Check

If the branch is not on the remote (`git ls-remote --heads origin <branch>`): with no commits on the branch → "No commits on this branch yet. Commit your changes first." Stop. Otherwise `git push -u origin <branch>`.

If the branch is on the remote with unpushed commits, check divergence first: `git rev-list --count HEAD..origin/<branch>`

• Count `0` → fast-forward push: `git push origin <branch>`
• Count `> 0` → the remote has commits not in local history (typical after a rebase). NEVER plain-push. Ask (AskUserQuestion "Diverged branch"): **Force push** → run `git push --force-with-lease origin <branch>`; if the lease is rejected → "Force push rejected — the remote gained new commits since your last fetch. Review them before overwriting." Stop. **Cancel** → tell the user to reconcile and push manually, then re-run `/optimus:pr`. Stop.

Check for an existing PR/MR:

• **GitHub:** `gh pr view --json number,state,title,body,url,baseRefName 2>/dev/null`
• **GitLab:** `glab mr view --output json 2>/dev/null`

Open PR/MR → save its `baseRefName` / `target_branch` as the **target branch** and go to Step 6 (Update Flow). Closed/merged or none → Step 5 (Create Flow).

Step 5: Create Flow

Default branch: on GitHub, `gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name'` is authoritative over Step 1's local detection (local `origin/HEAD` may be stale); on GitLab, use Step 1's detection.

Gather the branch's commits and diff vs `origin/<default-branch>`. No commits ahead → "This branch has no changes compared to `<default-branch>`." Stop.

Detect intent context

Classify into one of three states before generating content:

1. **Conversation context** — this conversation implemented the branch: Edit/Write/NotebookEdit calls touched files in the diff, or the conversation discussed the problem, design decisions, or non-goals. A `## TDD Summary` block with `### Behaviors Implemented` (literal, case-sensitive — emitted by `/optimus:tdd`) is a strong state-1 signal; apply the population rule below. 2. **Existing PR body has `## Intent`** (Update Flow only — see the detection rule in the template). 3. **None** — when uncertain, prefer this state over fabricating. Ask (AskUserQuestion "Intent capture"): **Add intent now** → have the user reply with Problem / Scope / Non-goals / Key decisions on separate lines in a plain message (blank lines skip a sub-field); **Skip** → omit the section entirely, no stub.

Suppress the state-3 prompt in states 1 and 2.

Generate content

Read `$CLAUDE_PLUGIN_ROOT/skills/pr/references/pr-template.md` and generate a title and body. Populate `## Intent` from the conversation (state 1) or the user's reply (state 3), including only sub-fields the source actually answers.

**TDD Summary population rule** — when a `## TDD Summary` block is present, fill the body from the summary block:

• **Intent → Scope**: one bullet per `### Behaviors Implemented` row with Status `✓ Complete`, description verbatim.
• **Intent → Non-goals**: one bullet per `Not started` row, and per `Skipped` row with its reason and skipped test name; omit if none.
• **Intent → Key decisions**: refactor-step reasoning captured in the conversation; omit rather than i
