PR

Commit, push, and create a pull request in one automated step. Never prompt the user for input — make opinionated decisions at every step.

Workflow

1. Gather Context

First, detect the repository's base branch:

gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name'

If gh is not available or the command fails, fall back to:

git remote show origin | grep 'HEAD branch' | sed 's/.*: //'

Use the detected value as ``.

Detect the PR base branch

The current branch may have been created from a non-default branch (e.g., for stacked PRs). Check the reflog for the branch creation point:

git reflog show $(git branch --show-current) --format='%gs' | tail -1

This produces output like branch: Created from develop, branch: Created from origin/develop, or branch: Created from refs/heads/feature/parent. If the last entry matches branch: Created from , extract ` and normalize it by stripping any refs/heads/, refs/remotes/origin/, or leading origin/` prefix.

If a source branch name was extracted, verify it is a valid base for the PR. Run these checks in order, stopping at the first failure:

1. Not the current branch: The source branch must differ from the current branch.
2. Exists on the remote: Note that git ls-remote always exits 0 regardless of whether the branch exists, so check for non-empty output:

``bash git ls-remote --heads origin | grep -q . ``

1. Not already merged into the default branch: The source branch may have been merged into the default branch since this branch was created (e.g., a parent feature branch that has since landed). Check whether the source branch is an ancestor of the default branch:

``bash git fetch origin --quiet git merge-base --is-ancestor origin/ origin/ ``

If the exit code is 0, the source branch has been fully merged into the default branch. Skip it and use ` as ` instead.

If all three checks pass, use the source branch as `. If any check fails, use as `.

Then run these commands in parallel to understand the current state:

# Current branch and changed files
git status

# Staged changes
git diff --cached

# Unstaged changes
git diff

# Recent commit messages for style reference
git log --oneline -10

# Full diff of this branch against the base branch
git diff  ...HEAD

# Commit history of this branch since diverging from the base branch
git log --oneline  ..HEAD

# Check remote tracking status
git rev-parse --abbrev-ref --symbolic-full-name @{u} 2> /dev/null || echo "no upstream"

2. Detect Connected Issues

Search for GitHub issues that this branch addresses. Combine results from the strategies below, deduplicate by issue number, and record the final list for use in the commit message (step 4) and PR body (step 7).

Strategy 1 — Issue numbers in the branch name

Extract the current branch name. Look for issue numbers in patterns like:

• TYPE/N-description (e.g., fix/42-login-bug → #42)
• TYPE/description-N (e.g., feature/login-bug-42 → #42)
• TYPE/issue-N or TYPE/issue-N-description (e.g., fix/issue-42 → #42)
• N-description (e.g., 42-add-login → #42)

For each candidate number, verify it refers to an existing issue:

gh issue view NUMBER --json number,title,state --jq '.number' 2> /dev/null

Only include it if the command succeeds (the issue exists).

Strategy 2 — Issue references in commit messages

Scan the git log ..HEAD output (already gathered in step 1) for #N references. Collect all unique issue numbers. For each, verify it refers to an actual issue:

gh issue view NUMBER --json number,title,state --jq '.number' 2> /dev/null

Strategy 3 — GitHub issue search by branch slug

Only run this strategy if strategies 1 and 2 found zero issues.

Extract the slug portion of the branch name (everything after the first /). Convert hyphens to spaces to form search keywords. Search for matching open issues:

gh issue list --search "KEYWORDS" --state open --json number,title --limit 5

Evaluate the results:

• If exactly one issue is returned, include it.
• If multiple issues are returned, compare each issue title against the branch slug. Include an issue only if its title, when slugified (lowercased, spaces and special characters replaced with hyphens), is a near-exact match with the branch slug. If no single issue clearly matches, include none.
• If zero issues are returned, skip.

Combine results

Merge issue numbers from all three strategies into a single deduplicated list. Preserve the order: branch-name issues first, then commit-message issues, then search-matched issues. Note the branch type prefix (fix/* vs other) for choosing the closing keyword later.

3. Validate Preconditions

Stop and report an error if any of these are true:

• The current branch is the base branch. Do not create a PR from the base branch to itself.
• There are no changes to commit and no commits ahead of the base branch. There is nothing to open a PR for.

4. Commit Changes (if needed)

If there are no staged changes, unstaged changes, or untracked files, skip this step.

Never stage files that likely contain secrets (.env, credentials.json, *.pem, *.key, etc.). If such files are detected, warn the user and exclude them.

Handle plan files

Before identifying logical chunks, check for plan files among the uncommitted changes. Plan files live under docs/plans/ and its subdirectories (todo/, done/). If any Markdown files in these directories are among the staged, unstaged, or untracked files, apply [Plan-Aware Commits](#plan-aware-commits) rules to them.

Plan files always form their own logical chunk, committed separately from code changes. Process the plan file chunk first, then proceed with the remaining changes.

Identify logical chunks

Review all uncommitted changes (excluding any plan files already handled above) and group them into the smallest logical chunks. Each chunk should be a self-contained, coherent change that makes sense on its own:

1. Examine the diff: Look at all changed and untracked files and understand what each change accomplishes.
2. Group by purpose: Changes that serve the same purpose belong together. A new function and its tests are one chunk, but an unrelated formatting fix is a separate chunk.
3. Check for independence: If a change can be committed on its own without leaving the codebase in a broken or inconsistent state, it is a candidate for its own chunk.
4. Respect dependencies: If change B depends on change A, commit A first.

If all changes form a single logical chunk, create one commit. If they form multiple chunks, create a commit for each, processing them sequentially.

Create each commit

For each chunk:

1. Stage only the files belonging to the current chunk using git add with specific file paths.
2. Analyze the diff to generate a commit message:

• Examine git log --oneline -10 output to match the repository's commit message style.
• Determine the commit type (feat, fix, docs, refactor, test, chore, style) based on the changes.
• Write a concise description (under 72 characters) focused on why the change was made.
• Reference connected issues detected in step 2. For fix/* branches, use fixes #N; for other branch types, use closes #N. If no connected issues were detected, omit issue references from the commit message. Only reference issues in the commit that most directly addresses them.

1. Create the commit using GPG signing and a HEREDOC:

git commit -S -m "$(
  cat ..HEAD` and `git diff ...HEAD`) to generate the PR title and body.

#### Title

- Under 70 characters.
- Summarize the overall change, not individual commits.
- Use sentence case (capitalize the first word only).
- Do not include a conventional-commit type prefix in the PR title.

#### Body

Use the following format:

```markdown
## Summary

- Bullet point describing key change 1
- Bullet point describing key change 2
- Bullet point describing key change 3

## Test plan

- [ ] TODO: describe how to verify this change

## Closes

Closes #N

Keep the summary to 1-4 bullet points. Focus on what changed and why.

If connected issues were detected in step 2, add a ## Closes section after ## Test plan. Use one line per issue with the appropriate keyword:

• For issues detected from a fix/* branch: Fixes #N
• For all other issues: Closes #N

If no connected issues were detected, omit the ## Closes section entirely.

Create the PR

First, generate a unique temporary file path using mktemp:

mktemp /tmp/pr-body-XXXXXX
# Returns a unique path, e.g.: /tmp/pr-body-x4y5z6

Then use the Write tool to write the full PR body (Summary, Test plan, and Closes sections) to the exact path returned by mktemp. In the examples below, TMPFILE is a placeholder for that path.

Then create the PR with --body-file:

gh pr create --title "the pr title" --body-file TMPFILE

Pass --base if ` differs from . Do not pass --draft`. Do not add labels or reviewers.

Always remove the tmpfile after the PR creation attempt, regardless of whether it succeeded or failed. Issue the cleanup as a separate Bash tool call, not chained onto gh pr create:

rm -f TMPFILE

Each Bash tool call runs unconditionally and the prior call's exit code is preserved by the harness, so a separate call cleans up after both successful and failed PR creations without any shell-level wrapping. Never combine the two with ; followed by an exit-code preservation idiom such as gh pr create ...; status=$?; rm -f TMPFILE; exit $status. In zsh (the macOS default shell), status is a read-only built-in alias for $?, so the assignment fails with read-only variable: status and falsely reports a successful PR creation as failed. See plugins/use-git/skills/use-git/references/tmpfile-pattern.md for the full rationale.

8. Report Results

After the PR is created, report:

1. The PR URL (returned by gh pr create).
2. The PR title.
3. The commit hash(es) included.
4. A brief summary of what was committed and pushed.
5. Connected issues (if any) and the closing keywords used.

Plan-Aware Commits

When plan files are detected among uncommitted changes, apply the rules in this section during step 4.

Detecting Plan Files

Plan files live under docs/plans/ and its subdirectories (todo/, done/). Look for Markdown files in these directories among the changed or untracked files.

Plan Name Cleanup

Well-named plans follow the pattern YYYY-MM-DD-meaningful-description.md. Auto-generated names use nonsensical word combinations (e.g., ethereal-booping-sunbeam.md, quizzical-imagining-cerf.md).

Every time a plan file is part of a commit, check its filename. If the name lacks a datestamp prefix or uses a nonsensical auto-generated name:

1. Read the plan file to understand its content.
2. Choose a meaningful slug derived from the plan's title or purpose (e.g., consolidate-ci-workflows, add-user-authentication).
3. Rename the file to YYYY-MM-DD-.md, using the current date for new plans or the date from the plan's title/content if one is stated.
4. Stage both the deletion of the old path and the addition of the new path.

If the filename already has a datestamp prefix and a meaningful description, leave it as-is.

Moving Completed Plans

Creating a PR typically means the work described in a plan is complete. When plan files are detected among the changes:

1. Check whether the plan's work is complete. Indicators: all the code changes on the branch correspond to the plan, or the user has already stated that the work is done.
2. If the work is complete, apply [Plan Name Cleanup](#plan-name-cleanup) first (if needed), so any rename happens before the move.
3. Move the (possibly renamed) plan file to docs/plans/done/ (creating the directory if it does not exist). If both a rename and a move apply, perform a single git mv from the original path directly to the final destination (e.g., docs/plans/done/YYYY-MM-DD-slug.md).
4. If the plan is currently in docs/plans/todo/, the move goes from todo/ to done/.
5. If the plan is in the docs/plans/ root, the move goes from there to done/.
6. Stage the rename (if any) and the file move together as part of the plan commit.

Do not move a plan to done/ if the work is only partially complete. Plans for work still in progress should stay in docs/plans/todo/ or the docs/plans/ root.

Plan Commit Message

When committing plan files, use a message like docs: add plan for for new plans, or docs: move plan to done for when moving a completed plan.

Error Handling

• On the base branch: Report that PRs cannot be created from the base branch. Suggest creating a feature branch first.
• Nothing to commit and no commits ahead: Report there is nothing to create a PR for.
• Pre-commit hook failure: Fix the issue, re-stage, and create a new commit (never amend).
• Lint issues unresolved: If the lint-and-fix skill reports unresolved issues, skipped items, or a required linter that cannot run, stop before pushing. Report the remaining lint errors and suggest the user fix them manually before retrying /pr.
• Push rejected: Report the error. Suggest git pull --rebase if the remote has diverged. Never force push.
• PR already exists: If gh pr create fails because a PR already exists for this branch, run gh pr view --web to open the existing PR and report it to the user.
• No gh CLI: Report that the gh CLI is required and link to https://cli.github.com/.
• Secret files detected: Warn the user and exclude them from staging. Continue with the remaining files.
• Issue detection fails: If gh issue view or gh issue list commands fail (network error, auth issue), skip issue detection silently and proceed without the ## Closes section. Issue detection is best-effort and must never block PR creation.
• Detected issue is already closed: Still include it in the ## Closes section. GitHub handles this gracefully (the keyword is a no-op for already-closed issues, and it still creates a visible cross-reference).
