# GitHub Pull Request Workflow

You manage the GitHub PR lifecycle: create PRs with auto-composed descriptions,

inspect PR status, and merge with review verification. You start with an empty

context -- gather everything you need below.

Arguments: `$ARGUMENTS`

## Prompt Design Principles

- **Opt-in, not automatic.** PRs are a deliberate choice. Never create a PR unless

explicitly asked. Direct-to-main is the default workflow for solo development.

- **Zero-overhead descriptions.** PR bodies are composed from existing review metadata

(CODEREVIEW.md, SECURITY.md, TESTING.md, SPEC.md) and commit messages. No extra work from the user.

- **Idempotent operations.** Creating a PR when one already exists for the branch shows

the existing PR. Merging a PR that is already merged reports the fact. Never duplicate.

- **Evidence grounding.** Review verdicts included in PR descriptions come from actual

review file metadata, not from re-running reviews or guessing.

---

## Step 1: Parse Arguments and Determine Mode

Parse `$ARGUMENTS` to determine the operation:

| Input | Mode | Action |

|-------|------|--------|

| *(empty)* | **create** | Create a PR for the current branch |

| `<branch-name>` | **create** | Create a feature branch with that name, then create a PR |

| `status` | **status** | Show status of the current branch's PR |

| `<number>` or `<url>` | **inspect** | Show details of a specific PR |

| `merge` | **merge** | Merge the current branch's PR |

| `list` | **list** | List open PRs for this repo |

## Step 2: Verify Prerequisites

```bash

# Verify gh is authenticated

gh auth status

# Get repo and branch context

git remote get-url origin

git rev-parse --abbrev-ref HEAD

git rev-parse --show-toplevel

```

If `gh auth status` fails, report the error and stop.

If the repo has no GitHub remote, report that and stop.

## Step 3: Execute Mode

### Mode: create

**3a. Handle branch.**

```bash

CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)

```

If on `main` and a branch name was provided in `$ARGUMENTS`:

```bash

git checkout -b "$BRANCH_NAME"

```

If on `main` and no branch name was provided, derive one from the most recent commit

message (e.g., `feat/add-pr-skill`). Use lowercase, hyphens, no special characters.

Prefix with `feat/`, `fix/`, or `docs/` based on the commit content.

If already on a non-main branch, use it as-is.

**3b. Check for existing PR.**

```bash

gh pr list --head "$(git rev-parse --abbrev-ref HEAD)" --json number,url,state --jq '.[]'

```

If a PR already exists for this branch, display it and stop. Do not create a duplicate.

**3c. Gather context for PR description.**

Collect commit history since diverging from main:

```bash

git log --oneline main..HEAD

git diff --stat main...HEAD

```

Read review metadata from persistent files (if they exist). Extract only the

metadata footer line from each file:

```bash

grep 'REVIEW_META' CODEREVIEW.md 2>/dev/null

grep 'SECURITY_META' SECURITY.md 2>/dev/null

grep 'TESTING_META' TESTING.md 2>/dev/null

grep 'SPEC_META' SPEC.md 2>/dev/null

```

**3d. Compose PR title and body.**

- **Title:** Derive from the commit history. If there is one commit, use its message.

If there are multiple, write a concise summary (under 70 characters).

- **Body:** Use this structure:

```markdown

## Summary

[2-5 bullet points summarizing the changes, derived from commit messages and diff stats]

## Spec

[If SPEC.md exists: spec title, criteria_met/criteria_total. If not: "No spec."]

## Review Status

| Review | Verdict | Date |

|--------|---------|------|

| Code Review | [PASS/BLOCKED/not run] | [date or n/a] |

| Security | [PASS/BLOCKED/not run] | [date or n/a] |

| Test Strategy | [assessed/not run] | [date or n/a] |

[If any BLOCK items exist, list them here]

## Commits

[git log --oneline main..HEAD output]

```

Populate the Review Status table from the REVIEW_META JSON. If a review file does

not exist or has no metadata, mark as "not run." PASS means zero BLOCK items.

BLOCKED means one or more BLOCK items remain.

**3e. Push and create the PR.**

```bash

# Push branch to remote (set upstream if needed)

git push -u origin "$(git rev-parse --abbrev-ref HEAD)"

# Create the PR

gh pr create --title "<title>" --body "<body>"

```

Report the PR URL.

### Mode: status

```bash

gh pr view --json number,title,state,reviews,statusCheckRollup,mergeable,url

```

Display: PR number, title, state, review status, CI check results, merge readiness.

If there are review comments, summarize them:

```bash

gh pr view --json comments --jq '.comments[].body'

```

### Mode: inspect

```bash

gh pr view <number_or_url> --json number,title,state,body,reviews,statusCheckRollup,comments,url

```

Display the PR details and summarize any review comments.

### Mode: merge

**Verify review gate.** Check that the codereview marker is valid for the current diff,

using the same logic as the pre-push hook:

```bash

PROJ_HASH=$(git rev-parse --show-toplevel | md5sum | cut -c1-8)

MARKER_FILE="/tmp/.claude-codereview-${PROJ_HASH}"

UPSTREAM=$(git rev-parse --abbrev-ref '@{upstream}' 2>/dev/null) || UPSTREAM="origin/$(git rev-parse --abbrev-ref HEAD)"

if git rev-parse "${UPSTREAM}" >/dev/null 2>&1; then

DIFF_HASH=$(git diff "${UPSTREAM}" -- ':!CODEREVIEW.md' ':!SECURITY.md' ':!TESTING.md' ':!SPEC.md' | sha256sum | cut -c1-16)

else

EMPTY_TREE=$(git hash-object -t tree /dev/null)

DIFF_HASH=$(git diff "${EMPTY_TREE}" -- ':!CODEREVIEW.md' ':!SECURITY.md' ':!TESTING.md' ':!SPEC.md' | sha256sum | cut -c1-16)

fi

```

If the marker file does not exist or its content does not match the current diff hash,

report that `/codereview` must be run first and stop. Do not merge without a passing review.

If the marker is valid:

```bash

gh pr merge --squash --delete-branch

git checkout main

git pull

```

Report that the PR was merged and the branch was cleaned up.

### Mode: list

```bash

gh pr list --json number,title,headRefName,state,updatedAt --template '{{range .}}#{{.number}} {{.title}} ({{.headRefName}}) {{.state}} {{timeago .updatedAt}}{{"\n"}}{{end}}'

```

Display the list. If no open PRs exist, say so.

## Step 4: Output

End with a one-line summary of what happened:

- **create:** "PR #N created: <url>"

- **status:** "PR #N: <state>, <merge readiness>"

- **inspect:** "PR #N: <title> (<state>)"

- **merge:** "PR #N merged to main. Branch <name> deleted."

- **list:** "N open PR(s)." or "No open PRs."
