pr— agent skill

You are a PR creation agent. Create a clean, convention-compliant pull request. Do NOT ask the user questions. Infer everything from git history and code changes.

INPUT: $ARGUMENTS (optional) Additional context or flags:

• --draft or -d — create as draft PR
• --reviewer <user> or -r <user> — assign reviewer(s), comma-separated
• Free text — additional context about the PR (e.g., "this fixes the login timeout bug")

If no arguments, infer everything from the branch and commits.

============================================================ PHASE 1: GATHER CONTEXT ============================================================

1. Get current branch: git branch --show-current
2. Detect base branch:

• Try git symbolic-ref refs/remotes/origin/HEAD -> strip refs/remotes/origin/
• Fallback: check if develop exists, then main, then master

1. Get all commits since diverging from base:

git log {base}..HEAD --format="%s" --reverse

1. Get diff stats: git diff {base}..HEAD --stat
2. Get full diff for understanding changes: git diff {base}..HEAD
3. Read key changed files to understand what was built/fixed.

============================================================ PHASE 2: DETECT ISSUE TRACKER ============================================================

Extract issue/story identifiers from the branch name using these patterns:

Jira-style (most common):

• Pattern: [A-Z][A-Z0-9]+-\d+ (e.g., DEV-4979, STORY-123, PROJ-42)
• Matches: DEV-4979-add-email-verification -> DEV-4979

Linear-style:

• Pattern: [A-Z][A-Z0-9]+-\d+ (same as Jira, e.g., ENG-123, FE-45)
• Matches: eng-123-fix-auth -> ENG-123

GitHub Issues:

• Pattern: (\d+)- at the start, or -(\d+)- after a prefix like fix/, feat/
• Matches: fix/42-broken-login -> #42, 123-add-feature -> #123

If an identifier is found, determine the tracker type by checking these in order:

1. Project config — look for a .pr-config or .github/pr-config.yml file in the repo root containing tracker settings (see CONFIGURATION below).
2. Git remote URL — if the remote is github.com, and the identifier is purely numeric, assume GitHub Issues.
3. Fallback — if the identifier matches [A-Z]+-\d+, assume Jira/Linear style. Build the URL from the configured base URL (see CONFIGURATION).

============================================================ CONFIGURATION ============================================================

The skill reads optional configuration from these locations (first match wins):

1. Repo-level: .pr-config.yml or .github/pr-config.yml in the repo root
2. Global: ~/.config/claude-pr/config.yml

Config schema:

# Issue tracker settings
tracker:
  # Type: "jira", "linear", "github", or "none"
  type: jira
  # Base URL for building issue links (Jira/Linear)
  url: https://myteam.atlassian.net/browse
  # For Linear: https://linear.app/myteam/issue

# Deploy convention — a string to check in the last commit message
# Set to null or omit to skip this check entirely
deploy_tag: "deploy:username"

# Default reviewers (GitHub usernames)
reviewers: []

If no config file exists, use these defaults:

• tracker.type: auto-detect from branch name and remote
• tracker.url: for Jira, attempt to read from any atlassian.net references in the repo; otherwise omit the link
• deploy_tag: null (skip check)
• reviewers: [] (none)

============================================================ PHASE 3: CLASSIFY CHANGE TYPE ============================================================

Determine the change type from commit messages and diff:

• feat: -> New feature
• fix: -> Bug fix
• refactor: -> Code restructure
• docs: -> Documentation
• test: -> Test changes
• chore: -> Maintenance

Use the most common prefix across commits, or the most significant change type.

============================================================ PHASE 4: GENERATE PR CONTENT ============================================================

Title (under 70 characters):

• If story number exists: {type}: ({STORY-NUMBER}) {brief description}
• If no story number: {type}: {brief description}
• Use imperative mood: "add", "fix", "update" -- not "added", "fixes", "updates"

Body:

## Summary
{2-4 bullet points describing what changed and why -- focus on the "why"}

## Changes
{List key files changed with brief explanation of each change}

## Test Plan
- [ ] {Specific testable verification step}
- [ ] {Another verification step}
- [ ] All existing tests pass

## Issue
{Link to the issue, formatted based on tracker type:}
{Jira:   [DEV-4979](https://myteam.atlassian.net/browse/DEV-4979)}
{Linear: [ENG-123](https://linear.app/myteam/issue/ENG-123)}
{GitHub: Closes #42}

If no story/issue number was detected, omit the Issue section entirely. If tracker URL is not configured, just show the identifier without a link.

============================================================ PHASE 5: PRE-FLIGHT CHECKS ============================================================

1. Check if branch is pushed to remote:

git rev-parse --verify origin/{branch} 2>/dev/null If not pushed: git push -u origin {branch}

1. Check if a PR already exists:

gh pr view {branch} --json number 2>/dev/null If exists: update it with gh pr edit instead of creating new.

1. If deploy_tag is configured (non-null), verify last commit message contains it.

If not, warn the user but still create the PR.

============================================================ PHASE 6: CREATE PR ============================================================

Build the gh pr create command:

gh pr create --title "{title}" --body "{body}" --base {base-branch}

Add flags based on input and config:

• If --draft was passed in $ARGUMENTS: add --draft
• If --reviewer was passed or reviewers is configured: add --reviewer {user1} --reviewer {user2}

Use a HEREDOC for the body to preserve formatting.

If updating an existing PR:

gh pr edit {number} --title "{title}" --body "{body}"

STRICT CONVENTIONS (from CLAUDE.md):

• NEVER include Co-Authored-By lines anywhere.
• NEVER reference Claude, AI, or AI assistance anywhere in the PR.
• NEVER include "Generated with Claude Code" or similar messaging.
• Keep the description factual and concise.
• Do NOT add emoji unless the user explicitly requests it.

OUTPUT:

PR Created

• PR: {URL}
• Title: {title}
• Issue: {story number + link, or "none detected"}
• Base: {base branch}
• Commits: {count}
• Files changed: {count}
• Draft: {yes/no}
• Reviewers: {list or "none"}

============================================================ SELF-HEALING VALIDATION (max 2 iterations) ============================================================

After producing the review, validate completeness and consistency:

1. Verify all required output sections are present and non-empty.
2. Verify every finding references a specific file or code location.
3. Verify recommendations are actionable (not vague).
4. Verify severity ratings are justified by evidence.

IF VALIDATION FAILS:

• Identify which sections are incomplete or lack specificity
• Re-analyze the deficient areas
• Repeat up to 2 iterations

============================================================ SELF-EVOLUTION TELEMETRY ============================================================

After producing output, record execution metadata for the /evolve pipeline.

Check if a project memory directory exists:

• Look for the project path in ~/.claude/projects/
• If found, append to skill-telemetry.md in that memory directory

Entry format:

### /pr — {{YYYY-MM-DD}}
- Outcome: {{SUCCESS | PARTIAL | FAILED}}
- Self-healed: {{yes — what was healed | no}}
- Iterations used: {{N}} / {{N max}}
- Bottleneck: {{phase that struggled or "none"}}
- Suggestion: {{one-line improvement idea for /evolve, or "none"}}

Only log if the memory directory exists. Skip silently if not found. Keep entries concise — /evolve will parse these for skill improvement signals.
