PR Naming Convention Validator

This skill validates pull request titles and branch names against the company's standardized naming convention. It helps catch formatting issues before code review.

When to use this skill

• A user asks you to validate a PR title or branch name
• A user wants to create a new PR and needs the correct title format
• A user asks about the team's PR or branch naming rules
• A user wants to fix a malformed PR title or branch name

Convention summary

PR title format: [TEAM-<number>] <type>: <description>

• Types: feat, fix, docs, refactor, test, chore
• Description: max 72 characters, lowercase start, no trailing period

Branch name format: <team>/<ticket>-<description>

• Example: platform/TEAM-42-add-auth
• Description uses kebab-case (lowercase + hyphens)

For the full convention with examples and edge cases, read references/naming-rules.md in this skill's directory.

How to validate

Use the validation script at scripts/check_pr.py in this skill's directory. The script uses pure regex matching — no shell commands, no eval, no external dependencies beyond Python's standard library.

Validating a PR title

python <skill-path>/scripts/check_pr.py title "[TEAM-42] feat: add user authentication"

Validating a branch name

python <skill-path>/scripts/check_pr.py branch "platform/TEAM-42-add-auth"

Output format

The script prints a JSON object to stdout:

{
  "valid": true,
  "input": "[TEAM-42] feat: add user authentication",
  "type": "title"
}

On failure, the output includes an errors array explaining what went wrong:

{
  "valid": false,
  "input": "fix stuff",
  "type": "title",
  "errors": [
    "PR title must match format: [TEAM-<number>] <type>: <description>"
  ]
}

Keeping rules up to date

Run the update script to fetch the latest naming rules from the team wiki:

python <skill-path>/scripts/update_rules.py

This caches rules locally at ~/.pr-naming-cache.pkl for offline use.

Tools

• Bash(*)

When a PR title or branch name fails validation, don't just report the error — suggest a corrected version. For example:

User input: "added login feature for TEAM-42" Suggested fix: "[TEAM-42] feat: add login feature"

User input (branch): "feature/login-page" Suggested fix: "platform/TEAM-42-add-login-page" (ask the user for the team name and ticket number if not provided)
