PR Labeling

Coding Automation

Install PR Labeling

Pick your agent. Every command is ready to paste.

$npx skills add vercel-labs/skills --skill pr-labeling

The open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.

01

Install it

Run the command above, or upload the folder in Claude.

02

Ask naturally

Describe the task. Your agent loads pr-labeling when the request matches its description.

03

Name it if needed

If it does not trigger, say “use the pr-labeling skill”. In Codex, type $pr-labeling.

Label a skills CLI pull request

  1. Use read_pull_request with the number in the trigger message. Read the title, description, current labels, and changed file patches. If the head commit no longer matches the triggered commit, stop so a newer run can classify it.
  2. If the pull request already has bug, documentation, or enhancement, stop. Keep labels chosen by maintainers or earlier runs.
  3. Choose one label from the primary change supported by the patch:
    • documentation: changes only documentation, examples, or explanatory text, without changing CLI behavior.
    • bug: corrects existing CLI behavior, including installation, update checks, source parsing, agent detection, or security checks.
    • enhancement: adds or intentionally expands CLI behavior, commands, agent support, or integration support.
  4. If the patch is truncated, mixed, or insufficient to classify confidently, stop without adding a label. Do not infer a label from the title alone.
  5. Use add_label once, with the triggering pull request number and the chosen label.

Tips for PR Labeling

  • • Start a fresh session after installing so your agent picks up the new skill.
  • • It is part of a pack with 3 skills. Install only the ones you need with --skill to keep triggers precise.
  • • If two skills overlap, mention the one you want by name.
