What it does

When installed, the agent walks through a fixed checklist of six phases on your code project: it runs the build, type checker, linter and test suite with coverage, scans for leaked secrets and stray console.log lines, and reviews the git diff of changed files. It then produces a short PASS/FAIL report and a verdict on whether the work is ready for a pull request. The instructions are in Spanish, and the commands shown are for Node/TypeScript and Python projects.

Great for

  • Developers finishing a feature who want a consistent pre-PR check run by the agent
  • Teams using Claude Code who want the same quality gates applied each session
  • Developers working in Spanish who want the checklist in that language

Skip it if

  • Non-developers, since it assumes a code project with npm/pnpm, git and build tools installed; it does nothing useful outside a codebase
  • Projects using other languages or tooling, because the commands cover only JavaScript/TypeScript and Python, and the agent must adapt them itself
  • Anyone relying on it as a real security audit: the secret check is a simple grep for 'sk-' and 'api_key' and can miss or wrongly flag secrets

Try asking

  • “Run the verification loop on my changes before I open a PR”
  • “Check whether this branch is ready to merge: build, types, lint and tests”
  • “Do a verification pass after refactoring the payments module”
  • “/verify”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Review the commands the agent runs before it executes them, since they run directly in your project folder and the skill does not restrict them
  • Adjust the commands to your project's real scripts; the skill assumes npm run build, lint and test exist
  • Treat the secret scan as a first pass only and use a dedicated secret scanner for anything sensitive
