self-validating-example

Example skill demonstrating self-validating REST API generation with automatic test execution. Use as a template for creating skills with pre-tool-use validation hooks. Validates Node.js environment and dependencies before generating endpoints.

Why use this skill?

Learn to use the self-validating-example skill for OpenClaw to generate reliable Express API endpoints with automatic unit testing and linting.

What This Skill Does

The self-validating-example skill for OpenClaw is a sophisticated architectural template designed to bridge the gap between AI-generated code and production-ready reliability. Rather than simply emitting code into a vacuum, this skill enforces a strict validation lifecycle for every REST API endpoint generated. It treats the local Node.js environment as a staging area, verifying the existence of Express dependencies before generating routes, and immediately executing automated test suites via Vitest. If the generated code fails type-checking (tsc) or integration tests, the agent receives explicit error feedback, allowing it to perform self-correction loops. This creates a closed-loop development process where the AI "learns" from its own errors in real-time.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/anton-abyzov/sw-self-validating-example Ensure your local environment has Node.js (v18+) and npm installed, as the skill relies on standard project structures like src/routes/ and requires vitest or jest for test execution.

Use Cases

  • Rapid Prototyping: Build CRUD endpoints with embedded verification to ensure your API contract matches your data model.
  • Automated Refactoring: Use the skill to generate code that automatically passes existing linter and type-safety rules in large codebases.
  • CI/CD Pre-flight: Use this for local-first testing where code must be confirmed correct before being committed to version control.
  • Educational Scaffolding: Ideal for teams learning to write test-driven code, as the agent provides the template and forces the necessary test files to exist.

Example Prompts

  1. "Generate a new user management API endpoint that validates email formats and ensures unique usernames, making sure the self-validation loop passes."
  2. "Create a task manager endpoint for POST requests that stores data in a mock database and includes comprehensive unit tests verifying error handling for empty payloads."
  3. "Refactor the existing /profile route to support PATCH requests with strict type validation, ensuring all tests pass through the self-validating-example toolchain."

Tips & Limitations

  • Tip: Keep your tsconfig.json up to date; the skill relies on tsc --noEmit to verify type integrity.
  • Tip: If validation fails repeatedly, check the agent's scratchpad for specific linting errors that might be blocking the test execution phase.
  • Limitation: The skill is currently optimized for Express.js. Porting to other frameworks like Fastify or Koa may require manual configuration tweaks.
  • Limitation: The automatic retry mechanism is capped at three attempts to prevent infinite loops in cases of complex logic failures.
