SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Skill Writing provides a structured, test-driven approach to creating, refactoring, and validating agent instruction modules (SKILL.md) so agents follow desired behavior with documented guardrails and rationalizations.

Core Features & Use Cases

  • TDD-driven skill creation: write a failing scenario, then implement and refactor for compliance.
  • Standardized frontmatter and prompts: ensure consistent loading and activation across projects.
  • Debug and optimize: improve prompt structure, descriptions, and rationale to reduce drift and misbehavior.
  • Use Cases: when you need to create a new skill, refine an existing one, or improve agent instruction compliance and test coverage.

Quick Start

Document and implement a test-driven skill for agent prompt formatting, starting from a failing scenario and iterating until the agent complies.

FAQPage Schema
How do I write agent instructions that prevent prompt drift?▼

Prevent prompt drift by creating SKILL.md modules using a test-driven approach, writing a failing scenario first, then implementing and refactoring the agent instructions until compliance is achieved.

Why does my agent ignore instructions in my prompt?▼

Your agent might ignore instructions if the SKILL.md module lacks explicit guardrails and rationalizations; debugging and optimizing the prompt structure with a test-driven approach resolves this non-compliance.

What is test-driven development for AI agent skills?▼

Test-driven development for AI agent skills is a structured approach where you write a failing scenario first, then implement and refactor the SKILL.md module until the agent reliably follows the desired behavior with documented guardrails.

How do I structure a SKILL.md file for reliable prompt handling?▼

Structure a SKILL.md file by including frontmatter with a name and description, a concise operational description, and guardrails with explicit failure handling to ensure reliable prompt loading and activation across projects.

What's the best way to refactor existing agent instructions?▼

The best way to refactor existing agent instructions is to apply a test-driven approach: write failing scenarios for current behavior, then refine the SKILL.md prompt structure, descriptions, and rationale to improve compliance and test coverage.

Do I need guardrails for every agent instruction module?▼

Yes, you need guardrails with explicit failure handling for every agent instruction module to ensure reliable prompt handling, reduce misbehavior, and maintain consistent activation across projects.
