What This Skill Does

A guide for writing SKILL.md files that extend agent capabilities on the agentskills.io standard. Covers frontmatter structure, conciseness principles, and freedom-level matching for different task types.

Provides explicit anti-patterns and a freedom-level framework that prevent authors from over-specifying or under-specifying agent behavior.

When to use it

  • Writing a new SKILL.md for a custom agent workflow
  • Updating an existing skill's description to improve activation reliability
  • Teaching an agent a domain-specific process it doesn't already know
  • Deciding how prescriptive skill instructions should be for a given task
  • Splitting a large skill into SKILL.md and references/ for token efficiency

Example Workflow

Here's how your AI assistant might use this skill in practice.

INPUT

User asks: Write a SKILL.md for a code review workflow

AGENT
  1. 1Identify the task type and determine the appropriate freedom level (high, medium, or low)
  2. 2Draft frontmatter with name, description, and metadata fields
  3. 3Write instructions matching the chosen freedom level, using scripts or pseudocode where consistency is required
  4. 4Add directory structure if scripts or reference documents are needed
  5. 5Review for token efficiency and remove any explanations the agent already knows
OUTPUT

A complete SKILL.md file with frontmatter, structured instructions, and guardrails appropriate for the code review workflow
