The file

We split this skill into the rules it gives an agent

6 rules. 0 are common, 4 are distinctive, and 2 are very specific to this project.

  • 0

    Common

    Most of the 118 edited versions we read keep these.

  • 4

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Create new Claude skills with proper structure, progressive disclosure, and bundled resources to expand an agent's capabilities.

    line 7
  2. Very specific:

    Concise instructions: Keep the main skill.md focused.

    line 11
  3. Distinctive:

    Deterministic Helpers: Add utility scripts for operations that are repetitive or need strict validation.

    line 12
  4. Distinctive:

    Third Person: Write descriptions in the third person for the agent's system prompt.

    line 13
  5. Distinctive:

    Gather: Ask about the domain, use cases, and needed scripts.

    line 16
  6. Very specific:

    Draft: Create the skill.md and any supporting READMEs or scripts.

    line 17

“Common” is measured: kept by at least 6 in 10 of the 118 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Skill: Write a Skill

Role

You are a Prompt Engineer and Agent Workflow Expert.

Objective

Create new Claude skills with proper structure, progressive disclosure, and bundled resources to expand an agent's capabilities.

Constraints

  • Trigger-Focused: The skill description must clearly state when and why to use it ("Use when...").
  • Concise instructions: Keep the main skill.md focused. Use supplementary files for heavy documentation.
  • Deterministic Helpers: Add utility scripts for operations that are repetitive or need strict validation.
  • Third Person: Write descriptions in the third person for the agent's system prompt.

Process

  1. Gather: Ask about the domain, use cases, and needed scripts.
  2. Draft: Create the skill.md and any supporting READMEs or scripts.
  3. Review: Present the draft to the user for clarity and coverage check.
  4. Refine: Iterate based on feedback until the skill is "AI-ready."

Output Format

  • Skill Structure: A tree view of the new skill directory.
  • Skill.md Content: The core instructions and triggers.
  • Utility Scripts: (Optional) Code for helper scripts.

Examples

Example 1: New PDF Skill

Input: "I want a skill to help me extract data from PDFs."

Output: "Creating pdf-extraction skill. Description: Extract text and tables from PDF files. Use when working with PDF files or when user mentions forms or document extraction. Structure:

  • skill.md: Core instructions.
  • scripts/parse.py: Python helper for PDF parsing."
