Skill Crafter

Skill Crafter

You produce skills that are immediately useful, auto-discoverable, and follow the exact conventions from the official Grok Build skills guide.

Required Output Format

Every skill you create must contain:

---
name: kebab-case-name
description: >
  One or two sentence description that is specific enough for automatic
  invocation. Include example trigger phrases the user might say.
when-to-use: Optional but recommended — explicit trigger phrases.
argument-hint: "<example usage>"
metadata:
  short-description: "Very short label (optional)"
---

# Human Friendly Title

Intro paragraph.

## Steps (or Usage / Workflow)

1. Numbered, concrete actions.
2. Each step should mention tools by name when relevant
   (`read_file`, `grep`, `spawn_subagent`, `run_terminal_command`, `write`, etc.).
3. Include success criteria or "what good looks like".

## Principles / Important Notes (recommended)

- Anti-hallucination, safety, or verification rules.
- References to other skills or AGENTS.md sections when useful.

Creation Process

1. Clarify the workflow the skill should capture.

   • Ask for (or infer) the exact trigger phrases users will say.
   • Identify the primary tools the skill will use.

2. Write excellent description text.

   • It must be specific. Bad: "Helps with commits". Good: "Create well-formatted git commits following conventional commit standards. Use when the user wants to commit changes or asks for /commit."

3. Structure the body:

   • Start with a short purpose.
   • Use numbered steps (the agent loves ordered procedures).
   • Include verbatim prompts, command examples, or output formats where the skill needs precision.
   • Add "Important Principles" or "Verification" sections for non-trivial skills.

4. Make it self-contained but reference official docs or other skills when relevant (e.g. "follow the todo discipline in AGENTS.md").

5. After writing the file, suggest how the user can test it:

   • /skills <new-name>
   • Run a small task that should trigger it automatically.

Quality Checklist (run this mentally before finishing)

• Frontmatter has name (lowercase, hyphens) and a rich description
• Description contains realistic user phrases that would cause auto-invocation
• Steps are numbered and reference concrete tool names
• No vague advice ("be careful") — specific rules instead
• Under 4000 characters when possible (skills should be focused)
• Includes at least one realistic example in the body or description

Scope

• --project (default for this repo) → write into .grok/skills/<name>/
• --user → write into the user's global ~/.grok/skills/<name>/

This skill was used conceptually while creating the other skills in this repository (project-auditor, readiness-scorer).

Ship skills that make future Grok sessions dramatically better.
