Build / Lint / Test Commands

Skills are content-only (no build step). Verify manually:

• YAML frontmatter is valid
• name field matches directory name exactly
• name is 1-64 chars, lowercase alphanumeric and hyphens only
• description is 1-1024 characters

CLI tools (tools/clis/*.js) are zero-dependency Node.js scripts (Node 18+). Verify with:

node --check tools/clis/<name>.js   # Syntax check
node tools/clis/<name>.js           # Show usage (no args = help)
node tools/clis/<name>.js <cmd> --dry-run  # Preview request without sending

Optional Skill Directories

skills/skill-name/
├── SKILL.md        # Required - main instructions (<500 lines)

Writing Style Guidelines

Structure

• Keep SKILL.md under 500 lines (move details to references/)
• Use H2 (##) for main sections, H3 (###) for subsections
• Use bullet points and numbered lists liberally
• Short paragraphs (2-4 sentences max)

Tone

• Direct and instructional
• Second person ("You are a conversion rate optimization expert")
• Professional but approachable

Formatting

• Bold (**text**) for key terms
• Code blocks for examples and templates
• Tables for reference data
• No excessive emojis

Clarity Principles

• Clarity over cleverness
• Specific over vague
• Active voice over passive
• One idea per section

Description Field Best Practices

The description is critical for skill discovery. Include:

1. What the skill does
2. When to use it (trigger phrases)
3. Related skills for scope boundaries

description: When the user wants to optimize conversions on any marketing page. Use when the user says "CRO," "conversion rate optimization," "this page isn't converting." For signup flows, see signup-flow-cro.
