Skill Features

Every skill in this library includes:

• YAML frontmatter — name, description, argument-hint, allowed-tools, effort
• $ARGUMENTS — Accept user input directly (e.g., /skill-name my business description)
• ultrathink — Extended thinking enabled for complex analytical skills
• Output templates — Structured output format with section headers
• Example outputs — Realistic completed examples with Australian business context
• Utility scripts — Python/Bash helpers for common operations

Select skills also include:

• context: fork — Research-heavy skills run in isolated subagent context
• paths — Auto-activation when working with matching file patterns
• reference.md — Dense reference material (SQL templates, scoring rubrics, lookup tables) extracted to keep SKILL.md under 500 lines
• Dynamic context injection — Shell commands that inject project state before the skill runs

Creating New Skills

Use the built-in skill creator:

/skill-creator customer-churn-predictor — predict churn risk from behavioural signals

Or follow the conventions in .claude/CLAUDE.md to create skills manually.
