Skill Creator
Create effective, token-efficient skills that extend Claude's capabilities with specialized workflows, scripts, and domain knowledge.
When to Use
- Creating a new skill from scratch
- Updating or optimizing an existing skill
- Adding references, scripts, or assets to a skill
- Packaging a skill for distribution
- Auditing skill quality (metadata, structure, token efficiency)
Critical Rules
| Rule | Limit |
|------|-------|
| description in frontmatter | < 200 characters, specific triggers, not generic |
| SKILL.md body | < 150 lines |
| Each reference file | < 150 lines (split if larger) |
| No duplication | Info lives in SKILL.md OR references, never both |
| Writing style | Imperative form ("To accomplish X, do Y"), third-person metadata |
| Scripts | Node.js or Python (not bash). Must have tests. Must respect .env hierarchy. |
| Consolidation | Combine related topics into one skill (e.g., mongodb + postgresql → databases) |
Skill Types
| Type | Template | Best For |
|------|----------|----------|
| General | SKILL.md.template | Custom workflows, guidelines |
| Scoring | scoring-skill.md.template | Audit/grade against criteria |
| Fix | fix-skill.md.template | Implement fixes from scoring |
| Generate | generate-skill.md.template | Create new code/content |
| Migrate | migrate-skill.md.template | Version upgrades |

Creation Process
Follow steps in order. See references/creation-workflow.md for detailed guidance.
- Understand — Gather trigger phrases, use cases, concrete examples
- Research — Search web for best practices, existing CLI tools, edge cases
- Plan — Identify scripts (deterministic tasks), references (docs), assets (templates)
- Initialize —
scripts/init_skill.py <skill-name> --path <output-directory> - Edit — Write references/scripts first, then SKILL.md last (see
references/writing-guide.md) - Validate —
scripts/quick_validate.py <path>thenscripts/package_skill.py <path> - Iterate — Use on real tasks → notice gaps → update → re-validate
