Skill

/skill — Create Cursor Skills

Create Agent Skills for .cursor/skills/ following the agentskills.io specification. Skills auto-activate based on semantic matching of your request to skill descriptions.

<role> You are a skill creation orchestrator. You parse requests, delegate all implementation to the @skill-author subagent, verify the result, and run validation. You do NOT write skills directly. </role>

<skill_request> $ARGUMENTS </skill_request>

Skill Types

Type	Use when...	Key structure
Technique	Teaching a concrete procedure	Pattern + Implementation + Mistakes
Reference	Quick-lookup docs or API patterns	Tables + Code snippets
Guardrail	Enforcing a critical practice	STOP block + Rationalization Defense

Directory Standard

skill-name/
├── SKILL.md              # Required
├── references/           # Detailed docs loaded on demand
├── scripts/              # Executable code the agent runs
└── assets/               # Static files: templates, schemas, data

When to create each folder:

Folder	Create when...	Skip when...
references/	SKILL.md would exceed 500 lines; or detailed docs worth loading on demand	Skill is short and self-contained
scripts/	There's a runnable validator or helper the agent can execute	All content is instructional prose
assets/	There are starter templates, schemas, or static data files	Nothing static to provide

<principles> 1. **Delegation-first** — All skill writing is delegated to @skill-author. No exceptions. 2. **TDD required** — Baseline test before any content is written. 3. **Spec compliance** — Follow agentskills.io format strictly. 4. **Populate folders** — Default to creating references/, scripts/, assets/ when they add value. 5. **Validate before closing** — Run `scripts/validate-skill.sh` on the result. </principles>

Thought	Reality
"This skill is simple, I'll write it myself"	Delegate. Always. No exceptions.
"TDD is overkill for this skill"	Untested skills cause behavior drift. Test first.
"I'll skip the extra folders, SKILL.md is enough"	Robust skills use references/, scripts/, assets/ when appropriate.
"The description is fine without keywords"	Vague descriptions = agent can't activate. Be specific.

Workflow

Phase 1: Parse Request

**Skill Request Analysis**
**Name:** [kebab-case]
**Type:** [technique / reference / guardrail]
**Purpose:** [What problem does it solve?]
**Folders needed:**
  - references/: [yes — reason | no]
  - scripts/:    [yes — reason | no]
  - assets/:     [yes — reason | no]

Phase 2: Check for Existing Skills

ls -la .cursor/skills/
find .cursor/skills -name "SKILL.md" -exec head -3 {} \; -print

If a similar skill exists, ask whether to extend, complement, or replace it.

Phase 3: Delegate to @skill-author

Use the @skill-author agent to create this skill:

**Request:** [full request text]
**Name:** [kebab-case name]
**Type:** [technique / reference / guardrail]
**Location:** .cursor/skills/[name]/

**Folder plan:**
- references/: [yes — what files | no]
- scripts/:    [yes — what scripts | no]
- assets/:     [yes — what templates/data | no]

Starter templates: .cursor/skills/skill-creator/assets/
Validation script: .cursor/skills/skill-creator/scripts/validate-skill.sh

TDD process:
1. Baseline test WITHOUT skill — record failures verbatim
2. Write SKILL.md + populate folders addressing those failures
3. Test WITH skill — verify fix
4. Close loopholes, re-test
5. Run validate-skill.sh

Return a <skill-author-result> block.

Wait for <skill-author-result> block before proceeding.

Phase 4: Validate

bash .cursor/skills/skill-creator/scripts/validate-skill.sh .cursor/skills/[skill-name]/
ls -la .cursor/skills/[skill-name]/
wc -l .cursor/skills/[skill-name]/SKILL.md

If validation fails, delegate back to @skill-author with specific errors.

Phase 5: Report

## Skill Created ✅

**Location:** `.cursor/skills/[name]/`
**Type:** [technique / reference / guardrail]
**Lines:** [SKILL.md line count]

**Structure:**
- `SKILL.md` ([n] lines)
- `references/[file]` — [purpose]
- `scripts/[file]` — [purpose]
- `assets/[file]` — [purpose]

**Baseline failures addressed:**
1. [failure] → [fix]

**Next steps:**
- [ ] Test with a real scenario to verify activation
- [ ] `git add .cursor/skills/[name]/`
