Skill Activator: Make Your Skills Work

Purpose

Ensure skills are discovered and invoked at the right time by designing effective triggers and descriptions.

Why Skills Don't Get Called

Problem	Cause	Solution
Never invoked	Description doesn't match user language	Add trigger phrases
Invoked at wrong time	Description too broad	Add "Use when" / "Don't use when"
Invoked but ignored	Low relevance signal	Make description more specific

The Skill Description Formula

code

[What it does] + [When to use] + [Trigger phrases]

Bad Example

yaml

description: Code review skill

•Too vague
•No trigger phrases
•Doesn't say when to use

Good Example

yaml

description: >
  Perform structured code review with security, performance, and
  maintainability checks. Use when reviewing PRs, before merging,
  or when user says "review", "check this code", or "find issues".

•Specific about what it does
•Clear when to use
•Multiple trigger phrases

Trigger Phrase Design

Match User Language

Think about how users actually ask for things:

User Says	Skill Should Match
"review this"	code-review
"check for bugs"	code-review, debug
"is this secure?"	security-review
"make it faster"	performance-optimization
"clean this up"	refactoring

Include Variations

yaml

description: >
  ... Use when user says "review", "check", "look at",
  "find issues", "is this good", or "before merging".

The Description Template

markdown

---
name: {skill-name}
description: >
  {One sentence: what this skill does}.
  Use when {specific situations}.
  Trigger phrases: "{phrase1}", "{phrase2}", "{phrase3}".
  Don't use when {exclusions}.
---

Complete Example

markdown

---
name: api-design
description: >
  Design RESTful APIs following best practices for naming,
  versioning, and error handling. Use when creating new endpoints,
  reviewing API design, or planning API changes. Trigger phrases:
  "design API", "new endpoint", "REST structure", "API review".
  Don't use for GraphQL or internal service communication.

Skill Audit Checklist

Review each skill against this checklist:

Discoverability

• Description is under 200 characters (for readability)
• First sentence clearly states purpose
• Contains 3+ trigger phrases
• Trigger phrases match real user language

Specificity

• "Use when" is specific, not generic
• "Don't use when" excludes wrong contexts
• Doesn't overlap significantly with other skills

Invocation Testing

• Tested with natural language requests
• Verified it's called in expected scenarios
• Verified it's NOT called in wrong scenarios

Skill Categories and Conventions

By Invocation Style

Style	`disable-model-invocation`	When to Use
Auto-invoked	`false` or omitted	Should trigger automatically based on context
Manual only	`true`	User must explicitly call with `/skill-name`

When to Use Manual-Only

•Destructive operations (delete, reset)
•Long-running processes
•Operations with side effects
•User preference workflows

Debugging Skill Invocation

Skill Not Being Called?

•Check description - Does it match how users ask?
•Check triggers - Are trigger phrases natural?
•Check competition - Is another skill taking priority?
•Test directly - Call with /skill-name to verify it works

Skill Called at Wrong Time?

•Add exclusions - "Don't use when..."
•Narrow scope - Make "Use when" more specific
•Split skill - Maybe it's doing too many things

Test Skill Matching

Ask Claude: "Which skill would you use for [scenario]?"

Force Skill Invocation

code

/skill-name [arguments]

Integration with Other Skills

•Use intent-first to clarify what the user needs
•Use delegation-triggers to decide if a skill or agent is appropriate
•Then activate the right skill based on the clarified intent
