Skill Manager

Manage Claude Code skills: create, improve, list, and analyze.

Usage

/skill-manager create [skill-name]   # Create a new skill
/skill-manager improve [skill-name]  # Improve an existing skill
/skill-manager list                  # List all skills
/skill-manager [skill-name]          # Analyze/improve (default)

Parse $ARGUMENTS to determine the action. If no action is specified, default to improve if a skill name is given.

Current Skills

Global skills: !ls -1 ~/.claude/skills/ 2>/dev/null || echo "(none)"

Project skills: !ls -1 .claude/skills/ 2>/dev/null || echo "(none)"

---

Action: create

Create a new skill from scratch.

Workflow

1. Gather Requirements via AskUserQuestion:

   • Skill name (kebab-case)
   • Purpose and description
   • Trigger phrases (Japanese + English)
   • Required tools
   • Location: ~/.claude/skills/ (global) or .claude/skills/ (project)

2. Create Directory Structure:

   skill-name/
   ├── SKILL.md              # Required
   ├── references/           # Optional: Reference docs
   ├── templates/            # Optional: Template files
   └── examples/             # Optional: Usage examples
   

3. Write SKILL.md using the template in templates/basic.md or templates/advanced.md

4. Report Success: Show the invoke command /skill-name

---

Action: improve

Improve an existing skill.

Workflow

1. Locate the Skill:

   • Check ~/.claude/skills/{skill-name}/SKILL.md
   • Check .claude/skills/{skill-name}/SKILL.md
   • If not found, list available skills and ask user

2. Analyze Current State:

   • Read SKILL.md and all related files
   • Identify issues:
     • Vague or missing trigger phrases
     • Overly broad or missing tool restrictions
     • Unclear instructions
     • Missing error handling
     • No examples

3. Suggest Improvements via AskUserQuestion:

   • Present findings and recommendations
   • Ask what the user wants to improve:
     • Trigger phrases (more specific, bilingual)
     • Instructions (clearer workflow)
     • Tool restrictions (security)
     • Examples (usage clarity)
     • Structure (add references/, templates/)

4. Apply Changes: Edit SKILL.md and related files

5. Report Changes: Summarize what was improved

---

Action: list

List all available skills with their status.

Workflow

1. Scan Directories:

   • ~/.claude/skills/ (global)
   • .claude/skills/ (project-local)

2. For Each Skill, Report:

   • Name and version
   • Description (first line)
   • Trigger phrases count
   • Allowed tools
   • Location (global/project)

3. Output Format:

   📁 Global Skills (~/.claude/skills/)
   ├── skill-name (v1.0.0) - Description
   │   └── Triggers: "phrase1", "phrase2"
   
   📁 Project Skills (.claude/skills/)
   └── (none)

Best Practices

1. Specific triggers: Include exact phrases users will say (quoted)
2. Bilingual: Japanese + English trigger phrases
3. Restrict tools: Use allowed-tools for security
4. Keep SKILL.md concise: Put reference docs in references/
5. Version your skills: Update version on changes
6. Test triggers: Verify the skill activates on expected phrases
