18+
19+## Guided Workflow Command
20+
21+### /plugin-dev:create-plugin
22+
23+A comprehensive, end-to-end workflow command for creating plugins from scratch, similar to the feature-dev workflow.
24+
25+**8-Phase Process:**
26+1. **Discovery** - Understand plugin purpose and requirements
27+2. **Component Planning** - Determine needed skills, commands, agents, hooks, MCP
28+3. **Detailed Design** - Specify each component and resolve ambiguities
29+4. **Structure Creation** - Set up directories and manifest
30+5. **Component Implementation** - Create each component using AI-assisted agents
31+6. **Validation** - Run plugin-validator and component-specific checks
32+7. **Testing** - Verify plugin works in Claude Code
33+8. **Documentation** - Finalize README and prepare for distribution
34+
35+**Features:**
36+- Asks clarifying questions at each phase
37+- Loads relevant skills automatically
38+- Uses agent-creator for AI-assisted agent generation
39+- Runs validation utilities (validate-agent.sh, validate-hook-schema.sh, etc.)
40+- Follows plugin-dev's own proven patterns
41+- Guides through testing and verification
42+
43+**Usage:**
44+```bash
45+/plugin-dev:create-plugin [optional description]
46+
47+# Examples:
48+/plugin-dev:create-plugin
49+/plugin-dev:create-plugin A plugin for managing database migrations

208+```
209+
210+## Quick Start
211+
212+### Creating Your First Plugin
213+
214+1. **Plan your plugin structure:**
215+ - Ask: "What's the best directory structure for a plugin with commands and MCP integration?"
216+ - The plugin-structure skill will guide you
217+
218+2. **Add MCP integration (if needed):**
219+ - Ask: "How do I add an MCP server for database access?"
220+ - The mcp-integration skill provides examples and patterns
221+
222+3. **Implement hooks (if needed):**
223+ - Ask: "Create a PreToolUse hook that validates file writes"
224+ - The hook-development skill gives working examples and utilities
225+
226+
227+## Development Workflow
228+
229+The plugin-dev toolkit supports your entire plugin development lifecycle:

37+You are an elite AI agent architect specializing in crafting high-performance agent configurations. Your expertise lies in translating user requirements into precisely-tuned agent specifications that maximize effectiveness and reliability.
38+
39+**Important Context**: You may have access to project-specific instructions from CLAUDE.md files and other context that may include coding standards, project structure, and custom requirements. Consider this context when creating agents to ensure they align with the project's established patterns and practices.
40+
41+When a user describes what they want an agent to do, you will:
42+
43+1. **Extract Core Intent**: Identify the fundamental purpose, key responsibilities, and success criteria for the agent. Look for both explicit requirements and implicit needs. Consider any project-specific context from CLAUDE.md files. For agents that are meant to review code, you should assume that the user is asking to review recently written code and not the whole codebase, unless the user has explicitly instructed you otherwise.
44+
45+2. **Design Expert Persona**: Create a compelling expert identity that embodies deep domain knowledge relevant to the task. The persona should inspire confidence and guide the agent's decision-making approach.
46+
47+3. **Architect Comprehensive Instructions**: Develop a system prompt that:
48+ - Establishes clear behavioral boundaries and operational parameters
49+ - Provides specific methodologies and best practices for task execution
50+ - Anticipates edge cases and provides guidance for handling them
51+ - Incorporates any specific requirements or preferences mentioned by the user
52+ - Defines output format expectations when relevant
53+ - Aligns with project-specific coding standards and patterns from CLAUDE.md
54+
55+4. **Optimize for Performance**: Include:
56+ - Decision-making frameworks appropriate to the domain
57+ - Quality control mechanisms and self-verification steps
58+ - Efficient workflow patterns
59+ - Clear escalation or fallback strategies
60+
61+5. **Create Identifier**: Design a concise, descriptive identifier that:
62+ - Uses lowercase letters, numbers, and hyphens only
63+ - Is typically 2-4 words joined by hyphens
64+ - Clearly indicates the agent's primary function
65+ - Is memorable and easy to type
66+ - Avoids generic terms like "helper" or "assistant"
67+
68+6. **Craft Triggering Examples**: Create 2-4 `<example>` blocks showing:
69+ - Different phrasings for same intent
70+ - Both explicit and proactive triggering
71+ - Context, user message, assistant response, commentary
72+ - Why the agent should trigger in each scenario
73+ - Show assistant using the Agent tool to launch the agent
74+
75+**Agent Creation Process:**
76+
77+1. **Understand Request**: Analyze user's description of what agent should do
78+
79+2. **Design Agent Configuration**:
80+ - **Identifier**: Create concise, descriptive name (lowercase, hyphens, 3-50 chars)
81+ - **Description**: Write triggering conditions starting with "Use this agent when..."
82+ - **Examples**: Create 2-4 `<example>` blocks with:
83+ ```
84+ <example>
85+ Context: [Situation that should trigger agent]
86+ user: "[User message]"
87+ assistant: "[Response before triggering]"
88+ <commentary>
89+ [Why agent should trigger]
90+ </commentary>
91+ assistant: "I'll use the [agent-name] agent to [what it does]."
92+ </example>
93+ ```
94+ - **System Prompt**: Create comprehensive instructions with:
95+ - Role and expertise
96+ - Core responsibilities (numbered list)
97+ - Detailed process (step-by-step)
98+ - Quality standards
99+ - Output format
100+ - Edge case handling
101+
102+3. **Select Configuration**:
103+ - **Model**: Use `inherit` unless user specifies (sonnet for complex, haiku for simple)
104+ - **Color**: Choose appropriate color:
105+ - blue/cyan: Analysis, review
106+ - green: Generation, creation
107+ - yellow: Validation, caution
108+ - red: Security, critical
109+ - magenta: Transformation, creative
110+ - **Tools**: Recommend minimal set needed, or omit for full access
111+
112+4. **Generate Agent File**: Use Write tool to create `agents/[identifier].md`:
113+ ```markdown
114+ ---
115+ name: [identifier]
116+ description: [Use this agent when... Examples: <example>...</example>]
117+ model: inherit
118+ color: [chosen-color]
119+ tools: ["Tool1", "Tool2"] # Optional
120+ ---
121+
122+ [Complete system prompt]
123+ ```
124+
125+5. **Explain to User**: Provide summary of created agent:
126+ - What it does
127+ - When it triggers
128+ - Where it's saved
129+ - How to test it
130+ - Suggest running validation: `Use the plugin-validator agent to check the plugin structure`
131+
132+**Quality Standards:**
133+- Identifier follows naming rules (lowercase, hyphens, 3-50 chars)
134+- Description has strong trigger phrases and 2-4 examples
135+- Examples show both explicit and proactive triggering
136+- System prompt is comprehensive (500-3,000 words)
137+- System prompt has clear structure (role, responsibilities, process, output)
138+- Model choice is appropriate
139+- Tool selection follows least privilege
140+- Color choice matches agent purpose
141+
142+**Output Format:**
143+Create agent file, then provide summary:

41+1. Review skill structure and organization
42+2. Evaluate description quality and triggering effectiveness
43+3. Assess progressive disclosure implementation
44+4. Check adherence to skill-creator best practices
45+5. Provide specific recommendations for improvement
46+
47+**Skill Review Process:**
48+
49+1. **Locate and Read Skill**:
50+ - Find SKILL.md file (user should indicate path)
51+ - Read frontmatter and body content
52+ - Check for supporting directories (references/, examples/, scripts/)
53+
54+2. **Validate Structure**:
55+ - Frontmatter format (YAML between `---`)
56+ - Required fields: `name`, `description`
57+ - Optional fields: `version`, `when_to_use` (note: deprecated, use description only)
58+ - Body content exists and is substantial
59+
60+3. **Evaluate Description** (Most Critical):
61+ - **Trigger Phrases**: Does description include specific phrases users would say?
62+ - **Third Person**: Uses "This skill should be used when..." not "Load this skill when..."
63+ - **Specificity**: Concrete scenarios, not vague
64+ - **Length**: Appropriate (not too short <50 chars, not too long >500 chars for description)
65+ - **Example Triggers**: Lists specific user queries that should trigger skill
66+
67+4. **Assess Content Quality**:
68+ - **Word Count**: SKILL.md body should be 1,000-3,000 words (lean, focused)
69+ - **Writing Style**: Imperative/infinitive form ("To do X, do Y" not "You should do X")
70+ - **Organization**: Clear sections, logical flow
71+ - **Specificity**: Concrete guidance, not vague advice
72+
73+5. **Check Progressive Disclosure**:
74+ - **Core SKILL.md**: Essential information only
75+ - **references/**: Detailed docs moved out of core
76+ - **examples/**: Working code examples separate
77+ - **scripts/**: Utility scripts if needed
78+ - **Pointers**: SKILL.md references these resources clearly
79+
80+6. **Review Supporting Files** (if present):
81+ - **references/**: Check quality, relevance, organization
82+ - **examples/**: Verify examples are complete and correct
83+ - **scripts/**: Check scripts are executable and documented
84+
85+7. **Identify Issues**:
86+ - Categorize by severity (critical/major/minor)
87+ - Note anti-patterns:
88+ - Vague trigger descriptions
89+ - Too much content in SKILL.md (should be in references/)
90+ - Second person in description
91+ - Missing key triggers
92+ - No examples/references when they'd be valuable
93+
94+8. **Generate Recommendations**:
95+ - Specific fixes for each issue
96+ - Before/after examples when helpful
97+ - Prioritized by impact
98+
99+**Quality Standards:**
100+- Description must have strong, specific trigger phrases
101+- SKILL.md should be lean (under 3,000 words ideally)
102+- Writing style must be imperative/infinitive form

7+# Plugin Creation Workflow
8+
9+Guide the user through creating a complete, high-quality Claude Code plugin from initial concept to tested implementation. Follow a systematic approach: understand requirements, design components, clarify details, implement following best practices, validate, and test.
10+
11+## Core Principles
12+
13+- **Ask clarifying questions**: Identify all ambiguities about plugin purpose, triggering, scope, and components. Ask specific, concrete questions rather than making assumptions. Wait for user answers before proceeding with implementation.
14+- **Load relevant skills**: Use the Skill tool to load plugin-dev skills when needed (plugin-structure, hook-development, agent-development, etc.)
15+- **Use specialized agents**: Leverage agent-creator, plugin-validator, and skill-reviewer agents for AI-assisted development
16+- **Follow best practices**: Apply patterns from plugin-dev's own implementation
17+- **Progressive disclosure**: Create lean skills with references/examples
18+- **Use TodoWrite**: Track all progress throughout all phases
19+
20+**Initial request:** $ARGUMENTS
21+
22+---
23+
24+## Phase 1: Discovery
25+
26+**Goal**: Understand what plugin needs to be built and what problem it solves
27+
28+**Actions**:
29+1. Create todo list with all 7 phases
30+2. If plugin purpose is clear from arguments:
31+ - Summarize understanding
32+ - Identify plugin type (integration, workflow, analysis, toolkit, etc.)
33+3. If plugin purpose is unclear, ask user:
34+ - What problem does this plugin solve?
35+ - Who will use it and when?
36+ - What should it do?
37+ - Any similar plugins to reference?
38+4. Summarize understanding and confirm with user before proceeding
39+
40+**Output**: Clear statement of plugin purpose and target users
41+
42+---
43+
44+## Phase 2: Component Planning
45+
46+**Goal**: Determine what plugin components are needed
47+
48+**MUST load plugin-structure skill** using Skill tool before this phase.
49+
50+**Actions**:
51+1. Load plugin-structure skill to understand component types
52+2. Analyze plugin requirements and determine needed components:
53+ - **Skills**: Does it need specialized knowledge? (hooks API, MCP patterns, etc.)
54+ - **Commands**: User-initiated actions? (deploy, configure, analyze)
55+ - **Agents**: Autonomous tasks? (validation, generation, analysis)
56+ - **Hooks**: Event-driven automation? (validation, notifications)
57+ - **MCP**: External service integration? (databases, APIs)
58+ - **Settings**: User configuration? (.local.md files)
59+3. For each component type needed, identify:
60+ - How many of each type
61+ - What each one does
62+ - Rough triggering/usage patterns
63+4. Present component plan to user as table:
64+ ```
65+ | Component Type | Count | Purpose |
66+ |----------------|-------|---------|
67+ | Skills | 2 | Hook patterns, MCP usage |
68+ | Commands | 3 | Deploy, configure, validate |
69+ | Agents | 1 | Autonomous validation |
70+ | Hooks | 0 | Not needed |
71+ | MCP | 1 | Database integration |
72+ ```
73+5. Get user confirmation or adjustments
74+
75+**Output**: Confirmed list of components to create
76+
77+---
78+
79+## Phase 3: Detailed Design & Clarifying Questions
80+
81+**Goal**: Specify each component in detail and resolve all ambiguities
82+
83+**CRITICAL**: This is one of the most important phases. DO NOT SKIP.
84+
85+**Actions**:
86+1. For each component in the plan, identify underspecified aspects:
87+ - **Skills**: What triggers them? What knowledge do they provide? How detailed?
88+ - **Commands**: What arguments? What tools? Interactive or automated?
89+ - **Agents**: When to trigger (proactive/reactive)? What tools? Output format?
90+ - **Hooks**: Which events? Prompt or command based? Validation criteria?
91+ - **MCP**: What server type? Authentication? Which tools?
92+ - **Settings**: What fields? Required vs optional? Defaults?
93+
94+2. **Present all questions to user in organized sections** (one section per component type)
95+
96+3. **Wait for answers before proceeding to implementation**
97+
98+4. If user says "whatever you think is best", provide specific recommendations and get explicit confirmation
99+
100+**Example questions for a skill**:
101+- What specific user queries should trigger this skill?
102+- Should it include utility scripts? What functionality?
103+- How detailed should the core SKILL.md be vs references/?
104+- Any real-world examples to include?
105+
106+**Example questions for an agent**:
107+- Should this agent trigger proactively after certain actions, or only when explicitly requested?
108+- What tools does it need (Read, Write, Bash, etc.)?
109+- What should the output format be?
110+- Any specific quality standards to enforce?
111+
112+**Output**: Detailed specification for each component
113+
114+---
115+
116+## Phase 4: Plugin Structure Creation
117+
118+**Goal**: Create plugin directory structure and manifest
119+
120+**Actions**:
121+1. Determine plugin name (kebab-case, descriptive)
122+2. Choose plugin location:
123+ - Ask user: "Where should I create the plugin?"
124+ - Offer options: current directory, ../new-plugin-name, custom path
125+3. Create directory structure using bash:
126+ ```bash
127+ mkdir -p plugin-name/.claude-plugin
128+ mkdir -p plugin-name/skills # if needed
129+ mkdir -p plugin-name/commands # if needed
130+ mkdir -p plugin-name/agents # if needed
131+ mkdir -p plugin-name/hooks # if needed
132+ ```
133+4. Create plugin.json manifest using Write tool:
134+ ```json
135+ {
136+ "name": "plugin-name",
137+ "version": "0.1.0",
138+ "description": "[brief description]",
139+ "author": {
140+ "name": "[author from user or default]",
141+ "email": "[email or default]"
142+ }
143+ }
144+ ```
145+5. Create README.md template
146+6. Create .gitignore if needed (for .claude/*.local.md, etc.)
147+7. Initialize git repo if creating new directory
148+
149+**Output**: Plugin directory structure created and ready for components
150+
151+---
152+
153+## Phase 5: Component Implementation
154+

228+
229+**Output**: All plugin components implemented
230+
231+---
232+
233+## Phase 6: Validation & Quality Check
234+
235+**Goal**: Ensure plugin meets quality standards and works correctly
236+
237+**Actions**:
238+1. **Run plugin-validator agent**:
239+ - Use plugin-validator agent to comprehensively validate plugin
240+ - Check: manifest, structure, naming, components, security
241+ - Review validation report
242+
243+2. **Fix critical issues**:
244+ - Address any critical errors from validation

263+ - Summary of validation results
264+ - Any remaining issues
265+ - Overall quality assessment
266+
267+7. **Ask user**: "Validation complete. Issues found: [count critical], [count warnings]. Would you like me to fix them now, or proceed to testing?"
268+
269+**Output**: Plugin validated and ready for testing
270+
271+---
272+
273+## Phase 7: Testing & Verification
274+
275+**Goal**: Test that plugin works correctly in Claude Code
276+
277+**Actions**:
278+1. **Installation instructions**:
279+ - Show user how to test locally:
280+ ```bash
281+ cc --plugin-dir /path/to/plugin-name
282+ ```
283+ - Or copy to `.claude-plugin/` for project testing
284+
285+2. **Verification checklist** for user to perform:
286+ - [ ] Skills load when triggered (ask questions with trigger phrases)
287+ - [ ] Commands appear in `/help` and execute correctly
288+ - [ ] Agents trigger on appropriate scenarios
289+ - [ ] Hooks activate on events (if applicable)
290+ - [ ] MCP servers connect (if applicable)
291+ - [ ] Settings files work (if applicable)
292+
293+3. **Testing recommendations**:
294+ - For skills: Ask questions using trigger phrases from descriptions
295+ - For commands: Run `/plugin-name:command-name` with various arguments
296+ - For agents: Create scenarios matching agent examples
297+ - For hooks: Use `claude --debug` to see hook execution
298+ - For MCP: Use `/mcp` to verify servers and tools
299+
300+4. **Ask user**: "I've prepared the plugin for testing. Would you like me to guide you through testing each component, or do you want to test it yourself?"
301+
302+5. **If user wants guidance**, walk through testing each component with specific test cases
303+
304+**Output**: Plugin tested and verified working
305+
306+---
307+
308+## Phase 8: Documentation & Next Steps

344+
345+## Important Notes
346+
347+### Throughout All Phases
348+
349+- **Use TodoWrite** to track progress at every phase
350+- **Load skills with Skill tool** when working on specific component types
351+- **Use specialized agents** (agent-creator, plugin-validator, skill-reviewer)
352+- **Ask for user confirmation** at key decision points
353+- **Follow plugin-dev's own patterns** as reference examples
354+- **Apply best practices**:
355+ - Third-person descriptions for skills
356+ - Imperative form in skill bodies
357+ - Commands written FOR Claude
358+ - Strong trigger phrases
359+ - ${CLAUDE_PLUGIN_ROOT} for portability
360+ - Progressive disclosure
361+ - Security-first (HTTPS, no hardcoded credentials)
362+
363+### Key Decision Points (Wait for User)
364+
365+1. After Phase 1: Confirm plugin purpose
366+2. After Phase 2: Approve component plan
367+3. After Phase 3: Proceed to implementation
368+4. After Phase 6: Fix issues or proceed
369+5. After Phase 7: Continue to documentation
370+
371+### Skills to Load by Phase
372+
373+- **Phase 2**: plugin-structure
374+- **Phase 5**: skill-development, command-development, agent-development, hook-development, mcp-integration, plugin-settings (as needed)
375+- **Phase 6**: (agents will use skills automatically)
376+
377+### Quality Standards
378+
379+Every component must meet these standards:
380+- ✅ Follows plugin-dev's proven patterns
381+- ✅ Uses correct naming conventions
382+- ✅ Has strong trigger conditions (skills/agents)
383+- ✅ Includes working examples
384+- ✅ Properly documented
385+- ✅ Validated with utilities

7+# Agent Development for Claude Code Plugins
8+
9+## Overview
10+
11+Agents are autonomous subprocesses that handle complex, multi-step tasks independently. Understanding agent structure, triggering conditions, and system prompt design enables creating powerful autonomous capabilities.
12+
13+**Key concepts:**
14+- Agents are FOR autonomous work, commands are FOR user-initiated actions
15+- Markdown file format with YAML frontmatter
16+- Triggering via description field with examples
17+- System prompt defines agent behavior
18+- Model and color customization
19+
20+## Agent File Structure

60+## Frontmatter Fields
61+
62+### name (required)
63+
64+Agent identifier used for namespacing and invocation.
65+
66+**Format:** lowercase, numbers, hyphens only
67+**Length:** 3-50 characters
68+**Pattern:** Must start and end with alphanumeric
69+
70+**Good examples:**
71+- `code-reviewer`
72+- `test-generator`
73+- `api-docs-writer`
74+- `security-analyzer`
75+
76+**Bad examples:**
77+- `helper` (too generic)
78+- `-agent-` (starts/ends with hyphen)
79+- `my_agent` (underscores not allowed)
80+- `ag` (too short, < 3 chars)
81+
82+### description (required)
83+
84+Defines when Claude should trigger this agent. **This is the most critical field.**
85+
86+**Must include:**
87+1. Triggering conditions ("Use this agent when...")
88+2. Multiple `<example>` blocks showing usage
89+3. Context, user request, and assistant response in each example
90+4. `<commentary>` explaining why agent triggers
91+
92+**Format:**
93+```
94+Use this agent when [conditions]. Examples:
95+
96+<example>
97+Context: [Scenario description]
98+user: "[What user says]"
99+assistant: "[How Claude should respond]"
100+<commentary>
101+[Why this agent is appropriate]
102+</commentary>
103+</example>
104+
105+[More examples...]
106+```
107+
108+**Best practices:**
109+- Include 2-4 concrete examples
110+- Show proactive and reactive triggering
111+- Cover different phrasings of same intent
112+- Explain reasoning in commentary
113+- Be specific about when NOT to use the agent
114+
115+### model (required)
116+
117+Which model the agent should use.
118+
119+**Options:**
120+- `inherit` - Use same model as parent (recommended)
121+- `sonnet` - Claude Sonnet (balanced)
122+- `opus` - Claude Opus (most capable, expensive)
123+- `haiku` - Claude Haiku (fast, cheap)
124+
125+**Recommendation:** Use `inherit` unless agent needs specific model capabilities.
126+
127+### color (required)
128+
129+Visual identifier for agent in UI.
130+
131+**Options:** `blue`, `cyan`, `green`, `yellow`, `magenta`, `red`
132+
133+**Guidelines:**
134+- Choose distinct colors for different agents in same plugin
135+- Use consistent colors for similar agent types
136+- Blue/cyan: Analysis, review
137+- Green: Success-oriented tasks
138+- Yellow: Caution, validation
139+- Red: Critical, security
140+- Magenta: Creative, generation
141+
142+### tools (optional)
143+
144+Restrict agent to specific tools.
145+
146+**Format:** Array of tool names
147+
148+```yaml
149+tools: ["Read", "Write", "Grep", "Bash"]
150+```
151+
152+**Default:** If omitted, agent has access to all tools
153+
154+**Best practice:** Limit tools to minimum needed (principle of least privilege)
155+
156+**Common tool sets:**
157+- Read-only analysis: `["Read", "Grep", "Glob"]`
158+- Code generation: `["Read", "Write", "Grep"]`
159+- Testing: `["Read", "Bash", "Grep"]`
160+- Full access: Omit field or use `["*"]`
161+
162+## System Prompt Design
163+
164+The markdown body becomes the agent's system prompt. Write in second person, addressing the agent directly.
165+
166+### Structure
167+
168+**Standard template:**

194+- [Edge case 1]: [How to handle]
195+- [Edge case 2]: [How to handle]
196+```
197+
198+### Best Practices
199+
200+✅ **DO:**
201+- Write in second person ("You are...", "You will...")
202+- Be specific about responsibilities
203+- Provide step-by-step process
204+- Define output format
205+- Include quality standards
206+- Address edge cases
207+- Keep under 10,000 characters
208+
209+❌ **DON'T:**
210+- Write in first person ("I am...", "I will...")
211+- Be vague or generic
212+- Omit process steps
213+- Leave output format undefined
214+- Skip quality guidance
215+- Ignore error cases
216+
217+## Creating Agents
218+
219+### Method 1: AI-Assisted Generation
220+
221+Use this prompt pattern (extracted from Claude Code):
222+
223+```
224+Create an agent configuration based on this request: "[YOUR DESCRIPTION]"
225+
226+Requirements:
227+1. Extract core intent and responsibilities
228+2. Design expert persona for the domain
229+3. Create comprehensive system prompt with:
230+ - Clear behavioral boundaries
231+ - Specific methodologies
232+ - Edge case handling
233+ - Output format
234+4. Create identifier (lowercase, hyphens, 3-50 chars)
235+5. Write description with triggering conditions
236+6. Include 2-3 <example> blocks showing when to use
237+
238+Return JSON with:
239+{
240+ "identifier": "agent-name",
241+ "whenToUse": "Use this agent when... Examples: <example>...</example>",
242+ "systemPrompt": "You are..."
243+}
244+```
245+
246+Then convert to agent file format with frontmatter.
247+
248+See `examples/agent-creation-prompt.md` for complete template.
249+
250+### Method 2: Manual Creation
251+
252+1. Choose agent identifier (3-50 chars, lowercase, hyphens)
253+2. Write description with examples
254+3. Select model (usually `inherit`)
255+4. Choose color for visual identification
256+5. Define tools (if restricting access)
257+6. Write system prompt with structure above
258+7. Save as `agents/agent-name.md`
259+
260+## Validation Rules
261+
262+### Identifier Validation
263+
264+```
265+✅ Valid: code-reviewer, test-gen, api-analyzer-v2
266+❌ Invalid: ag (too short), -start (starts with hyphen), my_agent (underscore)
267+```
268+
269+**Rules:**
270+- 3-50 characters
271+- Lowercase letters, numbers, hyphens only
272+- Must start and end with alphanumeric
273+- No underscores, spaces, or special characters
274+
275+### Description Validation
276+
277+**Length:** 10-5,000 characters
278+**Must include:** Triggering conditions and examples
279+**Best:** 200-1,000 characters with 2-4 examples
280+
281+### System Prompt Validation
282+
283+**Length:** 20-10,000 characters
284+**Best:** 500-3,000 characters
285+**Structure:** Clear responsibilities, process, output format
286+
287+## Agent Organization
288+
289+### Plugin Agents Directory
290+
291+```
292+plugin-name/
293+└── agents/
294+ ├── analyzer.md
295+ ├── reviewer.md
296+ └── generator.md
297+```
298+
299+All `.md` files in `agents/` are auto-discovered.
300+
301+### Namespacing
302+
303+Agents are namespaced automatically:
304+- Single plugin: `agent-name`
305+- With subdirectories: `plugin:subdir:agent-name`
306+
307+## Testing Agents
308+
309+### Test Triggering
310+
311+Create test scenarios to verify agent triggers correctly:
312+
313+1. Write agent with specific triggering examples
314+2. Use similar phrasing to examples in test
315+3. Check Claude loads the agent
316+4. Verify agent provides expected functionality
317+
318+### Test System Prompt
319+
320+Ensure system prompt is complete:
321+
322+1. Give agent typical task
323+2. Check it follows process steps
324+3. Verify output format is correct
325+4. Test edge cases mentioned in prompt
326+5. Confirm quality standards are met

1+# Agent Creation System Prompt
2+
3+This is the exact system prompt used by Claude Code's agent generation feature, refined through extensive production use.
4+
5+## The Prompt
6+
7+```
8+You are an elite AI agent architect specializing in crafting high-performance agent configurations. Your expertise lies in translating user requirements into precisely-tuned agent specifications that maximize effectiveness and reliability.
9+
10+**Important Context**: You may have access to project-specific instructions from CLAUDE.md files and other context that may include coding standards, project structure, and custom requirements. Consider this context when creating agents to ensure they align with the project's established patterns and practices.
11+
12+When a user describes what they want an agent to do, you will:
13+
14+1. **Extract Core Intent**: Identify the fundamental purpose, key responsibilities, and success criteria for the agent. Look for both explicit requirements and implicit needs. Consider any project-specific context from CLAUDE.md files. For agents that are meant to review code, you should assume that the user is asking to review recently written code and not the whole codebase, unless the user has explicitly instructed you otherwise.
15+
16+2. **Design Expert Persona**: Create a compelling expert identity that embodies deep domain knowledge relevant to the task. The persona should inspire confidence and guide the agent's decision-making approach.
17+
18+3. **Architect Comprehensive Instructions**: Develop a system prompt that:
19+ - Establishes clear behavioral boundaries and operational parameters
20+ - Provides specific methodologies and best practices for task execution
21+ - Anticipates edge cases and provides guidance for handling them
22+ - Incorporates any specific requirements or preferences mentioned by the user
23+ - Defines output format expectations when relevant
24+ - Aligns with project-specific coding standards and patterns from CLAUDE.md
25+
26+4. **Optimize for Performance**: Include:
27+ - Decision-making frameworks appropriate to the domain
28+ - Quality control mechanisms and self-verification steps
29+ - Efficient workflow patterns
30+ - Clear escalation or fallback strategies
31+
32+5. **Create Identifier**: Design a concise, descriptive identifier that:
33+ - Uses lowercase letters, numbers, and hyphens only
34+ - Is typically 2-4 words joined by hyphens
35+ - Clearly indicates the agent's primary function
36+ - Is memorable and easy to type
37+ - Avoids generic terms like "helper" or "assistant"
38+
39+6. **Example agent descriptions**:
40+ - In the 'whenToUse' field of the JSON object, you should include examples of when this agent should be used.
41+ - Examples should be of the form:
42+ <example>
43+ Context: The user is creating a code-review agent that should be called after a logical chunk of code is written.
44+ user: "Please write a function that checks if a number is prime"
45+ assistant: "Here is the relevant function: "
46+ <function call omitted for brevity only for this example>
47+ <commentary>
48+ Since a logical chunk of code was written and the task was completed, now use the code-review agent to review the code.
49+ </commentary>
50+ assistant: "Now let me use the code-reviewer agent to review the code"
51+ </example>
52+ - If the user mentioned or implied that the agent should be used proactively, you should include examples of this.
53+ - NOTE: Ensure that in the examples, you are making the assistant use the Agent tool and not simply respond directly to the task.
54+
55+Your output must be a valid JSON object with exactly these fields:
56+{
57+ "identifier": "A unique, descriptive identifier using lowercase letters, numbers, and hyphens (e.g., 'code-reviewer', 'api-docs-writer', 'test-generator')",
58+ "whenToUse": "A precise, actionable description starting with 'Use this agent when...' that clearly defines the triggering conditions and use cases. Ensure you include examples as described above.",
59+ "systemPrompt": "The complete system prompt that will govern the agent's behavior, written in second person ('You are...', 'You will...') and structured for maximum clarity and effectiveness"
60+}
61+
62+Key principles for your system prompts:
63+- Be specific rather than generic - avoid vague instructions
64+- Include concrete examples when they would clarify behavior
65+- Balance comprehensiveness with clarity - every instruction should add value
66+- Ensure the agent has enough context to handle variations of the core task
67+- Make the agent proactive in seeking clarification when needed
68+- Build in quality assurance and self-correction mechanisms
69+
70+Remember: The agents you create should be autonomous experts capable of handling their designated tasks with minimal additional guidance. Your system prompts are their complete operational manual.
71+```
72+
73+## Usage Pattern
74+
75+Use this prompt to generate agent configurations:
76+
77+```markdown
78+**User input:** "I need an agent that reviews pull requests for code quality issues"
79+
80+**You send to Claude with the system prompt above:**
81+Create an agent configuration based on this request: "I need an agent that reviews pull requests for code quality issues"
82+
83+**Claude returns JSON:**
84+{
85+ "identifier": "pr-quality-reviewer",
86+ "whenToUse": "Use this agent when the user asks to review a pull request, check code quality, or analyze PR changes. Examples:\n\n<example>\nContext: User has created a PR and wants quality review\nuser: \"Can you review PR #123 for code quality?\"\nassistant: \"I'll use the pr-quality-reviewer agent to analyze the PR.\"\n<commentary>\nPR review request triggers the pr-quality-reviewer agent.\n</commentary>\n</example>",
87+ "systemPrompt": "You are an expert code quality reviewer...\n\n**Your Core Responsibilities:**\n1. Analyze code changes for quality issues\n2. Check adherence to best practices\n..."
88+}
89+```
90+
91+## Converting to Agent File
92+
93+Take the JSON output and create the agent markdown file:
94+
95+**agents/pr-quality-reviewer.md:**
96+```markdown
97+---
98+name: pr-quality-reviewer
99+description: Use this agent when the user asks to review a pull request, check code quality, or analyze PR changes. Examples:

120+```
121+
122+## Customization Tips
123+
124+### Adapt the System Prompt
125+
126+The base prompt is excellent but can be enhanced for specific needs:
127+
128+**For security-focused agents:**
129+```
130+Add after "Architect Comprehensive Instructions":
131+- Include OWASP top 10 security considerations
132+- Check for common vulnerabilities (injection, XSS, etc.)
133+- Validate input sanitization
134+```
135+
136+**For test-generation agents:**
137+```
138+Add after "Optimize for Performance":
139+- Follow AAA pattern (Arrange, Act, Assert)
140+- Include edge cases and error scenarios
141+- Ensure test isolation and cleanup
142+```
143+
144+**For documentation agents:**
145+```
146+Add after "Design Expert Persona":
147+- Use clear, concise language
148+- Include code examples
149+- Follow project documentation standards from CLAUDE.md
150+```
151+
152+## Best Practices from Internal Implementation
153+
154+### 1. Consider Project Context
155+
156+The prompt specifically mentions using CLAUDE.md context:
157+- Agent should align with project patterns
158+- Follow project-specific coding standards
159+- Respect established practices
160+
161+### 2. Proactive Agent Design
162+
163+Include examples showing proactive usage:
164+```
165+<example>
166+Context: After writing code, agent should review proactively
167+user: "Please write a function..."
168+assistant: "[Writes function]"
169+<commentary>
170+Code written, now use review agent proactively.
171+</commentary>
172+assistant: "Now let me review this code with the code-reviewer agent"
173+</example>
174+```
175+
176+### 3. Scope Assumptions
177+
178+For code review agents, assume "recently written code" not entire codebase:
179+```
180+For agents that review code, assume recent changes unless explicitly
181+stated otherwise.
182+```
183+
184+### 4. Output Structure
185+
186+Always define clear output format in system prompt:
187+```
188+**Output Format:**
189+Provide results as:
190+1. Summary (2-3 sentences)
191+2. Detailed findings (bullet points)
192+3. Recommendations (action items)
193+```
194+
195+## Integration with Plugin-Dev
196+
197+Use this system prompt when creating agents for your plugins:
198+
199+1. Take user request for agent functionality
200+2. Feed to Claude with this system prompt
201+3. Get JSON output (identifier, whenToUse, systemPrompt)

368+
369+**Avoid > 10,000 words:** Too long, diminishing returns.
370+
371+## Testing System Prompts
372+
373+### Test Completeness
374+
375+Can the agent handle these based on system prompt alone?
376+
377+- [ ] Typical task execution
378+- [ ] Edge cases mentioned
379+- [ ] Error scenarios
380+- [ ] Unclear requirements
381+- [ ] Large/complex inputs
382+- [ ] Empty/missing inputs
383+
384+### Test Clarity
385+
386+Read the system prompt and ask:
387+
388+- Can another developer understand what this agent does?
389+- Are process steps clear and actionable?
390+- Is output format unambiguous?
391+- Are quality standards measurable?
392+
393+### Iterate Based on Results
394+
395+After testing agent:
396+1. Identify where it struggled
397+2. Add missing guidance to system prompt
398+3. Clarify ambiguous instructions
399+4. Add process steps for edge cases
400+5. Re-test
401+
402+## Conclusion
403+
404+Effective system prompts are:
405+- **Specific**: Clear about what and how
406+- **Structured**: Organized with clear sections
407+- **Complete**: Covers normal and edge cases
408+- **Actionable**: Provides concrete steps
409+- **Testable**: Defines measurable standards
410+
411+Use the patterns above as templates, customize for your domain, and iterate based on agent performance.

138+```
139+
140+### Type 2: Proactive Triggering
141+
142+Agent triggers after relevant work without explicit request:
143+
144+```markdown

170+assistant: "I'll use the code-simplifier agent to suggest improvements."
171+</example>
172+```
173+
174+### Type 4: Tool Usage Pattern
175+
176+Agent triggers based on prior tool usage:
177+
178+```markdown
179+<example>
180+Context: User made multiple edits to test files
181+user: "I've updated all the tests"
182+assistant: "Great! Let me verify test quality."

439+## Debugging Triggering Issues
440+
441+### Agent Not Triggering
442+
443+**Check:**
444+1. Examples include relevant keywords from user message
445+2. Context matches actual usage scenarios
446+3. Commentary explains triggering logic clearly
447+4. Assistant shows use of Agent tool in examples
448+
449+**Fix:**
450+Add more examples covering different phrasings.
451+
452+### Agent Triggers Too Often
453+
454+**Check:**
455+1. Examples are too broad or generic
456+2. Triggering conditions overlap with other agents
457+3. Commentary doesn't distinguish when NOT to use
458+
459+**Fix:**
460+Make examples more specific, add negative examples.
461+
462+### Agent Triggers in Wrong Scenarios
463+
464+**Check:**
465+1. Examples don't match actual intended use
466+2. Commentary suggests inappropriate triggering
467+
468+**Fix:**
469+Revise examples to show only correct triggering scenarios.
470+
471+## Best Practices Summary
472+
473+✅ **DO:**
474+- Include 2-4 concrete, specific examples
475+- Show both explicit and proactive triggering
476+- Provide clear context for each example
477+- Explain reasoning in commentary
478+- Vary user message phrasing
479+- Show Claude using Agent tool
480+
481+❌ **DON'T:**
482+- Use generic, vague examples
483+- Omit context or commentary
484+- Show only one type of triggering
485+- Skip the agent invocation step
486+- Make examples too similar
487+- Forget to explain why agent triggers
488+
489+## Conclusion
490+
491+Well-crafted examples are crucial for reliable agent triggering. Invest time in creating diverse, specific examples that clearly demonstrate when and why the agent should be used.

147+
148+## Frontmatter Fields Quick Reference
149+
150+| Field | Purpose | Example |
151+|-------|---------|---------|
152+| `description` | Brief description for /help | `"Review code for issues"` |
153+| `allowed-tools` | Restrict tool access | `Read, Bash(git:*)` |
154+| `model` | Specify model | `sonnet`, `opus`, `haiku` |
155+| `argument-hint` | Document arguments | `[pr-number] [priority]` |
156+| `disable-model-invocation` | Manual-only command | `true` |

186+argument-hint: [file-path]
187+---
188+
189+Generate documentation for @$1
190+```
191+

197+allowed-tools: Bash(git:*)
198+---
199+
200+Current status: !`git status`
201+Recent commits: !`git log --oneline -5`
202+```
203+
204+## Development Workflow
205+
206+1. **Design command:**
207+ - Define purpose and scope
208+ - Determine required arguments
209+ - Identify needed tools
210+
211+2. **Create file:**
212+ - Choose appropriate location
213+ - Create `.md` file with command name
214+ - Write basic prompt
215+
216+3. **Add frontmatter:**
217+ - Start minimal (just description)
218+ - Add fields as needed (allowed-tools, etc.)
219+ - Document arguments with argument-hint
220+
221+4. **Test command:**
222+ - Invoke with `/command-name`
223+ - Verify arguments work
224+ - Check bash execution
225+ - Test file references
226+
227+5. **Refine:**
228+ - Improve prompt clarity
229+ - Handle edge cases
230+ - Add examples in comments
231+ - Document requirements
232+
233+## Best Practices Summary
234+
235+1. **Single responsibility**: One command, one clear purpose
236+2. **Clear descriptions**: Make discoverable in `/help`
237+3. **Document arguments**: Always use argument-hint
238+4. **Minimal tools**: Use most restrictive allowed-tools
239+5. **Test thoroughly**: Verify all features work
240+6. **Add comments**: Explain complex logic
241+7. **Handle errors**: Consider missing arguments/files
242+
243+## Status
244+
245+**Completed enhancements:**
246+- ✓ Plugin command patterns (${CLAUDE_PLUGIN_ROOT}, discovery, organization)
247+- ✓ Integration patterns (agents, skills, hooks coordination)
248+- ✓ Validation patterns (input, file, resource validation, error handling)
249+
250+**Remaining enhancements (in progress):**
251+- Advanced workflows (multi-step command sequences)
252+- Testing strategies (how to test commands effectively)
253+- Documentation patterns (command documentation best practices)
254+- Marketplace considerations (publishing and distribution)
255+
256+## Maintenance
257+
258+To update this skill:
259+1. Keep SKILL.md focused on core fundamentals
260+2. Move detailed specifications to references/
261+3. Add new examples/ for different use cases
262+4. Update frontmatter when new fields added
263+5. Ensure imperative/infinitive form throughout
264+6. Test examples work with current Claude Code
265+
266+## Version History
267+
268+**v0.1.0** (2025-01-15):
269+- Initial release with basic command fundamentals
