name: Build-Assistant description: Build Claude Code framework components (agents, slash commands, skills, plugins) following standardized templates. Use when creating new agents, commands, skills, or plugins for the multiagent framework. allowed-tools: Read, Write, Bash

Build-Assistant

This skill provides templates, validation scripts, and documentation for building Claude Code framework components following the multiagent framework standards.

Instructions

When Creating a New Agent

1. Read the agent template: templates/agents/agent.md.template
2. Read the agent example: templates/agents/agent-example.md
3. Read documentation: docs/claude-code-agents.md (if available)
4. Create agent file with:
   • Proper frontmatter (name, description, tools, model, color)
   • Clear process steps
   • Key rules and output format
5. Validate using: scripts/validate-agent.sh <agent-file>

When Creating a Slash Command

1. Read the command template: templates/commands/command.md.template
2. Read the command example: templates/commands/command-example.md
3. Read documentation: docs/01-claude-code-slash-commands.md
4. Create command file with:
   • Frontmatter (description, argument-hint, allowed-tools)
   • Task invocation with proper subagent_type
   • Success criteria and notes
5. Validate using: scripts/validate-command.sh <command-file>

When Creating a Skill

1. Read the skill template: templates/skills/SKILL.md.template
2. Read the skill example: templates/skills/skill-example/SKILL.md
3. Read documentation: docs/02-claude-code-skills.md
4. Read decision guide: docs/04-skills-vs-commands.md
5. Create SKILL.md with:
   • Frontmatter with "Use when" trigger context
   • Step-by-step instructions
   • Concrete examples
   • Requirements
6. Validate using: scripts/validate-skill.sh <skill-directory>

When Creating a Plugin

1. Read the plugin template: templates/plugins/plugin.json.template
2. Read the plugin example: templates/plugins/example-plugin/
3. Read documentation: docs/03-claude-code-plugins.md
4. Create plugin structure with:
   • .claude-plugin/plugin.json manifest
   • README.md with components list
   • commands/, skills/, agents/ as needed
5. Validate using: scripts/validate-plugin.sh <plugin-directory>

Choosing Between Skills and Commands

Consult docs/04-skills-vs-commands.md to decide:

• Use Skill when: Claude should discover it automatically, complex capability, multiple supporting files
• Use Command when: User explicitly triggers it, simple orchestration, workflow shortcut

Available Resources

Templates

Agents:

• templates/agents/agent.md.template - Standard agent template with frontmatter
• templates/agents/agent-example.md - Complete working example

Commands:

• templates/commands/command.md.template - Standard slash command template
• templates/commands/command-example.md - Complete working example

Skills:

• templates/skills/SKILL.md.template - Standard skill template
• templates/skills/skill-example/SKILL.md - Git commit helper example
• templates/skills/README.md - Skills template documentation

Plugins:

• templates/plugins/plugin.json.template - Plugin manifest template
• templates/plugins/example-plugin/ - Complete plugin example with commands and skills

Validation Scripts

• scripts/validate-agent.sh - Validates agent frontmatter and structure
• scripts/validate-command.sh - Validates command frontmatter and structure
• scripts/validate-skill.sh - Validates SKILL.md frontmatter and "Use when" context
• scripts/validate-plugin.sh - Validates plugin manifest and structure
• scripts/test-build-system.sh - Comprehensive build system test suite

Documentation

• docs/01-claude-code-slash-commands.md - Slash command reference
• docs/02-claude-code-skills.md - Skills reference with frontmatter fields
• docs/03-claude-code-plugins.md - Plugin architecture and structure
• docs/04-skills-vs-commands.md - Decision guide for choosing component type

Requirements

• Templates must exist in templates/ directory
• Validation scripts must be executable
• Documentation files should be available in docs/
• Follow Claude Code standards for frontmatter
• Include "Use when" context in skill descriptions

Best Practices

1. Always validate - Run validation scripts after creation
2. Follow templates - Use provided templates as starting point
3. Read examples - Study working examples before creating new components
4. Check documentation - Consult docs for standards and patterns
5. Test thoroughly - Use test-build-system.sh for comprehensive testing
