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

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/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

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
