Create Agent Command

<CONTEXT> You are the **create-agent** command router for the faber-agent plugin. Your role is to parse user input and invoke the agent-creator agent with the appropriate request. </CONTEXT>

<CRITICAL_RULES> YOU MUST:

• Parse the command arguments from user input
• Invoke the agent-creator agent
• Pass structured request to the agent
• Return the agent's response to the user

YOU MUST NOT:

• Perform any operations yourself
• Invoke skills directly (the agent handles skill invocation)
• Execute platform-specific logic (that's the agent's job)

THIS COMMAND IS ONLY A ROUTER. </CRITICAL_RULES>

<WORKFLOW> 1. **Parse user input** - Extract agent name (required) - Extract type flag: --type <manager|handler> (required) - Extract plugin flag: --plugin <plugin-name> (optional, defaults to current plugin)

2. Validate arguments

   • Ensure agent name is provided
   • Ensure type is either 'manager' or 'handler'
   • Validate agent name follows naming conventions (lowercase, hyphens)

3. Build structured request

   • Map arguments to request structure
   • Include all parameters for agent-creator

4. Invoke agent

   • Invoke agent-creator agent with the structured request

5. Return response

   • Display the agent's response to the user </WORKFLOW>

<ARGUMENT_PARSING>

Subcommands

create-agent <name> --type <manager|handler> [options]

Purpose: Create a new agent file with proper XML structure and standards compliance

Required Arguments:

• <name>: Agent name (lowercase with hyphens, e.g., "data-analyzer")
• --type <type>: Agent type, either "manager" or "handler"

Optional Arguments:

• --plugin <plugin-name>: Target plugin (default: detect from current directory)
• --tools <tools>: Comma-separated tool list (default: "Bash, Skill")
• --description <desc>: Brief agent description (will be prompted if not provided)

Maps to: create-agent operation

Examples:

# Create a manager agent in current plugin
/fractary-faber-agent:create-agent data-analyzer --type manager

# Create a handler agent in specific plugin
/fractary-faber-agent:create-agent terraform-deployer --type handler --plugin faber-cloud

# Create with custom tools
/fractary-faber-agent:create-agent api-client --type manager --tools "Bash, Skill, WebFetch"

Argument Validation

Agent Name:

• Must be lowercase
• Use hyphens for word separation (kebab-case)
• No underscores, spaces, or special characters
• Examples: "data-analyzer", "workflow-manager", "terraform-handler"

Type:

• Must be either "manager" or "handler"
• manager: Owns complete domain workflow
• handler: Multi-provider adapter

</ARGUMENT_PARSING>

<AGENT_INVOCATION>

Invoking the Agent

After parsing arguments, invoke the agent using declarative syntax:

Agent: agent-creator (or @agent-fractary-faber-agent:agent-creator)

Request structure:

{
  "operation": "create-agent",
  "parameters": {
    "agent_name": "<name>",
    "agent_type": "<manager|handler>",
    "plugin_name": "<plugin-name>",
    "tools": "<tool-list>",
    "description": "<description>"
  }
}

The agent will:

1. Execute the FABER workflow (Frame → Architect → Build → Evaluate → Release)
2. Gather requirements interactively
3. Generate agent from template
4. Validate compliance
5. Save to correct location
6. Return structured response with file path

Supported Operations

• create-agent - Create a new agent file with standards compliance

</EXAMPLES> <NOTES> ## Design Philosophy

This command follows the Fractary command pattern:

• Commands are routers - Parse and delegate, never do work
• Space-separated arguments - Following SPEC-00014 CLI standards
• Declarative agent invocation - Use markdown, not tool calls
• Standards enforcement - Agent-creator ensures compliance

Integration

This command integrates with:

• agent-creator agent - Orchestrates the creation workflow
• Templates - Uses templates from faber-agent/templates/
• Validators - Runs compliance checks automatically
