--- name: create-agent description: Create new agents for the code-forge application. Agents are stored as .md files in the /.forge/agents directory with YAML frontmatter (id, title, description, reasoning, tools, user_prompt) and markdown body containing agent instructions. Use when users need to add new agents, modify existing agents, or understand the agent file structure. --- {{{{raw}}}} # Create Agents Create and manage agents for the code-forge application. Agents are specialized AI assistants with specific capabilities, tools, and behaviors. ## File Location **CRITICAL**: All agent files must be created in the `/.forge/agents` directory, where `` is the current working directory of your code-forge project. - **Directory**: `/.forge/agents` - **File format**: `{agent-id}.md` - **Example**: If your project is at `/home/user/my-project`, agents go in `/home/user/my-project/.forge/agents/` This is the only location where forge will discover and load custom agents. ## Agent File Structure Every agent file must have: 1. **YAML Frontmatter** (required): - `id`: Unique agent identifier - `title`: Agent display name - `description`: Detailed description of what the agent does - `reasoning`: Configuration with `enabled: true/false` - `tools`: List of tools the agent can use - `user_prompt`: Template for user context 2. **Agent Body** (required): - Agent identity and purpose - Core principles - Capabilities - Methodology - Best practices - Limitations and boundaries ### Example Agent File ```markdown --- id: "forge" title: "Perform technical development tasks" description: "Hands-on implementation agent that executes software development tasks..." reasoning: enabled: true tools: - sem_search - sage - fs_search - read - write - undo - remove - patch - shell - fetch - skill - mcp_* user_prompt: |- <{{event.name}}>{{event.value}} {{current_date}} --- You are Forge, an expert software engineering assistant... ## Core Principles: ... ``` ### Complete Sample Agent This sample demonstrates a complete agent structure: ```markdown --- id: "sample-agent" title: "Sample agent for demonstration" description: "A sample agent that demonstrates the complete agent file structure with all required fields and common patterns." reasoning: enabled: true tools: - sem_search - read - write - shell user_prompt: |- <{{event.name}}>{{event.value}} {{current_date}} --- You are Sample Agent, a demonstration agent that shows how to structure agent files. ## Core Principles: 1. **Principle 1**: Description of the first core principle 2. **Principle 2**: Description of the second core principle 3. **Principle 3**: Description of the third core principle ## Capabilities: ### Capability Category 1: - Description of first capability - Description of second capability ### Capability Category 2: - Description of third capability - Description of fourth capability ## Methodology: ### Step 1: First Step Description of the first step in the methodology. ### Step 2: Second Step Description of the second step in the methodology. ### Step 3: Third Step Description of the third step in the methodology. ## Best Practices: - Best practice 1 - Best practice 2 - Best practice 3 ## Limitations and Boundaries: This agent cannot perform certain tasks. When asked to do so, politely explain the limitations and suggest alternative approaches. ``` ## Creating a New Agent ### Step 1: Determine Agent Purpose Identify what the agent should accomplish: - What is the agent's primary function? - What tasks will it perform? - What tools does it need? - What are its limitations? - How does it differ from existing agents? ### Step 2: Choose Agent ID and Title Use descriptive IDs and titles: - ID: Use lowercase with hyphens for multi-word (e.g., `code-reviewer`, `test-automation`) - Title: Use clear, descriptive text (e.g., "Review code quality", "Automate testing") ### Step 3: Write the Agent File Create the file in the `/.forge/agents` directory with the format: `{agent-id}.md` **IMPORTANT**: The file MUST be in `/.forge/agents` where `` is your current working directory. Agents placed anywhere else will not be discovered by forge. #### Frontmatter ```yaml --- id: "your-agent-id" title: "Your Agent Title" description: "Detailed description of what this agent does, its capabilities, and when to use it." reasoning: enabled: true tools: - tool1 - tool2 - tool3 user_prompt: |- <{{event.name}}>{{event.value}} {{current_date}} --- ``` #### Agent Body The body should include: - Agent introduction and identity - Core principles (typically 5-7 principles) -
