What it does

Create new agents for the code-forge application. Agents are stored as .md files in the <cwd>/.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.

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 <cwd>/.forge/agents directory, where <cwd> is the current working directory of your code-forge project.

  • Directory: <cwd>/.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

---
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}}</{{event.name}}>
  <system_date>{{current_date}}</system_date>
