SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill streamlines the manual and error-prone process of adding new specialist agent personalities to the Legion system by guiding users through a structured conversation, enforcing schema rules, and updating the agent registry so new agents are discoverable and usable in planning and execution workflows.

Core Features & Use Cases

  • Guided Creation Flow: A three-stage adaptive conversation captures identity, capabilities, personality, hard rules, and task-type tags to produce a complete agent personality file.
  • Schema Validation & Safety: Pre-write checks enforce frontmatter format, name uniqueness, allowed colors, division mapping, body length and heading requirements to prevent invalid or conflicting agent entries.
  • Registry Integration: After successful validation, the Skill writes the agent file and inserts a properly formatted registry row into agent-registry.md under the correct division, updating counts where applicable.
  • Use Case: Add a custom engineering-security auditor agent by describing its specialty and capabilities; the Skill will generate the agent Markdown, validate it, and register it for future /legion:plan recommendations.

Quick Start

Ask the agent creator to generate a new custom agent by describing its specialty, top capabilities, and personality.

FAQPage Schema
How do I create a custom agent personality with schema validation?

To create a custom agent personality, you describe its specialty and capabilities to trigger a guided conversation flow. This process enforces frontmatter validation, name uniqueness, and body length checks to generate a compliant agent file.

What is an agent registry and how does onboarding new agents work?

An agent registry is a directory of available agents used for planning and execution workflows. Onboarding involves capturing agent identity, capabilities, and division mapping, then inserting a formatted registry row to make the agent discoverable.

How do I add a specialist agent to a planning workflow?

You add a specialist agent by defining its task-type tags and division mapping during the creation flow. The system validates the schema, writes the agent file, and updates the registry so the agent is usable in future planning recommendations.

Does custom agent file generation enforce name uniqueness and frontmatter format?

Yes, custom agent file generation enforces name uniqueness and frontmatter format through pre-write safety checks. These schema compliance rules also validate allowed colors, body length, and heading requirements to prevent invalid agent entries.

What are the limitations of using guided conversation flows for agent creation?

The guided conversation flow requires completing a three-stage adaptive capture process for identity, capabilities, personality, and hard rules. Pre-write checks will block file generation if schema validation fails or if the agent name conflicts with existing entries.
