SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Agent development for Claude Code plugins enables teams to design and deploy autonomous agents that operate within a plugin, coordinating tasks across tools and data while aligning with project conventions.

Core Features & Use Cases

  • Structured frontmatter design for agents (name, description, model, color, tools)
  • Comprehensive system prompts including core responsibilities, analysis process, quality standards, and output formats
  • Triggering examples that demonstrate explicit, proactive, and edge-case activations
  • Validation and testing hooks to ensure safety and correctness
  • Support for optional resources (scripts/, references/, assets/)

Quick Start

Create a new agent by providing frontmatter, a complete system prompt, and validation hooks, then run the project’s validation suite.

FAQPage Schema
How do I build autonomous agents for Claude Code plugins?

Building autonomous Claude Code plugin agents involves defining structured frontmatter for name, description, model, color, and tools. You then create a robust system prompt with core responsibilities, analysis processes, and output formats, supplemented by triggering examples and validation hooks.

What is structured frontmatter for Claude Code agents?

Structured frontmatter for Claude Code agents is a metadata header that defines the agent's name, description, model, color, and allowed tools. This configuration enables the agent to operate autonomously within a plugin and coordinate tasks across data and tools.

How do I create system prompts for autonomous code review agents?

Creating system prompts for autonomous code review agents requires detailing core responsibilities, the analysis process, quality standards, and exact output formats. You must also include triggering examples that demonstrate explicit, proactive, and edge-case activations for the agent.

Can I use validation scripts to test autonomous agent workflows?

Yes, you can use validation scripts to test autonomous agent workflows. Agent development for Claude Code plugins supports validation and testing hooks to ensure safety and correctness, allowing you to run a project's validation suite against the generated agent behavior.

Does agent development for Claude Code support optional resources like scripts and references?

Yes, agent development for Claude Code supports optional resources including scripts, references, and assets directories. These resources allow you to bundle supplementary execution scripts and documentation alongside the agent's system prompt and frontmatter configuration.

What are the limitations when triggering autonomous agents in Claude Code?

Limitations when triggering autonomous agents in Claude Code involve ensuring safety considerations are strictly enforced. You must provide explicit, proactive, and edge-case triggering examples to prevent unintended activations, relying on validation hooks to constrain autonomous tool usage.
