agent-builder

Agent-builder lets you define Claude agents by creating YAML frontmatter files that specify agent name, description, scoped tool permissions (like Read or Glob), model selection (e.g., sonnet), and system prompt structure. This ensures agents are configured consistently and ready for deployment.

Structure system prompts with clear role lines, numbered sections, and constraint markers to guide agent behavior effectively. Agent-builder follows a standardized composition approach that ensures your agent responds predictably to its intended use cases.

Write compelling agent descriptions with "Use when" clauses and proactive triggers in your agent definition. Agent-builder guides you through crafting discovery metadata that maximizes when your agent is automatically invoked.

Yes, agent-builder lets you specify exactly which tools your agent can use through declarative tool permissions in the agent's YAML frontmatter, ensuring security and focused behavior for each specialized agent.

Agent-builder provides a 5-phase workflow: Understand your agent's purpose, Acquire requirements, Research best practices, Author the agent configuration, and Validate against schema and trigger coverage. This ensures research-informed and compliant agent creation.

Agent-builder includes frontmatter schema validation as part of its workflow, checking that your agent configuration meets requirements for discovery triggers, tool scoping, and model alignment before deployment.
