AgentBuilder Skill

This guide is a living record. It is not part of the Standard Agent Specification — it exists to help humans and coding agents use the spec to build effective agents. It is updated regularly and not bound to any spec version.

Commands like pnpm exec agents … are placeholders. Use whichever package manager (npm, pnpm, yarn, bun) the project actually uses.

For deeper reference material that this skill links to, see:

• agents/agents/AGENTS.md — agent definition reference (created by agents scaffold)
• agents/prompts/AGENTS.md — prompt and tool config reference
• agents/tools/AGENTS.md — tool-writing patterns and ThreadState examples
• agents/models/AGENTS.md — recommended model list (authoritative)
• agents/hooks/AGENTS.md — hook reference
• Canonical TypeScript types (full signatures): read node_modules/@standardagents/spec/dist/ in your project, or browse packages/spec/src/ on GitHub at https://github.com/standardagents/agentbuilder
• Specification: https://standardagentspec.org/llms.txt
• Builder docs: https://docs.standardagentbuilder.com/llms.txt

If the agents/*/AGENTS.md files don't exist in your project yet, run pnpm exec agents scaffold to create them.
