Blueprints

A blueprint is a reusable agent pattern. Each blueprint ships:

• A blueprint.yaml spec (metadata + file list + validators)
• Jinja2 templates for the universal harness files (AGENTS.md, SOUL.md, TOOLS.md, MEMORY.md)
• Skill bundles in anthropics/skills format
• Python validator modules
• Memory JSON Schemas
• An eval question set

v0.1 ships three:

Blueprint	Doc
rag-agent	RAG agent
support-agent	Support agent
workflow-agent	Workflow agent

v0.2 will add sales-agent, browser-agent, finance-agent.

Pick a blueprint

harness blueprint list           # see installed
harness blueprint show rag-agent # full spec
harness init --blueprint rag-agent

Recommendation heuristic

If you don't pass --blueprint, harness recommends:

• rag-agent when the repo has vector-store deps (langchain, qdrant, chroma, pinecone, weaviate, faiss) or "rag" / "docs" in the project name
• support-agent when the repo is a Django/Rails/Zulip/Discourse web-app or has "support" / "help" in the name
• workflow-agent otherwise (the generic default)

Explicit --blueprint always wins.
