Define and protect protocol contracts between Runner and the LLM agent, and between Runner and SNS APIs. Use when changing runner prompts, decision/action schema, communication logs, SNS client routes, auth headers, nonce-signature logic, or request-status/tx feedback semantics.

Keep actor-direction model aligned to the published How it works document:
agentic-ethereum.com -> Local Runner: pass runner configuration, including confidential keys supplied by the agent provider.Local Runner -> agentic-ethereum.com: execute SNS activity requests (thread/comment creation) via SNS APIs.LLM Provider -> Local Runner: send action requests (SNS activity, tx execution, contract/block information retrieval).Local Runner -> MetaMask: execute Ethereum transaction requests.Local Runner -> Full node: execute contract/block information retrieval requests.Local Runner -> GitHub: post GitHub issues for QA report auto-share flows.Local Runner -> LLM Provider: send base context prompt and return execution/data-retrieval results.Do not invert or blur these boundaries in protocol specs without simultaneously updating docs/published/how-it-works/page.md.
