Honcho
7,403 starsHermes Agent memory provider maintained by Plastic Labs (official catalog entry, review-pinned commit): cross-session user modeling — dialectic Q&A, semantic search and persistent conclusions remember who the user is and what they prefer, with an on_session_end hook processing data when sessions close.

Host
The catalog YAML declares it plainly: HONCHO_API_KEY is required and an on_session_end hook is installed — at session close, conversation data goes to Honcho's cloud (Plastic Labs' service) for user modeling; later sessions retrieve those conclusions-about-you via semantic search.
It plugs into Hermes' memory-provider seam and the on_session_end hook — both proprietary interfaces of the Hermes plugin system (declared in the catalog YAML's capabilities). Other hosts have neither the same hook events nor the provider contract.
Risk
One of the most direct data-export plugins in the catalog: your conversations are distilled into a persistent user profile held in a third-party cloud. The profile itself is sensitive (preferences, habits, identity details); a leaked API key lets others read/write it; an injected session can write false or malicious "conclusions" into the long-term profile, shaping every later session.
Install prompt
在 Hermes Agent 的插件目錄中以名稱安裝 honcho，並按官方整合說明（目錄 docs_url 指向 plastic-labs/honcho 倉庫的 hermes-plugin-honcho 目錄 README）設定 HONCHO_API_KEY 環境變數。Paste this to your agent. It deliberately contains no tool subcommands — check the tool's official docs for commands.
