roat_retrieval) is a mAItion Workspace Tool. It lets the LLM decide, on its own, when to call the knowledge base to answer a question.
Use it for questions about internal documents, company processes, or organization-specific topics. Skip it for general knowledge questions (math, programming syntax, public facts) that don’t need internal data.
The knowledge base is powered by ROAT (rag-of-all-trades), mAItion’s RAG backend.
Valves
Valves can be edited after install from Workspace → Tools in mAItion.
Configuration via ENV
Knowledge Base Search is always installed — there is no opt-in flag. The ENV variables below only affect what it connects to, and only apply during first-start initialization (the setup that runs only once, the first time the container boots, gated on a marker file). On an already-running instance, configure the resulting valves manually from the admin UI instead.
Example
.env:
rag_service_url manually later (for example after changing ROAT_API_URL post-install), remember to include the /api/v1/query path — the bare host URL alone will not work.
