Two tools with critical definition gaps. mind_observe has a reasonable description (89 chars) and complete schema with 4 typed parameters, but lacks parameter descriptions entirely. tools/call is a generic RPC proxy with minimal description (67 chars) and dangerously underspecified input (name and arguments as free-form strings with no constraints, enums, or validation guidance). Neither tool follows verb_noun naming conventions. No output schemas documented. No error handling guidance. No tool annotations. This server fails basic definition quality standards.

• Rename mind_observe to persist_memory and tools/call to invoke_brain_tool. Use verb_noun convention so LLM infers intent from the name alone.
• Add parameter descriptions to mind_observe: mode (enum: 'whisper', 'text', etc.), content (string, max 10000 chars), tags (array of strings, 1-20 tags), context (JSON object with source, chat_id, message_id, received_at fields).
• Replace tools/call with explicit tool wrappers (e.g., get_brain_status, search_brain_memory, update_brain_config) that declare valid names and required arguments. If a generic proxy is necessary, document the full list of valid brain tool names and their argument schemas.
• Document output schemas: persist_memory returns {memory_id: string, created_at: ISO8601, tags: string[]}. invoke_brain_tool returns {result: object, status: 'success'|'error', error_message?: string}.
• Add error handling: 'If persist_memory fails with quota_exceeded, wait 60s and retry. If invoke_brain_tool returns unknown_tool, call list_brain_tools() to discover available tools.'
