Two tools with minimal but present descriptions and empty input schemas. check_silas_messages has a detailed description (180 chars) explaining context and behavior; send_to_silas similarly well-described (165 chars). However, both tools lack input parameter descriptions. check_silas_messages accepts no parameters (empty object), which is acceptable. send_to_silas accepts a 'content' parameter with a type but no description visible in the schema definition shown. No output schemas documented. No error handling guidance. No tool annotations (readOnlyHint/destructiveHint). Naming is clear and verb-based (check_, send_), following pattern:tool conventions. Overall structure is minimal but functional for a simple coordination bridge.

• Add explicit output schema for check_silas_messages: {content: string, timestamp: string, is_empty: boolean}. Document that empty-inbox returns is_empty=true with empty content.
• Add description to send_to_silas 'content' parameter: 'The message body to send to Silas (plain text, max 10000 chars). Will be timestamped server-side.'
• Add error handling guidance: 'If the message cannot be posted, the tool returns an error with a retry hint. If Silas is unreachable, the error indicates whether to queue the message or notify the user.'
• Add tool annotations: readOnlyHint=true for check_silas_messages; destructiveHint=true for send_to_silas (modifies shared state).
• Document the 'empty-inbox' signal explicitly in check_silas_messages description: 'Returns {content: "", timestamp: ""} when no message is waiting, allowing the agent to distinguish between an empty inbox and a message containing only whitespace.'
