The server defines 4 tools with explicit schemas and descriptions visible in src/index.ts. Tool names follow verb_noun convention (eliza_chat, eliza_reset, eliza_get_initial, eliza_get_final). Descriptions are present but generic (avg ~100 chars, baseline is 194). Input schemas are present with proper JSON Schema structure. However, parameter descriptions are missing, the 'message' parameter in eliza_chat has a description, but eliza_reset, eliza_get_initial, and eliza_get_final have empty properties with no constraints documented. Output schema is undocumented, responses are returned as text/JSON strings with no formal schema declaration. Error handling exists (try-catch with error messages) but lacks recovery guidance. No parameter validation constraints (enums, ranges, patterns). Tool composition is reasonable (each does one thing) but overall the definitions lack the rigor expected of production tools.

• Add detailed descriptions for tools with no parameters. Example for eliza_reset: 'Reset the ELIZA conversation state, clearing all prior message history. Use this before starting a new conversation to ensure ELIZA has no memory of previous exchanges. Returns a confirmation message.'
• Document the output schema for each tool. Declare what fields are returned, their types, and whether they are always present. Example: eliza_chat returns {response: string, quit: boolean} where response is ELIZA's text reply and quit indicates whether the conversation should end.
• Add validation constraints to the 'message' parameter. Specify a reasonable maximum length (e.g. 1000 chars) and document in the parameter description: 'The message to send to ELIZA (1-1000 characters, required).'
• Enhance error messages with recovery guidance. Change 'Error: Message is required' to 'Message is required, please provide a non-empty string in the message parameter.' Change 'Unknown tool: {name}' to include a list of valid tools.
• Add tool annotations for safety: mark eliza_chat and eliza_get_initial/final with readOnlyHint=true; mark eliza_reset with destructiveHint=true to signal state modification.
• Consider adding a 'mode' or 'style' parameter to eliza_chat to allow the agent to control verbosity or conversation tone, enabling richer control over ELIZA's behavior.
• Add pagination or rate-limiting context if agents are expected to call eliza_chat repeatedly. Declare a reasonable request rate (e.g. max 10 calls per session) to prevent unbounded loops.
