Single tool server with moderate definition gaps. Tool has description and named parameters with types, but lacks comprehensive schema documentation, error handling guidance, and important contextual details. No tool annotations (readOnlyHint/destructiveHint/idempotentHint). Output schema is not documented. The generate-image tool performs a WRITE operation (sends to Discord, calls external APIs) but lacks confirmation pattern, error recovery guidance, and proper result documentation. Description is 196 chars (within baseline 34-392 range) but generic. Parameters have descriptions but lack format/constraint details (e.g., what format is targetId? what constitutes a valid Discord ID?). No pagination, no async-result polling guidance despite function being fire-and-forget.
Generates an image using AI based on the given prompt and sends it through Discord to a specific recipient (an User or a Channel). Make sure to be very specific and detailed in the prompt. Only use this tool when the user asks for an image.
Tool performs WRITE operation (sends to Discord, generates and uploads images) but lacks confirmation/dry-run pattern. No error recovery guidance or retry logic exposed to agent.
Output schema not documented in code. Handler returns generic text response {content: [{type: 'text', text: '...'}]} without documenting structure, field names, or success/failure indicators. Agent cannot parse results reliably.
Async fire-and-forget pattern (returns immediately, processes image generation in background via Promise) not documented. Agent cannot know when result is available, cannot poll for status, cannot link conversation to generated image.
Parameter 'targetId' is underspecified. Description says 'Discord recipient Id' but does not clarify: is this a numeric Discord ID? A mention? A username? What format? No validation hints. LLM likely to pass invalid values.

No error classification or recovery guidance. If Gemini API fails, image upload fails, or Discord send fails, agent receives only 'Error generating image' with no actionable next step. Does not tell agent to retry, escalate, or ask user for clarification.
Tool accepts 'userName' as input parameter but does not validate or sanitize it. This field is forwarded to external Discord API, potential for injection or unexpected behavior if malicious/unusual characters included.
No tool annotations present (readOnlyHint, destructiveHint, idempotentHint). Tool modifies state (creates image, uploads to external service, sends Discord message) but LLM has no machine-readable signal that this is irreversible.
'prompt' parameter lacks format/length constraints. No guidance on specificity requirements despite description saying 'Make sure to be very specific and detailed'. LLM may pass overly short or vague prompts.
