Single tool (generate_image) with complete schema and basic descriptions. Tool name follows verb_noun pattern appropriately. Input schema is well-defined with proper JSON Schema including types, enums, min/max constraints. However, descriptions lack sufficient LLM-optimization depth, they are factual but don't explain WHEN to use the tool, prerequisites, or dependencies. Output format is not documented, and the response_format parameter description is overly verbose and confusing. Missing error handling guidance and recovery paths for common failure modes (API outage, rate limits, invalid prompts). Resource mechanism exists but tool integration is shallow.

• Expand tool description to 150-200 characters. Add context: 'Generates images from text prompts using OhMyGPT Flux 1.1 Pro Ultra. Use for creating custom artwork, illustrations, or visual concepts. Supports image-to-image refinement via image_prompt parameter. Returns a URL to the generated image. Each generation consumes API credits.'
• Document the output schema explicitly. Add a note to the tool description or create a separate outputSchema field: 'Returns {url: string, generation_id: string, created_at: ISO8601, dimensions: {width, height}, model: string}'
• Clarify prompt parameter: 'Text description of the desired image (2-1000 characters). Be specific about style, medium, subject, and composition. Avoid ambiguous or offensive content. Examples: "watercolor painting of a sunset over mountains", "photorealistic portrait of a woman with red hair"'
• Document image_prompt dependency: 'URL to a reference image. If provided, image_prompt_strength controls how much the output should resemble this image (0 = ignore reference, 1 = match closely). If omitted, image_prompt_strength is ignored.'
• Remove or justify response_format parameter. If output is always a Markdown image string, hardcode it server-side and remove the parameter. If truly configurable, expand enum to include other formats (json, raw_url, html).
• Add error handling guidance: 'Returns 400 Bad Request if prompt violates content policy (too graphic, hate speech). Returns 429 Too Many Requests if rate limit exceeded, wait 60 seconds and retry. Returns 500 if service is down, retry after 30 seconds. If generation times out after 5 minutes, cancel and retry with a simpler prompt.'
