analyze_image

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided; description only mentions model and URL requirement. Lacks details on read/write nature, rate limits, error handling, or return format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two efficient sentences with no fluff. Purpose and constraint clearly stated upfront.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for simple image analysis but lacks explanation of output (no output schema). With no annotations and no return info, description is minimally complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with parameter descriptions. The tool description adds little beyond schema (URL must be publicly reachable is already implied by schema's 'public URL'). Baseline 3 appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the action 'Analyze an image via URL' and specifies the model Qwen3.7-Plus. Distinguishes from sibling tools like analyze_video by targeting images.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implied usage for image analysis, but no explicit guidance on when to use this tool vs siblings like 'analyze_video' or 'summarize_video'. Mentions URL requirement but no when-not-to-use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
