Create a meme

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

With no annotations provided, the description carries the full burden. It explains text placement order (top-to-bottom), behavior for different caption counts, and rate limits. It does not cover auth requirements or error conditions, but the given details are good for a creation tool.

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?

The description is three sentences long, front-loaded with the primary purpose, and every sentence adds essential information. There is no redundancy or unnecessary detail.

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?

Despite lacking an output schema, the description mentions return values (meme page URL and direct image URL). It includes rate-limit advice and the text placement logic. For a tool with only two simple parameters, this is fairly complete, though error handling is not covered.

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 descriptions for both parameters. The description adds context about top-to-bottom order and matching suggestedCaptionCount, which provides some extra value beyond the schema, but not significantly more.

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?

The description clearly states the verb 'create', the resource 'meme', the platform 'memebo.at', and the action 'captioning a template'. It distinguishes itself from siblings like get_meme_template and search_meme_templates, which are about reading or searching templates.

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?

The description mentions rate-limiting per IP and advises spacing repeated calls, but it does not explicitly state when to use this tool versus alternatives or when not to use it. The context of siblings implies usage, but explicit guidance is missing.

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