tldr

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

The only disclosed behavioral trait is the $0.001 USDC cost via x402. With no annotations, the description carries the full burden for revealing side effects, input requirements, or limitations, but none of that is provided.

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 short and front-loaded, but it is under-specified rather than concise. 'Content & AI tool' adds little value, and the cost note is the only substantive information, so the text does not earn its place.

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?

For an AI content tool with no annotations, no output schema, and vague schema, the description is completely inadequate. It fails to explain the tool's function, input format, output, or relationship to similar tools, making it impossible for an agent to use correctly.

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?

The schema contains only a generic 'params' object with no meaningful field descriptions, and the tool description adds no parameter details. Although schema coverage is nominally 100%, the actual parameter semantics are undocumented, leaving the agent without guidance on what to supply.

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 only says 'Content & AI tool' and mentions cost, but never states what the tool actually does. The name 'tldr' hints at summarization, but the description itself provides no verb or resource, making it nearly tautological and indistinguishable from siblings like summarize.

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?

No guidance is given for when to use this tool versus alternatives. There is no mention of use cases, exclusions, or related tools, so an agent gets no help in choosing between tldr and summarize or other content tools.

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