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

Without annotations, the description must cover behavioral traits. It discloses a rate limit constraint, which is valuable. However, it does not mention other important aspects such as authorization requirements, side effects (e.g., ad visibility during update), or whether changes are reversible.

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 extremely concise (two sentences), front-loads the core function, and adds a specific constraint without unnecessary words. Every sentence serves a purpose.

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?

Given the complexity (12 required parameters, nested object, no output schema), the description is insufficient. It does not explain the purpose of key parameters, the meaning of 'relist,' or what the response contains. The rate limit note is helpful but does not compensate for the overall lack of detail.

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 description coverage is 0%, so the description should compensate. It provides no information about the 12 parameters (e.g., price, premium, actionType enums). The description fails to add any meaning beyond the raw schema, leaving the agent without guidance on how to set parameters correctly.

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 tool's purpose: 'Update or relist a P2P advertisement.' This specifies both the verb (update/relist) and the resource (advertisement), and implicitly distinguishes it from sibling tools like 'postAd' (create) and 'removeAd' (delete).

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 provides a rate limit note (max 10 modifications per 5 minutes), but lacks explicit guidance on when to use this tool versus alternatives such as 'postAd' or 'removeAd'. It does not state prerequisites or when not to use it, leaving ambiguity for the agent.

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