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

No annotations are provided, so the description carries the full burden. It mentions the underlying Trading API and required OAuth token but lacks details on side effects, whether the original listing ID is reused, rate limits, or what happens on success (e.g., returns new item ID).

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 concise and front-loaded: two short sentences plus a required auth line. Every sentence adds value with no unnecessary text.

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?

The description covers basic purpose and required auth but does not explain the return value or output format. Given no output schema, this is a gap. However, it does state the tool is for ended fixed-price listings, which is key context.

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% and both parameters have descriptions. The description adds minimal new information beyond the schema, only restating that modifications are optional Trading API fields. Baseline 3 is 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?

The description clearly states the verb 'Relist' and the resource 'ended fixed-price listing', and mentions optional modifications. It distinguishes from sibling tools like 'revise_listing' (for active listings) and 'create_listing' (for new listings).

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 implicitly indicates usage for relisting ended listings but does not explicitly state when to use it versus alternatives, nor does it provide when-not-to-use guidance. The required OAuth token is mentioned, which is useful.

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