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

The description adds the ownership constraint ('your listings') and the deactivate action, which goes slightly beyond the annotations' read/write hints. It does not explain effects like whether deactivation is reversible or what happens to the listing, so it's minimal.

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 a single, compact sentence with no wasted words, but it is under-specified for a tool with six parameters. It earns its place but sacrifices completeness.

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 tool's moderate complexity (six parameters, no output schema), the description is too sparse to guide an agent on field semantics, allowed values, or the effect of the active flag. It provides only the top-level action, leaving significant gaps.

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% because the description does not mention any of the six parameters. It leaves the user to infer meanings for fields like priceGas, category, and active from their names and schema constraints.

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 a specific verb+resource: update or deactivate a listing. The '[Sell]' prefix and 'your listings' distinguish it from purchase and other listing tools, making it identifiable among siblings.

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 context that this tool is for sellers to manage their own listings, but does not mention alternatives or when not to use it. It offers no explicit exclusions or comparisons to sibling tools like list_service.

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