Validate Listing Text

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

With no annotations, the description carries full responsibility for behavioral disclosure. While 'validate' implies no side effects, the description does not disclose what happens on success or failure (return value, exceptions), rate limits, or authorization needs. It is a minimal statement that leaves much to be inferred.

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, concise sentence with no wasted words. It is front-loaded with the action verb and resource, making it highly scannable and effective.

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 a tool with no annotations and only a minimal description, key context is missing: return format, error handling, and whether any state changes occur. While a validation tool likely doesn't modify data, the description relies heavily on the user's inference. The existence of an output schema mitigates some but not all 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 coverage is 100% with each parameter having a clear description including its max length. The tool description's 'lengths' adds no extra meaning beyond the schema, meeting the baseline. The description neither enriches nor detracts from schema understanding.

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 'Validate' and the resource 'store listing text', with a specific focus on 'lengths before updating'. It distinguishes itself from siblings like update_listing by implying a pre-update check, though it could be more explicit about the validation being non-mutating.

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 phrase 'before updating' gives clear temporal context, implying it should be used prior to update_listing. However, it does not explicitly state when not to use it or mention alternatives. The usage guidance is present but not comprehensive.

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