create_marketplace_listing

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

No annotations provided, so the description must fully disclose behavioral traits. It only says 'Create a new marketplace listing' without mentioning side effects, permissions, or constraints (e.g., whether duplicate listings are allowed). This is insufficient for a creation tool.

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, but it lacks structure and fails to include necessary details. While brevity is appreciated, the tool's complexity (11 parameters, no annotations) warrants more information.

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 complexity, no output schema, no annotations, and 0% schema description coverage, the description is entirely inadequate. It does not explain return values, error conditions, or operational context, making it nearly useless for an AI agent.

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%, and the description provides no additional meaning for any of the 11 parameters. Although some parameters have enums, the description adds no context about how parameters like 'release_id', 'condition', or 'price' should be used or validated.

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 'Create' and resource 'marketplace listing', indicating the tool's purpose. However, it does not distinguish from sibling tools like 'update_marketplace_listing' or 'delete_marketplace_listing', so it lacks differentiation.

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 on when to use this tool versus alternatives. Given the existence of sibling tools like 'update_marketplace_listing' and 'delete_marketplace_listing', the description should clarify context, such as prerequisites or the workflow step where creation is appropriate.

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