create_marketplace_listing

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

The description discloses no behavioral traits. Given that annotations are absent, the description should inform about side effects (e.g., creates a listing visible to others), authentication needs, or rate limits. It provides none, leaving the agent blind to operational impact.

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 sentence with no unnecessary words, but it is under-specified rather than concise. It lacks essential information, making it inadequate for effective tool use. Conciseness without completeness is not valuable.

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 (11 parameters, no annotations, no output schema), the description is severely incomplete. It does not explain the concept of a marketplace listing, the purpose of each parameter, or the return value. The tool is essentially undocumented beyond its name.

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?

With schema description coverage at 0%, the description must compensate by explaining parameters. It does not mention any of the 11 parameters (e.g., release_id, condition, price) or their significance. The agent has no semantic understanding beyond schema types.

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 'Create a new marketplace listing' clearly states the action (create) and the resource (marketplace listing). It distinguishes from siblings like update or delete by the verb 'create'. However, it does not elaborate on what a marketplace listing entails, but the name itself is sufficiently clear for basic purpose.

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 usage guidelines are provided. The description offers no context on when to use this tool versus alternatives (e.g., when to create vs. update a listing), no prerequisites, and no conditions. This is a significant gap for a tool with many sibling operations.

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