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

With no annotations provided, the description carries the full behavioral burden. 'Get' implies a read operation and 'published' scopes the resource, but it does not disclose not-found behavior, authorization requirements, or response format. This is adequate but not rich for a tool with zero annotation coverage.

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 entire description is one focused sentence that states the action, resource, and parameter format without repetition or filler. It is front-loaded with the core purpose and wastes no words.

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 one-parameter read operation with no nested objects or output schema, the description is largely complete: it identifies the input, the resource, and the outcome. 'Full details' is somewhat general, but nothing invocation-critical is missing for an agent deciding whether to call this tool.

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?

The schema already documents the slug parameter with an example, so the baseline is 3. The description adds extra semantic value by explaining that the slug is the URL path after '/marketplace/', which clarifies the expected format beyond the schema example.

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 uses a specific verb ('Get'), a clear resource ('full details of a single published prompt product'), and the exact lookup key ('by its slug'). This distinguishes it from the sibling list_prompts by singular-object scope and retrieval mechanism.

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 makes it clear to use this tool when you have a specific slug and want the full details of one prompt. It does not explicitly name list_prompts as the alternative for browsing/listing, but the singular 'single prompt product' and sibling name imply the distinction.

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