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

No annotations are supplied, so the description carries the full burden. It does disclose one meaningful behavioral trait — that a download URL to the leaked file is returned — but says nothing about permissions, rate limits, or whether fetching that URL has side effects. Adequate, not rich.

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 two substantive sentences are front-loaded and efficient. However, the trailing '### Responses: **200**' block is boilerplate HTTP noise that adds nothing for an agent and dilutes an otherwise tight definition.

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?

With no output schema, the description should explain the return shape, and it partially does by mentioning the download URL. It omits what other detail fields are returned and any constraints on the ID format, leaving meaningful gaps for a detail-fetch 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?

Schema coverage is 100%, so both the id and search_highlight parameters are already documented in the schema. The description adds no meaning beyond that and never mentions search_highlight. Baseline 3 applies.

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?

States a specific verb and resource ('Get full details of a specific leak by its unique ID') and names a concrete payload element (download URL). It is distinguishable from the search_leaks_by_* siblings, though the boundary with get_document_by_id / get_document_html_by_id is not addressed.

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?

Explicitly tells the agent when to call it: 'Use this after finding a leak ID from search results,' which establishes the prerequisite flow. It gives no exclusion case (e.g., when to prefer the document endpoints), so it falls short of naming alternatives.

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