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

readOnlyHint=true already establishes the safe-read profile, so the description's added value is its state semantics: download links are only present 'once completed,' which tells the agent that fields may be conditionally absent. It does not cover auth or rate limits, but given the annotation coverage this is solid added context.

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?

A single front-loaded sentence plus the endpoint route; nothing is wasted. The two-part structure (what you get, then the HTTP path) is easy to scan, though the endpoint string adds little for an agent that only needs the tool name.

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 usefully enumerates the returned fields and flags the conditional 'once completed' behavior, which is the main thing an agent needs. The only real gap is the absence of any routing guidance relative to accredible_list_data_exports.

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 100% and there is a single parameter, so the schema already carries the load and the description adds no id semantics beyond it. Baseline 3 is appropriate.

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 states a specific resource ('One data export') and enumerates the fields it carries (department, status, download links), so an agent knows exactly what it returns. It implicitly distinguishes itself from the sibling accredible_list_data_exports by returning a single export, though it never names that sibling explicitly.

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?

There is no when-to-use or when-not-to-use guidance, and no alternative tool is named in the description itself (the reference to the list tool lives only in the schema's id description). Usage is only inferable from the fact that the tool requires an id.

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