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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds nothing beyond the path: no note on whether the returned URL is time-limited, requires authority to the resource, or triggers generation on demand — all material for a link-minting endpoint.

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 opening sentence is duplicated exactly, wasting the most valuable position in the description. The remaining sentence is an operational pointer, so no informational content is front-loaded.

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?

No output schema exists, so the description should describe the return value (a URL string plus any expiration), but it does not. Combined with zero parameter documentation and a nested-object schema, an agent has too little to invoke this confidently beyond guessing from the path.

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 two required nested params (id, noticeId) are only surfaced through path templating that the name already implies. The description does not clarify that 'id' is the contract ID versus the notice ID, nor any format constraints, despite the schema carrying maxLength bounds only.

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 is the URL path repeated twice verbatim, which only implicitly conveys the action (fetch a PDF URL for a contract notice). It does not explain what a 'pdf-url' contains (signed link, expiry, format) or differentiate this from the sibling get_contracts_by_id_notices_ea65abd7caf52b9727785d1d, which lists notices instead.

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 when-to-use or when-not-to-use guidance is given. The only actionable pointer is that describe_operation provides native request schemas, which is a generic redirect rather than a usage condition, and no alternative tool is named.

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