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

Beyond the annotations (readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=false), the description discloses the 24-hour link lifetime, 30-day upload retention, that only Nikita can open the files, the 20-file / 20 GB cap, and critically that "making the link sends nothing" — i.e., the call itself has no side effect. It does not address the non-idempotent nature (each call yields a new link), which is the one annotation gap left.

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 purpose and limits are front-loaded, and each sentence carries operational value (what it does, when to use it, how to hand off the link, lifetime, privacy, retention, no side effect). It runs a bit long as a single dense paragraph and could be broken up, but there is little wasted wording.

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 link-generation tool with no output schema, the description covers what is produced (a private upload page), what to do with it (give it to the user), the lifetime, capacity limits, who can access the files, and retention. An agent has everything needed to call it and explain the result correctly.

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%, so every parameter (name, email, company, about) is already documented in the schema, and the baseline of 3 applies. The description adds no further meaning about the parameters, though it does establish that Nikita is the recipient, which implicitly motivates the contact fields.

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 first sentence states a concrete verb and artifact: it returns a private web page where the user uploads files, for a named recipient (Nikita at VIDEO DEPT). It also scopes the accepted content types (footage, photos, logos, references, documents), which clearly separates it from sibling link tools like get_booking_link and get_deposit_link.

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?

"Use it when the user wants to send files that aren't online" gives an explicit trigger, and "Give the user the link; they open it and choose the files themselves" tells the agent how to follow through. There is no explicit when-not or named alternative, so it falls short of a 5.

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