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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is partly covered. The description adds genuinely new behavioral context beyond that: the link is public ("Anyone with the link can download that file") and should only be shared with the user, which is a meaningful security disclosure the annotations do not convey.

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?

Two short sentences with no waste; the core purpose (a download link to give the user) is front-loaded, followed by the sharing caution. Tightly written, though it could more explicitly name the sibling alternatives.

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 read-only, two-parameter tool with full schema coverage, no output schema, and annotations covering the safety profile, the description is nearly complete. It states the produced artifact and the key sharing constraint, omitting only edge cases or failure behavior.

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 both parameters (file_id and source) are already documented in the schema. The description adds no format or syntax detail for either parameter, so the baseline 3 applies – the schema does the heavy lifting.

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 outcome: a direct download link on Mizito's CDN for an attached file, which tells an agent what it produces. It is clear enough to distinguish the general purpose, but it never explicitly contrasts with siblings like mizito_read_file or mizito_view_image, leaving the agent to infer that this returns a link rather than file content.

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?

"to give to the user" implies the use context (surfacing a link to a user), and the sharing caveat constrains behavior. However there is no explicit statement of when to use this versus alternatives, nor any prerequisite or exclusion, so usage is only implied.

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