create_share_link

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

No annotations are provided, so the description carries full responsibility for disclosing behavior. It only states the action without explaining effects of parameters, prerequisites, return value, or potential side effects. This is a significant gap for a creation tool.

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 description is a single, front-loaded sentence with no wasted words. It effectively communicates the core purpose without redundancy.

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?

Given no output schema and minimal annotations, the description is incomplete. It does not mention what the tool returns (presumably the share link URL), any prerequisites like file existence, or how optional parameters affect the created link. An agent would need to infer these details.

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?

The schema covers all four parameters with descriptions, so baseline is 3. The description adds minimal semantic value by hinting at WeTransfer-style controls, but does not elaborate on how password, max_downloads, or expires_in_days interact.

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 clearly states the verb 'Create' with the resource 'a share link for a file'. The parenthetical 'WeTransfer-style' adds context that this is a shareable link with customizable options like password, expiry, and download limits, distinguishing it from related tools like get_file_download_url and revoke_share_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?

The description implies usage via 'WeTransfer-style' (sharing files with controlled access) but does not explicitly state when to choose this tool over alternatives like get_file_download_url. No exclusions or when-not-to-use guidance is provided.

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