Upload to Pshare and get a share link

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

No annotations are provided, so the description carries the full burden. It clearly states the upload side-effect and the nature of the return value, but it does not disclose potential caveats such as file size limits, authentication requirements, or whether an existing share is reused or a new one is created. The UI-equivalence note adds value, but behavioral disclosure remains basic.

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 that immediately states the action and outcome. Every phrase earns its place, and there is zero filler or repetition of schema field names.

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?

The tool has no output schema, so the description's mention of the returned share link is valuable for understanding what to expect. With six parameters well-documented in the schema and a straightforward purpose, the description is complete enough for an agent to use the tool, though it could add edge-case behavior (e.g., handling of inaccessible paths).

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 the description rightfully leaves parameter details to the schema. The only parameter-related hint in the description is 'one or more files/folders', which mirrors the 'paths' array. This adds no meaning beyond the schema, so 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 names a specific verb ('Uploads'), a clear resource ('one or more files/folders from this machine to Pshare'), and a concrete outcome ('returns the same share link a user would get'). It fully distinguishes the tool's purpose even without sibling tools.

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 provides clear usage context by equating the tool's output to the UI 'Share' action, implying when to use it: whenever a user would upload files via the Pshare interface. It does not explicitly mention exclusions or alternatives, but with no sibling tools, this is sufficient.

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