edubase_post_filebin_upload

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

Beyond the annotations, the description discloses what the tool returns (identifier, upload link, expiration, maximum file size), the access restriction ('Only the uploading user can use the file'), and the link-reuse behavior governed by force. These are meaningful behavioral details that annotations alone 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?

The description is front-loaded with purpose and return values, then moves directly into the upload workflow and field references. Every sentence adds operational value without repetition or fluff.

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?

With an output schema, full parameter documentation, and annotations, the description still supplies the missing procedural context: the upload sequence, the identifier format, the file usages, and the force behavior. Nothing an agent needs in order to invoke and chain this tool correctly is absent.

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 coverage is 100%, so both parameters are already documented in the input schema, giving a baseline of 3. The description adds value by explaining the force parameter's effect on link reuse, though it does not elaborate on the type enum beyond the schema.

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 verb and resource: 'Generate an upload link for the temporary file storage (filebin)'. It also distinguishes the tool from the sibling edubase_filebin by explaining the two-step workflow, so an agent can identify its role without opening the schema.

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?

It gives explicit usage: upload with edubase_filebin and then reference the returned filebin identifier in specific fields such as question images, attachments, audio, branding, and certificates. It also clarifies the force behavior, stating a previous valid link is returned unless force is set.

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