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

Annotations indicate this is not read-only or destructive, which the description supports by stating 'upload'. The description adds the prerequisite of a link request, but does not disclose error handling, file size limits, or how the local file path is handled beyond what the schema provides.

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 sentence that efficiently conveys the action and key constraint (pre-requested link). It is front-loaded and concise, though it could benefit from additional details for completeness.

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 the absence of output schema and the presence of a sibling upload tool, the description lacks important context such as what the tool returns, whether the upload is synchronous, file size limits, and when to use an alternative tool. This leaves gaps for an AI agent.

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?

All parameters have schema descriptions (100% coverage), so baseline is 3. The description adds minimal extra meaning beyond the schema, only clarifying that the filebin URL must be requested in advance.

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 (upload) and resource (EduBase temporary file storage), and mentions the prerequisite of a pre-obtained filebin URL. However, it does not differentiate from the sibling tool 'edubase_post_filebin_upload', which may have a similar purpose.

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 that a filebin URL must be obtained in advance, but it does not explicitly state when to use this tool versus alternatives, nor does it mention any prerequisites or when not to use it.

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