edubase_filebin

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

Annotations already indicate write operation and non-destructive behavior. The description adds the prerequisite of requesting a link in advance but does not disclose file size limits, overwrite behavior, or error handling. No contradiction with annotations.

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?

Single sentence that conveys the core purpose and one key prerequisite. Slightly awkward phrasing ('with a link requested from the API in advance') but overall efficient and front-loaded.

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 description explains input well but lacks any mention of output or return value. Without an output schema, the AI is left guessing what the tool returns. Adequate for a basic upload operation but missing completeness.

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 parameter descriptions already exist. The description adds no significant new meaning beyond the schema, only restating that source can be local file or URL.

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?

Description clearly states 'Upload a local file or a file from a URL to the EduBase temporary file storage', specifying the action and target. It also mentions the prerequisite of having a filebin URL, distinguishing it from other 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?

Description implies that a filebin URL must be obtained beforehand but does not explicitly compare to sibling tools like edubase_post_filebin_upload. No 'when to use' 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.
