edubase_post_video_permission

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

Annotations indicate it's a non-idempotent mutation with no destructive hint. However, the description does not disclose behavior on duplicate creation, authorization requirements, or side effects. This leaves ambiguity.

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 directly states the tool's function with no extraneous words. Perfectly concise.

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?

Tool is simple with 3 required params and an output schema. The description covers the core purpose but lacks behavioral details (e.g., idempotency, error handling, authorization). Adequate but not complete.

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 descriptions cover the parameters (video, user, permission) with clear types and enum values. The description adds no extra meaning beyond what the schema already provides, 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?

Description clearly states the action (create), resource (permission), and target (user on a video). It is specific and distinguishes from sibling tools like edubase_get_video_permission and edubase_delete_video_permission.

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?

No guidance on when to use this tool vs alternatives. Does not mention prerequisites (e.g., video and user must exist) or what happens if permission already exists. The description is minimal.

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