edubase_post_video_permission

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

The description states 'create', which implies mutation, aligning with annotations (readOnlyHint: false). However, it does not disclose behavioral details such as whether existing permissions are overwritten, required user roles, or side effects. With annotations present, the description adds minimal extra context beyond the annotation values.

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 with no wasted words. It is concise and front-loaded with the action. However, it could be slightly more informative without sacrificing conciseness.

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 is simple with three required parameters and an output schema (though not shown). The description covers the basic purpose but does not mention the return value or any post-create behavior. For a straightforward tool, it is minimally complete but could be improved.

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 three parameters are documented in the input schema with clear descriptions and an enum for permission. The description does not add any new meaning beyond what the schema already provides. Since schema coverage is 100%, a score of 3 is appropriate per guidelines.

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 action 'create' and the resource 'permission for a user on a video'. It distinguishes from sibling tools like 'edubase_delete_video_permission' and 'edubase_get_video_permission' by indicating a creation operation. However, it does not specify the scope or uniqueness among other permission creation 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?

No guidance is provided on when to use this tool versus alternatives (e.g., edubase_post_class_permission). There is no mention of prerequisites, conditions for use, or when not to use it. The description lacks context for correct selection.

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