edubase_post_class_permission

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

The description is consistent with annotations (non-readOnly, non-destructive) but does not add behavioral context beyond the core action. It does not address idempotency (multiple calls may create duplicates) or the openWorldHint (external interaction), relying on annotations which are adequate.

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, clear sentence with no wasted words. It efficiently conveys the tool's purpose.

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?

For a simple create tool with three required parameters and an output schema, the description is minimally adequate. It could mention potential side effects (e.g., overwriting existing permissions) but overall provides sufficient context given the schema and annotations.

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% with all three parameters described in the schema. The description does not add any additional meaning or examples beyond what the schema provides, so a baseline score of 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?

The description 'Create new permission for a user on a class' clearly states the action (create), the resource (permission on a class), and the target (user), distinguishing it from sibling tools like edubase_delete_class_permission and edubase_get_class_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?

The description provides no guidance on when to use this tool versus alternatives (e.g., edubase_post_course_permission), nor does it mention prerequisites, situations where it should not be used, or behavior for existing permissions.

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