edubase_post_class_permission

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

Annotations already indicate this is a write operation (readOnlyHint=false). The description confirms creation. No additional behavioral details (e.g., conflict handling, permission inheritance, or rate limiting) are provided. 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?

The description is a single sentence with no waste. It is front-loaded with the key purpose. However, it could be slightly more informative without becoming verbose, hence score 4.

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 is minimal and lacks information about the expected response (output schema exists but not described), error states, or idempotency behavior. Given the tool has three required parameters and multiple siblings, more context is needed.

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?

Input schema has 100% coverage with descriptions for all three parameters. The description does not add extra meaning beyond the schema, e.g., the effects of each permission level are not explained. Baseline score of 3 applies.

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), resource (permission), and target (user on a class). It uses specific verbs and nouns, and distinguishes from sibling tools like edubase_delete_class_permission or 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 similar permission creation tools (e.g., edubase_post_course_permission, edubase_post_quiz_permission). No context on prerequisites, side effects, or when it's appropriate.

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