set-permission

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

The description merely restates the mutation function without any behavioral context such as overwrite behavior, prerequisites, or side effects. Annotations indicate readOnlyHint=false and openWorldHint=true, providing minimal additional insight.

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?

At only 6 words, the description is too terse for a tool with 5 required parameters and no schema documentation. It sacrifices necessary detail for brevity.

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?

Given the complexity of the operation and the lack of output schema, the description is incomplete. It omits critical context such as parameter formats, required user/vhost existence, and typical use cases.

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?

With 0% schema description coverage, the description should explain the meaning of parameters like configure, write, and read, but it does not. It fails to compensate for the schema's lack of property descriptions.

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 it sets permissions for a user in a vhost, but it does not distinguish from the sibling tool 'set-topic-permission', which has a similar purpose for topic permissions.

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 like 'set-topic-permission', 'delete-permission', or 'get-permission'. The agent is left to infer from the name alone.

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