gateway_knowledge_space_set_permission

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

Annotations carry no safety hints, so the description must disclose behavior. It indicates a mutating operation and the admin requirement, but it does not say whether the subject must already exist, whether the role is overwritten, or what role values are allowed.

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?

Two short sentences with no filler. The purpose comes first and the access requirement is stated efficiently.

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 output schema exists, so return-value documentation is not needed, but an agent still lacks critical invocation details: valid roles, whether membership is required, and how this differs from add/remove member tools. The description is too sparse for reliable use.

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 description coverage is 0%, so the description must compensate. It does not explain what 'space', 'subject', or 'role' mean beyond their names, and it adds nothing about valid role values or identifier formats beyond the schema's default.

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?

States a specific verb and resource: 'Set a member role in a group knowledge space.' This is distinct from sibling add/remove member tools, though it does not explicitly contrast itself with them.

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 admin-access requirement gives useful context for when the tool can be used, but it does not explain when to choose this tool over gateway_knowledge_space_add_member/remove_member or knowledge_member_add/remove. Usage is implied but exclusions are not stated.

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