can_manage_permissions

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

The annotation already indicates a read-only, non-destructive operation, and the description does not add meaningful behavioral details beyond that. It does not disclose what the tool returns (e.g., boolean) or how it behaves when permissions are missing, so the agent cannot anticipate outcomes beyond the basic read-only hint.

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 brief and to the point, using only two sentences without superfluous text. The inclusion of workspace_id guidance is helpful, but the brevity comes at the cost of omitting important information about other parameters, which slightly reduces effectiveness.

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 availability of sibling tools and the presence of an output schema (not shown), the description lacks essential context such as return format and target type variations. It does not explain what target_type values are valid or how to obtain target IDs, leaving the agent with insufficient information to use the tool reliably in a workflow.

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?

Only workspace_id is described (with a hint to retrieve from list_workspaces), while target_id and target_type are left completely unexplained. The schema provides no additional details (no enums or descriptions), so most parameters remain ambiguous, making it difficult to construct a valid request.

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 tool checks whether the current user can grant/revoke roles, which is a specific and actionable purpose. However, it does not elaborate on what constitutes a 'target' or how this differs from other permission-checking tools like can_read or can_edit, slightly reducing clarity in a broader toolset.

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 over sibling permission tools such as can_read, give_permission, or get_permission_targets. It does not mention any prerequisites or typical scenarios, leaving the agent to infer the selection context without sufficient direction.

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