update_permission_group

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

The description provides no behavioral context beyond the verb 'rename.' It does not disclose whether renaming affects group members, permissions, or existing references, nor any required permissions or side effects. Annotations indicate readOnlyHint=false (mutation) and destructiveHint=false, but the description adds no further detail, so the burden falls on the agent to infer behavior.

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 extremely concise—two sentences with no filler. The primary purpose is stated first, and the only parameter hint (workspace_id) is directly relevant. Every word earns its place.

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 that this is a required-parameter write operation with no schema descriptions, the description is incomplete. It omits meaning for name and group_id, does not clarify the scope of 'update' (whether it only renames or allows other changes), and lacks any context about return values or side effects. An output schema exists, but parameter and behavioral information are still insufficient.

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?

The schema has zero parameter descriptions, so the description must compensate. It only explains workspace_id, noting it can be obtained from list_workspaces(), but provides no meaning or constraints for name or group_id. This leaves two of three required parameters unexplained, forcing the agent to guess their purpose.

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 states a clear verb and resource: 'Rename a permission group.' This is specific and distinguishes it from sibling tools like create_permission_group, delete_permission_group, and get_permission_group. It unambiguously conveys the tool's core function.

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 gives no guidance on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or which other permission-group tools might be more appropriate in different scenarios. The only hint is about workspace_id, which is parameter help, not usage context.

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