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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Clone' implies a write operation that creates a new role based on an existing one, but the description doesn't specify what gets cloned (permissions, users, settings?), whether authentication is required, what happens if the source role doesn't exist, or what the output looks like. This leaves significant gaps for a mutation tool.

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, efficient sentence with zero wasted words. It's appropriately sized for a tool with no parameters and gets straight to the point without unnecessary elaboration.

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 mutation tool (implied by 'clone') with no annotations, no output schema, and 0 parameters, the description is incomplete. It doesn't address key contextual aspects like what exactly gets cloned, how the source role is identified, what permissions are required, or what the result looks like. For a tool that likely creates new resources, this lack of detail is problematic.

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 input schema has 0 parameters with 100% schema description coverage, meaning there are no parameters to document. The description doesn't need to compensate for any parameter gaps, so it meets the baseline expectation. However, it doesn't explain why there are no parameters (e.g., whether the role to clone is inferred from context or requires prior setup), which slightly limits its helpfulness.

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 'Clone an existing role' clearly states the verb ('clone') and resource ('an existing role'), providing a basic understanding of what the tool does. However, it doesn't differentiate from sibling tools like 'create_roles' or 'update_role', leaving ambiguity about when to use cloning versus creating a new role from scratch.

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 alternatives. With sibling tools like 'create_roles' (create new roles) and 'update_role' (modify existing roles), there's no indication of when cloning is preferred over creating a fresh role or what prerequisites might be needed (e.g., needing an existing role to clone).

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