set_role_permissions

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

No annotations are provided, so the description must cover behavioral traits. It states 'Replace' implying mutation, but does not disclose whether it fully overwrites permissions, validates entities, or requires specific permissions. Further details on side effects or constraints would be needed.

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 sentence, making it concise but potentially too brief to convey necessary details. It could be improved by adding usage context or examples without becoming overly long.

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 tool has 2 parameters, no output schema, and no annotations, the description lacks completeness. It does not explain return values, error handling, or the exact structure of the permission objects beyond what the schema provides. An agent would need additional knowledge to invoke it correctly.

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 coverage is 100% with descriptions for both parameters. The tool description adds the semantic that 'body' is the new permission list, clarifying its purpose beyond the schema's 'Role add-permission' which could imply appending. This adds moderate value.

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 'Replace permission list for a role' clearly states a specific action (replace) and resource (permission list for a role). It distinguishes from siblings like update_role (which likely updates role metadata) and set_user_roles (which sets roles for a user).

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 offers no guidance on when to use this tool versus alternatives like update_role or clone_role. It does not mention prerequisites (e.g., role must exist) or specify scenarios where replacement is preferred over incremental updates.

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