role_privilege_grant

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

With no annotations, the description carries full burden. It only states 'Grant' which implies adding a privilege, but does not disclose behavior on duplicate grants, error conditions, or whether the operation is idempotent. 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 sentence, making it concise but lacking any structural components like front-loaded critical warnings or use cases. It is minimally adequate but does not earn its place with additional value.

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?

Despite having an output schema, the description does not explain return values or side effects. For a state-changing tool, it fails to address success/failure behavior or any impact on related entities, leaving the tool incomplete for informed 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 coverage is 0%, and the description adds no meaning beyond parameter names 'role_id' and 'privilege_id'. No format, source, or constraints are described, leaving the agent without critical information to correctly populate these fields.

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 'Grant a privilege to a role' uses a specific verb ('Grant') and identifies the resource ('privilege to a role'). It clearly distinguishes from sibling tools like 'role_privilege_revoke' and 'role_privileges_list', making the tool's purpose unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives, nor any prerequisites (e.g., role and privilege must exist). The description lacks explicit context for appropriate usage, leaving the agent to infer conditions.

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