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

Annotations already indicate the tool mutates and is not idempotent, and the description reinforces this by stating 'Mutating: changes server state.' It adds the required scope 'databases:write,' which is not present in annotations. However, it does not disclose side effects, reversibility, or what exactly a grant entails beyond the mutation.

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 compact, with each line providing distinct metadata: title, HTTP endpoint, category, required scopes, and mutation status. It is front-loaded with the core action 'Create grant' and contains no filler. It could be slightly more structured, but it is efficiently sized.

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?

For a mutating tool with an open-ended body and no output schema, the description is incomplete: it omits the request body structure, the return value, and the precise effect of a grant. While annotations cover safety aspects, they do not fill these functional gaps. An agent cannot invoke this tool correctly without consulting external API documentation.

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?

Although schema coverage is nominally 100%, the descriptions are minimal: 'id' is just labeled a path parameter, and 'body' is said to have no statically declared schema. The description does not compensate by explaining what fields or structure a grant body should contain, leaving the agent unable to construct a correct request. It defers to 'API docs' instead of providing usable semantics.

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 uses the specific verb 'Create' with the resource 'grant' and includes the HTTP endpoint, making it clear this tool creates a grant on a database. It does not explicitly distinguish itself from sibling tools, but the name and path are unique. The meaning of 'grant' is not elaborated, but the intent is evident.

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 such as the revoke sibling or other database operations. It only states the HTTP method, scopes, and mutating nature, which do not help an agent decide between grant and revoke. The usage is implied by the tool name, not explained.

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