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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only states the action and affected fields; it does not disclose partial-update semantics, that description can be set to null, what happens if the id does not exist, or whether the operation overwrites fields.

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, front-loaded sentence with no filler or redundancy. It is appropriately sized for the simple update operation, though it is terse enough to leave some context gaps.

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 no annotations and no output schema, the description is thin. It does not mention that this updates an existing bank, that omitted fields are likely left unchanged, that id is required, or what the operation returns. It is minimally adequate but leaves key invocation context unexplained.

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?

With 0% schema description coverage, the tool description must compensate. It maps 'rename' to the name parameter and 'change its description' to the description parameter, but it does not explain the required id parameter or the null/optional behavior of description. The field names are self-explanatory, providing some additional meaning.

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 specific verbs 'Rename' and 'change its description' and clearly identifies the resource (question bank) and the fields affected. It clearly conveys an update operation, and the scoped wording distinguishes it from create/get/list siblings, though it never names them explicitly.

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 given on when to use this tool versus alternatives such as create_question_bank or update_question_bank_item. The description implies it edits an existing question bank's metadata, but it provides no exclusions, prerequisites, or explicit routing to sibling tools.

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