UpdateCheckClassResult

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 disclosing side effects, prerequissites, or state-transition consequences. It only repeats the update operation and reveals nothing about destructiveness, idempotency, or allowed transitions.

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 short but comes across as under-specification rather than effective conciseness. It has no structural elements like context, examples, or differentiation, and the words largely parrot the tool name.

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 mutation tool with no annotations, no output schema, and a large sibling set, this description is far too incomplete. It lacks state transition details, relation to UpdateCheckClassResults, error/return behavior, and any clue about when the tool applies.

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 zero parameters and 100% schema coverage, so there is no parameter semantic gap for the description to fill. The baseline of 4 for 0-parameter tools aplies.

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 'Update Check Result State' is essentially a restatement of the tool name, swapping 'Class' for 'State' without explaining what either means. It does not identify what a 'Check Result State' is, what states are valid, or how this differs from the near-identical sibling UpdateCheckClassResults.

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 when-to-use, when-not-to-use, or alternative guidance is provided. With many sibling update tools, especially UpdateCheckClassResults, an agent has no basis to select this tool over others.

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