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

Annotations already declare destructiveHint: true and readOnlyHint: false, but the description adds no behavioral context beyond what annotations provide. It does not explain any side effects, permissions required, or why the operation is considered destructive. With zero added context, the transparency is limited.

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 and the first sentence largely repeats the title, making it slightly redundant. The second sentence adds minimal new information. It is concise but not maximally efficient; every sentence should earn its place, and the repetition does not.

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 nested objects and no output schema, the description is too sparse. It does not explain the request body structure, required fields (name is required per schema), or what the response might be. The schema provides some detail, but the overall context remains incomplete.

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 description coverage is 0% for the top-level parameters, and the description only mentions 'name and description attributes' without explaining instanceId, request headers, or the body structure. The nested schema does provide descriptions for name and description, but the tool description does not compensate for the undocumented parameters.

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 clearly states the tool's purpose: creating a new snapshot for an instance. It uses specific verbs ('create') and identifies the resource (snapshot) and target (instance), distinguishing it from sibling tools like updateSnapshot, deleteSnapshot, or rollbackSnapshot.

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, nor does it mention any prerequisites (e.g., instance must exist) or conditions. It simply states the action without contextual usage clues.

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