create-volume

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

No annotations are given, so the description must fully disclose behavioral traits. It only states the basic action without detailing side effects, idempotency, failure modes, or dependencies like billing or existing volume conflicts.

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 concise sentence that efficiently conveys the tool's purpose without superfluous words. However, it could benefit from slightly more structure to highlight key aspects.

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 creation tool with no output schema, the description lacks details about return value (e.g., volume ID) or post-creation state. It fails to address common agent needs like confirmation of success or error handling.

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?

Input schema has 100% coverage with descriptions for all three parameters. The description adds no additional meaning beyond what the schema provides, meeting the baseline for adequate parameter information.

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 action (create) and resource (persistent storage volume) with context (in a Bult project for apps, databases, cloud hosting). It effectively distinguishes from sibling tools like delete-volume or update-volume.

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 implies when to use (creating a volume) but provides no explicit guidance on when not to use or comparison with alternatives like deploy-project. No prerequisites or preferences mentioned.

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