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

With no annotations, the description carries the behavioral burden and does well: it discloses a presigned GET URL that expires in ~15 minutes, notes that cleanUrls materialized copies are omitted when possible, and says static-hosting.json is included. It does not mention permission requirements or size limits, but the key return behavior and content quirks are covered.

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 front-loaded with the core action and output details, then adds prerequisite guidance and content caveats. Every sentence adds useful information without repetition.

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 tool with no annotations and no output schema, the description does a good job explaining the returned artifact, its expiry, and the zip contents. However, it omits any explanation of site_id and does not cover auth or access constraints, leaving meaningful gaps for a two-parameter tool.

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%, so the description must compensate. It explains only where to obtain deployment_id and says nothing about the required site_id parameter, its meaning, or its expected format.

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 states a specific verb, resource, and output format: download a deployment version as a zip. It also names the sibling list_deployments as the way to find the required deployment_id, making the tool's role clear.

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?

It explicitly tells the agent to use list_deployments to find deployment_id and gives a use case: editing and redeploying to staging. It does not state when not to use this tool or name any alternative download mechanism, so it stops short of full routing guidance.

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