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

The annotations already indicate destructive and non-idempotent behavior, and the description adds helpful context about the ephemeral, throwaway nature of the cloud preview. It does not explicitly mention all side effects, but with annotations the bar is lower.

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 compact and front-loaded with the main action, but the parenthetical details make it slightly dense. Overall it is efficient and avoids unnecessary fluff.

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?

The description explains what the tool does and the deployment targets but does not mention what the response contains or potential failure modes. Given the lack of an output schema, some additional return-value context would improve completeness.

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 descriptions cover 75% of parameters, and the tool description elaborates on the target parameter. However, project_uuid has no description and is required, so there is a notable gap in parameter-level clarity.

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 deploys a published version, with explicit options for target. It distinguishes itself from build_go_live, which is the alternative for permanent URLs.

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 provides guidance on when to use this tool versus build_go_live and explains the target options and defaults. It could be more explicit about when to prefer local over cloud_ephemeral, but the context is mostly clear.

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