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

Annotations already declare destructiveHint=true, openWorldHint=true, and idempotentHint=true, so the safety profile is available elsewhere. The description adds useful defaulting behavior for commit_id and subdomain, but does not explain what happens to any existing published site when republishing.

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 two compact sentences with the main action front-loaded. Both sentences convey relevant information without filler.

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?

With a rich input schema, an output schema, and annotations covering safety and idempotency, the description is mostly complete for invoking the tool. A stronger definition would explicitly mention that publishing replaces or affects the currently published subdomain.

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 100%, so all three parameters are already documented in the input schema. The description restates the default behavior for commit_id and subdomain but adds no syntax or constraint details beyond what the schema provides.

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 and resource: publish a successful build on a bunstation.app subdomain. It clearly distinguishes this deployment action from sibling tools such as projects_builds_list or projects_get.

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 usage by saying it publishes a successful build, so an agent can infer it should be used after a successful build exists. However, it provides no explicit when-not conditions or named alternatives such as projects_builds_list.

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