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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=false, so the safety profile is known. The description adds nothing beyond that: it does not say what is overwritten, whether the rollback is reversible, whether active traffic drops during the switch, or what authorization is required. For a destructive mutation, that is a substantial gap.

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?

A single, front-loaded sentence with no filler, so it is structurally clean. It is too thin rather than too long, which keeps it from being an example of strong concise specification.

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?

Output schema exists so return values need no explanation, but for a destructive, three-required-parameter operation with zero schema coverage, the description leaves the agent without enough to invoke it confidently. It should identify the parameters' roles and the side effects of the rollback.

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 burden falls on the description, which mentions neither environmentName, versionId, nor apiId by name. It loosely implies an environment and a target version but omits apiId entirely and gives no format or enum context (dev/test/prod) beyond what the schema already declares.

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?

States a specific verb (rollback) and resource (environment to a previous version), which is clearly distinguishable from generic siblings like api_get or secret_list. However, it does not differentiate itself from the closely related deployment_undeploy, deployment_promote, or deployment_deploy siblings, leaving the agent to infer the distinction.

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?

No guidance on when to roll back versus using deployment_undeploy, deployment_promote, or deployment_deploy. No prerequisites, no mention of required prior state (e.g., that a target version must already exist), and no exclusions are given.

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