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

Beyond the annotations, the description discloses that volumes and their data are destroyed (scope of data loss), the precondition/blocking semantics, the ambiguous async outcome ('removed' or 'removing'), and that the call may interrupt for human approval. That approval interrupt behavior is not captured anywhere in the schema or annotations and is exactly what an agent needs to handle the approval parameter.

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?

Four short, front-loaded sentences with almost no filler; the destructive scope leads. Slight terseness ('holds its part') costs a little clarity, but nothing is wasted.

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 destructive, 7-parameter tool with no output schema and only 14% schema coverage, the description covers destruction scope, async results, and the approval flow well, but leaves the non-trivial multi-value parameters (every_copy, accept_volume_loss, wait_seconds) undocumented anywhere.

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 only 14%, with just 'approval' documented. Six parameters (project, version, every_copy, environment, wait_seconds, accept_volume_loss) are unexplained, and while the cascade-delete wording loosely contextualizes accept_volume_loss, the description never explains every_copy, wait_seconds, or how to resume after approval.

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 and resource (delete an Environment) and immediately scopes the operation to its cascade (its Volumes and their data). This is distinguishable from siblings like environment_show, environment_protect, or volume_remove without opening either schema.

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 precondition 'once no server runs it' gives real when-to-use guidance and the unresponsive-server clause explains a blocking case. However, no alternative is named (e.g., server_remove or volume_remove first), so the agent must infer the deletion workflow.

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