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

Annotations already declare destructiveHint=true, idempotentHint=false, and readOnlyHint=false, so the safety profile is fully covered by structured data. The description adds only the REST endpoint mapping and says nothing about irreversibility, cascade effects on linked resources, or the confirm/idempotency gate. It neither contradicts nor meaningfully enriches the annotations.

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?

Two short sentences, front-loaded with the action and followed by the endpoint reference. Nothing is wasted and there is no 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?

For a destructive mutation, the description omits the two-stage confirm behavior and idempotency-key requirement, both of which materially affect how the call is made. Those details exist in the schema, so the agent can recover them, but the description alone is thin for the risk level involved.

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 every parameter is documented in the schema — including the important 'confirm' semantics that the tool returns a dry-run request when false. The description's path template loosely mirrors organization_id, project_id, and environment_id but adds no meaning beyond the schema, so the baseline 3 applies.

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 ('Delete an environment') and maps it to the exact REST endpoint, so the action is unambiguous. It does not distinguish this from siblings like environment.suspend, environment.create, or environment.list, but the verb 'delete' is strong enough that confusion is unlikely.

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?

There is no guidance on when to use this versus alternatives such as environment.suspend (a reversible stop) or environment.list to confirm the target. No prerequisite, caution, or ordering advice is given for an irreversible operation.

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