Start environment

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

Annotations (readOnlyHint=false, destructiveHint=false) already indicate a mutation without destruction. The description adds the 'trigger a deployment' detail, but does not disclose side effects, auth requirements, or that it may be a long-running operation. With annotations present, the bar is lowered; the description provides some added context but not enough to exceed a score of 3.

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?

Single sentence, no wasted words, front-loaded with the action. Perfectly concise for the information conveyed.

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?

Given no output schema and simple two-parameter tool, the description is minimally adequate. However, lacking details on the deployment trigger implications or return value leaves some gap. An agent might benefit from knowing if the start operation is reversible or what the response contains.

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 coverage is 100%, and both parameters have descriptions. The tool description does not add meaning beyond the schema. Baseline is 3, and no extra value is provided.

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 verb 'Start' and the resource 'environment', and adds that it triggers a deployment. This distinguishes it from siblings like 'stop_environment' and 'initiate_deployment' but does not explicitly differentiate from 'initiate_deployment'.

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 use this tool versus alternatives (e.g., 'initiate_deployment' or 'stop_environment'). No prerequisites or conditions mentioned, leaving the agent without context for proper selection.

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