create-fleet-deployment-upgrade

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It only states the high-level purpose and does not disclose traits such as whether it is destructive, what permissions are required, rate limits, or side effects like overwriting existing deployments. This is a significant gap for a write operation.

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 a single, concise sentence that conveys the essential purpose with no unnecessary words. It is front-loaded and efficient.

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 annotations and no output schema, the description is adequate but not comprehensive. It does not mention that the deployment can be tracked via list-fleet-deployments or canceled, nor does it explain the lifecycle of the created deployment. For a simple creation tool, it minimally covers the key information.

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% with both parameters having descriptions. The description adds no additional meaning beyond the schema; 'on matching hosts' is already implied by the filterQuery parameter description. The description does not clarify parameter semantics further.

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 tool creates a deployment for upgrading Datadog Agent packages on matching hosts. It specifies the verb 'Create', the resource 'deployment', the action 'upgrade', and the target 'matching hosts'. This distinguishes it from the sibling 'create-fleet-deployment-configure', which likely handles configuration changes.

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 the tool is for upgrading agent packages but does not explicitly state when to use it versus alternatives. No when-not or alternative guidance is provided, leaving the agent to infer context from the tool name and description.

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