get_deployment

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Get details' implies a read operation, but the description does not state side-effect-freedom, access/permission requirements, error behavior for missing deployments, or what the returned details include.

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, focused sentence with no redundant words or filler. It is front-loaded with the action and resource, making it easy for an agent to parse quickly.

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 simple two-parameter read tool, the description plus the fully documented schema provides a minimally viable definition. However, there is no output schema and the description does not clarify what 'details' includes, nor does it note that both parameters are effectively needed to identify a specific deployment.

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%, with project_id documented as 'Project ID or URL-encoded path' and deployment_id as 'The ID of the deployment'. The description adds no additional parameter meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 clear action ('Get details') and a specific resource ('a specific deployment in a GitLab project'), which makes the tool's purpose immediately understandable. It does not explicitly contrast itself with sibling list_deployments, but the phrase 'specific deployment' conveys the distinction between fetching one deployment versus listing many.

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 gives no guidance on when to use this tool over alternatives such as list_deployments or get_environment. Usage is only implied by the tool name and the idea of getting a 'specific' deployment; there are no explicit conditions, prerequisites, or exclusions.

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