deployment_get_deployment_action

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is fully covered. The description adds only that a single action object is returned, with no note on auth requirements, error behavior when an ID is unknown, or whether the action may be stale. No contradiction with 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?

Three short, front-loaded lines with no filler. The final line repeats the HTTP path already present in the annotation title, which is mild redundancy but not harmful.

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 read-by-ID tool with full schema coverage, presented annotations, and no output schema, the minimum needed to invoke it is present. However, since no output schema exists, one line about what the returned action contains (or that it mirrors the entries from deployment_get_deployment_actions) would materially help an agent use the result.

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 both parameters are already documented with type/format (deploymentId is a uuid, actionId a string). The description restates them as 'Deployment ID and Action ID' without adding value such as where to obtain an actionId or that it comes from the deployment actions listing — 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 gives a specific verb+resource ('Fetch deployment action') and clarifies it is the single-action form scoped by Deployment ID and Action ID. This is enough to separate it from the plural list sibling deployment_get_deployment_actions, though it never names or contrasts that sibling explicitly.

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 deployment_get_deployment_actions, deployment_get_resource_action, or deployment_submit_deployment_action_request. The only implied condition is 'you already have both IDs', which the agent must infer from the path template.

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