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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds genuine context beyond them: the status vocabulary (DEPLOYING, COMPLETED, FAILED) and the endpoint path, which hints at the underlying API. It does not discuss result ordering, pagination limits, or empty results.

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?

One sentence front-loads the resource and the returned fields, and the trailing 'GET /atomic/{project}/deployments' is terse and informative about the backing endpoint. Slightly dense field enumeration, but nothing is wasted.

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?

No output schema exists, but the description compensates by listing every returned field, including the status enum, which is exactly what an agent needs to interpret results. Pagination semantics and the project_id cross-reference live in the schema, so coverage is adequate overall.

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 project_id, page and per_page are already fully documented (including 'Pass the previous reply's next_page'). The description contributes nothing about parameters, which is the expected baseline when the schema does the work.

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?

Names the resource precisely ('deployments of an atomic project') and enumerates the returned fields, so it is clearly distinct from list-shaped siblings like runcloud_list_atomic_projects and from single-record fetches like runcloud_get_git_deployment. It does not explicitly name a sibling to route against, which keeps it short of a 5.

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 when-to-use/when-not guidance or named alternative; the description never explains when an agent should list deployments versus checking a single deployment or project. Pagination is only implied via the schema, not stated as a usage consideration.

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