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

Annotations already cover readOnlyHint, openWorldHint, and destructiveHint, so the safety profile is clear. The description adds useful behavioral context beyond annotations: it lists the exact fields returned and explicitly notes that webhook keys are not returned, which is security-relevant output scoping.

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?

Extremely concise and front-loaded: the purpose and returned fields are in the first sentence, followed by two short factual sentences. No filler or redundancy.

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-only list tool with no output schema, the description adequately explains what is returned and explicitly excludes webhook keys. Pagination is fully covered by the input schema, and annotations cover safety and openness, leaving no critical gaps.

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%, and the schema already documents both page and per_page parameters with defaults and limits. The description adds no parameter-level syntax or meaning beyond what the schema provides, so the baseline score of 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?

States a specific verb and resource ('atomic Git deployment projects of the workspace') and enumerates the fields returned (name, provider, repository, branch, auto-deploy, success/failure counts, latest deployment). This distinguishes it from the sibling runcloud_list_atomic_deployments, which lists deployments rather than projects.

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?

Provides no guidance on when to use this tool versus alternatives such as runcloud_list_atomic_deployments or runcloud_get_git_deployment. The description only states what it returns and the endpoint, leaving usage context entirely implicit.

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