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

With no annotations, the description carries the disclosure burden. It adds that authentication is via a project API key, which is useful. But it doesn't state whether this is read-only (implied by 'get'), pagination behavior, or result size; the mention of McpGetReleaseDetailsRequest/Response is a naming reference, not behavioral context.

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?

Single dense sentence that front-loads what is returned, followed by the parameter and usage notes. It is information-dense but not wasteful, though the McpGetReleaseDetailsRequest/Response parenthetical is low-value for an agent.

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 single-parameter read tool with no annotations and no output schema, the description does reasonably cover return payload shape and usage context, but leaves gaps on parameter format and behavioral traits like rate limits or result size — an agent could invoke it but with unresolved uncertainty.

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?

One parameter with 0% schema description coverage, so the description must compensate. It provides a hint ('version/label') and a CLI flag mapping (--version), but doesn't clarify the accepted format (semantic version, tag, branch name) or whether 'label' is an accepted alias.

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 (fetch) and resource (gate-oriented release details) and enumerates the returned data scope (priority×status stats, issue stats, scan summaries, scenario/issue records). It is somewhat differentiated from a sibling get-release, but the distinction between the two isn't made explicit.

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?

Explicitly states usage context: 'Use for CI/agent release gating.' This tells the agent when to reach for this tool. However, it does not mention when NOT to use it or name the alternative sibling (get-release) for non-gating needs.

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