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

No annotations are provided, so the description carries the full burden. It mentions 'get a list,' implying a read operation, but does not disclose behavioral traits such as authentication needs, rate limits, pagination, or what 'deployment events' entail. This leaves significant gaps in understanding how the tool behaves.

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 sentence that is front-loaded and efficient, with no wasted words. However, it is under-specified given the tool's likely complexity, but it earns a high score for conciseness as it avoids redundancy and is structurally clear.

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?

Given the tool's name suggests creation but description suggests retrieval, no annotations, no output schema, and lack of behavioral details, the description is incomplete. It fails to provide enough context for an agent to understand the tool's role, especially with sibling tools present, making it inadequate for effective use.

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?

The input schema has 0 parameters with 100% coverage, meaning no parameters are documented. The description does not add parameter details, but since there are no parameters, this is acceptable. The baseline for 0 parameters is 4, as the description need not compensate for missing param info.

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 'Use this API endpoint to get a list of deployment events,' which is a tautology that essentially restates the tool name 'create_dora_deployments_v2_2' without clarifying the actual purpose. The name suggests creation, but the description describes retrieval, creating confusion rather than providing a clear verb+resource distinction.

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 provides no guidance on when to use this tool versus alternatives. It does not mention any context, prerequisites, or exclusions, and with many sibling tools (e.g., 'get_dora_deployment', 'create_dora_deployments_v2'), there is no differentiation, leaving the agent without usage direction.

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