atcCustomizing

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

With no annotations, the description carries the full burden of behavioral disclosure. The verb 'Retrieves' implies a read-only operation, but it does not explicitly disclose absence of side effects, authentication requirements, return format, or error handling. The behavior is implied but not sufficiently detailed.

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, 'Retrieves ATC customizing information,' which is concise and front-loaded with the key verb and object. It contains no filler words and is appropriately sized for a simple tool.

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 simplicity (no parameters, no output schema), the description provides a minimal but adequate conceptual understanding. However, it does not specify the structure or content of the returned 'customizing information,' leaving ambiguity that an output schema or more detail could resolve.

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 tool has zero parameters, and the schema confirms this. The description does not need to clarify parameter semantics, and it adds no conflicting details. The baseline of 4 applies because there are no parameters to leave undocumented.

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 uses the specific verb 'Retrieves' and identifies 'ATC customizing information' as the resource, but this is vague and does not distinguish from sibling ATC tools like atcCheckVariant or atcWorklists. The phrase 'customizing information' could refer to many different aspects of ATC configuration.

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 tool versus alternatives. The description only states what it does, with no mention of scenarios, prerequisites, or exclusions. It does not help the agent decide between this and related ATC tools.

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