getAtjsVersions

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

The description frames the operation as read-only by using 'Retrieve list', which is useful given that no annotations are provided. However, it does not disclose details such as ordering, whether deprecated or all versions are included, or response shape, which would be more transparent for a tool with no output schema.

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, front-loaded sentence that starts with the verb and states the resource directly. Every word earns its place, and there is no redundant or filler content.

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 no-parameter, read-only list tool, the description is mostly complete: it states what is returned and the target resource. It could be slightly stronger by noting the relationship to AT.js settings or the expected return format, but nothing essential blocks correct invocation.

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 is empty, so there is no parameter meaning for the description to add. The baseline for zero-parameter tools is 4, and the description appropriately needs no additional parameter detail.

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 clearly states a specific action ('Retrieve list') and a distinct resource ('available AT.js versions'). This uniquely identifies the tool among siblings, especially against the similar getAtjsSettings, by naming a different resource type.

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 explicit guidance on when to use this tool versus alternatives, and no alternative is mentioned. However, the resource name and description make the usage reasonably implied: an agent should use this when it needs to list available AT.js versions.

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