list_formats

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

With no annotations, the description carries the full burden, and it does add some real value: it discloses the HTTP method/path (GET /formats/), warns that the response is paginated, and explicitly states the required bearer token auth. It still omits what a 'format' object contains and how pagination is driven (the schema exposes no page/cursor parameters, which is unexplained).

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?

Front-loaded with the purpose in the first sentence, followed by tightly scoped endpoint, pagination, and auth facts. Slightly mechanical in structure but no wasted prose.

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 parameterless list tool this is close to adequate, but with no output schema and no annotations the description should describe what a format record looks like and how the claimed pagination is actually controlled, since the input schema exposes no paging arguments.

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 takes zero parameters, so the baseline of 4 applies; there are no parameter semantics the description needs to clarify.

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 ('List all available formats'), which is clear on its own. However, it never distinguishes itself from the sibling get_format, which presumably retrieves a single format, so sibling differentiation is missing.

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 call this versus get_format or any other listing tool. No prerequisites, conditions, or alternatives are mentioned; the agent must infer usage from the name alone.

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