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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly states this is a listing operation, enumerates the exact values returned, and specifies the output fields. For a simple, parameterless, read-only tool, this is sufficient. It does not discuss rate limits or data freshness, but those are minor for a static list tool.

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?

Two sentences with no wasted words. The primary action is front-loaded ('List The Atlantic sections'), followed immediately by the key relationship to /theatlantic/headlines and the value enumeration. Every sentence earns its place.

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 parameterless list tool with no output schema, the description is complete. It states what the tool returns (slug, display name, landing-page URL), enumerates all values, and connects the tool to the headlines endpoint. An agent has everything needed to call and interpret the result.

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, so the schema is trivially complete. The description adds no parameter-specific information, but none is needed. Baseline 4 for a parameterless tool is appropriate.

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 a specific verb and resource: 'List The Atlantic sections.' It further clarifies scope by stating it lists every top-level section accepted by /theatlantic/headlines, and names the exact fields returned (slug, display name, landing-page URL). This clearly differentiates it from the many other section-listing tools in the sibling list.

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 implies usage: it tells the agent these are the sections accepted by /theatlantic/headlines, so an agent can infer this tool is for obtaining valid section values for that endpoint. However, it does not explicitly state when to use this tool versus alternatives or mention any exclusions. The context is clear but the guidance is implied rather than stated.

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