ew_sections

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

With no annotations, the description bears the burden of behavioral disclosure. It usefully discloses that the result is 'complete', 'public', and represents a navigation section inventory. It does not discuss output shape, caching, or other quirks, but for a simple no-parameter read operation the provided detail is acceptable.

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 two sentences with no filler: the purpose is front-loaded ('Get Entertainment Weekly sections') and the second sentence adds the key scoping detail about completeness and /ew/headlines compatibility.

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 zero-parameter, read-only tool without an output schema, this description is nearly complete: it names the source, the scope, and the downstream use. It could go further by explicitly describing the return value format, but the phrase 'section inventory accepted by /ew/headlines' strongly implies a list of section identifiers, which is sufficient for an agent to call the tool correctly.

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 baseline for this dimension is 4. The description adds useful context by explaining that the returned inventory is what /ew/headlines accepts, which indirectly clarifies the meaning of the tool's output values even though there are no parameters to document.

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 a specific verb ('Get') and resource ('Entertainment Weekly sections') and further specifies the exact scope: the complete public primary-navigation section inventory. This clearly distinguishes ew_sections from sibling tools like ew_article, ew_headlines, and ew_news.

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 implicitly routes usage by noting this inventory is 'accepted by /ew/headlines', so an agent knows to call this tool to obtain valid section values for headlines. It gives clear context for when to use it, though it does not explicitly state when not to use alternatives.

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