Get store feeds

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

Beyond the readOnlyHint annotation, the description discloses a non-obvious behavioral property: feed URLs remain stable across content updates, enabling one-time fetching and scheduled downloads. It does not describe the exact response structure, but for a read-only zero-parameter tool this is a minor gap.

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 compact and front-loaded, with the core purpose in the first sentence and the useful stability behavior in the second. The trailing 'Operation: GetStoreFeeds' line is mildly redundant with the tool name, but it does not detract much.

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, the description is complete: it names the resource, lists the feed formats, and explains the key behavior an agent needs to schedule downloads. No output schema exists, but the return value is sufficiently implied by 'permanent links'.

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 of 4 applies. There is no parameter ambiguity and the description correctly focuses on the output rather than inputs.

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 ('Get') and a precise resource ('permanent links to the store's catalog feeds'), and enumerates the three feed types (ICML, YML, YML_GOODS). This clearly differentiates it from other get_* sibling tools such as get_store or get_warehouse.

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 provides clear usage context: fetch the feed URL once and reuse it on a schedule because the URL never changes. It does not explicitly name alternatives or exclusions, but no sibling feed tool exists, so this is sufficient.

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