list_product_feeds

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered structurally. The description adds only the scoping fact that results are limited to the account and to FULL/DELTA feeds; it says nothing about pagination, volume, or empty-result behavior, but with an output schema present that is a modest 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?

A single, front-loaded sentence with no filler; the resource and scope come first. It is appropriately sized, though it is almost too terse to carry any operational detail.

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, annotated, read-only list tool with an output schema, the essentials are largely present, so return values need not be described. Still missing are the optional-filter semantics of feed_mode and any hint about result size or pagination, which leaves the definition merely adequate.

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?

Schema coverage is 0% and the single parameter is an enum (FULL/DELTA), whose values the description merely restates without explaining whether feed_mode filters the listing, defaults to both when omitted, or behaves otherwise. It adds marginal meaning over the schema.

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 gives a specific verb+resource ("Lista catálogos oficiais FULL ou DELTA") scoped to the account, which is clearly distinct from a get-by-id tool. However it never names its closest sibling get_product_feed, so the list-vs-fetch routing is only implied by the plural name.

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 when-to-use or when-not-to-use guidance, no mention of prerequisites, and no pointer to get_product_feed for retrieving a single catalog's details. Usage is only inferable from the word "Lista".

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