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

Annotations already declare this destructive, non-idempotent, open-world write, and the description still adds real value: it creates URL-based bulk jobs and returns BatchId, records SubOrigin while preserving Origin=Catalog, applies token/quota validation, and strips internal-only fields before sending. It also states the confirmed=true / impactConfirmed=true gating and that channel resolution happens internally. Slight deduction because some of the disclosure reads as API-legacy noise (DelaysMap, UserDevice telemetry) rather than agent-relevant behavior.

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 resource and usage gating, which is good, but the opening two sentences about being a 'dedicated' non-generic tool are boilerplate and 'Search terms: catalog submitcatalog' is filler. The remaining content is dense and useful but delivered as one long run-on block rather than structured fields.

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 destructive, confirmation-gated mutation with an output schema available, the description covers preconditions, alternatives, body shape and side effects well enough to call it correctly. Minor gap: it does not say what happens on partial failure or whether the returned BatchId needs a follow-up poll, though the output schema likely carries the return shape.

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 already 100%, so the baseline would be 3, but the description genuinely goes beyond it by enumerating the body structure: each ProductsToList item carries exact Url, Title, SubOrigin (CatalogSelection=1 / CatalogSearch=2) and optional PublishOn, plus notes that Origin is preserved and legacy Id/DelaysMap are still accepted. That is material semantics the schema's one-line body description does not convey.

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?

Names a specific verb and resource ('Queues selected catalog candidates for publication or review' against POST api/Catalog/SubmitCatalog) and explicitly distinguishes itself from generic endpoint callers and from sibling tools like Catalog/GetProducts and Listing/SaveBulkPublish. An agent can identify the operation without opening the schema.

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?

Provides an explicit 'Use when' (after selecting real candidates from Catalog/GetProducts) plus concrete exclusions (not for discovering products, not for importing store inventory, not for ad-hoc URL publication) and names the alternative to use instead (Listing/SaveBulkPublish). This is the full when/when-not/alternative triad.

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