Create Product Feed

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

Annotations already establish this is a mutating, non-idempotent, non-destructive call. The description adds useful behavioral context by stating the feed 'automatically sync products from a URL' and by disclosing that the call 'Returns the new feed ID,' which is valuable since no output schema exists.

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 well-structured: a one-sentence purpose, a clear Args list, and a return statement. Every section serves a purpose and no filler appears.

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 moderately simple create operation with full schema coverage, the description covers the creation behavior, key parameters, and return value. It does not mention caveats like whether syncing begins immediately or whether the URL must be publicly accessible, but those are not essential for correct invocation.

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 description coverage is 100%, so the schema already documents all parameters. The description repeats the required parameters with slightly richer phrasing, such as file formats and interval examples, but does not add meaning beyond what the input schema provides.

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 opens with a specific verb and resource: 'Creates a new product feed for a catalog.' It also clarifies the purpose by saying the feed will 'automatically sync products from a URL,' which distinguishes it clearly from sibling read/list/delete feed tools like meta_list_product_feeds.

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 clearly frames when this tool is appropriate: when creating a new product feed that syncs from a URL. It does not explicitly name alternatives or exclusions, but the 'new' wording and sync behavior provide enough context for an agent to route correctly.

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