Create product feed

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

Annotations already indicate this is a non-read-only, non-destructive, open-world operation. The description adds useful behavioral context about the scheduling requirement and the two-feed limit per catalog, but does not cover auth needs, return behavior, or error conditions.

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 waste. The core action is stated first, and the limit is appended immediately without unnecessary phrasing.

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 create tool with a nested data object and no output schema, the description gives a key business limit but omits authentication requirements, response expectations, and fuller field-level guidance, leaving the schema and annotations to carry most of the burden.

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 only 50%, and the catalog_id parameter is undocumented in the schema. The description adds a meaningful constraint about mode ('different modes') and catalog capacity, but it does not compensate for the undocumented catalog_id or explain required data fields.

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?

States a specific verb and resource: 'Create a scheduled product feed'. It also adds a meaningful scope constraint, but does not explicitly differentiate itself from siblings like update_product_feed or list_product_feeds, leaving that distinction to the base verb.

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 constraint 'max 2 per catalog, of different modes' implies when this tool is applicable, but there is no explicit when-to-use guidance or reference to alternatives such as update_product_feed for modifying an existing feed.

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