Process a catalog feed now

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

Annotations already declare the operation is not read-only, not idempotent, and open-world, so the agent knows it causes a side effect. The description adds that the work is delegated asynchronously to Pinterest, but it doesn't say whether the call returns immediately, whether repeated calls re-fetch, or what the response contains — meaningful gaps for a non-idempotent trigger.

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?

One sentence, front-loaded with the action and contrasted against the default scheduling behavior. Nothing redundant.

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 two-parameter trigger with no output schema, the description should at least hint at the async nature of the result and how to verify processing (a dedicated sibling exists for feed processing results). Annotations cover the safety profile, but the post-call workflow is not addressed.

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 0% and neither parameter is mentioned. 'feed_id' is inferable from the tool name, but 'ad_account_id' (optional, nullable, default null) is completely unexplained in both schema and description, so the description does not compensate for the coverage gap.

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 names a specific action (triggering a fetch/processing of a catalog feed) and frames it against the default behavior (waiting for the schedule). That's enough to distinguish it from siblings like list_catalog_feeds and list_feed_processing_results, though it doesn't name them explicitly.

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?

It gives a clear trigger condition: use this when you want processing to happen now rather than on the normal schedule. It stops short of stating exclusions (e.g., don't spam repeated triggers, or use list_feed_processing_results to check the outcome afterward).

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