CustomerFeedback_getItemReviewTrends

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

With no annotations, the description must carry the behavioral burden. It discloses that the operation is a retrieval ('Retrieve'), the time window ('past six months'), the polarity split ('positive and negative'), and a notable execution constraint ('Runs in your Kuudo deployment, not here'). This goes well beyond a minimal definition, though it does not describe output format or invocation mechanics.

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 short, but not every sentence earns its place. 'Catalog entry.' is a redundant label that adds no value. 'Runs in your Kuudo deployment, not here' is useful context, and the retrieval sentence is clear. The main verb is not front-loaded, and the cryptic deployment phrase could be clearer.

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?

Given no output schema, no annotations, and an empty input schema, the description gives the core purpose and time range but leaves ambiguities: how the item is identified, what the trend data actually looks like, and what 'runs in Kuudo, not here' means for a caller. It is minimally viable for a zero-parameter tool but not fully complete.

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?

There are zero defined parameters, so the baseline is 4. The description does not need to explain individual parameters, and the schema's 100% coverage is trivial. However, it does not clarify whether the item is identified via context, hidden properties, or no input at all, which is a minor gap given additionalProperties is true.

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 uses a specific verb 'Retrieve' and names the exact resource: an item's positive and negative review trends for the past six months. It distinguishes itself from sibling tools like getBrowseNodeReviewTrends by explicitly saying 'item' rather than 'browse node', and from getItemReviewTopics by focusing on 'trends' rather than 'topics'.

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?

No guidance is given about when to use this tool versus alternatives. The description does not mention when to choose this over related tools, nor does it state any exclusions or prerequisites. The deployment note is not usage guidance.

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