Query the PriceAI public snapshot

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

Annotations already declare read-only, idempotent, and non-destructive behavior; the description adds that the data is cached and comes from a public snapshot feed, implying potential staleness and lack of auth. It slightly oversimplifies the 'Top 5' behavior since max_offers is configurable, but it does not contradict the annotations.

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 sentence with no filler, and the key facts are front-loaded. Every word contributes to understanding the tool's function and source.

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?

Despite rich annotations, the description omits essential calling context: how product values are specified, what preset does, what the returned offers look like, and there is no output schema to fill the gap. An agent would need additional knowledge or experimentation to use this tool correctly.

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?

With 0% schema description coverage, the description must compensate, but it only hints at max_offers via 'Top 5'. It fails to explain the required product parameter, the preset option, or the trace object, leaving an agent without enough meaning to construct a valid call confidently.

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 ('Return') and names a unique resource: cached Top 5 offers from PriceAI's read-only public snapshot feed. It clearly distinguishes the tool from siblings, none of which mention pricing, caching, or snapshots.

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 gives no guidance on when to prefer this tool over alternatives, nor does it state conditions, prerequisites, or exclusions. An agent cannot tell from the description alone which scenario calls for this tool versus a sibling.

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