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

With no annotations provided, the description carries the full behavioral burden. Stating 'Public (no key)' is useful auth context, but there is no disclosure on rate limits, response shape, error handling for missing ids, or what 'cloud' implies. For a public read endpoint, the safety profile is inferable but incomplete.

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?

Two terse sentences with zero waste. The core action is front-loaded and the public/no-key note is a compact qualifier. Nothing extraneous.

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 tool with no annotations, no output schema, and 0% schema coverage, the description is too sparse. It omits what 'cloud' means, how missing ids are handled, and any return-value guidance. An agent would struggle to call 'cloud' correctly without further context.

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%, so both parameters ('ids' and 'cloud') are undocumented in structured data. The description only hints at 'ids' via 'by ids' and gives no meaning to 'cloud' – is it a region, a provider, a filter? The description fails to 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?

States a specific verb and resource ('catalog lookup by ids'), distinguishing it from the singular 'uxc_get_product' by its batch nature. Clear enough that an agent can tell it apart from search_catalog, though the two-char 'uxc_' prefix and lack of explicit sibling comparison keep it short of a 5.

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 word 'Batch' implies usage for retrieving multiple items at once, and 'by ids' implicitly contrasts with 'uxc_search_catalog', which presumably handles non-ID queries. However, no explicit when-to-use versus alternatives is given, leaving routing to inference.

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