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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed world). The description adds useful behavioral detail – results are sorted 'most above first' and the ceiling order is cited – but says nothing about empty-result behavior, result limits, or pagination, leaving real gaps.

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 filler; the ordering guarantee is placed at the end where it belongs. Slightly dense but every clause carries information.

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 simple one-parameter read tool with no output schema, the description covers the domain, the sort order, and a key output element (cited ceiling order). It would be stronger with a note on result limits or what happens when no packs exceed the ceiling.

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 100%, and the single parameter's schema description ('brand, company or molecule') is essentially repeated by the tool description. No additional semantics such as matching rules or examples are provided, so baseline 3 applies.

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 precise resource – price-controlled packs whose filed MRP per unit exceeds the NPPA ceiling plus GST – which an agent can distinguish from siblings like compare_prices or get_brand. It lacks an explicit action verb (list/report), but the domain scope is specific enough to be unambiguous.

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?

Usage is implied by the domain (compliance/pricing checks), but there is no explicit when-to-use or when-not-to-use guidance and no reference to the alternative siblings such as compare_prices. The 'by brand, company or molecule' phrasing hints at input modes but does not instruct.

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