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

The readOnlyHint annotation already establishes this as a safe read operation. The description adds no behavioral context beyond that: it restates sort options already declared in the schema and says nothing about pagination behavior, result caps, or what the returned items contain. With no output schema present, this leaves a real gap.

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 tight sentence that front-loads the action and resource before the modifiers. Every clause earns its place and nothing is padded.

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 four-parameter, zero-required listing tool the description is workable, but it omits pagination semantics (no mention of page/pageSize defaults or limits) and provides no differentiation from search_products. With no output schema, the agent gets no hint about the shape or volume of results.

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%, so page, sortBy, category, and pageSize are all documented in the schema itself. The description's mention of ordering ('newest first or by popularity') and the optional category filter mirrors the schema but adds no new syntax or format detail. 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?

States a specific verb (browse/list) and resource (catalog) plus the available ordering and filtering options, so the agent knows this is a read-oriented listing tool. It does not, however, distinguish itself from the sibling search_products, leaving the boundary between 'browse' and 'search' implicit.

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 'Browse the catalog' and the optional category filter, giving a rough sense of when to reach for it. No alternative is named (search_products is the obvious sibling), and no when-not-to-use condition is stated.

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