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

Annotations only declare readOnlyHint and openWorldHint; the description goes well beyond by disclosing the pagination cap (max 42, 24 per page), default ordering when sort is omitted, and the failure mode that an unrecognized/blocked path returns an upstream error rather than an empty result.

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?

Purpose and payload lead, parameters follow in order, and no sentence is filler. It is a dense single paragraph rather than a structured list, which slightly hurts scanability for a description this information-rich.

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?

With an output schema present the description need not explain returns, yet it still summarizes them, and it covers every parameter plus error and pagination behavior. An agent has everything needed to call it 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?

Schema description coverage is 0%, so the description carries the full burden and delivers: path format with a concrete example and accepted URL variants, the complete sort enum, and page indexing/default/max. All three parameters are fully specified in prose.

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') and resource (a Home Depot category/brand page's product grid), and enumerates the exact payload: normalized products plus total count and refinement facets. This clearly distinguishes it from homedepot_search (query-based) and homedepot_product (single item).

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?

Gives clear context for use (category/brand page browsing) and explains the facet drill-down loop by noting facet paths are reusable as this tool's own path. However, it never explicitly contrasts with siblings like homedepot_search or homedepot_categories, leaving the selection boundary implicit.

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