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

Annotations only declare readOnlyHint and openWorldHint; the description adds real behavioral detail: 1-indexed pages, maximum 42, page size, and that an unrecognized or blocked path raises an upstream error rather than returning empty. The page-size claim ('24 products per page') conflicts with the schema's '12 products per page', which muddies otherwise good disclosure.

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?

Single dense paragraph, front-loaded with what is returned before the parameter details. Mostly earns its sentences, but the sort enumerations are repeated verbatim from the schema and the 24-vs-12 per-page claim injects noise.

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?

An output schema exists, so return values need not be explained, and the description nonetheless covers return shape, path syntax, sort, and pagination bounds. Remaining gaps are minor: no explicit sibling routing and the page-size inconsistency with the schema.

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 coverage is 100%, so the baseline is 3, but the description goes beyond the schema: it explains path accepts a /b/ segment, full URL, or /b/ path, shows a real example, and clarifies that facet paths are reusable as path. It adds meaningful semantics beyond the raw field descriptions.

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: 'Browse one page of a Home Depot category or brand page's product grid', and enumerates the returned fields (title, image, model, price, rating, facets). This is clearly distinguishable from siblings like homedepot_product or homedepot_search.

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 strong operating context: path format with a concrete example, full-URL alternatives, when to omit sort, and that faceted paths can be fed back as path to drill down. It does not explicitly say when to prefer homedepot_search or homedepot_categories over this tool, so 4 rather than 5.

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