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

No annotations are provided, so the description carries the full burden. 'Browse' implies a non-mutating read against a directory, which is useful, but it says nothing about result ordering defaults, limits, or what an empty browse returns.

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 sentences, zero waste, with the capability statement front-loaded and the disambiguating condition plus examples immediately after.

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 seven parameters, low schema coverage and no output schema, an agent still lacks a picture of the result shape and how sort/limit interact with browsing. The facet coverage is decent but partial.

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 only 29%, and the description covers four of seven facets (vertical/industry, category, pricing, access model). It adds no guidance on sort, limit, or type, which are undocumented or enum-only in the schema.

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?

Specific verb ('Browse') plus resource ('the directory') and the facets being filtered. The second sentence implicitly separates it from name-based search, so an agent can distinguish it from search_listings without opening a schema.

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 an explicit use condition ('when the ask is a kind of product rather than a name') backed by two concrete example queries. It does not name search_listings as the alternative for name lookups, so routing is implied rather than stated.

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