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

With no annotations at all, the description carries the transparency burden and does disclose key behavior: it filters by category/budget/free-tier and ranks by WireTensors rating. It does not mention rate limits, output shape, or pagination, but for a read-only recommendation tool those omissions are minor.

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 dense sentence that front-loads the purpose, provides a concrete example, and includes the filtering and ranking mechanism without any filler.

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 an all-optional-parameter, read-only recommendation tool, the description plus schema covers most invocation needs. The main gap is that `limit` is undocumented and there is no output schema, so the exact returned shape is left implied.

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 40%, so the description needs to compensate. It adds semantics for category and free_tier and the example maps budget/category usage, but `limit` is never explained, leaving a key aspect of the ranked response ambiguous.

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 ('Get') and a specific outcome ('a ranked recommendation'), with a concrete example. It distinguishes itself from siblings like search_tools and compare_tools through the ranked-recommendation angle.

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?

Clearly states the usage context: use when a user wants a ranked recommendation filtered by category/budget/free-tier. It does not explicitly name alternative siblings or give a when-not-to-use statement, so it misses the top tier.

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