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

No annotations are provided, so the description bears full burden. It does not disclose any behavioral traits like pagination limits, rate limits, authentication requirements, or whether results are sorted by relevance. It appears read-only but is not explicitly stated.

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?

The description is efficient, front-loading the purpose, then listing outputs and use cases. It is well-structured without fluff, though could be slightly more concise in listing fields.

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?

Given there is no output schema, the description compensates by listing many returned fields. It addresses purpose, parameters, use cases, and sibling tool. However, it lacks details on error handling, result limits, and data freshness.

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% for all 3 parameters. The description adds minimal value beyond the schema by mentioning zipcode, type, and pagination, but the schema already describes them clearly. No defaults or constraints are clarified.

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?

The description clearly states the tool retrieves Redfin real estate listings by zipcode with pagination, listing many attributes. It distinguishes itself from sibling tools like the property details endpoint by mentioning it returns summary data and can be used to feed URLs into that endpoint.

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?

The description provides explicit use cases such as market research, lead generation, trend analysis, and even suggests a sibling tool for deeper details. However, it lacks explicit when-not-to-use guidance.

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