redfin_estimate

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

Description discloses it's a 'faithful pass-through' of Redfin's public AVM and historical data resources, indicating read-only behavior and source. No annotations provided, so description carries full burden; it adds useful behavioral context.

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: first states purpose and outputs, second adds backend context. Efficient, no redundancy, but could be slightly more concise.

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 a simple one-parameter tool with no output schema, description adequately lists return data and backend nature. Lacks details on property facts scope but otherwise complete.

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 already describes 'property_id' as 'Redfin property id' (100% coverage). Description does not add further meaning or examples, meeting baseline without enhancement.

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?

Description clearly states the tool returns the Redfin Estimate for a property, listing specific data points (current estimate, property facts, monthly history with comparatives). It distinguishes itself from sibling tools like redfin_property by focusing on the estimate and historical data.

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?

No explicit guidance on when to use this tool over alternatives such as redfin_property or redfin_search. Usage context is implied but not stated.

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