Get a homes.com market report for a location

homes_get_market_report
Read-onlyIdempotent

Get a real estate market summary for any city, ZIP, or neighborhood: median sale price, average $/sqft, and listing count from recently sold homes.

Instructions

Fetch homes.com's recently-sold listings for a city/ZIP/neighborhood and derive a market summary: count, median sale price, and average $/sqft across the sample. Pass location — free-text (e.g. 'Brooklyn, NY', '30311'). Returns { region, slug, sold_summary, sample_sold }. Note: homes.com's sold page typically returns ~40 recent listings — this is a sample-based summary, not an exhaustive market index. Read-only.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full" returns Homes.com's payload untouched. No field projection: this server has no verified record of which Homes.com fields matter, and inventing one would risk dropping a field a caller needs.
locationYesFree-text location: city, ZIP, neighborhood

TDQS

A4.5/5.0
Behavior5/5

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

Despite annotations already declaring readOnly/openWorld/idempotent, the description adds meaningful behavioral detail: the report is sample-based with typically ~40 recent listings and is not an exhaustive market index. It also discloses the return shape and explicitly says 'Read-only', reinforcing the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and front-loaded: purpose first, then parameter guidance, return shape, and a critical caveat. Every sentence carries information and none is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter tool with no output schema, the description is complete: it explains what the tool does, how to pass location, what the response will look like, and the important sample-size limitation. Nothing an agent needs to call it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds a couple of location examples but otherwise restates what the schema already says; the `view` parameter is left entirely to the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb-resource pair: 'Fetch homes.com's recently-sold listings' and 'derive a market summary', which is unambiguous. The market-report aggregation purpose is clearly distinct from sibling tools like property lookup or search.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description makes the intended use clear: pass a city/ZIP/neighborhood to get a market summary. It does not explicitly name alternatives or exclusions, so it falls short of the 'when-not-to-use' standard, but the context is strong enough to guide selection.

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