AVnester — Indian Real Estate Intelligence

Compare AVnester properties (trade-offs)

compare_properties

Read-onlyIdempotent

Compare 2–5 AVnester listings by listingId, side-by-side. Get IDs from search_properties first (not guessable). If the user has more than 5 candidates ("compare all"), pick the most relevant 5 (cheapest / largest / best ₹/sqft) and say so. Returns each listing plus pricePerSqft, vsCheapestPercent (0 = cheapest), vsLargestAreaPercent (0 = largest). Unknown IDs return not_found_or_unpublished. Does NOT recommend a purchase. Show verification.caveats with verified. Always surface the disclaimer.

A4.9/5.0

Behavior5/5

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

Annotations declare read-only/idempotent safety, and the description adds behavioral context the annotations cannot: unknown IDs return not_found_or_unpublished, output includes derived fields (pricePerSqft, vsCheapestPercent, vsLargestAreaPercent), it does NOT recommend a purchase, and verification.caveats/disclaimer must be surfaced. This goes well beyond the annotation baseline.

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?

Front-loaded with the action and cardinality, then prerequisites, overload handling, output fields, error behavior, and required surfacing. Every sentence carries a distinct operational instruction; no filler.

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?

Despite high schema/annotation richness and an output schema, the description covers edge cases an agent would otherwise guess wrong: unknown-ID error string, no-recommendation constraint, and mandatory caveat/disclaimer surfacing. Nothing needed to invoke it correctly is missing.

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

Parameters4/5

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

Schema coverage is 100%, so the 3-baseline applies, but the description adds meaning beyond the schema: derivations of returned fields (0 = cheapest, 0 = largest) and order preservation, plus the ID provenance constraint. These are useful but some are output semantics rather than input semantics.

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?

States a specific verb and resource ('Compare 2–5 AVnester listings by listingId, side-by-side') and names a distinguishing sibling (search_properties) that produces the required IDs. An agent can separate this from search_properties, get_property_details, and compare_localities without opening any schema.

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

Usage Guidelines5/5

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

Explicitly states both when to use it and the prerequisite ('Get IDs from search_properties first (not guessable)'). It also handles the overload case ('compare all' with >5 candidates) by instructing the agent to pick the most relevant 5 and disclose that choice, an unusual and useful routing rule.

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