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

With no annotations, the description must carry the behavioral burden. It does disclose meaningful eligibility behavior — only published homes, and only those rated 4.3+ on Google — which an agent could not infer from the schema. However, it says nothing about result ordering, pagination, empty-result behavior, or auth requirements, leaving notable gaps for a tool with zero annotation coverage.

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?

Three sentences, each doing distinct work: identity, return/filter behavior, and usage trigger. Front-loaded and free of 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?

No output schema exists, so the description should indicate what comes back; it says published, 4.3+-rated homes but not what fields a listing carries or how results are ordered. For a read-only search with fully documented optional filters, this is close to sufficient but not fully 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 coverage is 100%, so all five parameters are already documented in detail. The description only echoes the 4.3 rating floor (the minRating default) and restates the state coverage, adding no syntax, matching, or combination guidance beyond the schema.

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 opens with a specific verb and resource ('Search Fursat's curated catalog of vacation homes') and bounds the domain to Northeast India and the Himalayas. It doesn't explicitly contrast itself with get_listing or start_inquiry, though the distinction is fairly self-evident from the names.

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?

It gives an explicit trigger: 'Use this when a traveler asks about accommodation suggestions in this region,' and lists concrete states to help the agent recognize that context. It stops short of naming alternatives or stating when not to use it (e.g., for a known property, use get_listing).

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