property_report

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

No annotations are provided, so the description carries the full burden. It implies a read-only operation by name and returns data, but does not explicitly state behavioral traits (e.g., external API calls, potential latency, rate limits, or permission requirements). A score of 3 reflects adequate but not fully transparent behavior disclosure.

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?

Four sentences with no redundancy. The main purpose is front-loaded in the first sentence, and subsequent sentences add necessary context about requirements and alternatives. Every sentence earns its place.

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 the complexity (6 parameters, no output schema, no annotations), the description lists key return data types (sale history, area comps, EPC, rental yield, etc.), providing a solid overview. However, it does not describe output structure, pagination, or how to interpret results, which would make it more complete. Still, it is adequate for an agent to understand what the tool returns.

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 description coverage is 100%, so the baseline is 3. The description does not add significant meaning beyond what the schema already provides (e.g., it mentions 'street address + postcode' but that matches the required parameter's description). No extra context for optional parameters like include_rentals or search_radius.

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 opens with 'Full data pull for a UK property in one call' and enumerates specific data categories (sale history, area comps, EPC, rental yield, etc.), clearly defining the tool's function. It also contrasts with siblings by noting postcode-only queries should use property_comps or property_yield, distinguishing it effectively.

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?

Explicitly states when to use full address vs. postcode-only, and directs to alternative tools: 'Postcode-only... use property_comps or property_yield for postcode-only queries.' This provides clear guidance on appropriate usage scenarios and alternatives.

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