rental_rent_comparables_analysis

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states 'Analyze' but doesn't clarify whether this is a read-only operation, what permissions might be needed, if it performs calculations or data retrieval, or what the output format looks like. For a tool with no annotation coverage, this is a significant gap in transparency.

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?

The description is a single, efficient sentence with no wasted words. It's front-loaded with the core action ('Analyze comparable rents'), though it could be more structured with additional context. The brevity is appropriate but borders on under-specification.

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 no annotations, no output schema, and incomplete parameter documentation (50% coverage), the description is inadequate. It doesn't compensate for the missing structured data—failing to explain behavioral traits, output format, or detailed usage. For a tool with two required parameters and analytical complexity, this leaves critical gaps.

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 50% (one parameter has a description, one does not). The description mentions 'comparable rents' which loosely relates to the 'comparableProperties' parameter, but doesn't add meaningful details beyond the schema's description for that parameter. It doesn't explain 'unitId' or provide context on how parameters interact. Baseline 3 is appropriate as the schema does partial work.

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 'Analyze comparable rents for market analysis' states a general purpose (analyzing rents for market analysis) but lacks specificity about what the analysis entails or what resource it operates on. It distinguishes from some siblings (e.g., 'rental_add_lease') by focusing on analysis rather than creation, but doesn't clearly differentiate from other analytics tools like 'analytics_scenario_comparison' or 'property_investment_analysis' in terms of scope or output.

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 guidance is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites, context (e.g., for rental property evaluation), or exclusions. With many sibling analytics tools, this omission leaves the agent uncertain about appropriate use cases.

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