get_housing_stats

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

No annotations provided; description states data source and that county is optional, but lacks details on failure modes (e.g., missing state), auth requirements, rate limits, or side effects. Adequate but not fully transparent.

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?

Description is relatively concise, but uses a Python docstring-style argument list which could be more prose-like. Still, it's clear and front-loaded with purpose.

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?

Covers core purpose and parameters well, but lacks usage guidelines and behavioral details. Since output schema exists, return values are covered. Overall adequate but could be more 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 has 0% description coverage; description adds meaning: state can be name or abbreviation with examples, county is optional 3-digit FIPS code with example. This is helpful beyond the bare 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?

Clearly states it retrieves housing statistics for US state/county, lists specific metrics (median home value, rent, vacancy rates, owner-occupied percentage), and identifies data source (US Census ACS 5-Year survey). Distinct from siblings like compare_areas or get_cost_of_living.

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?

Implies use case for obtaining housing stats but provides no explicit guidance on when to use this tool vs siblings like compare_areas or get_area_demographics. No 'when not to use' or alternatives mentioned.

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