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

No annotations are provided, so the description must disclose behavior itself. It mentions ranking and filtering by hospital/bus constraints but does not explain what 'pass' means, how ranking is ordered (e.g., by score, access time), what happens when no areas pass, or whether it performs any aggregation. For a tool with no annotations, this leaves significant behavioral uncertainty.

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, short sentence with no verbosity or redundancy, and it fronts the main action ('Rank'). However, it is so terse that it sacrifices informativeness; it is concise but under-specified.

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?

With 7 parameters, no schema descriptions, no annotations, and only a one-line description, the tool is insufficiently specified for an agent to call it correctly. The description fails to explain the role of the parameters, the meaning of the result, or how the constraints interact, despite having an output schema and nontrivial parameter defaults. The description carries too little context for reliable invocation.

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 0%, so the description must illuminate the parameters. It vaguely references 'hospital and bus constraints' but does not map them to specific parameters like bus_max_walk_minutes or minimum_daily_bus_trips. The meaning of region, service_day, result_limit, and candidate_limit is entirely unaddressed. The description adds essentially nothing beyond what the schema names already show.

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 states a clear verb ('Rank') and a specific resource ('market-centered areas') with explicit constraints (hospital and bus). It distinguishes from siblings like search_nearby_hospitals or search_nearby_markets, which retrieve raw data, whereas this ranks a filtered set. Some ambiguity remains about what 'market-centered' precisely means, but the core purpose is identifiable.

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 given on when to use this tool versus the sibling search tools. It does not indicate, for example, that this tool should be used to get a ranked shortlist after the user has identified areas of interest, nor does it mention any prerequisites or exclusions. The description offers no context for tool selection.

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