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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It mentions functions like 'geocode' and 'validate' but doesn't disclose critical details such as rate limits, authentication needs, data sources, error handling, or whether operations are read-only or mutative. This leaves significant gaps in understanding how the tool behaves.

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 very concise—a single phrase listing functions—which is efficient and front-loaded. However, it's arguably too brief, bordering on under-specification, as it sacrifices clarity for brevity by not elaborating on any aspect.

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 tool's apparent complexity (multiple functions, no output schema, no annotations, and a generic parameter object), the description is incomplete. It fails to address how to invoke different operations, what results to expect, or how it integrates with sibling tools, making it inadequate for effective agent use without additional context.

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?

The input schema has 100% description coverage but only documents a generic 'params' object as free-form, providing no semantic meaning. The description doesn't compensate by explaining what parameters are needed for each function (e.g., what inputs for normalize vs. geocode), leaving parameters effectively undocumented despite the schema coverage.

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 lists multiple functions (normalize, parse, validate, geocode, postal lookup) which gives a general sense of purpose, but it's vague about what specific resource or data type it operates on. It doesn't clearly distinguish this tool from its sibling 'k_address_geocoder', which suggests overlapping functionality without clear differentiation.

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 like 'k_address_geocoder' or other siblings. The description merely lists functions without context about appropriate use cases, prerequisites, or exclusions, leaving the agent to guess based on tool names alone.

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