dictionaries_get_geo_regions

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

No annotations are provided, so the description must disclose behavior. It only states it 'gets' entries, implying read-only, but does not confirm idempotency, side effects, or limitations like rate limits. Minimal 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?

Two sentences, first is clear and direct. The second sentence instructing to call tool_help is redundant given the input schema, but does not detract much from conciseness.

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 no output schema and 4 parameters (1 required), the description lacks detail on return format, filtering syntax, and behavior. Only high-level overview, incomplete for effective use.

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%. The description mentions filtering by 'name' and 'region IDs', but does not explain the required 'fields' parameter or the format for 'exact_names'. Insufficient to understand parameter usage.

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 clearly states 'Get GeoRegions dictionary entries', specifying the action and resource. It distinguishes from siblings like 'dictionaries_get' and 'dictionaries_list_names' by naming the specific dictionary type (GeoRegions) and mentioning optional filters.

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 on when to use this tool versus alternatives, such as 'dictionaries_get' for other dictionary types. Does not specify when not to use it or prerequisites.

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