set_field_geographic_role

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 disclosure. It implies mutation via 'Assign or clear', but says nothing about required permissions, what value clears a role (empty string? null?), whether the change is persisted to the workbook, or what happens to fields that don't support geographic roles.

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?

A single front-loaded sentence with no filler or redundancy. It is efficient, though its brevity reflects under-specification rather than disciplined editing.

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 annotations, 0% parameter coverage, and no enums, this mutation tool leans entirely on one sentence. The output schema covers return values, but the agent still lacks the valid role vocabulary and the clearing semantics needed to call it correctly.

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% for both required parameters, so the schema contributes nothing. The description hints that geographic_role can be cleared but never enumerates valid roles (country, state, city, lat/long, etc.) nor clarifies what 'field' must reference, leaving the most error-prone input undocumented.

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 gives a specific verb pair (assign/clear) and a specific resource (a field's geographic role), which an agent can act on immediately. It does not, however, distinguish itself from the nearby sibling set_geocoding_context, so the agent has no stated basis for choosing between them.

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?

There is no guidance on when this tool applies versus set_geocoding_context or set_field_format, and no prerequisites (e.g. the field must be a dimension of an appropriate type). The agent must infer the context entirely.

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