unpivot_range

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

No annotations exist, so the description must reveal behavioral traits. It implies a write operation but fails to specify whether it overwrites, appends, or affects existing data, nor does it mention permissions or side effects.

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, direct sentence with no wasted words. However, it could be slightly longer to include essential context without losing 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?

Given the tool has seven parameters, no annotations, and an output schema, the description is too brief. It does not explain what 'normalized rows' means, how id_columns work, or what the output looks like.

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 coverage is 0% (no parameter descriptions in the schema), and the description adds no information about the seven parameters, their roles, or defaults. The description is completely silent on parameter semantics.

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 the tool converts a wide range into normalized rows and writes the result, matching the tool name 'unpivot_range'. However, it does not differentiate from sibling tools like 'write_range' or 'read_range'.

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. The description does not mention prerequisites, conditions, or scenarios where unpivoting is appropriate.

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