Importation_GetCustomColumnExpression

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

Description mentions the expression is 'encrypted' but lacks other behavioral traits like permissions needed, side effects, or return format. With no annotations, the description should provide more transparency.

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?

Single sentence, no unnecessary words. Perfectly concise.

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?

For a read tool with no parameters and no output schema, the description is functional but minimal. It does not clarify what the return value represents (e.g., a string) or how it relates to importation state.

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?

No parameters exist, so the description does not need to add param info. Baseline for zero parameters is 4; the description is adequate.

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?

Description clearly states the action (Get) and the resource (encrypted custom column expression) within the importation context. It differentiates from sibling tools like Catalog_GetCustomColumnExpression by specifying 'in this importation'.

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 Importation_GetCustomColumns or Catalog_GetCustomColumnExpression. The description does not specify prerequisites or context.

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