Catalog_GetCustomColumns

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

No annotations are provided, so the description carries the full burden. It only states it 'gets' a list, implying a read operation, but offers no details about performance, pagination, or what constitutes a 'custom column'. Minimal behavioral info.

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 extremely concise: a single sentence that conveys the purpose without any wasted words. It is front-loaded and easy to parse.

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 simplicity (no params, no output schema), the description is somewhat complete. However, it lacks any indication of what the returned list contains (e.g., column names, IDs, full objects), making it slightly incomplete for an agent that needs to interpret the result.

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?

There are zero parameters and schema coverage is 100%. The description doesn't add parameter-specific meaning, but no additional info is needed since there are no parameters.

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 'Get custom column list' clearly states that the tool retrieves a list of custom columns. The verb 'Get' and resource 'custom column list' are specific, though it does not distinguish from similar sibling tools like Catalog_GetCatalogColumns or Importation_GetCustomColumns. The tool name provides context, making it clear enough.

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 vs alternatives. There are sibling tools like Catalog_GetCatalogColumns and Importation_GetCustomColumns that could be confused, but the description offers no hints about scope or prerequisites.

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