Elements Get Element Columns

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

Annotations already establish read-only, non-destructive, open-world behavior, so the safety profile is covered. The description adds genuinely useful context beyond that: it auto-paginates through every page and aggregates results into entries, total, and nextPage null. It omits permission requirements, but the pagination disclosure is meaningful extra context.

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 purpose is front-loaded in one clean sentence. The second sentence is dense and jargon-heavy about Sigma's pagination internals, and part of it redundantly explains return values even though an output schema exists.

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 two-parameter read-only tool with annotations and an output schema, the description is mostly adequate, and the pagination explanation helps. However, with 0% schema description coverage, the missing parameter semantics prevent it from being fully complete.

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 two required parameters, so the description must carry the burden. It only conceptually implies workbook and element scoping ('a specific element in a workbook') and gives no parameter names, ID formats, or distinction between workbook_id and element_id, leaving a real gap.

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 names a specific verb and resource ('List columns for a specific element in a workbook'), which clearly distinguishes it from workbook-wide column listings like elements_list_workbook_columns. It stops short of naming a sibling alternative explicitly, but the scope is unambiguous.

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?

Usage is implied by the phrase 'for a specific element' — use this when you have an element_id — but the description never says when to prefer it over elements_list_workbook_columns or other column-listing siblings, nor does it state prerequisites.

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