kaiten_create_subcolumn

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

With no annotations provided, the description carries the full burden of disclosing behavior. It states only the basic effect of creating a subcolumn and does not mention required permissions, whether the parent column is modified, what response is returned, or any side effects of optional parameters like col_count.

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 front-loaded sentence with no filler or repetition. It is economical, though extremely sparse; there is no wasted text, but it also makes no effort to elaborate beyond the core purpose.

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 create operation with five parameters and no output schema, one sentence is insufficient context. The description does not explain how col_count, wip_limit, and sort_order behave, what the tool returns, or how it relates to the overall column/subcolumn workflow among the many siblings.

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?

The input schema covers all five parameters with descriptions, so the description adds no additional parameter meaning. Baseline 3 applies because schema coverage is 100% and the description does not contradict or enrich the schema.

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 action (create) and resource (subcolumn) with a locational qualifier ('inside a Kaiten column'), which clearly distinguishes it from sibling tools such as kaiten_create_column or kaiten_update_subcolumn. Although terse, it leaves no ambiguity about what operation is being offered.

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 about when to choose this tool over kaiten_create_column or how it relates to kaiten_list_subcolumns and kaiten_update_subcolumn. The verb and noun imply a usage context, but the description does not state prerequisites, exclusions, or alternatives.

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