Create Column

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

Annotations already indicate this is a mutating, non-destructive operation. The description adds domain context ('Columns define workflow stages and help organize cards through your process') but does not disclose additional behavioral traits such as response behavior, duplicate handling, or permission requirements. No contradiction with annotations exists.

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 concise and front-loaded with the action. The color list is somewhat redundant with the schema enum, and the domain context sentence adds value but is not strictly necessary. Overall, it earns its place without being verbose.

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 rich schema with full parameter descriptions, the clear annotations, and the straightforward nature of a create-column operation, the description provides enough context for an agent to select and invoke the tool correctly. It clearly states what the tool does and how columns fit into the workflow model.

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 100%, and each parameter, including name, color, board_id, and account_slug, is well-documented in the schema. The description redundantly lists colors but does not add meaning beyond what the schema already provides, so the baseline score of 3 applies.

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 a specific action and resource: 'Create a new workflow column on a board with specified name and color.' It distinguishes this from siblings like fizzy_update_column, fizzy_delete_column, and fizzy_get_columns by emphasizing creation of a new column and its role as a workflow stage.

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?

The description gives clear context for when this tool is appropriate: when a new workflow column needs to be created on a board. It does not explicitly name alternatives or when-not-to-use conditions, but the create-vs-read/update/delete distinction is implicit and clear from the phrasing.

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