create_column

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not mention required permissions, side effects, whether the column is appended in a particular position, or what the response contains. The only behavioral detail added is that color is optional and provided as a hex value.

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 brief and front-loaded with the core action. The Args section is compact and adds value for the color parameter. However, the brevity contributes to under-specification of the other required parameters, so it is not fully appropriate for the tool's complexity.

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?

With five parameters, four of them required, no annotations, no output schema, and many sibling tools, this description is too sparse. It covers only color and gives no explanation of the GitHub context (owner/repo), project identification, or column naming. An agent selecting and invoking this tool would need to infer critical details from parameter names alone.

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%, so the description must compensate by documenting parameters. It does document the color parameter with a format example, but it does not explain the required parameters: owner, repo, project_id, and title. The agent is left without guidance on what owner/repo/project_id refer to or what the title should represent.

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 states a clear action and target: 'Add a column to a project board.' This distinguishes it from sibling tools like edit_column or delete_column, though it does not explicitly contrast itself with them. The resource and verb are specific enough for an agent to understand the primary operation.

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 use this tool versus alternatives such as edit_column, delete_column, or set_default_column. The description only states what it does, leaving the agent to infer usage context from the tool name and sibling list.

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