Create SharePoint List Column

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

The description discloses the required permission (Sites.Manage.All) but does not describe other behavioral traits such as idempotency, conflict behavior, or return value. Since annotations are absent, the description carries the burden but only partially fulfills it.

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, front-loaded, and free of fluff, though the Chinese intent line is redundant. It remains concise and efficiently communicates 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?

The tool has no output schema and no annotations; the description omits what the tool returns on success, error conditions, and any side effects other than creation, leaving significant gaps for a non-trivial operation.

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 schema provides full coverage of all three parameters, and the description only reinforces the definition parameter by mentioning it as a Microsoft Graph columnDefinition, adding little beyond 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 clearly states 'Create a SharePoint list column from a Microsoft Graph columnDefinition,' specifying the verb, resource, and input format. This distinguishes it from sibling column operations like sharepoint_update_column and sharepoint_delete_column.

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 instead of alternatives such as sharepoint_update_column or sharepoint_delete_column. The only contextual note is the required permission (Sites.Manage.All), which is not usage direction.

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