update_item_column_values

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

With no annotations, the description must fully disclose behavioral traits. It indicates a write operation but does not mention permissions, error conditions, idempotency, or side effects. The mutation nature is implicit, but critical details are missing.

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 extremely concise with two sentences: one stating purpose and one providing a usage hint. No wasted words, though it could be slightly more informative without sacrificing conciseness.

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 tool has 5 parameters (4 required) and an output schema, the description is insufficient. It omits the purpose of confirmWrite, createLabelsIfMissing, and how to format columnValues. The hint about board details is helpful but not enough for a complete understanding.

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 coverage is 0% with no parameter descriptions. The description adds no meaning beyond the vague 'column values'. Parameters like confirmWrite, createLabelsIfMissing, and boardId are not explained. The description fails to compensate for the lack of schema documentation.

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 the specific action: 'Update one or more column values on a monday.com item.' It uses a specific verb and resource, and the hint 'Get board details first' adds valuable context. Among sibling tools, it is distinct from rename or create operations.

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 provides a useful precondition hint ('Get board details first'), but does not explicitly guide when to use this tool versus alternatives such as update_item_name or create_update. No exclusions or alternative tools are mentioned.

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