create_update

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

No annotations exist, so the description must fully disclose behavior. It mentions HTML support but does not explain required authentication, rate limits, error behavior, or the role of the confirmWrite parameter. The write operation is implied but not detailed.

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 two sentences with no unnecessary words. Each sentence adds value: first states the action, second adds specific formatting capability. No fluff or repetition.

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?

Despite having an output schema, the description is too brief for a write tool with 4 parameters. It omits prerequisites (e.g., need itemId or parentUpdateId), required confirmWrite, and any return value hints. An agent would need to infer crucial usage details.

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?

With 0% schema description coverage, the description should compensate. It adds meaning for 'body' (content with HTML formatting) but does not clarify 'itemId' (target item), 'parentUpdateId' (reply context), or 'confirmWrite' (confirmation flag). This leaves ambiguity for half the parameters.

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 tool posts an update or reply on a monday.com item, differentiating it from listing tools like list_item_updates and creation tools like create_item. The verb 'post' and resource 'update or reply' are specific.

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 implies the tool is for posting updates or replies, but it does not provide explicit guidance on when to use it versus alternatives. For example, it does not mention that this tool is for adding comments and not for modifying item fields. No when-not-to-use or alternative tool names are given.

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