Create Update in Monday, after calling this tool you should

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

Annotations are all false, and the description adds minimal behavioral context beyond the obvious creation action. It does not disclose side effects, permissions, rate limits, or return format.

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 contains unnecessary procedural instructions (calling full board data tool and show table tool) that are not part of the tool's core purpose, making it longer than needed.

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 no output schema, the description should provide information about the return value, but it does not. It adequately covers parameter usage but lacks completeness in explaining the result.

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 100%, and the description adds a useful usage note about not using '@' and using mentionsList instead, which clarifies parameter behavior beyond schema definitions.

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 it creates an update (comment/post) on a monday.com item, but does not differentiate from the sibling tool 'create_update', which likely has a similar purpose.

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 on when to use this tool versus alternatives (e.g., 'create_update' or 'get_updates'). The description only includes post-call workflow instructions, not usage context.

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