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

The description adds only the bulk execution behavior beyond the annotations. It does not disclose any potential side effects, failure modes, or permission requirements. Since annotations already indicate a mutating operation, the description adds little extra transparency.

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, and the main purpose is front-loaded. Every word is useful and it does not waste space, but it may be too terse given the missing parameter information.

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 six parameters, no output schema, and zero schema description coverage. The description only covers the overall function and one parameter's purpose. It lacks details on required vs optional fields, return value, and usage conditions, making it incomplete for an agent to use effectively.

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 description only mentions note_ids for bulk support. The other five parameters (text, unsafe, account, checked, note_id) are not explained at all, and since the schema itself has no descriptions, the description fails to compensate. This is a major gap for a tool with six 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 adds an item to a checklist, using a specific verb and resource. It also mentions bulk support, which helps differentiate it from single-item operations. However, it does not elaborate on what constitutes an 'item' or the checklist context, so it is clear but not excessively detailed.

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 hint about bulk usage with note_ids, but it does not explicitly state when to use this tool versus alternatives like keep_update_list_item or keep_create_list. There is no guidance on prerequisites or exclusions, leaving the agent to infer usage from the tool name and siblings.

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