checklist-createItem

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

With no annotations, the description must bear the full burden of behavioral disclosure. It only states the action ('adds') but does not mention permissions, side effects (e.g., whether the item appears at the end or can be reordered), error conditions (e.g., what happens if the checklist ID is invalid), or return value. This is insufficient for safe invocation.

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 very short and to the point, with no extraneous content. The tag 'Tags: Cards' is unnecessary but harmless. It could benefit from slightly more detail without becoming verbose.

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?

For a tool with two parameters (one nested) and no output schema, the description provides only the basic action. It omits context about the source checklist, the format of the title, what the tool returns, and any prerequisites or validation rules. This is insufficient for reliable agent usage.

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 description coverage is 50%; the 'checklistPublicId' parameter lacks any description, and 'requestBody' is only described as 'The JSON request body' without explaining its 'title' property. The tool description adds no parameter information, leaving the agent to infer from parameter names and constraints alone.

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 action ('Adds an item to a checklist'), using a specific verb and resource that distinguishes it from sibling tools like 'checklist-create' (creates checklist) and 'checklist-deleteItem' (deletes item).

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 versus alternatives. For example, it doesn't mention that the checklist must already exist or that this tool is for adding items (as opposed to updating or deleting them). Agents are left to infer from the tool name.

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