uncomplete_checklist

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

With no annotations, the description carries full responsibility for behavioral disclosure. It mentions the action and return value but omits any side effects (e.g., whether it is a write operation, idempotency, permission requirements, or error conditions). It adds only a minimal statement about returning the updated checklist, which is helpful but insufficient for a mutation tool without annotation support.

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 compact and well-structured: a clear one-line action, an Args section, and a Returns section. Every element earns its place, and the action is front-loaded. No wasted words or redundant 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 is simple (one integer parameter) and an output schema exists, so the description does not need to detail return structure. It does state the return is a JSON string with the updated checklist, which is useful. However, it lacks any context about prerequisites (e.g., checklist must exist) or relationship to sibling tools (e.g., inverse of complete_checklist). For a simple tool, it is minimally adequate but not thorough.

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 0%, so the description must compensate. The only parameter, checklist_id, is described as 'The checklist ID' which simply restates the schema property name and adds no additional meaning (no format, examples, constraints, or relationship to other data). This is effectively redundant with the schema.

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 states a specific action ('Mark a checklist as incomplete') on a clear resource (checklist). It is the inverse of the sibling 'complete_checklist' and distinct from the more general 'update_checklist'. The purpose is unambiguous and easily distinguished from siblings.

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 no guidance on when to use this tool versus alternatives. It does not mention that 'complete_checklist' is the opposite, nor does it advise using 'update_checklist' for other fields. There is no explicit when/when-not context, leaving the agent to infer usage from the name alone.

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