create_checklist

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

No annotations are provided, so the description must carry the transparency burden. It does state the core side effect (creating a checklist), which is a mutation. However, it does not disclose permissions, reversibility, or response format. For a simple create tool, this is acceptable but not rich. The description adds the tracking context but lacks deeper behavioral detail.

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 short sentences that immediately state the action and usage context. It is front-loaded with the most important information, and every word earns its place with no redundancy or filler.

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?

Given the simple create operation, the 100% schema coverage, and the presence of sibling tools for context, the description is sufficiently complete. It clearly conveys what the tool does and when to use it. A small gap is the lack of mention of the idChecklistSource copy-from capability, but that is documented in the schema, so this does not significantly detract.

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 100%, with all six parameters (pos, name, cardId, fields, detailLevel, idChecklistSource) having descriptions. The tool description does not add further parameter-level meaning, but the baseline for full schema coverage is 3, which is appropriate. The description does not compensate for or extend the schema info.

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 ('Create a new checklist') and the target resource ('on a card'). It also adds purpose ('for tracking subtasks'), which distinguishes it from sibling tools like create_checkitem (which adds items to a checklist) and update_checklist (which modifies an existing checklist).

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 includes explicit guidance: 'Use this tool when you need to add a new checklist to a card for tracking subtasks.' This provides a clear usage context. It does not mention alternatives or exclusions, but the sibling tool list makes the distinction obvious (e.g., create_checkitem for items within a checklist), so a 4 is appropriate.

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