add_checklist_to_card

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states that a new checklist is created, but it does not mention what the response looks like, whether the operation requires special permissions, whether duplicate names are allowed, or how this mutation affects existing checklist data. This is a notable gap for a tool with no safety-related annotations.

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 a single, front-loaded sentence with no filler. Every word contributes to conveying the core operation, and it is easy to scan quickly.

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 description covers the essential purpose and is adequate for a simple create operation, but it is incomplete in important respects: there is no output schema, yet the description does not mention what is returned; the 'pos' parameter is not explained; and the distinction from add_checklist_item is not made explicit. Given the sibling context and missing annotation support, the description could do more.

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%, but the property descriptions are tautological ('Parameter name', 'Parameter cardId', 'Parameter pos'). The tool description adds only marginal context by indicating the checklist is added to a card and that 'name' is likely the checklist name. Since coverage is high, the baseline is 3, but the description does not meaningfully enrich the parameter meaning.

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 ('Crée une nouvelle checklist') on a specific resource ('une carte Trello'), so an agent can understand what the tool does. It does not explicitly distinguish itself from the closely related sibling add_checklist_item, though the word 'nouvelle' and the focus on the checklist itself rather than its items make the distinction inferable.

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 gives no explicit guidance on when to use this tool versus alternatives. With siblings like add_checklist_item, check_checklist_item, and delete_checklist present, the description should at least clarify that this tool is for creating a brand-new checklist, not for adding items to an existing one.

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