card_checklist_item_update

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

No annotations are provided, so the description carries the full behavioral burden, but it only implies a mutation via 'editing'. It does not disclose permission needs, partial-update semantics, side effects of moving via checklistId, clearing behavior via null, or what the response contains.

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 wasted words. Every listed field earns its place by signaling the tool's editing scope.

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 nine-parameter mutation tool with no annotations and no output schema, the description is too sparse. It lists editable fields but leaves out behavioral context, side effects, and guidance on when to prefer the dedicated sibling tools for checking, moving, or deleting checklist items.

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%, so the schema already documents all nine parameters in detail. The description names most editable fields but adds no syntax, caveats, or meaning beyond what the schema provides, and omits dueReminder.

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 verb ('editing') and resource ('Trello card checklist item') and enumerates the fields that can change. It is clear what the tool does, but it does not explicitly distinguish itself from sibling tools like card_checklist_item_set_checked or card_checklist_item_move.

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 phrase 'Use when editing...' provides a clear usage context for the tool. However, it gives no when-not guidance and does not name the more specific sibling alternatives for completion state or position changes.

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