update_checklist_item

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

With no annotations provided, the description carries all responsibility for disclosing side effects. 'Update' implies mutation, but the description does not explain whether the operation is idempotent, whether it performs a partial update (only changing provided fields), or what happens if the item does not exist. This is a significant gap for a mutation tool.

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 sentence with no unnecessary verbosity. It is front-loaded and structurally simple. However, it is so brief that it borders on under-specification, though conciseness is still a positive trait.

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 tool has 5 parameters, no output schema, and no annotations, the one-sentence description is inadequate. It does not explain return values, the effect of optional parameters (e.g., whether leaving 'resolved' unset leaves it unchanged), or any behavioral constraints. The schema covers parameter names but not the tools situational expectations.

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?

The input schema has 100% coverage, with descriptions for all parameters (name, assignee, resolved, checklist_id, checklist_item_id). The description itself adds no parameter-level meaning beyond what the schema already provides, but since schema coverage is high, the baseline of 3 is appropriate.

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 clear action ('Update') and a specific resource ('ClickUp checklist item'). It distinguishes itself from sibling tools like 'edit_checklist' (which updates the checklist itself) and 'create_checklist_item' (which creates a new item). However, it does not enumerate the updatable fields, which would enhance clarity.

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. There is no mention of prerequisites, such as needing an existing checklist item, or a comparison with create/delete operations. The description is purely a statement of what the tool does, leaving the agent to infer usage context.

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