kaiten_update_checklist_item

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

Annotations already disclose destructiveHint=true, idempotentHint=false and readOnlyHint=false, so the safety profile is covered. The description adds genuine behavioral value by stating that null clears text, due_date or responsible_id, clarifying this is a selective partial update. It omits permission requirements and whether omitted fields are left unchanged.

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?

Two short, front-loaded sentences with no filler. The functional statement leads and the semantic caveat about null follows, though the second sentence could be slightly more explicit about what is not cleared.

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?

An output schema exists so return values need no explanation, and annotations carry the safety profile. Still, for a tool with four required identifiers and a nested changes object at 0% schema coverage, the description leaves key parameter meanings and update semantics (e.g. sort_order, omitted-field behavior) unspecified.

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 burden falls on the description, which does explain the null-clearing semantics for text, due_date and responsible_id and the meaning of checked. However it ignores sort_order entirely and says nothing about card_id, checklist_id or item_id, leaving part of the nested changes object undocumented.

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?

States a specific verb and resource (change checklist item fields) with enough precision to distinguish it from kaiten_update_checklist and kaiten_add_checklist_item. It does not explicitly name sibling tools or scope the operation, but the resource is unambiguous.

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 on when to use this tool versus alternatives such as kaiten_update_checklist (whole checklist) or kaiten_add_checklist_item. Usage is only implied by the name and the field-level language.

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