update_list_item

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 only states the basic mutation ('Update') and which fields are affected; it does not disclose permission requirements, whether the update is partial, idempotency, error behavior, or what happens if note_id and item_id do not match.

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 efficient sentence with no filler, front-loading the verb and the target resource. It earns its place, though there is room to add useful routing or identifier context without bloating it.

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?

With no annotations, 0% schema coverage, and only a one-sentence description, the definition is incomplete for a tool with four parameters and required identifiers. Even though an output schema exists, the agent lacks guidance on identifiers, usage boundaries, and behavioral 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?

Schema description coverage is 0%, so the description must compensate. It adds meaning for text and checked by saying they are the mutable item properties, but it says nothing about note_id or item_id, which are required and ambiguous without further context such as where the IDs come from.

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 verb 'Update', the resource ('a checklist item'), and the updatable fields ('text and/or checked state'). It is distinguishable from add and delete list item siblings, though it does not explicitly name those alternatives.

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 intended use is implied: use this when you want to change an existing checklist item's text or checked state. However, the description gives no explicit guidance on when not to use it or how it relates to siblings like add_list_item, delete_list_item, or update_note.

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