タスクリスト名の変更

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It only states the action of renaming without mentioning side effects (e.g., impact on tasks, permission requirements, error behavior if the tasklist does not exist, or queuing/move semantics). This is a minimal disclosure 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, concise sentence in Japanese that efficiently conveys the core purpose. It is appropriately front-loaded and contains no filler. However, it is so brief that it misses an opportunity to add contextual value, though it does not waste words.

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 simple rename operation with full schema coverage and no output schema, the description is minimally adequate—it states the primary action. Yet it omits any mention of limitations (e.g., only the name changes, not other list properties) or prerequisites, which could be important for correct invocation. It does not introduce confusion, but it leaves room for richer context.

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%, with both 'title' and 'tasklist' already documented clearly. The description adds no new parameter information beyond what the schema provides. Since the schema fully explains the parameters, 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 'タスクリストの名前を変更する' clearly states a specific verb (change) and a resource (tasklist name), which distinguishes it from sibling tools like create-tasklist, delete-tasklist, and update-task. The title reinforces the exactly-scoped purpose, so an agent can correctly identify what the tool does without ambiguity.

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 provides no guidance on when to use this tool versus its siblings. It does not mention any conditions, exclusions, or alternatives, leaving the agent to infer that this is the right tool for renaming a tasklist. The only hint is the schema's tasklist description referencing list-tasklists, but that is not in the tool description itself.

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