rename_task_list

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

The annotations already declare non-destructive and idempotent behavior, and 'preserving its tasks' reinforces the non-destructive nature but adds limited extra disclosure. It does not describe permissions, error cases, or whether a title collision is allowed, so a 3 is appropriate given the annotation coverage.

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 zero waste, and the key scoping constraint ('by exact ID') is front-loaded. Every part of the sentence contributes to understanding the operation.

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 the description need not explain return values; annotations cover safety and idempotency; and the schema documents the critical ID parameter. For a simple two-parameter rename tool this is largely sufficient, though it could mention title uniqueness or validation behavior.

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 schema documents task_list_id with an exact-ID warning, and the description's 'by exact ID' echoes that; the title parameter is self-evident from its name and schema constraints. With 50% schema description coverage, the description does not add constraints or syntax beyond what the schema provides, so this meets the baseline 3.

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 names the specific verb 'Rename' and resource 'task list', with additional scope from 'by exact ID' and 'preserving its tasks'. This makes it clearly distinguishable from delete_task_list and from create/get/list siblings without needing to name them.

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?

There is no explicit when-to-use or when-not guidance. It does not name alternatives such as delete_task_list or create_task_list, and only implies that this operation is for renaming by ID rather than by name.

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