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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety profile is partially covered. The description adds that the tool operates on task-board lists and can rename or move existing ones, but it does not explain side effects such as what happens to tasks in a moved list or whether the operation is reversible. With annotations present, this is an adequate but limited disclosure.

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 definition is a single compact sentence with no filler, and the primary actions are front-loaded. Every word contributes to conveying the tool's scope.

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 six-parameter tool with no required parameters and two distinct modes (create new list vs. rename/move existing), the description is too sparse. It does not explain which parameters apply to which mode, does not address the lack of output schema, and leaves important invocation details to inference.

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?

With six parameters and only 50% schema description coverage, the description should clarify parameter roles, especially how list_id distinguishes rename/move from create, and how class, class_id, and personal select the target board. It provides none of this, so the agent must infer the create-vs-update parameter mapping from the schema alone, where several parameters are 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?

The description states a concrete resource (task board list/column) and concrete actions (create, rename, move), so the agent can distinguish it from siblings such as delete_task_list or save_task_label. It does not explicitly disambiguate from broader board tools like create_board or update_board, so it is clear but not sibling-differentiated to the highest degree.

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 phrase 'Neue Liste ... oder bestehende umbenennen/verschieben' implies the two usage modes: creating a new list or modifying an existing one. However, there is no explicit guidance on when to choose this tool over create_board/update_board, nor any prerequisites or exclusions.

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