Delete an event and all its tasks and completions permanently using a task list ID. Use this to remove an entire event when it is no longer needed; the action cannot be undone.
Delete an event (task list) and all its tasks and completions. This action is irreversible.

v3.12.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false. The description adds critical context: the cascade deletion of tasks/completions and irreversibility, which are not inferable from annotations alone. It doesn't contradict annotations.
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 sentences with no redundancy. Every phrase adds value: the resource, cascade scope, and irreversibility.
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?
Given the simple one-parameter schema and no output schema, the description adequately covers purpose, effect, and irreversible nature. It is complete enough for an agent to select and invoke correctly.
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 only parameter list_id is fully described in the schema as 'Task list (event) ID to delete' (100% coverage). The description does not add additional parameter-level details, so baseline 3 applies.
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 action (delete), the resource (event/task list), and the scope (all tasks and completions), distinguishing it from sibling delete tools for tasks and projects.
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 lacks explicit 'when to use' guidance or named alternatives, but the scope 'all its tasks and completions' implies a cascading delete, differentiating it from tascan_delete_task. It provides clear context but no exclusions or alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
