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

Annotations already flag destructiveHint:true, but the description adds important context that the deletion is permanent and that run history is also destroyed. This goes beyond what annotations alone convey and is consistent with idempotentHint:false.

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 short sentences with no wasted words. The core action is front-loaded, and the alternative usage is provided in a compact second sentence.

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 one-parameter destructive tool with annotations and an output schema, the description covers the essential facts: action, permanence, destroyed run history, and the pause alternative. The unexplained 'noticed' terminology and unstated id semantics are minor gaps, but the overall context is sufficient for safe invocation.

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 needed to explain the id parameter, but it never does. The agent must infer from the tool name that id identifies the scheduled task. The single obviously named parameter mitigates the gap, but the description still fails to explicitly add meaning beyond the schema.

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 specific action ('Permanently delete') on a specific resource ('one noticed agent task') and its run history, which clearly conveys what the tool does. It also distinguishes itself from update_scheduled_task by contrasting deletion with pausing. The unusual wording 'noticed agent task' is a minor blemish but does not obscure the core purpose.

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 explicitly says to use update_scheduled_task with enabled:false when the goal is to pause rather than delete. This gives the agent a clear routing rule between sibling tools and specifies when not to invoke this tool.

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