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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds two behavioral facts beyond annotations: deletion is permanent and occurs after approval in AlphaWeb. It still omits idempotency behavior and what happens if the schedule is referenced elsewhere.

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 front-loaded sentence with no wasted words. Its brevity is efficient, though for a destructive tool with three undocumented required parameters it could afford one more clarifying clause.

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 a destructive mutation, no output schema, and 100% of parameters lacking schema descriptions, the description is too thin. It covers permanence and an approval gate but leaves critical operational context, especially idempotency_key semantics and workspace requirements, unaddressed.

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% and there are three required parameters, so the description carries the full burden. It gives no meaning for workspace, schedule (beyond the resource name), or idempotency_key. An agent must infer all parameter semantics from bare names and formats.

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 verb and resource: "Permanently delete a hosted teammate schedule." It adds useful scope details (hosted teammate, permanence, AlphaWeb context) and is clearly distinct from the only sibling schedules_save. It does not explicitly name alternatives, but the purpose is unambiguous.

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?

It implies when to use the tool by noting deletion happens "after approval in AlphaWeb," which is a useful prerequisite. However, it does not state when not to use it, what approval means operationally, or compare against alternatives such as schedules_save or leaving a schedule inactive.

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