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

With no annotations, the description carries the behavioral disclosure burden. It discloses durability ('One durable task'), the need to poll the returned task_ref, recovery through operation_ref, and token-based recovery with the same unexpired token. It doesn't spell out full side effects, but this is meaningful transparency for a confirm action.

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?

Three sentences with no filler: the first gives purpose, the second covers execution behavior, and the third explains recovery. Every sentence earns its place.

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 one required parameter, no output schema, and no annotations, the description adequately covers the confirm-and-recover lifecycle via task_ref, operation_ref, and token expiry/reuse. It could explicitly identify the prior prepare step or token source, but an agent has enough information to invoke and monitor the task.

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 coverage is 0%, so the description must carry parameter meaning. It adds that confirm_token must be 'the same unexpired token' and that replacement plans are never used, which clarifies reusability and expiry. It still doesn't specify where the token comes from or its format, leaving a moderate gap.

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 first sentence names a specific verb (Confirm) and resource ('one prepared TikTok structural clone') and qualifies it with 'after explicit user approval.' This clearly distinguishes the tool from its deny and prepare siblings.

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 gives a concrete condition for use: confirm only after explicit user approval, and only for a prepared clone. It does not explicitly name the deny alternative or state when not to use it, but the usage context is clear enough.

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