Cancel a scheduled TikTok post

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

With no annotations, the description carries the full burden. It reveals the mechanism (deleting the held video) but omits irreversibility, prerequisites, or error conditions, leaving the agent uncertain about the side effects of cancellation.

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 one concise sentence that front-loads the core action. While very short, it avoids waste and is easy to parse, though it could have been expanded with meaningful details.

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 no annotations, no output schema, and an undocumented operation_id, the description leaves key gaps: what happens on success, how to obtain operation_id, and whether any prerequisites exist. This is incomplete for a destructive action.

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 schema documents account_id but operation_id is only shown as a required string with no meaning. The description adds no context for either parameter, failing to compensate for the 50% schema coverage 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 description clearly states the tool cancels a native scheduled post by deleting its held video. The verb 'cancel' and resource 'scheduled post' are specific and distinguish it from other tools like tiktok_post or tiktok_delete.

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?

No explicit when-to-use guidance or alternative tools are mentioned. It does not clarify when to choose this over tiktok_delete or how to obtain the operation_id, leaving the agent to infer usage context.

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