transport_cancel_auto_advance

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

With no annotations present, the description must fully disclose behavioral traits. It only states the action (cancel) without explaining side effects, reversibility, required permissions, or what happens to auto-advance timers. The minimal description fails to provide sufficient transparency.

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 sentence that is perfectly concise and front-loaded with the verb. Every word serves a purpose, and there is no superfluous information. It achieves efficiency without sacrificing clarity.

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?

The tool is simple (one parameter, no output schema), but the description lacks context about the outcome of cancellation (e.g., state changes, return value, persistence). While adequate for basic understanding, it is incomplete in terms of behavioral context for an agent.

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 already describes the 'layer' parameter with 100% coverage. The description adds no extra meaning beyond the schema, so baseline score of 3 applies. No additional semantic clarification is provided.

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 verb 'cancel' and the resource 'auto-advance' with scope limited to 'presentation or announcement layer'. This straightforwardly identifies the tool's function and distinguishes it from siblings like 'transport_pause' or 'transport_get_auto_advance'.

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 guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, conditions for cancellation, or comparison with similar tools like 'transport_pause' or 'announcement_timeline_operation'. This leaves 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.
