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

The description goes beyond the readOnlyHint/destructiveHint annotations by explaining the internal storage location (TD root op), the advisory mechanism, and the concrete side effect (suppresses auto preview captures). It also clarifies what it does not do, adding valuable context.

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 compact and well-organized: a clear opening sentence, technical details in the middle, and a practical call-to-action at the end. Every sentence adds value without redundancy.

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 the tool's simplicity (one boolean parameter, no output schema), the description is fully complete. It covers the purpose, mechanism, side effects, exclusions, and usage lifecycle, leaving no critical questions unanswered.

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 input schema already provides 100% coverage for the single boolean parameter, and the description reinforces its meaning with real-world usage ('enabled=false after the show'). The parameter description in the schema even explains the mechanism and limitations, exceeding baseline expectations.

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 toggles perform mode, a specific advisory flag used before live shows. It distinguishes this from sibling tools like get_td_performance or optimize_performance by focusing on the single switch artists flip before going live.

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?

Explicitly states when to use it ('before going live', 'after the show') and provides an advisory exclusion ('does not stop the TD timeline or kill audio/video processing'). This gives clear guidance on appropriate contexts vs. alternatives.

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