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

With no annotations, the description carries the burden of explaining behavior. It states the action (suspends audio processing), the purpose (save CPU), and the reversibility (wake() to resume). It does not mention potential side effects on playback or idempotency, but covers the core behavior sufficiently.

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 two concise sentences, front-loaded with the action and followed by usage guidance and resumption instruction. Every sentence adds value with no redundancy or filler.

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?

For a simple no-parameter tool with an output schema, the description fully covers the tool's purpose, when to use it, and how to reverse it. It gives an agent enough information to select and invoke the tool correctly without ambiguity.

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 has zero properties, so there are no parameters to explain. The description correctly focuses on behavior and usage rather than parameter details, earning the baseline score of 4 for a zero-parameter tool.

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 uses a specific verb phrase 'Put the audio engine to sleep' and identifies the resource ('audio engine') and the effect ('suspends audio processing to save CPU'). This clearly distinguishes it from sibling tools like engine_wake, engine_panic, and start_engine.

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 gives explicit usage context: 'Useful when doing non-audio operations (project editing, box manipulation) and the engine isn't needed.' It also names the complementary action with 'Use wake() to resume,' directing the agent to the correct sibling for the opposite operation.

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