get_clip_volume

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

Annotations already declare readOnlyHint=true and idempotentHint=true, lowering the bar. The description adds useful context about silent clamping and the Amplify automation limitation, which goes beyond the annotations. However, it does not describe return value format or error behavior, which would be more transparent given the lack of output schema.

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 sentences, front-loads the primary purpose, and includes a pragmatic usage tip plus a limitation without any filler. 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?

For a simple one-parameter read tool with strong annotations, the description is nearly complete. It states the unit (dB), the verification use case, and a key limitation. However, it lacks explicit mention of return type (e.g., number) or possible null/error cases, but the lack of output schema makes these less critical.

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 description coverage is 100% for node_id with 'Node ID of the audio clip', so the schema carries the semantic weight. The description implies the clip is audio but adds no additional parameter-level meaning beyond what the schema already provides.

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 reads an audio clip's Volume > Level in dB with a specific verb 'Read' and resource. It distinguishes itself from siblings like set_clip_volume by focusing on verification and from broader getters by specifying the exact property.

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 explicitly says 'Use this to verify a level actually applied - setValue() clamps silently', providing a clear when-to-use scenario. It also states an exclusion with 'Does not report Essential Sound Amplify automation', giving a when-not-to-use condition.

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