audio_sequence

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

No annotations are provided, so the description carries full burden. It mentions creating a layered track and returning success/output_path, but does not disclose whether output_path overwrites existing files, or any side effects like file system permissions. Basic transparency, but missing details.

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 relatively concise, using bullet points in Args. However, it repeats the first sentence 'Compose multiple audio events...' and 'Creates a layered audio track...' which is slightly redundant. Still efficient overall.

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 description covers the input parameters and return value in a way that is sufficient for understanding the tool's usage. Given the complexity (array of objects without a predefined schema), it provides enough context. Missing elements like error handling or file overwrite behavior are minor gaps.

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 0%, but the description compensates by detailing the structure of sequence items (type, at, duration, freq/frequency, name, volume, waveform) and explaining output_path. This adds significant meaning beyond the raw schema, though the schema's additionalProperties:true leaves some ambiguity.

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 composes multiple audio events into a timed sequence, using specific verbs like 'Compose' and 'Creates a layered audio track'. It distinguishes from siblings like 'audio_synthesize' (single sound generation) and 'audio_preset' (preset sounds) by emphasizing the combination of multiple events.

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 implies the tool is for creating timed sequences from multiple events, but does not explicitly state when to use it over alternatives or provide exclusions. No guidance on prerequisites or comparison with sibling tools is given.

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