label_delete_audio_at

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

With no annotations, the description carries the full disclosure burden. It states the destructive action and the 'closing the gap' consequence, but it never addresses whether the deletion is permanent or undoable, whether the label itself remains, or what happens on a missing key or empty region. For an annotation-free destructive audio operation, this is a significant transparency gap.

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 definition is minimal and well-ordered: a one-line behavior summary up front, followed by a tight Args block. There is no filler, and the parameter documentation is placed exactly where the reader needs it.

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 one-parameter tool with no output schema, the description covers the essential invocation: what it performs and how to build the key. However, it omits execution-critical context — reversibility, the fate of the label, invalid-key behavior — that an agent should know before issuing a destructive command. Adequate for calling it, incomplete for confident autonomous use.

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%, so the schema's 'key' property carries no meaning. The description compensates fully by specifying the exact format ('trackId:itemId') and the source (label_list). This makes the single parameter actionable on its own; only a concrete example would raise it to a 5.

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 names a specific verb and resource — 'Delete the audio under a single label' — plus a distinctive outcome, 'closing the gap,' which implies ripple-delete semantics. This implicitly separates it from siblings like label_remove or label_delete_regions that act on labels rather than the audio beneath them. Because the sibling differentiation is implicit rather than explicit, it stops short of a 5.

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 when-to-use guidance is given relative to the many nearby label tools (label_delete_regions, label_remove, edit_delete), and no exclusions or alternatives are named. The only hint, '(from label_list),' tells the agent where to get the key, not when this tool is the right choice. Usage must be inferred from the name and sibling list.

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