play_ab_wavs_tool

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does reveal meaningful behavior: two WAVs are played back-to-back with a short silence gap as a single concat, which is useful. However, the dry_run parameter's behavioral effect (whether anything is actually played) is not disclosed, and missing-file/error behavior is unaddressed.

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?

A single well-formed sentence with no filler. The key facts — two WAVs, back-to-back, silence gap, one concat — are front-loaded and every word earns its place. This is appropriately sized for the information it conveys.

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 tool with 5 parameters, 3 required, 0% schema coverage, and no annotations, one sentence is insufficient. The output schema covers return values, but the semantics of project_path and dry_run are left completely undefined, and there is no routing guidance relative to play_ab_tool. An agent could call this incorrectly by misunderstanding dry_run or project_path.

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 description must compensate. It partially does: 'two existing WAVs' clarifies wav_a and wav_b are file paths, and 'short silence gap' maps to gap_sec. But project_path and dry_run receive no semantic explanation, leaving the agent to guess what project_path refers to and what dry-run mode does.

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 states a specific verb ('Play') and a specific resource ('two existing WAVs') with the behavioral detail of a back-to-back silence-gapped concat, making the core action clear. However, it does not distinguish itself from the closely-named sibling play_ab_tool, so an agent cannot tell which of the two AB-playback tools to pick without further investigation.

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 offers no guidance on when to use this tool versus alternatives. Notably, sibling play_ab_tool exists and is likely the same AB-playback concept, yet no condition (e.g., 'use when you have file paths to WAVs') is given to route the agent. Context must be inferred entirely from the tool name.

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