create_audio_tool

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Generate a WAV audio test fixture' without explaining file creation side effects, overwrite behavior, output directory handling, or what happens on error. The examples hint at parameters but not operational behavior.

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 extremely concise—two sentences total—with the second sentence providing illustrative examples without wasteful text. It is front-loaded with the core purpose and uses examples efficiently.

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?

Given the tool has 8 parameters, no annotations, and 0% schema description coverage, a two-sentence description is not enough. It fails to mention key parameters like output_directory, overwrite, channels, and sample_rate, leaving the agent to guess at their meaning and interaction. The examples cover only two scenarios.

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 for 8 parameters. It only illustrates silence and tone_hz via examples, leaving channels, sample_rate, output_directory, overwrite, filename, and duration_seconds without semantic explanation beyond their names and defaults. This is insufficient for a tool with many tunable parameters.

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 'Generate a WAV audio test fixture,' specifying the verb, resource, and format. The examples ('30-second silent WAV, 5-second 440 Hz tone') further clarify scope and distinguish it from sibling file-creation tools like create_image_tool or create_pdf_tool.

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 provides examples of typical usage ('30-second silent WAV, 5-second 440 Hz tone') but does not explicitly state when to use this tool versus alternatives, nor any exclusions or prerequisites. Context is implied by the tool name and sibling set, but no direct guidance is given on tool selection.

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