generate_dtmf

Generate telephone dual-tone multi-frequency (DTMF) tones for call simulation or testing, with adjustable sequence, amplitude, duty cycle, and duration.

Instructions

Generate DTMF (telephone) tones.

Args: sequence: DTMF characters (0-9, A-D, *, #). Default: "0123456789" duty_cycle: Tone vs silence ratio percentage (0-100). Default: 55 amplitude: Amplitude (0-1). Default: 0.8 duration: Total duration in seconds. Default: 1.0

Behavior2/5

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

No annotations provided; description lacks behavioral details like whether generation is nondestructive or affects project state. Only lists parameters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One-line summary followed by a parameter list. Efficient and well-organized, though the parameter formatting could be slightly more compact.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema and description omits return value or effect on project. For a generation tool, unclear if it creates a track or returns data.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Description adds full parameter explanations with defaults, valid ranges, and format for sequence, duty_cycle, amplitude, and duration. Schema has 0% coverage, so description carries the entire burden.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clear verb 'Generate' and resource 'DTMF (telephone) tones'. Distinguishes from sibling tools like generate_tone, generate_noise, etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives. Only a parameter list, no context on when DTMF is appropriate.

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