Below is a complete, standalone Product Requirements Document (PRD) for ToneForge CLI, written to integrate cleanly with the ToneForge ecosystem and support automation, CI/CD, and large‑scale procedural audio workflows.

🖥️ ToneForge CLI

Product Requirements Document (PRD)

1. Product Overview

Product Name

ToneForge CLI

Description

ToneForge CLI is the command‑line interface for the ToneForge ecosystem. It provides a scriptable, automatable, and deterministic way to generate, analyze, classify, explore, stack, export, and manage procedural sound effects at scale.

ToneForge CLI is designed for:

  • build pipelines
  • CI/CD systems
  • batch asset generation
  • headless environments
  • power users and technical sound designers

It is the primary automation surface for ToneForge.

2. Role in the ToneForge Ecosystem

ToneForge CLI spans the entire lifecycle:

Author → Generate → Stack → Analyze → Classify → Explore → Store → Integrate → Ship

Its purpose is to:

  • expose all ToneForge capabilities non‑interactively
  • enable reproducible builds
  • support large‑scale sound generation
  • integrate with existing toolchains
  • automate placeholder asset generation

3. Design Goals

Primary Goals

  • Deterministic, repeatable execution
  • Script‑friendly interface
  • Clear, composable commands
  • JSON‑based configuration
  • CI‑safe operation
  • Cross‑platform support

Non‑Goals

  • Interactive sound editing
  • GUI replacement
  • Real‑time audio playback
  • AI model training

4. Core Concepts

4.1 Command Model

ToneForge CLI uses a verb‑first command structure:

toneforge <command> [options]

Commands are:

  • composable
  • idempotent where possible
  • explicit in side effects

4.2 Configuration

All commands support:

  • inline flags
  • JSON config files
  • environment variables

Configuration precedence:

  1. CLI flags
  2. Config file
  3. Environment variables
  4. Defaults

5. Core Commands

5.1 generate

Generates procedural or hybrid sound effects.

toneforge generate \
  --recipe footstep \
  --variant gravel \
  --count 1000 \
  --seed-range 1000:2000

Options

  • --recipe
  • --variant
  • --count
  • --seed
  • --seed-range
  • --duration
  • --samples

5.2 stack

Renders layered sound events using ToneForge Stack.

toneforge stack \
  --preset explosion_heavy.json \
  --export wav

5.3 analyze

Runs ToneForge Analyze on audio assets.

toneforge analyze \
  --input ./renders \
  --output ./analysis

5.4 classify

Runs ToneForge Classify on analyzed sounds.

toneforge classify \
  --analysis ./analysis \
  --output ./classification

5.5 explore

Performs procedural sound exploration.

toneforge explore \
  --recipe creature \
  --seed-range 0:10000 \
  --keep-top 200

5.6 library

Manages ToneForge Library assets.

toneforge library list --category ui
toneforge library export --format wav

5.7 compile

Compiles a curated library into production assets.

toneforge compile \
  --category footsteps \
  --format wav \
  --validate

6. Batch & Pipeline Support

ToneForge CLI is designed for large‑scale batch execution.

Features

  • parallel processing
  • resumable jobs
  • progress reporting
  • partial failure recovery

7. Determinism & Reproducibility

ToneForge CLI guarantees:

  • same inputs → same outputs
  • explicit version locking
  • deterministic seed handling
  • reproducible builds across machines

Each run records:

  • ToneForge version
  • command invocation
  • configuration hash
  • timestamps

8. Output Artifacts

Depending on command, outputs may include:

  • WAV files
  • JSON presets
  • analysis metadata
  • classification metadata
  • logs and reports

All outputs are:

  • structured
  • machine‑readable
  • versioned

9. Error Handling & Logging

Error Handling

  • clear exit codes
  • descriptive error messages
  • non‑fatal warnings where possible

Logging

  • human‑readable console output
  • optional JSON logs for CI
  • verbosity levels

10. CI/CD Integration

ToneForge CLI is safe for:

  • headless execution
  • sandboxed environments
  • automated builds

Supports:

  • fail‑fast validation
  • artifact caching
  • incremental builds

11. Security & Stability

  • No dynamic code execution
  • Explicit file access
  • Predictable resource usage
  • Safe for shared build agents

12. Performance Targets

  • Fast startup time
  • Efficient batch processing
  • Scales to tens of thousands of sounds
  • Minimal memory overhead

13. Extensibility

ToneForge CLI supports:

  • plugin commands
  • custom recipes
  • external integrations
  • future module expansion

14. Documentation & Help

Built‑in help system:

toneforge help
toneforge generate --help

Includes:

  • command descriptions
  • option explanations
  • usage examples

15. Why ToneForge CLI Matters

Without a CLI:

  • procedural audio cannot scale
  • automation breaks down
  • reproducibility is fragile

ToneForge CLI turns ToneForge into a production‑grade audio pipeline, enabling:

  • massive asset generation
  • deterministic builds
  • seamless integration into modern workflows

16. Summary

ToneForge CLI is the automation backbone of the ToneForge ecosystem.
It exposes every major capability through a clean, scriptable interface—making procedural audio generation reliable, scalable, and production‑ready.

If you want next, the natural follow‑ups are:

  • a CLI command reference spec
  • CI pipeline examples
  • or a plugin architecture design
