dspy-cli 0.1.4

A CLI tool for creating and serving DSPy projects

dspy-cli

A command-line interface tool for creating and serving DSPy projects, inspired by Ruby on Rails.

Installation

uv add dspy-cli

Installing for Development/Testing

If you're testing or developing dspy-cli itself:

# Clone or navigate to the dspy-cli repository
cd /path/to/dspy-cli

# Sync dependencies
uv sync --extra dev

# Now the dspy-cli command is available
dspy-cli --help

Quick Start

Create a new DSPy project

dspy-cli new my-project
cd my-project

Create a project with a custom program name

dspy-cli new my-project -p custom_program

Create a project with a custom signature

dspy-cli new blog-tagger -s "post -> tags: list[str]"

Serve your DSPy programs as an API

dspy-cli serve --port 8000 --host 0.0.0.0

Features

• Project scaffolding: Generate a complete DSPy project structure with boilerplate code
• Code generation: Quickly scaffold new DSPy programs with signatures and modules using Rails-style generators
• Convention over configuration: Organized directory structure for modules, signatures, optimizers, and metrics
• HTTP API server: Automatically serve your DSPy programs as REST endpoints
• Flexible configuration: YAML-based model configuration with environment variable support
• Logging: Request logging to both STDOUT and per-module log files

Project Structure

When you create a new project, dspy-cli generates the following structure:

my-project/
├── pyproject.toml
├── dspy.config.yaml       # Model registry and configuration
├── .env                   # API keys and secrets

Commands

new

Create a new DSPy project with boilerplate structure.

dspy-cli new [PROJECT_NAME] [OPTIONS]

Options:

• -p, --program-name TEXT: Name of the initial program (default: converts project name)
• -s, --signature TEXT: Inline signature string (e.g., "question -> answer" or "post -> tags: list[str]")

Examples:

# Basic project
dspy-cli new my-project

# With custom program name
dspy-cli new my-project -p custom_program

# With custom signature
dspy-cli new blog-tagger -s "post -> tags: list[str]"

# With both program name and signature
dspy-cli new analyzer -p text_analyzer -s "text, context: list[str] -> summary, sentiment: bool"

generate (alias: g)

Generate new components in an existing DSPy project.

dspy-cli generate scaffold PROGRAM_NAME [OPTIONS]
dspy-cli g scaffold PROGRAM_NAME [OPTIONS]

Options:

• -m, --module TEXT: DSPy module type to use (default: Predict)
  • Available: Predict, ChainOfThought (or CoT), ProgramOfThought (or PoT), ReAct, MultiChainComparison, Refine
• -s, --signature TEXT: Inline signature string (e.g., "question -> answer")

Examples:

# Basic scaffold with default Predict module
dspy-cli g scaffold categorizer

# Scaffold with ChainOfThought
dspy-cli g scaffold categorizer -m CoT

# Scaffold with custom signature
dspy-cli g scaffold qa -m CoT -s "question -> answer"

# Complex signature with types
dspy-cli g scaffold search -s "query, context: list[str] -> answer, confidence: float"

serve

Start an HTTP API server that exposes your DSPy programs.

dspy-cli serve [OPTIONS]

Options:

• --port INTEGER: Port to run the server on (default: 8000)
• --host TEXT: Host to bind to (default: 0.0.0.0)

Endpoints:

• GET /programs: List all discovered programs with their schemas
• POST /{program}: Execute a program with JSON payload

Configuration

dspy.config.yaml

Configure your language models and routing:

models:
  default: openai:gpt-4o-mini
  registry:
    openai:gpt-4o-mini:
      model: openai/gpt-4o-mini
      env: OPENAI_API_KEY
      max_tokens: 16000
      temperature: 1.0
      model_type: chat
    anthropic:sonnet-4-5:
      model: anthropic/claude-sonnet-4-5
      env: ANTHROPIC_API_KEY
      model_type: chat

# Optional: per-program model overrides
program_models:
  MySpecialProgram: anthropic:sonnet-4-5

.env

Store your API keys and secrets:

OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...
