# CmdForge

**A lightweight personal tool builder for AI-powered CLI commands.**

Turn any AI model into a Unix-style pipe command. Build once, use forever.

```bash
# Fix grammar in any file
echo "teh cat sat on teh mat" | fix-grammar
# Output: The cat sat on the mat

# Explain errors instantly
cat error.log | explain-error

# Generate commit messages
git diff --staged | commit-msg

# Extract data as validated JSON
echo "Price $49.99, SKU ABC-123" | json-extract --fields "price, sku"
# Output: {"price": 49.99, "sku": "ABC-123"}
```

## Why CmdForge?

- **Unix Philosophy** - Tools that do one thing well, composable with pipes
- **Provider Agnostic** - Works with Claude, GPT, Gemini, DeepSeek, local models
- **No Lock-in** - Your tools are YAML files, your prompts are yours
- **Multi-step Pipelines** - Chain AI prompts with Python code for validation
- **Meta-tools** - Tools can call other tools for powerful composition
- **12+ Providers Profiled** - We tested them so you don't have to

## Try It Now (60 seconds)

See CmdForge in action without installing anything on your system:

```bash
# Pull the container
docker pull gitea.brrd.tech/rob/cmdforge:latest

# Run it
docker run -it --rm gitea.brrd.tech/rob/cmdforge bash

# Inside the container - install OpenCode (includes free AI models)
cmdforge providers install   # Select option 4, then 'y'
source ~/.bashrc

# Try it! This explains the README using the free Big Pickle model
cat README.md | eli5
```

That's it - you just used AI to explain itself. The `eli5` tool uses a free model by default, no sign-up required.

## Quick Start (Native Install)

For regular use, install natively:

```bash
# Clone and install
git clone https://gitea.brrd.tech/rob/CmdForge.git
cd CmdForge
pip install -e .

# Ensure ~/.local/bin is in PATH
export PATH="$HOME/.local/bin:$PATH"

# Install an AI provider (interactive guide)
cmdforge providers install

# Launch the GUI
cmdforge

# Or create your first tool via CLI
cmdforge create summarize
```

## Installation

### Native Install

```bash
git clone https://gitea.brrd.tech/rob/CmdForge.git
cd CmdForge
pip install -e .
```

### With Development Dependencies

```bash
git clone https://gitea.brrd.tech/rob/CmdForge.git
cd CmdForge
pip install -e ".[dev]"
```

### Requirements

- Python 3.10+
- At least one AI CLI tool installed (see [Provider Setup](docs/PROVIDERS.md))
- PySide6 (included automatically - requires display server on Linux)

### Post-Install

Add to your `~/.bashrc` or `~/.zshrc`:

```bash
export PATH="$HOME/.local/bin:$PATH"
```

Then refresh wrapper scripts:

```bash
cmdforge refresh
```

## Usage

### GUI Mode (Recommended for Beginners)

```bash
cmdforge
```

Opens the graphical interface where you can create and manage tools visually. Features include:
- **My Tools** - Browse, create, edit, and delete tools organized by category
- **Registry** - Search and install community tools from the CmdForge registry
- **Providers** - Manage AI provider configurations

### CLI Mode

```bash
cmdforge list              # List all tools
cmdforge create mytool     # Create new tool
cmdforge edit mytool       # Edit in $EDITOR
cmdforge delete mytool     # Delete tool
cmdforge run mytool        # Run a tool
cmdforge test mytool       # Test with mock provider
cmdforge check mytool      # Check dependencies (meta-tools)
cmdforge refresh           # Update executable wrappers
```

### Running Tools

Once created, tools work like any Unix command:

```bash
# Direct invocation
mytool -i input.txt -o output.txt

# Pipe input (most common)
cat file.txt | mytool

# With arguments
echo "hello" | translate --lang French

# Preview without calling AI
cat file.txt | mytool --dry-run

# Test with mock provider
cat file.txt | mytool --provider mock
```

### Composing Tools

CmdForge follows Unix philosophy: each tool does one thing well, and tools chain together for complex workflows.

```bash
# Chain CmdForge together
cat error.log | log-errors | summarize | translate --lang Spanish

# Code review pipeline: focus on changes, review, then summarize
git diff | diff-focus | review-code | tldr

# Extract data, convert format, analyze
cat report.pdf | json-extract --fields "revenue, costs, date" | json2csv | csv-insights

# Process text through multiple transformations
cat technical_doc.txt | simplify | fix-grammar | tone-shift --tone friendly

# Generate code, validate it, then explain what it does
echo "parse CSV and calculate averages" | code-validate | explain-code
```

**Mix with standard Unix tools:**

```bash
# Extract emails, deduplicate, count
cat inbox.txt | extract-emails | sort -u | wc -l

# Find errors in multiple logs, explain them
cat *.log | grep -i error | explain-error

# Generate changelog for specific author
git log --author="rob" --oneline | changelog > CHANGELOG.md

# Review only large files in a commit
git diff --stat | awk '$3 > 100 {print $1}' | xargs cat | review-code
```

**Build shell functions for common pipelines:**

```bash
# ~/.bashrc
quick-review() {
    git diff "$@" | diff-focus | review-code --focus "bugs and security" | tldr
}

translate-doc() {
    cat "$1" | summarize | translate --lang "$2"
}

# Usage: quick-review HEAD~3
# Usage: translate-doc manual.txt French
```

See [docs/PROVIDERS.md](docs/PROVIDERS.md) for setup instructions.

## Tool Anatomy

A tool is a YAML config file in `~/.cmdforge/<name>/config.yaml`:

```yaml
name: summarize
description: Condense documents to key points
category: Text  # Optional: Text, Developer, Data, or Other
arguments:
  - flag: --length
    variable: length
    default: "3-5 bullet points"
steps:
  - type: prompt
    prompt: |
      Summarize this text into {length}:

      {input}
    provider: opencode-pickle
    output_var: response
output: "{response}"
```

### Categories

Tools can be organized into categories for easier navigation in the UI:

| Category | Description |
|----------|-------------|
| `Text` | Text processing (summarize, translate, grammar) |
| `Developer` | Dev tools (explain-error, gen-tests, commit-msg) |
| `Data` | Data extraction and conversion (json-extract, csv) |
| `Other` | Default for uncategorized tools |

### Multi-Step Tools

Chain AI prompts with Python code for powerful workflows:

```yaml
name: json-extract
description: Extract data as validated JSON
steps:
  # Step 1: AI extracts data
  - type: prompt
    prompt: "Extract {fields} as JSON from: {input}"
    provider: opencode-deepseek
    output_var: raw_json

  # Step 2: Code validates JSON
  - type: code
    code: |
      import json
      try:
          parsed = json.loads(raw_json)
          validated = json.dumps(parsed, indent=2)
      except:
          validated = "ERROR: Invalid JSON"
    output_var: validated
output: "{validated}"
```

### Meta-Tools (Tools Calling Tools)

Tools can call other tools as steps, enabling powerful composition:

```yaml
name: summarize-and-translate
description: Summarize text then translate the summary
dependencies:
  - official/summarize
  - official/translate
steps:
  - type: tool
    tool: official/summarize
    input: "{input}"
    args:
      max_words: "100"
    output_var: summary

  - type: tool
    tool: official/translate
    input: "{summary}"
    args:
      target_language: "{language}"
    output_var: translated
output: "{translated}"
```

Check dependencies before running: `cmdforge check my-meta-tool`

See [docs/META_TOOLS.md](docs/META_TOOLS.md) for full documentation.

### Variables

| Variable | Description |
|----------|-------------|
| `{input}` | The piped/file input |
| `{argname}` | Custom argument value |
| `{output_var}` | Output from previous step (prompt, code, or tool) |

## Shell Integration

## Multi-Step Tool Patterns

CmdForge supports powerful multi-step workflows combining AI and code:

### Code → AI
Extract or transform data with Python, then pass to AI:
```yaml
steps:
  - type: code
    code: |
      # Extract just the error lines
      errors = [l for l in input_text.split('\n') if 'error' in l.lower()]
      result = '\n'.join(errors[-10:])  # Last 10 errors
    output_var: errors
  - type: prompt
    prompt: "Explain these errors:\n{errors}"
    output_var: explanation
```

### AI → Code
Generate content with AI, then validate/process with Python:
```yaml
steps:
  - type: prompt
    prompt: "Generate Python code to: {input}"
    output_var: generated
  - type: code
    code: |
      import ast
      try:
          ast.parse(generated)  # Syntax check
          result = generated
      except SyntaxError as e:
          result = f"# Syntax Error: {e}\n{generated}"
    output_var: validated
```

## Philosophy

CmdForge is built on **Unix philosophy**:

1. **Do one thing well** - Each tool solves one problem. `summarize` summarizes. `translate` translates. No bloated mega-tools.

2. **Compose freely** - Tools read stdin, write stdout. Chain them: `cat doc.txt | summarize | translate --lang French`

3. **Text is the interface** - No proprietary formats. Pipe text in, get text out. Works with `grep`, `awk`, `sed`, and every other Unix tool.

4. **You own everything** - Tools are YAML files. Prompts are plain text. No vendor lock-in, no cloud dependency for your tool definitions.

5. **Swap parts freely** - Change AI providers per-tool or per-run. Today's best model might not be tomorrow's.

## Docker

### Pre-installed Container (Recommended)

Ready-to-use container with CmdForge and 27 example tools pre-installed:

```bash
# Build from source
docker build -f Dockerfile.ready -t cmdforge-ready .

# Run interactively
docker run -it --rm cmdforge-ready

# With persistent storage (keeps your tools between runs)
docker run -it --rm -v cmdforge-data:/home/user/.cmdforge cmdforge-ready
```

Inside the container, CmdForge is ready to use:
```bash
cmdforge list            # See 27 pre-installed tools
cmdforge                 # Launch the GUI (requires display)
cmdforge run summarize   # Run a tool
```

### Test Installation Container

Simulates a fresh computer for testing the installation process:

```bash
# Build the test container
docker build -f Dockerfile.test-install -t cmdforge-test-install .

# Run interactively
docker run -it --rm cmdforge-test-install

# Inside the container - run the installer
cd ~/CmdForge
./install.sh
```

### Interactive Installer

The `install.sh` script provides guided installation:

```bash
./install.sh              # Full interactive install
./install.sh --yes        # Non-interactive (accept defaults)
./install.sh --no-venv    # Install without virtual environment
./install.sh --no-examples # Skip installing example tools
```

Features:
- Creates virtual environment at `~/.cmdforge-venv`
- Configures PATH in your shell config (bash/zsh/fish)
- Optionally installs 27 example tools
- Works on macOS and Linux

### Legacy Container

The original docker-compose setup still works:

```bash
# Build the container
docker-compose build

# Run tests
docker-compose run --rm test

# Use the CLI
docker-compose run --rm cli cmdforge list

# Interactive shell
docker-compose run --rm shell
```

### Installing AI Providers in Docker

AI providers require browser-based authentication. You need display access for the browser to open.

**Using the pre-built container:**

```bash
# Allow Docker to access your display (Linux)
xhost +local:docker

# Run with display access and persistent storage
docker run -it --rm \
  -e DISPLAY=$DISPLAY \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -v cmdforge-data:/root/.cmdforge \
  --network host \
  gitea.brrd.tech/rob/cmdforge bash

# Inside the container:
cmdforge providers install
```

**Using docker-compose (build from source):**

```bash
xhost +local:docker
docker-compose run --rm setup

# Inside the container:
cmdforge providers install
```

**After installing a provider:**

```bash
# Test the provider works
cmdforge providers test claude
```

**Available Providers:**
| # | Provider | Cost | Notes |
|---|----------|------|-------|
| 1 | Claude | Pay-per-use | Anthropic account |
| 2 | Codex | Pay-per-use | OpenAI account |
| 3 | Gemini | Free tier | Google account |
| 4 | OpenCode | Free tier | Multiple models |
| 5 | Ollama | FREE | Local, no internet |
