**Multi-provider LLM support • Offline-first • Session management • Tool execution**

askGPT is a powerful command-line interface for autonomous AI agents that can perform complex tasks including file operations, code analysis, and system commands. With offline-first defaults, askGPT works seamlessly with local models (Ollama) and cloud providers (OpenAI, Anthropic).

## What is askGPT?

askGPT is a CLI tool that provides autonomous AI agents with file system capabilities, session persistence, and multi-provider LLM support. By default, askGPT uses local models (via Ollama) for offline-first usage, while still supporting cloud providers when needed.

### Why askGPT?

- **🌐 Offline-First**: Defaults to local Ollama models - no API keys required
- **⚡ Multi-Provider**: Supports OpenAI, Anthropic, Ollama, and custom endpoints
- **🔐 Enterprise Security**: Fine-grained permissions, path restrictions, read-only mode
- **💬 Interactive Mode**: Rich terminal UI with session management
- **🎯 Commands & Agents**: Extensible markdown-based commands and agent profiles
- **🧠 Agent Skills**: Modular, auto-triggered capabilities
- **💰 Cost Tracking**: Token usage and cost estimation
- **📦 Quick Setup**: Install in 5 minutes

## Quick Start

### Install in 5 Minutes

```bash
# macOS/Linux
curl -fsSL https://raw.githubusercontent.com/meirm/askGPT/main/install.sh | bash

# Or install from local repository
./install.sh --local
```

### Try It Out

```bash
# Interactive mode with rich terminal UI (default when no arguments)
askgpt

# Quick prompt (defaults to local Ollama model)
askgpt -p "Create a hello world script"

# Use specific local model
askgpt -p "Analyze this codebase" --model gpt-oss:20b --provider ollama

# Use cloud provider (requires API key)
askgpt -p "Write a function" --model gpt-5-mini --provider openai

# Safe exploration with read-only mode
askgpt -p "Analyze this codebase" --read-only

# List available models
askgpt list-models --provider ollama

# Continue conversation with session persistence
askgpt -p "Add error handling to that function" --continue

# Use custom commands
askgpt -p '/analyze "Review this code for security issues"'

# Use specialized agents
askgpt -p "Explain this code" --agent analyst

# Skills automatically trigger based on your prompt
askgpt -p "Generate a README for this project"
askgpt -p "Check code formatting and style"
askgpt -p "Write release notes for version 1.0"
```

## Core Features

### 🌐 Offline-First Design

askGPT defaults to using local Ollama models for zero external dependencies:

```bash
# Works offline with local models (no API key needed)
askgpt -p "Your task here"
# Defaults to: provider=ollama, model=gpt-oss:20b

# Switch to cloud providers when needed
askgpt -p "Task" --provider openai --model gpt-5-mini
```

### 🤖 Multi-Provider Support

**Use ANY model from ANY provider** - no hardcoded restrictions:

| Provider | Example Models | Configuration |
|----------|---------------|---------------|
| **Ollama** (default) | gpt-oss:20b, llama3.2:latest, mistral | No API key needed |
| **OpenAI** | GPT-5, GPT-4o | API key required |
| **Anthropic** | Claude models | API key required |
| **Custom** | Your own endpoints | Fully configurable |

```bash
# Local models (offline-first)
askgpt -p "Task" --provider ollama --model gpt-oss:20b
askgpt -p "Task" --model llama3.2:latest  # provider defaults to ollama

# Cloud models
askgpt -p "Task" --provider openai --model gpt-5
askgpt -p "Task" --provider anthropic --model claude-3-haiku-20240307
```

### 🔐 Enterprise Security

**Fine-Grained Permissions**

```bash
# Read-only mode for safe exploration
askgpt -p "Audit the codebase for vulnerabilities" --read-only

# Limit tool calls for safety
askgpt -p "Analyze project" --max-tool-calls 10

# Unlimited calls for complex operations
askgpt -p "Refactor entire codebase" --unlimited-tool-calls
```

### 💬 Session Management

**Persistent Conversations**

```bash
# Start a project
askgpt -p "Create a Flask API" --new
# Returns: session_abc123

# Continue with context (agent remembers everything)
askgpt -p "Add user authentication" --continue
askgpt -p "Add input validation" --continue

# Or use specific session
askgpt -p "Add logging" --session session_abc123
```

**Session Features**
- Conversation history preservation
- Token usage tracking per session
- Model/provider settings persistence
- Multi-project management
- Cost tracking and analytics

### 🎯 Commands & Agents

```bash
# Create custom command templates
askgpt commands create code-review
askgpt -p '/code-review "src/auth"'

# Use specialized agents
askgpt -p "Analyze code" --agent analyst
askgpt -p "Write tests" --agent coder
askgpt -p "Generate ideas" --agent creative

# List available commands and agents
askgpt commands list
askgpt agents list
```

### 🧠 Agent Skills System

**Modular, auto-triggered capabilities** - Skills automatically activate when relevant:

```bash
# List all available skills
askgpt skills list

# Show details about a specific skill
askgpt skills show readme-generator

# Skills automatically trigger when you ask relevant questions:
askgpt -p "Generate a README for this project"
# → Automatically uses readme-generator skill

askgpt -p "Check code formatting across all Python files"
# → Automatically uses code-formatting-checker skill
```
