+# Configuring Ollama Provider in G3
+
+This guide shows you how to configure G3 to use Ollama as your LLM provider.
+
+## Quick Start
+
+### 1. Install Ollama
+
+```bash
+# Visit https://ollama.ai to download and install
+# Or use curl:
+curl https://ollama.ai/install.sh | sh
+```
+
+### 2. Pull a Model
+
+```bash
+ollama pull llama3.2
+# or any other model you prefer
+```
+
+### 3. Create Configuration File
+
+Copy the example configuration:
+
+```bash
+cp config.ollama.example.toml ~/.config/g3/config.toml
+```
+
+Or create it manually:
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2"
+```
+
+### 4. Run G3
+
+```bash
+g3
+# G3 will now use Ollama with llama3.2!
+```
+
+## Configuration Options
+
+### Basic Configuration
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2"
+```
+
+This is the minimal configuration needed. It uses all defaults:
+- Base URL: `http://localhost:11434`
+- Temperature: `0.7`
+- Max tokens: Not limited (uses model default)
+
+### Full Configuration
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2"
+base_url = "http://localhost:11434"
+max_tokens = 2048
+temperature = 0.7
+```
+
+### Custom Ollama Host
+
+If you're running Ollama on a different machine or port:
+
+```toml
+[providers.ollama]
+model = "llama3.2"
+base_url = "http://192.168.1.100:11434"
+```
+
+### Different Models
+
+You can use any Ollama model:
+
+```toml
+[providers.ollama]
+model = "qwen2.5:7b"  # Alibaba's Qwen model
+```
+
+```toml
+[providers.ollama]
+model = "mistral"  # Mistral AI
+```
+
+```toml
+[providers.ollama]
+model = "llama3.1:70b"  # Larger Llama model
+```
+
+## Multiple Provider Configuration
+
+You can configure multiple providers and switch between them:
+
+```toml
+[providers]
+default_provider = "ollama"  # Default for most operations
+
+# Ollama for local, fast responses
+[providers.ollama]
+model = "llama3.2:3b"
+temperature = 0.7
+
+# Databricks for more complex tasks
+[providers.databricks]
+host = "https://your-workspace.cloud.databricks.com"
+model = "databricks-claude-sonnet-4"
+max_tokens = 4096
+temperature = 0.1
+use_oauth = true
+```
+
+Then switch providers with:
+
+```bash
+g3 --provider databricks
+```
+
+## Autonomous Mode (Coach-Player)
+
+Use different providers for code review (coach) and implementation (player):
+
+```toml
+[providers]
+default_provider = "ollama"
+coach = "databricks"  # Use powerful cloud model for review
+player = "ollama"     # Use local model for implementation
+
+[providers.ollama]
+model = "qwen2.5:14b"  # Larger local model for coding
+
+[providers.databricks]
+host = "https://your-workspace.cloud.databricks.com"
+model = "databricks-claude-sonnet-4"
+use_oauth = true
+```
+
+This gives you the best of both worlds:
+- Fast local execution for coding tasks
+- Powerful cloud review for quality assurance
+
+## Recommended Models
+
+### For Coding Tasks
+
+| Model | Size | Speed | Quality | Notes |
+|-------|------|-------|---------|-------|
+| **qwen2.5:7b** | 7B | Fast | Excellent | Best balance for coding |
+| **llama3.2:3b** | 3B | Very Fast | Good | Great for quick tasks |
+| **llama3.1:8b** | 8B | Medium | Very Good | Solid all-rounder |
+| **mistral** | 7B | Fast | Good | Good for general use |
+
+### For Complex Tasks
+
+| Model | Size | Speed | Quality | Notes |
+|-------|------|-------|---------|-------|
+| **qwen2.5:14b** | 14B | Medium | Excellent | Best local model for coding |
+| **qwen2.5:32b** | 32B | Slow | Outstanding | If you have the resources |
+| **llama3.1:70b** | 70B | Very Slow | Outstanding | Requires significant RAM/GPU |
+
+## Temperature Settings
+
+Temperature controls randomness in responses:
+
+- **0.1-0.3**: Deterministic, good for code generation
+- **0.5-0.7**: Balanced, good for most tasks
+- **0.8-1.0**: Creative, good for brainstorming
+
+```toml
+[providers.ollama]
+model = "qwen2.5:7b"
+temperature = 0.2  # Focused code generation
+```
+
+## Max Tokens
+
+Control response length:
+
+```toml
+[providers.ollama]
+model = "llama3.2"
+max_tokens = 1024  # Shorter responses
+```
+
+```toml
+[providers.ollama]
+model = "qwen2.5:7b"
+max_tokens = 4096  # Longer, detailed responses
+```
+
+Leave it unset for model defaults (recommended).
+
+## Performance Tuning
+
+### GPU Acceleration
+
+Ollama automatically uses GPU if available. To check:
+
+```bash
+ollama ps
+```
+
+### Quantized Models
+
+For faster responses with less RAM:
+
+```toml
+[providers.ollama]
+model = "llama3.2:3b-q4_0"  # 4-bit quantization
+```
+
+Quantization options:
+- `q4_0`: 4-bit, fastest, lowest quality
+- `q5_0`: 5-bit, balanced
+- `q8_0`: 8-bit, slower, better quality
+
+### Multiple Models
+
+You can pull multiple models and switch easily:
+
+```bash
+ollama pull llama3.2:3b    # Fast for chat
+ollama pull qwen2.5:7b     # Better for code
+ollama pull mistral        # General purpose
+```
+
+Then change your config:
+
+```toml
+[providers.ollama]
+model = "qwen2.5:7b"  # Just change this line
+```
+
+## Troubleshooting
+
+### Ollama Not Running
+
+```bash
+# Check if Ollama is running
+curl http://localhost:11434/api/version
+
+# Start Ollama (macOS/Linux)
+ollama serve
+
+# Or just run a model (auto-starts)
+ollama run llama3.2
+```
+
+### Model Not Found
+
+```bash
+# List available models
+ollama list
+
+# Pull the model
+ollama pull llama3.2
+```
+
+### Slow Responses
+
+1. Use a smaller model:
+   ```toml
+   model = "llama3.2:1b"  # Smallest, fastest
+   ```
+
+2. Use quantized version:
+   ```toml
+   model = "llama3.2:3b-q4_0"
+   ```
+
+3. Reduce max_tokens:
+   ```toml
+   max_tokens = 512
+   ```
+
+### Out of Memory
+
+1. Switch to smaller model
+2. Use quantized version
+3. Close other applications
+4. Check GPU memory: `ollama ps`
+
+### Connection Refused
+
+Check base_url is correct:
+
+```toml
+[providers.ollama]
+model = "llama3.2"
+base_url = "http://localhost:11434"  # Default
+```
+
+For remote Ollama:
+
+```toml
+base_url = "http://your-server:11434"
+```
+
+## Complete Example Configs
+
+### Minimal Local Setup
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2"
+
+[agent]
+max_context_length = 8192
+enable_streaming = true
+timeout_seconds = 60
+```
+
+### Optimized for Coding
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "qwen2.5:7b"
+temperature = 0.2
+max_tokens = 2048
+
+[agent]
+max_context_length = 16384
+enable_streaming = true
+timeout_seconds = 120
+```
+
+### Fast Responses
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "llama3.2:3b-q4_0"
+temperature = 0.7
+max_tokens = 1024
+
+[agent]
+max_context_length = 4096
+enable_streaming = true
+timeout_seconds = 30
+```
+
+### High Quality (Requires Good Hardware)
+
+```toml
+[providers]
+default_provider = "ollama"
+
+[providers.ollama]
+model = "qwen2.5:32b"
+temperature = 0.3
+max_tokens = 4096
+
+[agent]
+max_context_length = 32768
+enable_streaming = true
+timeout_seconds = 300
+```
+
+### Hybrid (Local + Cloud)
+
+```toml
+[providers]
+default_provider = "ollama"
+coach = "databricks"
+player = "ollama"
+
+[providers.ollama]
+model = "qwen2.5:14b"
+temperature = 0.2
+
+[providers.databricks]
+host = "https://your-workspace.cloud.databricks.com"
+model = "databricks-claude-sonnet-4"
+use_oauth = true
+
+[agent]
+max_context_length = 16384
+enable_streaming = true
+timeout_seconds = 120
+```
+
+## Environment Variables
+
+You can override config with environment variables:
+
+```bash
+# Override model
+G3_PROVIDERS_OLLAMA_MODEL=qwen2.5:7b g3
+
+# Override base URL
+G3_PROVIDERS_OLLAMA_BASE_URL=http://192.168.1.100:11434 g3
+
+# Override default provider
+G3_PROVIDERS_DEFAULT_PROVIDER=ollama g3
+```
+
+## Best Practices
+
+1. **Start Small**: Begin with llama3.2:3b, scale up if needed
+2. **Use Quantization**: q4_0 or q5_0 for best speed/quality balance
+3. **Match Task to Model**: 
+   - Quick edits: 1B-3B models
+   - Code generation: 7B-14B models
+   - Complex refactoring: 14B-32B models
+4. **Temperature for Code**: Use 0.1-0.3 for deterministic output
+5. **Enable Streaming**: Always enable for better UX
+6. **Local First**: Use Ollama by default, cloud for special cases
+
+## Comparison with Other Providers
+
+| Feature | Ollama | Databricks | OpenAI | Anthropic |
+|---------|--------|------------|--------|-----------|
+| Cost | Free | Paid | Paid | Paid |
+| Privacy | Full | Medium | Low | Low |
+| Speed (small models) | Fast | Fast | Medium | Medium |
+| Speed (large models) | Slow | Fast | Fast | Fast |
+| Setup Complexity | Low | Medium | Low | Low |
+| Authentication | None | OAuth/Token | API Key | API Key |
+| Offline Support | Yes | No | No | No |
+| Tool Calling | Yes | Yes | Yes | Yes |
+

+
+### Custom Ollama Host
+
+```rust
+// Connect to remote Ollama instance
+let provider = OllamaProvider::new(
+    "llama3.2".to_string(),
+    Some("http://192.168.1.100:11434".to_string()),
+    None,
+    None,
+)?;
+```
+
+### Fetch Available Models
+
+```rust
+// Discover what models are available
+let models = provider.fetch_available_models().await?;
+println!("Available models:");
+for model in models {
+    println!("  - {}", model);
+}
+```
+
+## Supported Models
+
+The provider works with any Ollama model, including:
+
+- **llama3.2** (1B, 3B) - Meta's latest Llama models
+- **llama3.1** (8B, 70B, 405B) - Previous generation
+- **qwen2.5** (7B, 14B, 32B) - Alibaba's Qwen models  
+- **mistral** - Mistral AI models
+- **mixtral** - Mixture of experts model
+- **phi3** - Microsoft's Phi-3
+- **gemma2** - Google's Gemma 2
+
+## Configuration
+
+### Constructor Parameters
+
+```rust
+OllamaProvider::new(
+    model: String,           // Model name (e.g., "llama3.2")
+    base_url: Option<String>, // Ollama API URL (default: http://localhost:11434)
+    max_tokens: Option<u32>,  // Maximum tokens to generate (optional)
+    temperature: Option<f32>, // Sampling temperature (default: 0.7)
+)
+```
+
+### Request Options
+
+```rust
+CompletionRequest {
+    messages: Vec<Message>,      // Conversation history
+    max_tokens: Option<u32>,     // Override provider's max_tokens
+    temperature: Option<f32>,    // Override provider's temperature
+    stream: bool,                // Enable streaming responses
+    tools: Option<Vec<Tool>>,    // Tools for function calling
+}
+```

+## Comparison with Other Providers
+
+| Feature | Ollama | OpenAI | Anthropic | Databricks |
+|---------|--------|--------|-----------|------------|
+| Local Execution | ✅ | ❌ | ❌ | ❌ |
+| Authentication | None | API Key | API Key | OAuth/Token |
+| Tool Calling | ✅ | ✅ | ✅ | ✅ |
+| Streaming | ✅ | ✅ | ✅ | ✅ |
+| Cost | Free | Paid | Paid | Paid |
+| Privacy | High | Low | Low | Medium |
+
+## Implementation Details
+
+### API Endpoints
+
+- **Chat Completion**: `POST /api/chat`
+- **Model List**: `GET /api/tags`
+
+### Response Format
+
+Ollama uses a simple JSON-per-line streaming format:
+
+```json
+{"message":{"role":"assistant","content":"Hello"},"done":false}
+{"message":{"role":"assistant","content":" there"},"done":false}
+{"done":true,"prompt_eval_count":10,"eval_count":20}
+```
+
+### Tool Call Format
+
+Tool calls are returned in the message structure:
+
+```json
+{
+  "message": {
+    "role": "assistant",
+    "content": "",
+    "tool_calls": [
+      {
+        "function": {
+          "name": "get_weather",
+          "arguments": {"location": "Paris", "unit": "celsius"}
+        }
+      }
+    ]
+  },
+  "done": true
+}
+```
+
+## Troubleshooting
+
+### Connection Errors
+
+If you see connection errors, ensure Ollama is running:
+
+```bash
+# Check if Ollama is running
+curl http://localhost:11434/api/version
+
+# Start Ollama (if needed)
+ollama serve
+```
+
+### Model Not Found
+
+Pull the model first:
+
+```bash
+ollama pull llama3.2
+ollama list  # Check available models
+```
+
+### Performance Issues
+
+- Use smaller models (1B, 3B) for faster responses
+- Reduce `max_tokens` to limit generation length
+- Enable GPU acceleration if available
+- Consider quantized models (e.g., `llama3.2:3b-q4_0`)
+
+## Testing
+
+Run the included tests:
+
+```bash
+cargo test --package g3-providers ollama
+```
+
+All tests should pass:
+```
+running 4 tests
+test ollama::tests::test_custom_base_url ... ok
+test ollama::tests::test_message_conversion ... ok
+test ollama::tests::test_provider_creation ... ok
+test ollama::tests::test_tool_conversion ... ok
+```
+
+## Architecture
+
+The provider follows the same architecture as other g3 providers:
+
+1. **OllamaProvider**: Main struct implementing `LLMProvider` trait
+2. **Request/Response Structures**: Internal types for Ollama API
+3. **Streaming Parser**: Handles line-by-line JSON parsing
+4. **Tool Call Handling**: Accumulates and converts tool calls
+5. **Error Handling**: Robust error handling with retries
+
+## Contributing
+
+The provider is part of the g3-providers crate. To contribute:
+
+1. Add features to `ollama.rs`
+2. Update tests
+3. Run `cargo test --package g3-providers`
+4. Update this documentation
+

 ## Getting Started
 
+### Default Mode: Accumulative Autonomous
+
+The default interactive mode now uses **accumulative autonomous mode**, which combines the best of interactive and autonomous workflows:
+
+```bash
+# Simply run g3 in any directory
+g3
+
+# You'll be prompted to describe what you want to build
+# Each input you provide:
+# 1. Gets added to accumulated requirements
+# 2. Automatically triggers autonomous mode (coach-player loop)
+# 3. Implements your requirements iteratively
+
+# Example session:
+requirement> create a simple web server in Python with Flask
+# ... autonomous mode runs and implements it ...
+requirement> add a /health endpoint that returns JSON
+# ... autonomous mode runs again with both requirements ...
+```
+
+### Other Modes
+
+```bash
+# Single-shot mode (one task, then exit)
+g3 "implement a function to calculate fibonacci numbers"
+
+# Traditional autonomous mode (reads requirements.md)
+g3 --autonomous
+
+# Traditional chat mode (simple interactive chat without autonomous runs)
+g3 --chat

 **Usage**: Run G3 with the `--webdriver` flag to enable browser automation tools.
 
+## macOS Accessibility API Tools
+
+G3 includes support for controlling macOS applications via the Accessibility API, allowing you to automate native macOS apps.
+
+**Available Tools**: `macax_list_apps`, `macax_get_frontmost_app`, `macax_activate_app`, `macax_get_ui_tree`, `macax_find_elements`, `macax_click`, `macax_set_value`, `macax_get_value`, `macax_press_key`
+
+**Setup**: Enable with the `--macax` flag or in config with `macax.enabled = true`. Grant accessibility permissions:
+- **macOS**: System Preferences → Security & Privacy → Privacy → Accessibility → Add your terminal app
+
+**For detailed documentation**, see [macOS Accessibility Tools Guide](docs/macax-tools.md).
+
+**Note**: This is particularly useful for testing and automating apps you're building with G3, as you can add accessibility identifiers to your UI elements.
+
 ## Computer Control (Experimental)
 
 G3 can interact with your computer's GUI for automation tasks:

+//! Ollama LLM provider implementation for the g3-providers crate.
+//!
+//! This module provides an implementation of the `LLMProvider` trait for Ollama,
+//! supporting both completion and streaming modes with native tool calling.
+//!
+//! # Features
+//!
+//! - Support for any Ollama model (llama3.2, mistral, qwen, etc.)
+//! - Both completion and streaming response modes
+//! - Native tool calling support for compatible models
+//! - Configurable base URL (defaults to http://localhost:11434)
+//! - Simple configuration with no authentication required
+//!
+//! # Usage
+//!
+//! ```rust,no_run
+//! use g3_providers::{OllamaProvider, LLMProvider, CompletionRequest, Message, MessageRole};
+//!
+//! #[tokio::main]
+//! async fn main() -> anyhow::Result<()> {
+//!     // Create the provider with default settings (localhost:11434)
+//!     let provider = OllamaProvider::new(
+//!         "llama3.2".to_string(),
+//!         None, // Optional: base_url
+//!         None, // Optional: max tokens
+//!         None, // Optional: temperature
+//!     )?;
+//!
+//!     // Create a completion request
+//!     let request = CompletionRequest {
+//!         messages: vec![
+//!             Message {
+//!                 role: MessageRole::User,

+# Accumulative Autonomous Mode
+
+## Overview
+
+Accumulative Autonomous Mode is the **new default interactive mode** for G3. It combines the ease of interactive chat with the power of autonomous implementation, allowing you to build projects iteratively by describing what you want, one requirement at a time.
+
+## How It Works
+
+### The Flow
+
+1. **Start G3** in any directory (no arguments needed)
+2. **Describe** what you want to build
+3. **G3 automatically**:
+   - Adds your input to accumulated requirements
+   - Runs autonomous mode (coach-player feedback loop)
+   - Implements your requirements with quality checks
+4. **Continue** adding more requirements or refinements
+5. **Repeat** until your project is complete
+
+### Example Session
+
+```bash
+$ cd ~/projects/my-new-app
+$ g3
+
+🪿 G3 AI Coding Agent - Accumulative Mode
+      >> describe what you want, I'll build it iteratively
+
+📁 Workspace: /Users/you/projects/my-new-app
+
+💡 Each input you provide will be added to requirements
+   and I'll automatically work on implementing them.
+
+   Type 'exit' or 'quit' to stop, Ctrl+D to finish

+```
+
+## Key Features
+
+### 1. Requirement Accumulation
+
+Each input you provide is:
+- **Numbered sequentially** (1, 2, 3, ...)
+- **Stored in memory** for the session
+- **Included in all subsequent runs**
+
+This means the agent always has the full context of what you've asked for.
+
+### 2. Automatic Requirements Document
+
+G3 automatically generates a structured requirements document:
+
+```markdown
+# Project Requirements
+
+## Current Instructions and Requirements:
+
+1. create a simple web server in Python with Flask that serves a homepage
+2. add a /api/users endpoint that returns a list of users as JSON
+3. add error handling for 404 and 500 errors
+
+## Latest Requirement (Turn 3):
+
+add error handling for 404 and 500 errors
+```
+
+This document is passed to autonomous mode, ensuring the agent:
+- Knows all previous requirements
+- Focuses on the latest addition
+- Maintains consistency across iterations
+
+### 3. Full Autonomous Quality
+
+Each requirement triggers a complete autonomous run with:
+- **Coach-Player Feedback Loop**: Quality assurance built-in
+- **Multiple Turns**: Up to 5 iterations per requirement (configurable with `--max-turns`)
+- **Compilation Checks**: Ensures code actually works
+- **Testing**: Coach can run tests to verify functionality
+
+### 4. Error Recovery
+
+If an autonomous run fails:
+- You're notified of the error
+- You can provide additional requirements to fix issues
+- The session continues (doesn't crash)
+
+### 5. Workspace Management
+
+- Uses **current directory** as workspace
+- All files created in current directory
+- No need to specify workspace path
+- Works with existing projects or empty directories
+
+## Command-Line Options
+
+### Default (Accumulative Mode)
+
+```bash
+g3
+```
+
+Starts accumulative autonomous mode in the current directory.
+
+### With Options
+
+```bash
+# Use a specific workspace
+g3 --workspace ~/projects/my-app
+
+# Limit autonomous turns per requirement
+g3 --max-turns 3
+
+# Enable macOS Accessibility tools
+g3 --macax
+
+# Enable WebDriver browser automation
+g3 --webdriver
+
+# Use a specific provider/model
+g3 --provider anthropic --model claude-3-5-sonnet-20241022
+
+# Show prompts and code during execution
+g3 --show-prompt --show-code
+
+# Disable log files
+g3 --quiet
+```
+
+### Disable Accumulative Mode
+
+To use the traditional chat mode (without automatic autonomous runs):
+
+```bash
+g3 --chat
+
+# Alternative: legacy flag also works
+g3 --accumulative
+```
+
+This gives you the old behavior where you chat with the agent without automatic autonomous runs.
+
+## Use Cases
+
+### 1. Rapid Prototyping
+
+```bash
+requirement> create a REST API for a todo app
+requirement> add SQLite database storage
+requirement> add authentication with JWT
+requirement> add rate limiting
+```
+
+### 2. Iterative Refinement
+
+```bash
+requirement> create a data visualization dashboard
+requirement> make the charts interactive
+requirement> add dark mode support
+requirement> optimize for mobile devices
+```
+
+### 3. Bug Fixing
+
+```bash
+requirement> fix the login form validation
+requirement> handle edge case when username is empty
+requirement> add better error messages
+```
+
+### 4. Feature Addition
+
+```bash
+requirement> add export to CSV functionality
+requirement> add email notifications
+requirement> add admin dashboard
+```
+
+## Tips and Best Practices
+
+### 1. Start Simple
+
+Begin with a basic requirement, let it be implemented, then add complexity:
+
+```bash
+✅ Good:
+requirement> create a basic Flask web server
+requirement> add a homepage with a form
+requirement> add form validation
+
+❌ Too Complex:
+requirement> create a full-stack web app with authentication, database, API, and frontend
+```
+
+### 2. Be Specific
+
+The more specific you are, the better the results:
+
+```bash
+✅ Good:
+requirement> add a /api/users endpoint that returns JSON with id, name, and email fields
+
+❌ Vague:
+requirement> add users
+```
+
+### 3. One Thing at a Time
+
+Focus each requirement on a single feature or fix:
+
+```bash
+✅ Good:
+requirement> add error handling for database connections
+requirement> add logging for all API requests
+
+❌ Multiple Things:
+requirement> add error handling and logging and monitoring and alerts
+```
+
+### 4. Review Between Turns
+
+After each autonomous run completes:
+- Check the generated files
+- Test the functionality
+- Decide what to add or fix next
+
+### 5. Use Exit Commands
+
+When done:
+- Type `exit` or `quit`
+- Press `Ctrl+D` (EOF)
+- Press `Ctrl+C` to cancel current input
+
+## Comparison with Other Modes
+
+| Feature | Accumulative (Default) | Traditional Interactive | Autonomous | Single-Shot |
+|---------|----------------------|------------------------|------------|-------------|
+| **Command** | `g3` | `g3 --accumulative` | `g3 --autonomous` | `g3 "task"` |
+| **Input Style** | Iterative prompts | Chat messages | requirements.md file | Command-line arg |
+| **Auto-Autonomous** | ✅ Yes | ❌ No | ✅ Yes | ❌ No |
+| **Coach-Player Loop** | ✅ Yes | ❌ No | ✅ Yes | ❌ No |
+| **Accumulates Requirements** | ✅ Yes | ❌ No | ❌ No | ❌ No |
+| **Multiple Iterations** | ✅ Yes | ✅ Yes | ✅ Yes | ❌ No |
+| **Best For** | Iterative development | Quick questions | Pre-planned projects | One-off tasks |
+
+## Technical Details
+
+### Requirements Storage
+
+- Stored in memory (not persisted to disk)
+- Numbered sequentially starting from 1
+- Formatted as markdown list
+- Passed to autonomous mode as `--requirements` override
+
+### History
+
+- Saved to `~/.g3_accumulative_history`
+- Separate from traditional interactive history
+- Persists across sessions
+- Uses rustyline for readline support
+
+### Workspace
+
+- Defaults to current directory
+- Can be overridden with `--workspace`
+- All files created in workspace
+- Logs saved to `workspace/logs/`
+
+### Autonomous Execution
+
+- Full coach-player feedback loop
+- Configurable max turns (default: 5)
+- Respects all CLI flags (--macax, --webdriver, etc.)
+- Error handling allows continuation
+
+## Troubleshooting
+
+### "No requirements provided"
+
+This shouldn't happen in accumulative mode, but if it does:
+- Check that you entered a requirement
+- Ensure the requirement isn't empty
+- Try restarting G3
+
+### "Autonomous run failed"
+
+If an autonomous run fails:
+- Read the error message
+- Provide a new requirement to fix the issue
+- Or type `exit` and investigate manually
+
+### "Context window full"
+
+If you hit token limits:
+- The agent will auto-summarize
+- Or you can start a new session
+- Consider using `--max-turns` to limit iterations
+
+### "Coach never approves"
+
+If the coach keeps rejecting:
+- Check the coach feedback for specific issues
+- Provide more specific requirements
+- Consider increasing `--max-turns`
+
+## Future Enhancements
+
+Planned improvements:
+
+1. **Persistence**: Save accumulated requirements to disk
+2. **Editing**: Edit or remove previous requirements
+3. **Branching**: Try different approaches
+4. **Templates**: Pre-defined requirement sets
+5. **Review**: Show all accumulated requirements
+6. **Export**: Save to requirements.md
+7. **Undo**: Remove last requirement
+8. **Replay**: Re-run with same requirements
