🆕 New Features in v1.1.0

🤝 Human-in-the-Loop (HIL) Mode

Browser Copilot now includes intelligent Human-in-the-Loop capabilities that allow the AI to ask for clarification when needed:

# HIL is enabled by default - the AI will make smart decisions
browser-copilot test.md

# Disable HIL for fully autonomous execution
browser-copilot test.md --no-hil

# Enable interactive mode for real human input during testing
browser-copilot test.md --hil-interactive

Key HIL Features:

• 🤖 Smart Defaults: AI provides intelligent responses when clarification is needed
• 🔄 Multi-turn Conversations: Seamlessly continues after interruptions
• 💬 Interactive Mode: Get prompted for real input during test development
• 🛡️ Safety Features: Exit commands (exit/quit/stop) and 50-interaction limit
• 🎯 Context-Aware: Uses the same LLM as your main agent for consistency

Example HIL Interaction:

🤔 HUMAN INPUT REQUIRED
============================================================
Question: Should I click "Accept All Cookies" or "Reject All"?
Context: Testing privacy compliance on the website

💡 AI Response: I'll click "Reject All" to test the website's behavior
with minimal cookies, which is important for privacy compliance testing.
============================================================

🆕 Additional Features

🔍 Enhanced Verbose Mode

# Enable detailed step-by-step logging
browser-copilot test.md --verbose

# Logs are saved to ~/.browser_copilot/logs/
# Both console and file output for debugging

💰 Token Optimization

# Control optimization level
browser-copilot test.md --compression-level high  # 30% reduction
browser-copilot test.md --compression-level medium # 20% reduction (default)
browser-copilot test.md --compression-level low   # 10% reduction
browser-copilot test.md --no-token-optimization   # Disable

📤 Flexible Output Options

# Different output formats
browser-copilot test.md --output-format json
browser-copilot test.md --output-format yaml
browser-copilot test.md --output-format xml
browser-copilot test.md --output-format junit
browser-copilot test.md --output-format html
browser-copilot test.md --output-format markdown

# Output to file instead of console
browser-copilot test.md --output-file results.json

🎛️ Custom System Prompts

# Use custom instructions
browser-copilot test.md --system-prompt custom-prompt.txt

# Example prompt file:
cat > prompt.txt << EOF
You are a meticulous QA engineer.
Always take screenshots before and after actions.
Wait 2 seconds after each navigation.
EOF

🔧 Configuration Management

# Save current settings as defaults
browser-copilot test.md --provider openai --model gpt-4 --save-config

# Use custom config file
browser-copilot test.md --config my-config.json

# Environment variables (override config file)
export BROWSER_PILOT_PROVIDER=anthropic
export BROWSER_PILOT_MODEL=claude-3-opus
export BROWSER_PILOT_BROWSER=firefox

🎯 Context Management

Browser Copilot includes intelligent context management to optimize token usage:

# Use different context strategies
browser-copilot test.md --context-strategy sliding-window  # Default
browser-copilot test.md --context-strategy langchain-trim  # Most efficient
browser-copilot test.md --context-strategy no-op          # No trimming

# Configure window size (tokens)
browser-copilot test.md --context-window-size 10000

# See token reduction in action
browser-copilot test.md --verbose
# Output: [Sliding Window Hook] Token reduction: 48.9%

Context management can reduce token usage by 40-70% on longer tests. Learn more →
