v0.28.0

Release Notes

Smart Timeouts & Pre-validation

• Automatic timeout tuning based on keyword type (5s for clicks, 60s for navigation, 30s for API calls)
• Custom timeout support — pass timeout_ms per command to override defaults
• Element pre-validation — checks visibility/enabled state before actions, giving faster and clearer error messages

Reduced Token Usage

• Configurable verbosity (minimal/standard/full) to control response detail level
• List folding and page-type-aware compression

Improved Library Recommendations

• Smarter detection of library preferences from natural language scenarios with negation support ("not using Selenium")
• Confidence filtering — low-confidence recommendations are filtered out
• Conflict prevention — Browser and SeleniumLibrary are never recommended together
• Better keyword matching — verb stemming, synonym expansion, word boundary matching, URL stripping
• New session type: VISUAL_TESTING for screenshot/PDF comparison scenarios

Optional LLM-Powered Analysis

• Enable with ROBOTMCP_USE_SAMPLING=true for LLM-enhanced scenario analysis and library recommendations
• Falls back to rule-based logic on any failure

Instruction Templates

• Configure MCP behavior via ROBOTMCP_INSTRUCTIONS_TEMPLATE (minimal, browser-focused, api-focused, etc.)
• Or provide custom instructions via ROBOTMCP_INSTRUCTIONS or ROBOTMCP_INSTRUCTIONS_FILE

Debug Bridge Enhancements

• New commands: get_page_source, get_aria_snapshot, get_session_info, force_stop, import_variables
• Variable scope control (test/suite/global) and raised return limit (50 → 200)
• Auto-cleanup of stale sessions on startup
• Instance tracking to prevent ghost connections

Multi-Library Support

• Adapter layer auto-detects Browser Library, SeleniumLibrary, and AppiumLibrary
