v0.1.36

🚀 Release Highlights — v0.1.36 (2026-01-09)

📁 @path Context Handling

• Inline File Picker: Type @ to trigger autocomplete file picker popup
• Permission Syntax: @path (read), @path:w (write), @dir/ (directory)
• Context Accumulation: Paths persist across conversation turns
• Deferred Agent Creation: Docker containers launch once with all accumulated paths

🪝 Hook Framework

• PreToolUse Hooks: Permission validation and argument modification before tool execution
• PostToolUse Hooks: Content injection with tool_result or user_message strategies
• Built-in Hooks: MidStreamInjectionHook for cross-agent updates, HighPriorityTaskReminderHook for system reminders
• Pattern Matching: Glob-style patterns to match specific tools (e.g., Write|Edit, mcp__*)
• Error Handling: Configurable fail-open/fail-closed behavior with timeout enforcement

🔗 Claude Code Integration

• Native Hooks: Claude Code hooks work seamlessly within MassGen's hook framework
• Hook Result Aggregation: Multiple hooks combine results (any deny blocks, injections combine)
• Improved Docker Management: Better container lifecycle and resource handling
