We're excited to release MassGen v0.1.36, adding @path Context Handling & Hook Framework!🚀 Reference files inline with `@path` syntax - just type `@` to trigger an autocomplete file picker (like Claude Code). Extend agent behavior with PreToolUse/PostToolUse hooks for permission validation, content injection, and custom processing. Plus: Claude Code native hooks integration and improved Docker resource management.

**Key Features:**

**@path Context Handling** - Inline context path references:
- Type `@` in CLI for autocomplete file picker popup
- `@path` (read), `@path:w` (write), `@dir/` (directory)
- Context accumulation across turns
- Deferred agent creation - Docker launches once with all paths

**Hook Framework** - General hook framework for agent lifecycle events:
- PreToolUse hooks for permission validation and argument modification
- PostToolUse hooks for content injection (tool_result or user_message strategies)
- Built-in MidStreamInjectionHook for cross-agent updates without losing work
- Custom Python callable hooks with glob-style pattern matching
- Configurable fail-open/fail-closed error handling

**Claude Code Integration** - Native hooks support for Claude Code workflows
