Screenshots and session frames are now saved to ~/.hanzo/screen/ and
the tool returns the file path. Prevents blowing up context with ~52K
chars of base64 per capture.
Run ruff check --fix and ruff format across the repo to fix ~495
auto-fixable lint errors (mostly I001 import sorting) and reformat
225 files to match the py312 target.

When name parameter is provided, screenshot saves to file and returns path
instead of base64 data. This prevents huge MCP responses.
Usage: computer(action='screenshot', name='screen.png')
Returns: {path: '/tmp/screen.png', size: ...}
- list_windows: Use unit separator (ASCII 31) instead of "|" as delimiter
to avoid parsing errors when window titles contain "|" characters
(e.g., "DNS | Records | hanzo.ai | Cloudflare")
- list_windows: Add try/except around int() parsing to skip malformed entries
- focus_window: Increase timeout from 5s to 10s
- focus_window: Add fallback to partial app name matching via System Events
when direct app activation fails (handles "Firefox" matching "Firefox Developer Edition")
MediaTool v0.4.0 - Smart video compression for Claude interpretation:
NEW ACTIONS:
- analyze: Detect activity segments (movement, scene changes)
- slice: Extract frames ONLY at activity points
- compress_session: Full pipeline for computer use sessions
ACTIVITY DETECTION:
- Frame differencing (PIL + numpy) for movement detection
- FFmpeg scene change detection for major transitions
- Activity clustering into segments with scores
- Configurable sensitivity thresholds
COMPRESSION:
- 512px max dimension for session frames (vs 768px default)
- 60% JPEG quality for aggressive compression
- Target 30 frames per 60-second session
- ~15KB per frame, ~450KB total for typical session
NEW ENV VARS:
HANZO_MEDIA_ACTIVITY_THRESHOLD=0.02
HANZO_MEDIA_SCENE_THRESHOLD=0.3
HANZO_MEDIA_SESSION_MAX_DURATION=60
HANZO_MEDIA_SESSION_TARGET_FRAMES=30
HANZO_MEDIA_SESSION_QUALITY=60
Usage:
media(action="compress_session", path="recording.mp4")
# Returns compressed keyframes + activity analysis
# Perfect for Claude to interpret computer use sessions
Added numpy>=1.26.0 dependency for frame differencing.
- Remove 'cmd' from default TOOLS list - only detected shell exposed
- Add KshTool, TcshTool, CshTool for enterprise Unix shells
- Fallback to ShellTool (smart auto-detect) if shell detection fails
- Support ksh93, pdksh, mksh as aliases for ksh
- Bump hanzo-tools-shell to 0.6.1, hanzo-mcp to 0.10.37
Major improvements to mode and tool management:
1. Essential System Tools - Critical tools (llm, consensus, config, mode,
tool, version, stats) are now ALWAYS enabled regardless of active mode.
Previously, mode system disabled all tools then only enabled mode-specific
ones, causing critical tools to be unavailable.
2. Unified 'tool' Command - Consolidates tool_install, tool_enable,
tool_disable, tool_list into single 'tool' command with actions:
- list: List all tools by category
- enable/disable: Toggle tool state
- install/uninstall: Package management
- upgrade/reload: Update tools
- self_update: Update hanzo-mcp
3. Fixed Permission Manager - Made permission_manager optional in:
- FileSystemTool base class
- ComputerTool
- ConfigTool
- ReadTool, WriteTool, EditTool
Now creates default PermissionManager if not provided.
4. Fixed Mode System - Builtin modes (hanzo, minimal, fullstack, devops,
security) are now always registered alongside hanzo-persona profiles.
Previously they were skipped when hanzo-persona was available.
5. Updated ESSENTIAL_TOOLS constant with modern tool names and added
llm, consensus, config, mode to ensure they're in all default modes.
Version bump: 0.10.19 -> 0.10.20
