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
- Add shell_detect.py module with comprehensive shell detection:
- Detects login shell from passwd/Directory Services
- Detects invoking shell by walking parent processes
- Prefers Homebrew shell paths on macOS
- Supports override via HANZO_MCP_SHELL and HANZO_MCP_FORCE_SHELL
- Update hanzo-tools-shell to only include detected shell in TOOLS list
- HANZO_MCP_ALL_SHELLS=1 to expose all shells
- get_shell_tools() now supports shell_override parameter
- Add CLI options to hanzo-mcp:
- --shell: Specify shell by name or path
- --all-shells: Expose all shell tools
- Updated --force-shell to include fish and dash
- Bump hanzo-tools-shell to 0.6.0 (published to PyPI)
- Bump hanzo-mcp to 0.10.36
Detection order: HANZO_MCP_SHELL > HANZO_MCP_FORCE_SHELL > CLI --shell >
invoking shell > login shell > $SHELL
- Rename package from hanzoai to hanzo-agent (avoid conflict with root)
- Add to workspace members
- Add numpy as required dependency (used by memory module)
Converts hanzo-agent from git submodule to regular directory.
This enables simpler cross-package refactoring and unified CI/CD.

- Change default timeout from 45s to 30s for faster response
- Fix potential hanging in run_shell by using stream reading instead of communicate()
- Add start_new_session=True to prevent zombie processes
- Proper cleanup on error with process.kill()
- All stream reading uses chunked async reads (8KB chunks)
- Partial output preserved when backgrounding
53 tests pass in 1.1s.
- Remove ShellTool from TOOLS list (too ambiguous)
- Keep zsh, bash, fish, dash as specific shell tools
- Update get_shell_tools to include bash
- Fix test imports (ShellTool now in shell_tools.py)
- Update tests to expect cmd as primary tool
- Verify asyncio.gather + uvloop works correctly
hanzo-tools-shell: 0.5.1 → 0.5.2
- Add shellflow.py: minimal DSL for DAG execution
- Syntax: A ; B (sequential), { A & B } (parallel)
- Compiles to JSON AST, S-expressions, or command list
- Supports quoted strings, &&, ||, nested braces
- Performance optimizations:
- Precompiled regex with local variable caching
- Fast-path for simple/sequential commands (8x faster)
- LRU cache for repeated patterns
- Full type annotations for mypyc compilation
- Restore dag as separate semantic tool:
- dag: for parallel/serial/graph execution
- zsh: for shell commands with shellflow DSL
- Both support nested arrays for auto-parallel
- Add comprehensive test suite (53 tests):
- Tokenizer, parser, normalization tests
- S-expression and command conversion tests
- Performance benchmarks
- Integration tests with real shell execution
Performance: ~7M ops/sec for simple commands,
~220k ops/sec for sequential, ~100k ops/sec for mixed DAGs
Shellflow syntax:
A ; B ; C → sequential
{ A & B & C } → parallel
A ; { B & C } ; D → mixed
Usage:
zsh("mkdir dist ; { cp a dist/ & cp b dist/ } ; zip out.zip dist/")
Compiles to JSON AST then executes via DAG.
Bump to v0.4.0
- ZshTool now includes full DAG functionality (serial, parallel, graph)
- Single "zsh" command for all shell operations
- Usage: zsh("ls") or zsh(["cmd1", "cmd2"]) or zsh([...], parallel=True)
- DagTool kept in codebase for backwards compatibility
- Removed DagTool from default TOOLS list
- Bump hanzo-tools-shell to v0.3.1
