hanzo-dev a7c7be41a1 fix: restore 'version = ' prefix in 7 axis pyproject.toml files
The earlier patch-bump regex passed through a shell+python double-escape
that dropped the leading 'version = ' on each match and inserted a stray
\x01 byte, leaving '\x01"0.3.3"' instead of 'version = "0.3.3"'.
TOML parse fails (line 7 invalid statement) → CI publish-pypi 1/1 jobs
exit 1 → none of the 7 axis pkgs published.

Each TOML now parses with tomllib; ready for fresh tags.

hanzo-tools-shell

Shell execution tools for Hanzo MCP with DAG support and Shellflow DSL.

Installation

pip install hanzo-tools-shell

Tools

dag - DAG Execution Engine

Execute commands with directed acyclic graph semantics.

# Serial execution (default)
dag(["ls", "pwd", "git status"])

# Parallel execution
dag(["npm install", "cargo build"], parallel=True)

# Mixed DAG with parallel blocks
dag([
    "mkdir -p dist",
    {"parallel": ["cp a.txt dist/", "cp b.txt dist/"]},
    "zip -r out.zip dist/"
])

# Tool invocations
dag([{"tool": "search", "input": {"pattern": "TODO"}}])

# Named nodes with dependencies
dag([
    {"id": "build", "run": "make build"},
    {"id": "test", "run": "make test", "after": ["build"]},
])

zsh - Primary Shell with Shellflow DSL

Execute shell commands with optional Shellflow syntax.

# Simple command
zsh("ls -la")

# Shellflow DSL syntax
zsh("mkdir dist ; { cp a dist/ & cp b dist/ } ; zip out")

# With shell parameter
zsh("echo $BASH_VERSION", shell="bash")

Shellflow Syntax:

  • A ; B - Sequential execution
  • { A & B } - Parallel execution
  • A ; { B & C } ; D - Mixed DAG

ps - Process Management

Monitor and control background processes.

ps()                     # List all processes
ps(id="abc123")          # Get specific process
ps(kill="abc123")        # Kill process (SIGTERM)
ps(logs="abc123", n=50)  # Last 50 lines of output

Additional Tools

  • shell - Smart shell (zsh > bash fallback)
  • bash - Explicit bash execution
  • npx - Node package execution with auto-backgrounding
  • uvx - Python package execution with auto-backgrounding
  • open - Open files/URLs in system apps
  • curl - HTTP client without shell escaping issues
  • jq - JSON processor
  • wget - File/site downloads

Auto-Backgrounding

Commands that exceed the timeout (default 60s) are automatically backgrounded:

dag(["long-running-command"], timeout=30)
# If command exceeds 30s, it continues in background
# Use ps --logs <id> to view output

Performance

Shellflow DSL is optimized for high throughput:

  • Simple commands: ~7M ops/sec
  • Sequential: ~2.2M ops/sec
  • Mixed DAG: ~100k ops/sec
