- MCPMesh: Register agents as MCP servers
- MCPAgent: Call tools on other agents
- run_mcp_consensus: N rounds of discussion via MCP
- create_mesh: Convenience factory
Each agent in consensus is available as MCP to every other.
- New package: hanzo-metastable-consensus
- Two-phase finality: Sampling + Finality
- Used by hanzo-tools-agent for consensus action
- Reference: https://github.com/luxfi/consensus
Consolidated agent tool with actions:
- run: single agent execution (claude -p default)
- dag: DAG execution with dependencies and {dep_id} injection
- swarm: work distribution with max_concurrent semaphore
- consensus: Lux Quasar protocol (Nova + Quasar phases)
- dispatch: different agents for different tasks
Removed hanzo-agents SDK dependency. Lightweight CLI execution.
Consensus: https://github.com/luxfi/consensus
Add three new shell tools that bypass shell escaping issues by using
subprocess with list arguments instead of shell interpretation:
- curl: HTTP client with proper JSON body handling
- jq: JSON processor with direct filter passing
- wget: File/site downloads with mirror mode support
These tools solve the common problem of shell escaping nightmares
when working with complex JSON or special characters.
Updates:
- Added CurlTool, JqTool, WgetTool to hanzo-tools-shell
- Updated __all__ exports and TOOLS list
- Added tools to entrypoint_loader PACKAGE_TOOL_PREFIXES
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
- git_search.py: All 6 subprocess.run calls converted to asyncio.create_subprocess_exec
- search_tool.py: All 6 subprocess.run + 3 blocking file reads converted to async
- npx.py: Converted to asyncio.create_subprocess_exec with proper timeout
- uvx.py: Both subprocess calls converted to async with timeout handling
- open.py: Platform openers converted to async fire-and-forget pattern
All tools now use non-blocking async I/O for better concurrency.
Tests: 31/31 passing.
- Delete deprecated agent_tool_v1_deprecated.py and swarm_tool_v1_deprecated.py
- Keep CriticTool as name='critic' (not code_review) per user request
- Add missing stub classes for CLI agents when hanzo-agents unavailable
- Fix NameError: ClaudeCodeAgent not defined in tests
- Document hanzo-mcp vs hanzo-tools-* architecture in CLAUDE.md
Updated tool descriptions with DISPLAY INSTRUCTIONS to guide LLM output rendering:
- read.py: Show output in fenced code block with language hint
- write.py: Show brief status message
- edit.py: Show diff in fenced code block
- find_tool.py: Show formatted file list directly
This helps agent and other LLMs render tool output more readably
instead of showing raw JSON.
- Add MCPResourceDocument.to_readable_string() for human-readable output
- Update search, find, lsp, refactor tools to use readable format
- Cleaner to_json_string() that doesn't double-wrap data
- Better formatted results with:
- Search stats and timing info
- Numbered results with file:line locations
- Truncated long matches for readability
- Pagination info
- Sync improvements to hanzo-tools-core package
Add runtime check to provide better error message if ProcessManager()
returns None. This should never happen with proper singleton pattern,
but helps diagnose issues in edge cases.
- Add 30s timeout to each search engine (grep, ast, lsp, git)
- Fix NoneType error when process_manager unavailable in auto_timeout
- Prevents LSP engine from hanging indefinitely on large codebases
- DAG commands that exceed timeout now auto-background instead of failing
- Backgrounded processes return SUCCESS status so DAG continues
- Register backgrounded processes with ProcessManager for ps tool tracking
- Async log capture for backgrounded process output
- Enable standalone zsh tool for simple single-command execution
- All I/O uses aiofiles for non-blocking async operations
- Kill any backgrounded process without affecting DAG completion
- Check Homebrew paths first (/opt/homebrew/bin, /usr/local/bin)
- Prefer zsh, fallback to bash if not available
- Support both Apple Silicon and Intel Macs
