v0.6.0

​
Initial release

pflow v0.6.0 — compile agent reasoning into reusable workflows.Workflow engine
  • Natural language → compiled workflows
  • Save workflows for instant reuse
  • Type-aware templates with auto-parsing and nested access
  • Stdin/stdout pipe integration
  • Validation with suggestions and actionable error messages
  • Execution traces for debugging
Built-in nodes
  • File operations (read, write, copy, move, delete)
  • LLM calls (any model via llm library)
  • HTTP requests (all methods, auth, binary support)
  • Shell commands (with dangerous pattern blocking)
  • Claude Code for agentic tasks
  • MCP bridge — connect any MCP server (stdio and HTTP transports)
Agent integration
  • MCP server with 11 tools for workflow building
  • Intelligent discovery of nodes and workflows
  • Run individual nodes without workflows (registry run)
  • Structure-only mode — AI sees schema types, not data
  • Instructions system for agent guidance
  • Works with all MCP-compatible and local agents

See Quickstart for full setup.
  • Discovery features require an Anthropic API key
  • Currently supports macOS only
  • Shell commands run with user privileges (not sandboxed)
  • No conditional branching or parallel execution yet
See the Roadmap — unified model support, conditional branching, parallel execution, and benchmarking coming soon.
