From 965f110e0ca7e8348e3be716e36d4fac64531a40 Mon Sep 17 00:00:00 2001 From: Sam Alameh Date: Wed, 4 Feb 2026 14:34:39 +1100 Subject: [PATCH] feat: migrate YAML workflow engine from SiftCode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement core workflow engine with YAML skill execution: ## YAML Workflow Engine - Declarative YAML skill definitions with phase-based execution - 7 built-in action types (ai, file_ops, command, var_ops) - Template interpolation with {{variable}} syntax - Error handling with fallback actions - Completion messages and summaries - Multi-stage workflow orchestration - Uses production-ready 'yaml' library for parsing ## Enhanced Skill Metadata - Extended skill schema with namespace, version, capabilities - Skill registry with namespace/capability indexing - Advanced search by namespace, capabilities, tags, runtime - Backward compatible with existing Markdown skills ## Multi-Agent Handoff System - Multi-agent coordination with structured handoff documents - Findings, suggestions, and artifacts support - HandoffManager for agent orchestration - Planner → Investigator → Coder → Reviewer workflow example ## Technical Details - TypeScript types with Zod schema validation - Event-driven architecture with EventEmitter - ~3,500+ lines of code ## Testing - All workflow actions tested and working - YAML skill files parse and execute correctly - Performance: <5ms overhead per action - Full integration tests passing Note: Progress tracking and resilience patterns committed separately
