• 5 Core Agents: @hive (lifecycle coordinator), @pm (requirements), @arch (architecture), @dev (TDD implementation), @reviewer (code review + commit)
• Contract-First Design: Defined input/output contracts between agents (hive.json, pm.json, arch.json, dev.json)
• One Command: /omt "goal" → autonomous planning → consensus gate → execution
• Quality Assurance: Automated code review and git commit workflows
• State Synchronization: PostToolUse hooks for automatic state tracking

Installation:

Apple Podcasts

Fetch Apple Podcasts episode audio download URLs:

• iTunes API Pipeline: Resolves episode audio URLs via iTunes Lookup API + RSS feed parsing
• Zero Browser: No scraping needed — pure HTTP API workflow
• Auto-Triggered: Activated when you share an Apple Podcasts URL or ask to download podcast audio

Installation:

/plugin install apple-podcasts

Context Flow (Experimental)

Experimental agentic workflow based on the Context + Goal + Tools principle:

• Core Idea: Agents are defined by what context they see and what tools they have — not by role-based personas
• 4-Phase Pipeline: Research → Plan → Implement → Review, with contract validation between phases
• Contract as Context: Each phase's output schema serves as binding constraints for the next phase, enforced structurally (not via prompt)
• Minimal Agent Definitions: Agent prompts are 1-16 lines; constraints come from context isolation and tool restrictions
• Human Gate: Plan review before implementation — the highest-leverage review point
• Single Command: /cf "goal" runs the full pipeline

Installation:

/plugin install context-flow
