- 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
