OpenCode user eyes visual harness for agent workflows

Visualizing agentic harnesses is the next frontier for AI developer tools as power users outgrow terminal log limitations for complex orchestration. OpenCode's use of .md files for project rules provides flexibility but creates a visibility gap during execution. Community demand for visual abstractions like "bubbles and arrows" highlights the need for human oversight beyond raw tool calls. Early community efforts like Plannotator are already filling this niche, suggesting that agent observability is evolving into a visual design and debugging discipline.
