| Elicitation - Human-in-the-loop | [#60](https://github.com/nesquikm/mcp-rubber-duck/issues/60) | Medium-High | Low-Medium |
## Suggested Phases
- **Phase 1** (Foundation): outputSchema (#53) → Streamable HTTP (#57) + Streaming (#47)
- **Phase 2** (Differentiation): Duck Hypothesis (#45) + Duck Calibrate (#40) + Duck Deliberate (#35)
- **Phase 3** (Platform): Resources (#48) + Smart Router (#10) + Fallback Chains (#20)
- **Phase 4** (Agentic): Duck Autopilot (#12)
## What We Already Have
| Feature | Status | Details |
|---------|--------|---------|
| MCP Apps / Ext-Apps | Done | 4 interactive UIs: compare, vote, debate, usage-stats |
| Streaming / Progress | Done | `ProgressReporter` via MCP `notifications/progress` |
| Async / Tasks | Done | MCP experimental tasks API with cancellation |
| Structured output | Partial | Dual-content workaround, no formal `outputSchema` → #53 |
## Client Support Matrix
| Feature | Claude Desktop | Claude Code | Cursor | VS Code/Copilot | Zed |
|---------|---------------|-------------|--------|-----------------|-----|
| outputSchema | - | - | Yes | Yes | Yes |
| Elicitation | - | - | Yes | Yes | - |
| Async Tasks | - | - | - | Partial | - |
| Streaming Progress | - | - | Partial | Yes | - |
| resource_link | Partial | Partial | Yes | Yes | Yes |
| listChanged | - | - | Yes | Yes | Yes |
