**Status:** ✅ Complete (Archived)
**Created:** 2025-12-28
**Archived:** 2025-12-29
**Series:** LX (Language/Platform eXtension)
**Depends on:** LX-02 (Agent Portability Analysis)
**Superseded by:** LX-04 (Multi-Agent Framework) for implementation

---

## Summary

This proposal completed its documentation phase. All implementation work continues in [LX-04](./LX-04-pi-agent-support.md).

---

## Phase 1: Documentation (✅ Complete)

### Output

Created `docs/guides/` directory with integration guides:

| File | Content |
|------|---------|
| `multi-agent.md` | Overview, comparison matrix, MCP configuration |
| `cline.md` | .clinerules template, Plan Mode mapping |
| `cursor.md` | .cursorrules, hooks.json, pytest interception |
| `aider.md` | CONVENTIONS.md, auto-lint integration |

### Guide Features

Each guide includes:
1. **Quick Start** — 5 minutes to running
2. **Complete Templates** — Copy-paste ready
3. **MCP Configuration** — Multiple options (uvx, venv, global)
4. **Feature Mapping** — Comparison with Claude Code
5. **Troubleshooting** — Common issues

## Superseded Phases

Phase 2-6 were absorbed into [LX-04: Multi-Agent Support Framework](./LX-04-pi-agent-support.md):

| Phase | Original Scope | LX-04 Coverage |
|-------|----------------|----------------|
| Phase 2 | Template Generation | Manifest-driven + Copy-Sync |
| Phase 3 | MCP Testing | Included in agent phases |
| Phase 4 | Hooks Portability | Python SSOT + code generation |
| Phase 5 | Doc Integration | Phase 7 |
| Phase 6 | Community Outreach | Post-implementation |
