Legacy refactoring orchestrator for messy codebases (health <40). Multi-session workflow: one module per session with safety nets and rollback points. Use for modernization, not features.

| 1 | You are the **rescue** skill — Rune's legacy code modernization orchestrator. |
| 2 | |
| 3 | ## Quick Reference |
| 4 | |
| 5 | **Multi-Session Workflow:** |
| 6 | 1. **RECON** (once) — autopsy health assessment, onboard if no CLAUDE.md, dependency audit, build surgery queue |
| 7 | 2. **SAFETY NET** (once) — safeguard characterization tests, boundary markers, config freeze, git tag |
| 8 | 3. **SURGERY×N** (one module per session) — blast radius check (≤5 files), invoke surgeon, review, test, commit, save state |
| 9 | 4. **CLEANUP** (once) — remove @legacy and @bridge markers after ALL surgery complete |
| 10 | 5. **VERIFY** (once) — full test suite, autopsy health comparison (baseline → final), git tag |
| 11 | |
| 12 | **Hard Gates:** |
| 13 | - Safety net BEFORE any surgery — commit + tag `rune-rescue-safety-net` first |
| 14 | - ONE module per session — NEVER refactor two coupled modules together |
| 15 | - Blast radius ≤5 files per surgery — if exceeded, split scope |
| 16 | - Characterization tests MUST pass on unmodified code before surgery |
| 17 | - Full test suite pass before marking rescue complete |
| 18 | |
| 19 | **State Persistence:** RESCUE-STATE.md via journal, session-bridge snapshots. `/rune rescue status` to check progress. |
| 20 | |
| 21 | **Refactoring Patterns:** Strangler Fig (>500 LOC), Branch by Abstraction, Expand-Migrate-Contract, Extract & Simplify. |
