Don Cheli: Migration Planner

Instructions

  1. Identify source stack/version and target stack/version
  2. Scan the codebase (or description) to inventory affected modules, dependencies, patterns
  3. Build the equivalence map: source construct → target construct
  4. Detect breaking changes (API removals, semantic shifts, config format changes)
  5. Produce a wave plan ordered by risk and dependency graph (low-risk, foundational first)
  6. Generate atomic migration tasks, each independently deployable or reviewable

Output Format

## Migration Plan: <source> → <target>

### Equivalence Map
| Source                  | Target                        | Notes          |
|-------------------------|-------------------------------|----------------|
| <old pattern/API>       | <new pattern/API>             | …              |

### Breaking Changes
1. <change> — Impact: <high/medium/low> — Mitigation: …
…

### Wave Plan
**Wave 1 — Foundation (lowest risk)**
- [ ] Task: …
- [ ] Task: …

**Wave 2 — Core Migration**
- [ ] Task: …

**Wave 3 — Cleanup & Optimization**
- [ ] Task: …

### Rollback Strategy
…

### Definition of Done
- [ ] All tests pass on target stack
- [ ] No references to deprecated source APIs remain
- [ ] Performance benchmarks ≥ baseline

Quality Gate

  • Every breaking change must have an explicit mitigation
  • Wave 1 must be deployable independently without completing later waves
  • If the migration affects >10 files, confirm scope with the user before generating all tasks

Do not use this skill when

  • The change is a minor dependency bump with no API changes (use a standard fix commit)
  • The user only wants to understand differences, not plan tasks (use doncheli-reasoning instead)
