## What it does

This skill runs a migration through five subagents. `oracle` researches the target, `phoenix` assesses codebase impact, and `plan-agent` creates a phased plan. `kraken` makes the changes, then `surveyor` reviews the result.

Research covers breaking changes, new APIs, deprecated features, official guides, and common pitfalls. The impact pass identifies affected files, dependency conflicts, patterns to update, and test coverage. Its plan includes independently testable phases and a rollback strategy.

During implementation, the workflow runs tests after every change and stops when they fail. Use `--phase N`, `--dry-run`, `--rollback`, or `--parallel` to run one phase, plan without changes, execute a rollback, or run old and new versions side by side. Dependency conflicts and deprecated APIs are a reason to start with `--dry-run`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill migrate -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/migrate/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/migrate/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill migrate -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/migrate/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill migrate -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/migrate/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 migrate
```

2. **Manually: put the files in place**
- File: `.github/skills/migrate/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill migrate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/migrate
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/migrate/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill migrate -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/migrate/SKILL.md

## When to use it
- upgrade a framework version
- move code from one technology to another
- find files that use deprecated APIs
- split a migration into testable phases
- review database migration changes

## Example prompts
- Run `/migrate React 17 → 18`
- Create a plan with `/migrate MongoDB → PostgreSQL --dry-run`
- Run the first phase: `/migrate Python 3.9 → 3.12 --phase 1`

# /migrate - Migration Workflow

Safe migrations for frameworks, languages, and infrastructure.

## When to Use

- "Migrate to X"
- "Upgrade framework"
- "Move from X to Y"
- "Upgrade Python/Node/etc."
- "Migrate database"
- Framework version upgrades
- Language migrations
- Infrastructure changes

## Workflow Overview

```
┌──────────┐    ┌──────────┐    ┌────────────┐    ┌──────────┐    ┌───────────┐

```

## Agent Sequence

| # | Agent | Role | Output |
|---|-------|------|--------|
| 1 | **oracle** | Research target framework/version | Research report |
| 2 | **phoenix** | Analyze current codebase for migration impact | Impact analysis |
| 3 | **plan-agent** | Create phased migration plan | Migration plan |
| 4 | **kraken** | Implement migration changes | Code changes |
| 5 | **surveyor** | Review migration for completeness | Migration review |

## Why Extra Gates?

Migrations are high-risk:
- Breaking changes between versions
- Dependency conflicts
- Data format changes
- API deprecations

The extra research and review phases catch issues early.

## Execution

### Phase 1: Research Target

```
Task(
  subagent_type="oracle",
  prompt="""
  Research migration target: [TARGET]

  Investigate:
  - Breaking changes from current version
  - New APIs and patterns
  - Deprecated features we use
  - Migration guides from official docs
  - Common pitfalls and solutions

  Output: Migration research report
  """
)
```

### Phase 2: Analyze Current State

```
Task(
  subagent_type="phoenix",
  prompt="""
  Analyze codebase for migration: [FROM] → [TO]

  Identify:
  - Files using deprecated APIs
  - Dependency conflicts
  - Patterns that need updating
  - Test coverage of affected areas
  - Risk areas (critical paths)

  Output: Impact analysis with affected files
  """
)
```

### Phase 3: Plan Migration

```
Task(
  subagent_type="plan-agent",
  prompt="""
  Create migration plan: [FROM] → [TO]

  Research: [from oracle]
  Impact: [from phoenix]

  Plan should:
  - Be phased (incremental if possible)
  - Each phase independently testable
  - Include rollback strategy
  - Prioritize critical path stability

  Output: Phased migration plan
  """
)
```

### Phase 4: Implement

```
Task(
  subagent_type="kraken",
````
