## What it does

The skill runs a read-only assessment. It does not migrate anything; it produces a decision. The agent first builds a platform inventory: which clients the product supports, where each codebase lives, and whether iOS and Android sit in separate repositories. When both platforms are supported, it inspects both native codebases before recommending a path. A plan built on one platform misses native dependencies and product behavior that change the call.

Evidence collection has two modes. With source code and release artifacts available, the agent walks the repositories: app variants, CI, tests, release configuration, SDKs, permissions, app extensions, storage, auth, push, deep links, analytics. It cites repository names with file paths and line numbers so evidence stays attributable across separate codebases. When a repository is unavailable, it switches to interview mode and asks exactly one decision-changing question per turn. No questionnaire dumps.

One constraint bites early: until the scope gate passes, the first response is two lines — a question and one sentence on why it matters. No recommendations, no checkpoints, no implementation guidance at that point. Expect to answer questions rather than read a finished report. Claims get labeled `observed`, `measured`, `reported`, `assumed` or `unknown`, and the recommendation follows the evidence instead of an aggregate readiness score.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill assess-react-native-migration -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill assess-react-native-migration -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill assess-react-native-migration -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install callstackincubator/agent-skills assess-react-native-migration
```

2. **Manually: put the files in place**
- File: `.github/skills/assess-react-native-migration/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill assess-react-native-migration -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/callstackincubator/agent-skills --path skills/assess-react-native-migration
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add callstackincubator/agent-skills --skill assess-react-native-migration -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/callstackincubator/agent-skills/tree/HEAD/skills/assess-react-native-migration/SKILL.md

## When to use it
- decide whether a product can move to React Native before work starts
- inventory client platforms spread across several repositories
- compare iOS and Android implementations where they diverge
- choose between brownfield, greenfield and a checkpoint-based path
- prepare a baseline and ROI decision before implementation

## Example prompts
- assess our mobile product's readiness for a React Native migration
- audit the repositories and tell me which migration path to take
- gather evidence from the native iOS and Android codebases and list the unknowns

description: Assesses whether and how an existing mobile product should migrate to React Native. Use when auditing one or more product repositories for migration readiness, including products whose iOS, Android, and other clients live in separate directories or repositories; choosing brownfield, greenfield, or a checkpoint-based path; defining a representative trial; or preparing a baseline and ROI decision before implementation. When product scope or material evidence is unavailable, grills the stakeholder with exactly one question per turn instead of sending a questionnaire.

# Assess React Native Migration

Produce a read-only migration decision. Diagnose the product and delivery system; do not execute the migration.

## Establish Product Scope

Run the assessment from a workspace that exposes as many production client codebases as possible. The current checkout is not evidence that it contains the whole product.

Before assessing readiness:

1. Inspect the current repository and every workspace root available to the agent.
2. Infer supported client platforms from product documentation, CI, release configuration, workspace manifests, submodules, and references to sibling repositories.
3. Locate each production client codebase, including separate native iOS and Android repositories, app variants, and any web client relevant to staffing or proposed code sharing.
4. Record a platform inventory with the client, repository or path, evidence of product membership, and access status.

When iOS and Android are both supported, inspect both native codebases before recommending a path. If a codebase remains unavailable, mark its evidence `unknown`, state that the assessment covers only the accessible platforms, and lower confidence accordingly. Do not infer that a platform is unsupported merely because its project is absent from the current repository.
