What it does
Sim Preview is an agent skill from K9i-0/ccpocket. iOSシミュレーターで動くFlutterアプリをExpo Device HubとTailscale HTTPSでスマホのブラウザへ配信・操作するときに使う。
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/sim-preview.sh`).
It sits in Mobile, covering Cross-platform mobile apps. It works with Expo, Flutter and iOS. The repository describes itself as: Mobile client for Codex and Claude — control coding agents from your phone via WebSocket bridge. The licence is MIT.
When your agent uses it
- Tasks that involve Cross-platform mobile apps
Example prompts
- “/sim-preview”
Requirements
- Node.js
- A Bash shell
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 8354ffd. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
xcrunbashnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sim Preview loads about 711 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 119 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- iOSシミュレーターで動くFlutterアプリをExpo Device HubとTailscale HTTPSでスマホのブラウザへ配信・操作するときに使う。
Simulator Preview (Expo Device Hub)
MacのiOSシミュレーターを Expo Device Hub → Tailscale Serve (HTTPS) → スマホのブラウザ で配信する。Expoプロジェクトは不要。Flutterアプリをそのまま確認・操作できる。
既定はH.264・30fps・最大1000px・2.5Mbps。Device Hub 0.10.1でccpocketの配信を確認し、ユーザーから旧VNC方式より快適との評価を得た設定。TrollVNC / noVNCを既定に戻さない。
1. シミュレーターとアプリ
xcrun simctl list devices booted対象アプリが既に動いていれば再利用する。起動が必要な場合やhot reloadには mobile-automation を使う。テスト用Bridgeが必要なら8766を使い、本番8765を停止・再起動しない。
前提はMac + Xcode、Node.js/npm、MacとスマホのTailscale接続。CoreSimulatorへのアクセスがサンドボックスで拒否された場合は、シミュレーターの故障と判断せず適切な実行権限で再確認する。
2. Device Hubを起動
既存のDevice HubとTailscale Serveの状態を確認し、目的の配信が動いていれば再利用する。
lsof -nP -iTCP:3400 -sTCP:LISTEN
tailscale serve status新規起動には以下を使う。スクリプトはDevice Hubのみを起動し、アプリ起動やTailscale設定は別に行う。
bash .claude/skills/sim-preview/scripts/sim-preview.sh- ローカル待受は
127.0.0.1:3400。npm経由で検証済みバージョンを取得し、リポジトリの依存関係は変更しない。 - 長時間実行できるツールセッションで起動し、停止用のセッションID / PIDとログを控える。
- 3400が使用中ならプロセスを勝手に停止せず、既存配信を確認するか
SIM_PREVIEW_PORT=3401などの空きポートを選ぶ。起動ログの実際のポートを確認する。 - 更新時は対象バージョンの
--helpを確認する。配信設定の変更はブラウザの「Stream options」からも試せる。
3. Tailscale内限定のHTTPSを設定
リモートのH.264 / WebRTCにはHTTPSが必要。 http://<Tailscale IP>:3400 ではMJPEGへフォールバックする。localhostでH.264が動くだけではスマホ向け検証の完了にならない。
tailscale serve status に今回のHubを指す設定があれば再利用する。未設定なら、起動ログのポートに合わせて設定する。
tailscale serve --bg --https=443 http://127.0.0.1:3400- 443に別サービスの設定がある場合は上書きせず、未使用のHTTPSポート（例:
--https=8443）を選ぶ。 - Serveが未有効なら、CLIが出力した有効化URLを案内する。ログインが必要ならユーザーに操作を依頼し、完了後に上記コマンドを再実行する。有効化だけでは転送設定が作成されないことがある。
- 出力された
https://<MacのDNS名>.ts.net[:port]/を使う。ホスト名を固定値で書かない。 tailscaleがPATHにない環境では/Applications/Tailscale.app/Contents/MacOS/Tailscaleを確認する。- インターネット公開の
tailscale funnelは使用しない。
4. 配信確認とユーザーへの案内
実際のHTTPS URLをブラウザで開き、以下を確認する。
- 対象シミュレーターが
Liveになり、ccpocketの映像が表示される。 - 「Stream options」でHTTP codecが H.264、Video FPSが 30 FPS、Max sizeが 1000 px、Video bitrateが 2.5 Mbps になっている（意図して調整した場合はその値）。
スマホのTailscaleをONにして開くHTTPSリンクを案内する。ユーザーにタップ・スクロール・文字入力の体感を試してもらい、Mac側の表示確認とスマホ側の確認結果を区別して報告する。遅延が残る場合は同画面で解像度やビットレートを調整して比較する。
初回のページ遷移がタイムアウトしても、再度画面状態を確認すると Live になっている場合がある。MJPEGになる場合はHTTPS URLとコーデック設定を確認する。
5. 継続・終了
プレビュー依頼中はDevice HubとHTTPS転送を残す。コード変更後のhot reloadはFlutter側で行い、配信画面で結果を確認する。
停止を依頼されたら、自分が起動したHubのセッションまたはPIDだけを停止する。今回追加したServe設定も不要になった場合のみ、対象HTTPSポートの転送を解除する。
# 今回443に追加した転送を終了する場合。別ポートなら置き換える。
tailscale serve --https=443 off既存の共有設定を巻き込む tailscale serve reset やプロセス名による一括killは使わない。
