yui-install

name	yui-install
description	Use when setting up a fresh YUI checkout — install, first run, or wiring the app to a chat backend / VRM / TTS / STT. Triggers on "install", "setup", "설치", "セットアップ", or a clone that has never run.

YUI install

Walk a fresh clone from git clone to a running desktop pet. The only hard requirement is one VRM model, and a default ships in the repo; chat backend, broker, TTS and STT are optional and can be wired now or later from the in-app panel (Settings → Advanced). Ask the user only for what the machine cannot tell you. Every step ends on a checkable state; do not report done before step 5 passes.

1. Prerequisites

Run pnpm -v, rustc -V, cargo -V. Any missing → stop and hand the user the two links (pnpm: https://pnpm.io/installation, Rust + Tauri v2: https://v2.tauri.app/start/prerequisites/). Done when all three print a version.

2. Dependencies

pnpm install. Done when it exits 0.

3. VRM model

The only hard requirement, and it ships: configs/avatar.json → vrm_url names /vrms/Sendagaya_Shino.vrm, tracked in git under resources/vrms/. Done when test -f resources/vrms/Sendagaya_Shino.vrm passes (a checkout that lost it: git checkout -- resources/vrms/).

Bring-your-own is optional and the user can do it later from the panel's VRM section in the Tauri app (OS picker, copied into app data). Only if they hand you a VRM 1.0 file now: copy it into resources/vrms/, set vrm_url to /vrms/<file>.vrm, and add { "id": "<stem>", "label": "<Name>", "url": "/vrms/<file>.vrm", "source": "bundled" } to available in configs/avatar.json — id must match [A-Za-z0-9._-], so slugify the stem.

4. Wiring (optional)

Ask once: "Do you want to connect a chat backend / TTS / STT now, or skip and set them later in Settings → Advanced?" Skip → go to step 5. Otherwise collect what they have. Every URL must start with http:// or https:// — the config validator rejects anything else at boot, which shows as an empty transparent window.

Value	Where it goes
Chat endpoint base URL, model id	configs/endpoints.json → chat_base_url — the API root including /v1 in both modes (e.g. http://localhost:8643/v1); the client appends /chat/completions or /responses itself — and chat_model
Chat API key	.env.local → VITE_YUI_CHAT_KEY (empty if the endpoint takes none)
Expression broker MCP URL	broker_base_url (e.g. http://localhost:3201/mcp) — published in both modes; a backend agent reads it back in Responses mode
TTS URL / model / speaker (+ key)	tts_base_url without /v1 (e.g. http://localhost:8088) / tts_model / tts_speaker, .env.local → VITE_YUI_TTS_KEY
STT URL (+ key)	stt_base_url with /v1 (e.g. http://localhost:5517/v1), .env.local → VITE_YUI_STT_KEY

Then:

• .env.local: cp -n .env.example .env.local, then set only the keys the user gave.
• configs/endpoints.json: merge the answered keys into the existing JSON; leave the rest unset — an unset URL just keeps that feature off. Keep chat_api: "chat_completions" unless the backend speaks the Responses API; then set "chat_api": "responses" and broker_base_url.

Done when node -e 'const c=JSON.parse(require("fs").readFileSync("configs/endpoints.json","utf8"));for(const k of Object.keys(c).filter(k=>k.endsWith("_url")))if(c[k]!==""&&!/^https?:\/\//.test(c[k]))process.exit(1)' exits 0 and every value the user gave is present. Full key reference and the external services (Hermes, broker, Irodori TTS): docs/guide/getting-started.md.

5. Verify

pnpm build must exit 0. Then tell the user to run pnpm tauri dev themselves (first run compiles Rust for several minutes and opens the transparent pet window). With no backend wired the character still appears and idles; chat answers with an inline "Backend not configured" pointer until Settings → Advanced is filled. macOS grants (Screen Recording for screenshot context) are in docs/guide/getting-started.md § Platform Notes.
