# muyue

AI-powered development environment assistant by **La Légion de Muyue**.

## What it does

`muyue` is a single binary (frontend embedded) that transforms your entire development environment:

- **Desktop app** — React web UI served locally, auto-opens in your browser
- **Scans** your system for tools, runtimes, and configs
- **Installs** missing tools automatically (Crush, Claude Code, BMAD, Starship, runtimes...)
- **Updates** everything in the background
- **Profiles** you on first run to personalize the experience
- **Unifies** control of Crush and Claude Code from one interface
- **Orchestrates** AI agents via MiniMax M2.7
- **Configures** MCP servers, LSPs, and skills automatically
- **i18n** — Full FR/EN support with keyboard layout awareness (AZERTY, QWERTY, QWERTZ)
- **4 themes** — Cyberpunk Red, Cyberpunk Pink, Midnight Blue, Matrix Green

## Browser Extension

Muyue ships a **browser extension** (Chrome, Edge, Firefox) that replaces the manual snippet injection for the Tests tab:

- **Auto-injects** the Muyue test client on every HTTP/HTTPS page — no more copy-paste
- **Captures console** errors/warnings in real-time
- **Native screenshots** via `captureVisibleTab` — pixel-perfect
- **Side Panel** (Chrome/Edge) and **Sidebar** (Firefox) for status monitoring
- **Badge** shows active session count or server status

### Install from source

```bash
cd extension
npm install
npm run build          # Chrome/Edge → .output/chrome-mv3/
npm run build:firefox  # Firefox → .output/firefox-mv2/
```

Then load the extension:
- **Chrome/Edge**: `chrome://extensions` → Developer mode → Load unpacked → select `extension/.output/chrome-mv3/`
- **Firefox**: `about:debugging#/runtime/this-firefox` → Load temporary Add-on → select any file in `extension/.output/firefox-mv2/`

### Download pre-built

Extension `.zip` files are attached to every [release](https://gitea.legion-muyue.fr/Muyue/MuyueWorkspace/releases):

- `muyue-extension-*-chrome.zip` — Chrome Web Store ready
- `muyue-extension-*-firefox.zip` — Firefox Add-ons ready
- `muyue-extension-*-sources.zip` — Required source for Firefox Add-ons review

### Development

```bash
cd extension
npm run dev            # Chrome dev mode with HMR
npm run dev -- --browser firefox  # Firefox dev mode
```

## Tech Stack

| Layer | Technology |
|-------|-----------|
| **Backend** | Go 1.24 — single binary, no runtime dependencies |
| **Frontend** | React 19, Vite 8 — embedded via `go:embed` |
| **Styling** | CSS custom properties, 4 built-in themes |
| **i18n** | Custom FR/EN system with keyboard layout awareness |
| **CLI** | Charm (Bubble Tea, Huh) — for setup wizard, profiler, and CLI commands |
| **AI** | MiniMax M2.7 — orchestration |

## Install

```bash
go build -o muyue ./cmd/muyue/
```

Or with Make:

```bash
make build
make install-local
```

The frontend is built automatically during `make build` (runs `npm ci && npm run build` in `web/`).

## Usage

```bash
muyue              # Launch desktop app (opens browser)
muyue --port=8080  # Launch on a specific port
muyue --no-open    # Launch without opening the browser
muyue scan         # Scan system
muyue install      # Install missing tools
muyue update       # Check and apply updates
muyue setup        # Run setup wizard
muyue config       # Show configuration
muyue doctor       # Diagnose configuration issues
muyue version      # Show version
```

### LSP Management

```bash
muyue lsp scan              # Scan for installed LSP servers
muyue lsp install           # Install LSPs for configured languages
muyue lsp install gopls     # Install a specific LSP
```

### MCP Server Configuration

```bash
muyue mcp config            # Configure MCP servers for Crush and Claude Code
muyue mcp scan              # Scan available MCP servers
```

### Skills Management

```bash
muyue skills list           # List installed skills
muyue skills init           # Install built-in skills
muyue skills show <name>    # Show skill details
muyue skills generate <name> <desc> [crush|claude|both]  # AI-generate a skill
muyue skills deploy         # Deploy skills to Crush and Claude Code
muyue skills delete <name>  # Delete a skill
```

## Desktop App — 4 Tabs

The web UI is organized into 4 tabs with a cyberpunk dark theme. Navigate with `Ctrl+1` through `Ctrl+4`.

### ■ Dashboard

System overview with sub-tabs:
- **Tools** — installed/missing tools with status badges and version info
- **Notifications** — activity log with colored severity
- **Workflows** — quick actions (install missing, check updates, rescan, configure MCP)

### ⟨⟩ Studio

AI chat interface with a sidebar containing 3 panels:

| Panel | Description |
|-------|-------------|
| **Chat** | AI conversation, `/plan <goal>` to start workflows |
| **Agents** | Status of Crush and Claude Code agents |
| **Workflows** | Plan→Execute workflow controls |

### $ Shell

Split-view: terminal emulator on the left (sends commands to the Go backend), collapsible AI assistant panel on the right. Full command history with `↑`/`↓` navigation.

### ⚙ Config

## Configuration

Config stored at `$XDG_CONFIG_HOME/muyue/config.yaml` (defaults to `~/.config/muyue/config.yaml`).

API keys are encrypted at rest using AES-256-GCM with a machine-local key stored in `~/.muyue_key`.

First run launches an interactive profiling wizard that:
1. Asks your name, pseudo, email
2. Detects your languages and editor
3. Chooses your AI provider
4. Scans your system
5. Installs missing tools

## Themes

4 built-in themes, selectable from the Config tab:

| Theme | Accent Color |
|-------|-------------|
| Cyberpunk Red | `#FF0033` |
| Cyberpunk Pink | `#FF1A8C` |
| Midnight Blue | `#0088FF` |
| Matrix Green | `#00FF41` |

Themes are applied via CSS custom properties injected at runtime. All colors (30+ variables) adapt automatically.

## i18n & Keyboard Layouts

- **Languages**: Français, English
- **Keyboard layouts**: AZERTY (fr-FR), QWERTY (en-US), QWERTZ (de-DE)
- Keyboard layout affects displayed shortcuts in the status bar (e.g., `Ctrl+&-é-"-'` on AZERTY vs `Ctrl+1-4` on QWERTY)
- Preferences saved to backend and synced across sessions

## Security

- API keys encrypted at rest (AES-256-GCM) with a per-machine key
- Config files use restrictive permissions (0600)
- MCP config files use restrictive permissions (0600)
- Terminal API executes commands via shell — only accessible on localhost

## Cross-Platform

Built for Linux (primary), macOS, and Windows. WSL supported.

Single binary includes both CLI and embedded web frontend.

## Contributing — GitFlow Workflow

This project uses a **lightweight GitFlow** with 2 permanent branches and conventional commits.

### Branch model

```
feature/xxx  ──PR (squash)──▶  develop  ──PR (merge)──▶  main
fix/xxx      ──PR (squash)──▶  develop
hotfix/xxx   ──PR (squash)──▶  main (+ backport develop)
```

| Branch | Purpose | Permanent? |
|--------|---------|------------|
| `main` | Production — stable releases only | Yes |
| `develop` | Integration — all features merge here first | Yes |
| `feature/*` | New feature or enhancement | No (deleted after merge) |
| `fix/*` | Bug fix | No |
| `hotfix/*` | Urgent fix on production | No |

### Release channels

| Event | Channel | Tag format | Prerelease? |
|-------|---------|------------|-------------|
| PR merge → `develop` | **Beta** | `vX.Y.Z-beta.N` | Yes |
| Merge `develop` → `main` | **Stable** | `vX.Y.Z` | No |

### CI/CD Pipelines

| Workflow | Trigger | What it does |
|----------|---------|--------------|
| `ci-pr.yml` | PR to `main` or `develop` | vet + test + build (no release) |
| `ci-develop.yml` | Push to `develop` | vet + test + build all platforms + create beta release |
| `ci-main.yml` | Push to `main` | vet + test + build all platforms + update CHANGELOG.md + create stable release |

All CI pipelines build the frontend (`npm ci && npm run build`) before Go vet/test/build.

### Step-by-step: contribute a feature

```bash
# 1. Create your branch from develop
git checkout develop
git pull
git checkout -b feature/my-feature

# 2. Work, commit with conventional messages
git commit -m "feat: add amazing thing"
git commit -m "docs: update usage"

# 3. Push and create a PR to develop (squash merge)
git push -u origin feature/my-feature
# → Create PR on Gitea: feature/my-feature → develop
# → CI runs ci-pr.yml (test + vet + build)
# → Squash & merge the PR
# → ci-develop.yml triggers: beta release created
```

### Step-by-step: release a stable version

```bash
# 1. Bump the version in internal/version/version.go
#    Change: Version = "0.2.1"  →  Version = "0.3.0"
#    Commit on develop:
git checkout develop
# (edit internal/version/version.go)
git commit -m "chore: bump version to 0.3.0"
git push

# 2. Create a PR from develop to main
# → CI runs ci-pr.yml (test + vet + build)
# → Merge the PR
# → ci-main.yml triggers:
#    - Builds all platforms
#    - Auto-generates changelog from conventional commits
#    - Updates CHANGELOG.md
#    - Creates stable release v0.3.0
```

### Step-by-step: hotfix on production

```bash
# 1. Create hotfix branch from main
git checkout main
git pull
git checkout -b hotfix/critical-fix

# 2. Fix and commit
git commit -m "fix: resolve critical issue"

# 3. Create PR to main (squash merge)
# → CI runs, then ci-main.yml creates a new stable release

# 4. Backport to develop
git checkout develop
git merge hotfix/critical-fix
git push
```

### Versioning — How it works

**The base version (`X.Y.Z`) is manual.** It lives in `internal/version/version.go`:

```go
const (
    Version = "0.2.1"  // ← bump this before a release
)
```

**The prerelease suffix is automatic:**

- **Beta**: `ci-develop.yml` auto-increments `beta.N` by counting existing `vX.Y.Z-beta.*` tags
- **Stable**: `ci-main.yml` uses the exact version from `version.go` (no suffix)

Binary version is injected at build time via `-ldflags`:

```bash
# Beta build (automatic in CI)
go build -ldflags="-X github.com/muyue/muyue/internal/version.Prerelease=beta.3" ./cmd/muyue/
# → muyue v0.2.1-beta.3

# Stable build (automatic in CI)
go build -ldflags="-s -w" ./cmd/muyue/
# → muyue v0.2.1
```

### Conventional commits

Use [Conventional Commits](https://www.conventionalcommits.org/) for all commit messages:

| Prefix | Use for | Example |
|--------|---------|---------|
| `feat:` | New feature | `feat: add Docker support` |
| `fix:` | Bug fix | `fix: correct config path on Windows` |
| `docs:` | Documentation | `docs: add API reference` |
| `chore:` | Maintenance | `chore: bump version to 0.3.0` |
| `refactor:` | Code restructuring | `refactor: split scanner module` |
| `perf:` | Performance | `perf: cache scanner results` |
| `test:` | Tests | `test: add config unit tests` |
| `ci:` | CI/CD changes | `ci: add beta release workflow` |
| `security:` | Security fixes | `security: encrypt API keys at rest` |

### Branch protection (configure in Gitea UI)

- **`main`**: Require PR + passing CI + at least 1 approval
- **`develop`**: Require PR + passing CI
- **Squash merge**: Enabled by default for PRs to `develop`
- **Merge commit**: For PRs from `develop` to `main`
