Desktop Brand Builder

Goal

Create a branded desktop package with the least user input possible. The user should usually provide only:

brandId: acme-ai
logo: /absolute/path/to/logo.png
website: https://acme.ai

website is optional. Do not ask for app name, app id, artifact name, copyright, dock icon, renderer symbol, signing, or local installation unless the user explicitly asks to override them.

Input Rules

Required fields:

• brandId: must match ^[a-z][a-z0-9-]*$
• logo: local file path; must exist

Optional overrides:

• website
• appName
• appId
• artifactPrefix
• target: mac, win, linux, or all

If required input is missing, ask once:

请提供：
brandId: 例如 acme-ai，只能小写字母、数字、短横线
logo: 本地 logo 文件路径
website: 可选

Once the required fields are present, proceed without a confirmation step.

Derived Defaults

Infer missing values deterministically:

• appName: title-case the hyphen-separated brandId; acme-ai becomes Acme AI
• artifactPrefix: title-case the hyphen-separated brandId and join with hyphens; acme-ai becomes Acme-AI
• appId: if website has a valid host, reverse the host labels and append .desktop; https://acme.ai becomes ai.acme.desktop
• fallback appId: app.<brandId>.desktop
• copyright: Copyright © <current year> <appName>
• all brand images: generate icon, dock icon, and renderer symbol from logo

Use explicit user-provided override values as-is after basic validation.

Build Workflow

Use an isolated build directory under the current working directory so user changes in the current worktree are not mutated. Default to the qwen-code main branch; do not clone from craft-agents-oss, OpenWork, or another local checkout unless the user explicitly asks for that source:

BUILD_ROOT="$PWD/brand-builds/<brandId>-<timestamp>"
mkdir -p "$BUILD_ROOT"
git clone --branch main --single-branch \
  https://github.com/QwenLM/qwen-code.git \
  "$BUILD_ROOT/qwen-code"
cd "$BUILD_ROOT/qwen-code"
git checkout -B brand-<brandId> origin/main

If the branch fetch or checkout fails, stop and report the failure. Do not continue as if brand-<brandId> was created.

Create a temporary brand.json in the build directory:

{
  "brandId": "acme-ai",
  "logo": "/absolute/path/to/logo.png",
  "website": "https://acme.ai",
  "appName": "Acme AI",
  "appId": "ai.acme.desktop",
  "artifactPrefix": "Acme-AI",
  "copyright": "Copyright © 2026 Acme AI"
}

Install desktop dependencies if packages/desktop/node_modules is missing:

cd packages/desktop
bun install

Then run this skill's bundled brand creation script:

cd /absolute/path/to/qwen-code
bun run packages/desktop/.agents/skills/desktop-brand-builder/scripts/brand-create.ts \
  --desktop-root /absolute/path/to/qwen-code/packages/desktop \
  --config /absolute/path/to/brand.json

The agent should not hand-edit branding.ts or brand asset files when this bundled script is available. The bundled script is the source of truth for patching code and generating resources.

Package with the current host target unless the user requested a target:

CRAFT_BRAND=<brandId> bun run electron:dist:mac
CRAFT_BRAND=<brandId> bun run electron:dist:win
CRAFT_BRAND=<brandId> bun run electron:dist:linux

For target: all, run only targets supported by the current machine or CI environment. Do not claim cross-platform artifacts were produced unless the files exist.

Validation

After packaging:

1. Confirm the expected artifact exists under packages/desktop/apps/electron/release/.
2. Compute sha256sum or shasum -a 256 for each artifact.
3. On macOS, run hdiutil verify for generated DMG files.
4. Report the artifact path, SHA-256, app name, app id, and build directory.

Failure Handling

• Invalid brandId: show the regex and ask for a corrected value.
• Missing logo: ask for a valid local path.
• Missing bundled script: report that packages/desktop/.agents/skills/desktop-brand-builder/scripts/brand-create.ts is missing, and include the expected command.
• Build failure: preserve the build directory, return the last useful error lines, and include the full log path or command that produced the failure.

Do not delete the build directory on failure.
