desktop-release-gate

A rule for desktop application changes that requires local tests and, when relevant, a packaged Windows build and startup smoke test before release.

In plain words
What is it for?
Use it when changing an Electron or packaged desktop app, its Python backend, installer, tray behavior, or startup and update process.
Why use it?
It catches backend path, import, startup, tray, and user-interface problems before they reach release tags or users.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

desktop-release-gate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Desktop release gate (local first)

When fixing or changing the packaged OpenSquad desktop app (Electron, PyInstaller backend, tray/icons, startup, auto-update):

Required before push / tag / build-desktop CI

  1. Unit/smoke tests — run the ci-fast subset (ruff, targeted pytest, npm run build).
  2. Local backend build + frozen smokes (Windows; ~5 min + ~30 s):
    scripts\build_backend.bat
    uv run python scripts\smoke_frozen_all.py
    
    This catches import-time writes and workspace path bugs without waiting for Electron/Setup.
  3. Full packaged build when changing Electron/UI/installer (optional for backend-only fixes):
    cd src\opensquad\gateway\nexuschat-pro
    npm ci
    npm run electron:win
    
  4. Manual smoke test of the produced installer or portable exe (when shipping UI/installer changes):
    • App window shows UI (not blank / not stuck on “Starting…”)
    • Tray icon visible
    • No “Backend did not start in time” dialog
  5. Only then: commit → merge main → push tag or trigger build-desktop.yml.

Do not push a release tag or ask the user to install from CI as the first verification step for desktop startup/UI bugs.

Windows local build (mirrors CI)

From repo root:

pip install -e .
pip install pyinstaller pillow playwright
playwright install chromium

scripts\build_backend.bat

cd src\opensquad\gateway\nexuschat-pro
npm ci
npm run electron:win

Installers land in build/release/ (e.g. OpenSquad-*-win-x64-Setup.exe or *-Portable.exe). Run one and confirm the above smoke checks.

Faster iteration (code-only, not a release gate)

  • npm run build && node scripts/compile-electron.mjs — compile frontend + main process
  • npm run electron:dev:fast — needs pre-built backend in resources/ or build/backend-win/

Use full electron:win before any release/tag push.

CI after local pass

  • New release: merge to main, tag vX.Y.Z, push tag (triggers Release + Build Desktop App).
  • Refresh existing release assets: gh workflow run build-desktop.yml --ref main -f release_tag=vX.Y.Z

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

desktop-release-gate is a cursor rule published in the GitHub repository opensquad-ai/opensquad (5 stars, last pushed 19d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 609 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
