What it does

Window Simulator is an agent skill from naveedharri/baalda. Run Baalda's real desktop UI in a local browser with synthetic vault data to preview Windows or macOS layouts, investigate visual bugs, and capture screenshots from a Mac. Use for browser UI simulation; native window behavior still requires the target OS.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Knowledge Management, covering Second brain. It works with macOS. The repository describes itself as: The team second brain. Plain Markdown files on your disk, edited together in real time, and read and written by your AI like a teammate. The licence is Apache-2.0.

When your agent uses it

  • Browser UI simulation
  • Native window behavior still requires the target OS

Example prompts

  • “/window-simulator”

What it can do on your machine

Read from SKILL.md and the folder at commit 2e988ad. 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

    Shell commands in SKILL.md call:

    • pnpm
    • cargo

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    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

Window Simulator loads about 1.2k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 614 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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); files beside SKILL.md are not scanned.

Run Baalda's real desktop UI in a local browser with synthetic vault data to preview Windows or macOS layouts, investigate visual bugs, and capture screenshots from a Mac. Use for browser UI simulation; native window behavior still requires the target OS.

Window simulator

Use the tracked harness in app/apps/desktop/dev/window-simulator/. It imports the real React app, styles, and editor after installing Tauri IPC and server mocks. Both platform modes use the same synthetic vault and members so missing fixture data cannot masquerade as a platform difference.

Start on a Mac

Resolve paths from this Baalda checkout. Read AGENTS.md and CLAUDE.md before changing product code. Install dependencies with pnpm install in app/ if needed.

From app/apps/desktop/:

bash
pnpm run simulate:windows
# Or, for the macOS layout:
pnpm run simulate:macos

The simulator uses port 1425, separate from Tauri development on 1420. Once the server is running, reuse it for both URLs:

  • Windows: http://localhost:1425/dev/window-simulator/?platform=windows
  • macOS: http://localhost:1425/dev/window-simulator/?platform=macos
  • Add &theme=dark or &sidebarHidden=true for those states.

Keep the Vite process/session handle for logs and cleanup. If the port is busy, check whether this checkout's simulator is already serving there; do not stop an unrelated process or launch a second server needlessly. A browser reload resets the fixture's in-memory changes.

Preview and investigate

Use available browser tooling to open the real simulator URL. For a large review screenshot use a 1600×1000 viewport; also inspect 720×600 when changing window chrome or panel layout. Compare Windows and macOS with the same theme, viewport, sidebar state, and selected note. A macOS browser simulation cannot draw the operating system's actual traffic lights. The platform parameter selects the app's platform branch; it does not change the browser engine into WebView2 or WKWebView.

Navigate the surfaces affected by the change. For titlebar work, include the sidebar shown/hidden, the Activity/Versions panel, graph, welcome screen, and settings overlays. On Windows, opening the Activity/Versions panel hides the window caption controls; its own close button stays at the top edge. Closing the panel restores the caption controls. For avatars, inspect a vault icon and several character avatars in the same document: shared SVG resource IDs can fail in the full app even when an isolated gallery renders correctly.

If a panel is unexpectedly empty or an action is missing, inspect the mock response and the consuming API type before blaming the platform. The harness must return complete, correctly shaped data for the surface being reviewed. For example, /api/auth-methods controls the bug-report button, member roles control manager actions, and a public link requires a real-shaped url field. Add missing synthetic responses in the harness rather than changing production authorization or visibility rules to make a preview appear populated. Keep the fake API session and UI store in agreement: profile saves re-read the session, and seeding only the visible signed-in state produces a false sign-out when the client has no demo token.

Show full SKILL.md (196 more words)Show less

The harness is development-only. Keep sample identities, links, and credentials obviously synthetic. Preserve mocked IPC/network boundaries; do not connect the simulator to a real vault, account, database, or model provider. Preview actions must not send email, publish notes, change access on a real server, or make payments. Do not save real credentials in fixtures or screenshots.

Verify and hand off

Follow the current task's testing arrangement. If the user wants visual review before a single final testing pass, finish the preview edits and wait for that review before starting the pass. Relevant product tests, type checking, and a Windows-target frontend build remain separate from the browser simulation:

bash
# From app/apps/desktop; select tests appropriate to the actual change.
pnpm exec vitest run <test-files>
pnpm exec tsc --noEmit
TAURI_ENV_PLATFORM=windows pnpm run build

Save screenshots in an ignored artifacts.local/ directory or an OS temporary directory, never alongside tracked fixtures. Show the user the screenshot and the live URL, and leave the simulator running when it is the requested preview. Keep the user's latest reviewed layout in the deliverable tab.

Report browser checks as simulation checks. Native Windows drag, resize, Snap, DPI scaling, WebView2-specific behavior, caption commands, and packaged CSP need appropriate native validation; macOS cargo check does not compile Windows-only Rust branches. This workflow needs neither a backend nor destructive server tests.

Can I use Window Simulator in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add naveedharri/baalda --skill window-simulator -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/window-simulator, .gemini/skills/window-simulator, .github/skills/window-simulator and .opencode/skills/window-simulator in your project.

What does Window Simulator need to run?

Going by SKILL.md and its folder, Window Simulator needs the command-line tools its instructions call (pnpm and cargo).

Does Window Simulator access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
