What it does

Android Screenshots is an agent skill from boardsesh/boardsesh. Capture screenshots of the Boardsesh React Native app (packages/mobile/) running on an Android emulator, driven against Metro with a cached dev-client APK. Use when asked to screenshot / see / visually verify the mobile app on Android, or to share mobile screenshots in chat. Linux/KVM-friendly; the iOS counterpart is vp run mobile:ios-shots (full App Store matrix: vp run mobile:screenshots). Full reference: docs/android-emulator-screenshots.md.

Its SKILL.md is about 1.1k 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 Mobile, covering Cross-platform mobile apps, App store release and Mobile testing and debugging. It works with Android, iOS, React Native and Linux. The licence is Apache-2.0.

When your agent uses it

  • Asked to screenshot / see / visually verify the mobile app on Android
  • Share mobile screenshots in chat

Example prompts

  • “/android-screenshots”

What it can do on your machine

Read from SKILL.md and the folder at commit 340d1ea. 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:

    • adb

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

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SCREENSHOT_USER_PASSWORD

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Android Screenshots loads about 1.1k tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 480 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~118
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Capture screenshots of the Boardsesh React Native app (packages/mobile/) running on an Android emulator, driven against Metro with a cached dev-client APK. Use when asked to screenshot / see / visually verify the mobile app on Android, or to share mobile screenshots in chat. Linux/KVM-friendly; the iOS counterpart is `vp run mobile:ios-shots` (full App Store matrix: `vp run mobile:screenshots`). Full reference: docs/android-emulator-screenshots.md.

Android emulator screenshots

Boots a headless x86_64 emulator, installs a cached dev-client APK (no bundled JS — it loads from Metro), runs the app, and captures with adb exec-out screencap. The APK is built/downloaded once and reused; only the JS regenerates per run.

Workflow (preferred: boot once, shoot many)

  1. First run only — bootstrap. vp run mobile:android-doctor installs the Android SDK and a Temurin JDK 21 under ~/.cache/boardsesh/ (~2.5 GB, one-time) and reports KVM / JDK / AVD / cached-APK status. Skip on subsequent runs (the main command auto-bootstraps anyway).

  2. Pick login/data state:

    • Prod test account (default): export SCREENSHOT_USER_PASSWORD=<prod test pw> so the app auto-logs-in test@boardsesh.com and shows real content. Without it, the app stops on the login screen.
    • Local seeded data: run vp run dev first, then add --backend local (seeded test/test).
    • Plain app (drive login yourself): add --no-screenshot-mode.

  3. Boot in the BACKGROUND. The bare command holds Metro and blocks, so launch it with the Bash tool's run_in_background: true: vp run mobile:android-shots (plus --backend local / --no-screenshot-mode as chosen). It boots the emulator, installs the APK (downloads the universal rn-android-dev-* release or builds an x86_64 dev-client locally), starts Metro, adb reverse, and launches the app.

  4. Wait for "Ready". Poll the background task's output file (returned when you launched it) with a second run_in_background Bash until-loop so you get one notification: until grep -qE "Ready\. Emulator|FAILED|did not finish booting" <output-file>; do sleep 3; done

  5. Capture (foreground). For each screen: vp run mobile:android-shots -- screenshot --to <screen> --label <name> It navigates via deep link, captures, and prints the absolute PNG path. Screen names: home, climbs, board-view, board-sheet, discover, record, profile, session-detail, logbook — or pass a raw route, e.g. --to 'climbs?screenshotBoardIndex=1'.

  6. Share. SendUserFile each printed PNG path.

  7. Stop when done. vp run mobile:android-shots -- shutdown (kills emulator + Metro), and stop the backgrounded boot task.

One-shot alternative (simplest, slower per shot)

vp run mobile:android-shots -- --to climbs --label climbs --shutdown — boots, captures one screen, tears down, and exits in a single (long) foreground call. No emulator reuse, so prefer the background workflow for multiple shots.

Useful flags & env

  • --flow app-store|onboarding runs the committed Maestro flows instead of ad-hoc capture.
  • --app-path <apk> / --apk-tag <tag> / --build-local to control APK resolution.
  • Env: BOARDSESH_EMULATOR_GPU (renderer), BOARDSESH_AVD_NAME, BOARDSESH_EMULATOR_BOOT_TIMEOUT, BOARDSESH_METRO_PORT. See docs/android-emulator-screenshots.md for the full table.

Requirements & troubleshooting

  • Needs a host with /dev/kvm (fast emulation) and a working software GPU renderer. On normal dev machines and standard CI (GitHub Actions ubuntu-latest, used by the repo's Android screenshot job) swiftshader_indirect works out of the box.
  • Emulator exits immediately / "did not finish booting": check .boardsesh/android-emulator.log. If the renderer segfaults, some heavily-sandboxed or exotic-CPU VMs can't run the emulator's software GPU at all — there's no software-only fallback; run on a normal host/CI. If running inside a sandboxed agent environment and qemu dies instantly, the Bash sandbox may be blocking its KVM/memory syscalls — retry the boot with the sandbox disabled.
  • Screenshots land in .boardsesh/android-screenshots/NN-<label>.png (gitignored).
