Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00201 | $0.04038 |
| Opus 5.5 | $0.00080 | $0.01615 |
| Sonnet 5.5 | $0.00040 | $0.00808 |
| Haiku 4.5 | $0.00020 | $0.00404 |
Grade A, and why
android-emulator 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Android emulator (Flutter)
A bash helper that wraps adb and the qemu emulator console so an AI agent can see (screenshots, accessibility tree) and act on (tap, long-press, swipe, pinch) a Flutter app running on an Android emulator. Computer-use APIs cannot reach the emulator window (qemu has no macOS app bundle), and adb shell input is single-touch only — this script bridges both gaps.
When to use this
The user wants to launch, debug, smoke-test, QA, or screenshot a Flutter app on Android. Reach for this skill before resorting to coordinate-guessing, manual screenshotting via DevTools, or asking the user to run flutter run themselves.
Setup
The script assumes a working Android SDK install (with adb and emulator on $PATH or in ~/Library/Android/sdk/ / ~/Android/Sdk/), at least one AVD created, and Flutter (or fvm) installed. macOS-only utility: sips (used to resample screenshots — ships with macOS). On Linux, swap in convert from ImageMagick if porting.
The script is at scripts/emu.sh relative to this skill. Once the skill is wired into your project (see README.md), agents call it with that relative path.
Quick start (cold boot to interactive)
scripts/emu.sh boot # start an AVD (cold boot), idempotent
scripts/emu.sh run # flutter build & install in background (~30–60s first time)
scripts/emu.sh wait-run # blocks until attached or errors (180s timeout)
scripts/emu.sh health # sanity check
scripts/emu.sh ui-list # see what's on screen — start here, not screenshot
run auto-detects the project root (walks up to find pubspec.yaml) and uses fvm flutter if the project pins it. Always pair run with wait-run instead of sleep — the daemon's stdin is gone, so timing is the only signal that the build finished.
Commands
Emulator lifecycle
| Command | What it does |
|---|---|
boot |
Start the AVD in cold boot (-no-snapshot-load) and block until sys.boot_completed. Idempotent — if the device is already online, returns immediately. AVD defaults to the first one listed by emulator -list-avds; pin with ANDROID_EMU_AVD. |
exit |
Shut down the running emulator via the qemu console (kill). |
health |
One-shot status: connection, AVD name, resolution, foreground app, detected project root, detected package, flutter log size. Run this first to orient. Exits non-zero if the device isn't connected. |
devices / size / foreground |
Raw adb devices / wm size / focused activity. |
app-running |
Exit 0 if the target package is the focused app, 1 otherwise. Use in scripts. |

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.

android-emulator is a skill published in the GitHub repository ChunkyTofuStudios/flutter-skills (5 stars, last pushed 5mo ago), licensed MIT. It adds 201 tokens to every session and 4,038 once invoked, about $0.0008 per session on Opus 5.5. 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.
