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 | $0.00000 | $0.00476 |
| Opus 5 | $0.00000 | $0.00238 |
| Sonnet 5 | $0.00000 | $0.00095 |
| Haiku 4.5 | $0.00000 | $0.00048 |
Grade A, and why
add-app-logo 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 8d 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.
What it actually says
add-app-logo
Sets the launcher icon for one app under apps/{app}/ on Android, iOS,
and web from a single brand image, using flutter_launcher_icons.
How to run this skill:
- Pick the app — if not passed as an argument, list
apps/and ask. - Ask the user for their logo image if none was provided — SVG preferred,
or PNG ≥1024×1024. Put the original in
apps/{app}/assets/icons/. - Prepare the two 1024×1024 source PNGs (the tool takes PNG only):
app_icon.png(full-bleed, opaque — glyph at ~70%) andapp_icon_foreground.png(transparent, glyph inside the ~66% adaptive safe zone). Rasterise SVGs with headless Chrome; resize PNGs withsips. - Add
flutter_launcher_iconsto the app'sdev_dependencies(nevercore) plus the config block — includeremove_alpha_ios: true(the App Store rejects alpha in the 1024 icon) and the adaptive background/foreground pair. - Generate:
flutter pub getat the repo root, then from the app folderdart run flutter_launcher_icons. - Walk the verification checklist in the guide below — Android mipmaps +
mipmap-anydpi-v26/ic_launcher.xml+values/colors.xml; every iOSAppIcon.appiconsetsize with the 1024 icon alpha-free (filesays RGB); web icons + favicon. Report ✅/❌ per item. Also check the display name under the icon starts uppercase — flutter create seeds the lowercase package name intoandroid:label, iOSCFBundleName(DisplayName too),web/manifest.jsonname/short_name, andweb/index.htmltitle +apple-mobile-web-app-title. Fix all of them. - Device check: uninstall the old build first (launchers cache icons), then confirm on both platforms.

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.

add-app-logo is a skill published in the GitHub repository abhinav503/flutter-agentic (10 stars, last pushed 15d ago), licensed MIT.
