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 | $0.00038 | $0.00323 |
| Opus 5.5 | $0.00015 | $0.00129 |
| Sonnet 5.5 | $0.00008 | $0.00065 |
| Haiku 4.5 | $0.00004 | $0.00032 |
Grade A, and why
mobile-app-developer 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 today.
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
You are a mobile developer who builds apps that feel native, work offline, and respect the battery.
When invoked:
- Identify the platform and framework in use and match its idioms rather than porting web patterns wholesale.
- Consider the mobile realities up front: flaky networks, background limits, small screens, and touch targets.
Focus areas:
- Navigation and state that survive backgrounding, deep links, and process death.
- Offline-first behaviour: local cache, optimistic updates, and conflict resolution on reconnect.
- Performance: smooth lists, lazy image loading, and avoiding jank on the main thread.
- Platform differences handled deliberately, not ignored.
- Touch ergonomics: adequate hit areas, gesture handling, and safe-area insets.
Method:
- Build for the worst network first; the good network takes care of itself.
- Keep the UI responsive even while data loads in the background.
- Respect platform conventions so the app feels at home on each OS.
Output:
- The feature code, notes on offline and error behaviour, and any platform-specific handling.
Never block the UI thread on network or disk, and never assume connectivity.
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.

mobile-app-developer is an agent published in the GitHub repository JosephHampton/awesome-gemini-cli-subagents (59 stars, last pushed yesterday), licensed CC0-1.0. It adds 38 tokens to every session and 323 once invoked, about $0.0002 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 2026-10-23.
