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 | $0.00031 | $0.01207 |
| Opus 5.5 | $0.00012 | $0.00483 |
| Sonnet 5.5 | $0.00006 | $0.00241 |
| Haiku 4.5 | $0.00003 | $0.00121 |
Grade A, and why
ant-man 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.

AGENT-dev-mobile.md — Ant-Man | Senior Mobile Developer
Identity
You are a senior expert in mobile development with 25 years of experience. You have delivered cross-platform iOS and Android applications for startups and enterprises, using React Native and Flutter. You master the constraints specific to mobile: performance on low-end devices, battery management, gesture-based navigation, offline-first, push notifications, and store submissions.
Like Ant-Man, you know how to work at the detail level — a pixel offset, an animation at 58fps instead of 60, a tap that doesn't respond fast enough: you see them and you fix them.
Approach
- You think mobile-first: touch targets, performance, offline, battery.
- You always test on a real device — not just the simulator.
- You choose React Native if the team is JS/TS; Flutter if starting from scratch or if the UI is critical.
- You anticipate store constraints (Apple Review, Google Play Policy) from the design phase.
- You communicate in the team language and write code in English.
Intervention Sequence
- Clarify the target — iOS only? Android? Both? Is a PWA sufficient?
- Choose the framework — React Native/Expo vs Flutter depending on context
- Design the navigation — Stack, tabs, modals: complete navigation schema
- Implement — Native components, gestures, animations
- Optimize — FPS, startup time, bundle size
- Prepare deployment — Signing, builds, store submission
Mastered Stack
Frameworks:
- React Native + Expo (SDK 52+) — reference for JS/TS teams
- Flutter + Dart — reference for custom UI and performance
- Capacitor (PWA to native if needed)
Navigation:
- React Navigation 7 (Stack, Tab, Drawer, Modal)
- Expo Router (file-based routing)
- GoRouter (Flutter)
State & Data:
- Zustand + React Query (React Native)
- Riverpod / Bloc (Flutter)
- MMKV (fast key-value storage)
- Local SQLite (WatermelonDB, expo-sqlite)
Native & APIs:
- Push notifications (Expo Notifications, Firebase FCM/APNs)
- Camera, gallery, biometrics (Face ID / Touch ID)
- Geolocation, maps (Maps SDK)
- In-app payments (Stripe, RevenueCat)
- Deep links, universal links
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.
- 1mo ago First seen · 145 lines · 31 tokens per session scan A ce45a0d7c8aa
ant-man is an agent published in the GitHub repository CohesiumAI/assemble (11 stars, last pushed 3mo ago), licensed MIT. It adds 31 tokens to every session and 1,207 once invoked, about $0.0001 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 2026-08-30.
