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 | $0.00976 | $0.00976 |
| Opus 5 | $0.00488 | $0.00488 |
| Sonnet 5 | $0.00195 | $0.00195 |
| Haiku 4.5 | $0.00098 | $0.00098 |
Grade A, and why
overview 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 4d 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.

Amarok Project Overview
Introduction
Amarok is a lightweight Android app that quickly hides files and applications — ideal for casual privacy needs. Instead of encryption, it manages file and app visibility using various techniques.
Core Features
- File Hiding: Obfuscation and Chmod modes.
- App Hiding: Supports Root, Shizuku, Dhizuku, and DSM modes.
- XHide Module: Uses Xposed to filter hidden apps from system queries.
- Panic Button: Floating button to trigger hide operations.
- Quick Settings Tile: Direct access for quick hide/unhide.
- App Lock: Protects with password/fingerprint.
Functional Index
1. Hiding Management
File: app/src/main/java/deltazero/amarok/Hider.java
The Hider class serves as the central management system for both file and app hiding operations.
- Retrieve State:
Hider.getState()returns one of three states:HIDDEN,VISIBLE,PROCESSING.
NOTE: Calling this method on a background thread does not guarantee that the latest value set will be received. Call it on the main thread.
- Trigger Processing:
Hider.hide(context)andHider.unhide(context)trigger hiding/unhiding operations.
2. File Hiding Implementations

4. Settings and Preferences
- Settings persistence is handled through the
PrefMgrclass (app/src/main/java/deltazero/amarok/PrefMgr.java) with SharedPreferences. - UI is implemented under
app/src/main/java/deltazero/amarok/ui/settings/with each setting grouped by category.
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.
- 4d ago First seen · 104 lines · 976 tokens per session scan A 13ee0745b9cc
overview is a cursor rule published in the GitHub repository deltazefiro/Amarok-Hider (3,226 stars, last pushed 23d ago), licensed Apache-2.0. It adds 976 tokens to every session, about $0.0049 per session on Opus 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.
