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 | $0.00114 | $0.00658 |
| Opus 5.5 | $0.00046 | $0.00263 |
| Sonnet 5.5 | $0.00023 | $0.00132 |
| Haiku 4.5 | $0.00011 | $0.00066 |
Grade A, and why
competition-android-hooking 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.
This is a copy
100% identical to competition-android-hooking — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Competition Android Hooking
Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.
Use this skill when the decisive path runs through an Android app's live trust boundary rather than static strings alone.

Quick Start
- Preserve the original APK, extracted resources, and decompiled output before patching or resigning.
- Start with manifest, exported components, deeplinks, native libs, prefs, local DBs, and bundled configs.
- Decide the narrowest runtime boundary to hook: signer, crypto helper, JNI bridge, WebView bridge, or request builder.
- Correlate static evidence and dynamic traces before claiming a trust edge is understood.
- Reproduce the signed request, accepted token, or gated branch from the smallest hook set.
Workflow
1. Static Triage Before Hooks
- Map package structure, exported activities, services, receivers, providers, and deeplink handlers.
- Note SSL pinning logic, root checks, feature flags, token storage, shared prefs, SQLite tables, and protobuf or RPC boundaries.
- Identify whether the sensitive logic sits in Java, Kotlin, JNI, or a bundled WebView.
2. Hook The Narrowest Boundary
- Prefer hooking request signers, crypto helpers, keystore access, protobuf encode or decode, or JNI marshaling instead of broad UI hooks.
- Record plaintext inputs, signed strings, headers, nonces, and outputs at the boundary that actually changes trust.
- If pinning or environment checks block progress, patch or hook only enough to expose the real request path.
3. Replay The Accepted Path
- Rebuild the smallest sequence that reaches the accepted server-side branch: local state, nonce, request body, signature, and headers.
- Keep hook logs, captured request shapes, and local storage paths tied to the same account or session state.
- If the challenge becomes more about transform recovery than Android runtime, switch back to the broader crypto or mobile skill.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

competition-android-hooking is a skill published in the GitHub repository Asaiuta/reverse-workbench-skill (4 stars, last pushed 2mo ago), licensed MIT. It adds 114 tokens to every session and 658 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to competition-android-hooking, differing in 0 lines, and is treated as a copy.
