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 | $0.00105 | $0.00607 |
| Opus 5 | $0.00053 | $0.00303 |
| Sonnet 5 | $0.00021 | $0.00121 |
| Haiku 4.5 | $0.00011 | $0.00061 |
Grade A, and why
competition-crypto-mobile 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 9d 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-crypto-mobile — 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 Crypto Mobile
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 active challenge depends on recovering a transform chain, hidden media payload, mobile signing path, or local trust boundary.
Reply in Simplified Chinese unless the user explicitly requests English.
Quick Start
- Decide whether the dominant path is crypto, stego, or mobile.
- Recover transforms in order; do not jump straight to the fanciest algorithm.
- Record exact parameters and boundaries that affect the result.
- Hook the narrowest mobile boundary that proves the behavior.
- Reproduce the plaintext, payload, signed request, or accepted branch.
Workflow
1. Crypto And Encoding
- Reconstruct the chain step by step: container, compression, encoding, xor or substitution, crypto, integrity, final parse.
- Keep exact keys, IVs, nonces, salts, tags, offsets, and byte order.
2. Stego
- Inspect metadata, chunk layout, palettes, alpha planes, LSBs, thumbnails, trailers, and transcoding artifacts.
- Rank decode attempts by evidence, not by brute-force curiosity.
3. Mobile
- Start with manifest or plist, exported components, deeplinks, native libs, shared prefs, local DBs, and configs.
- Trace signer logic, token storage, SSL pinning, protobuf or RPC boundaries, and native bridge calls.
Read This Reference
- Load
references/crypto-mobile.mdfor the transform checklist, hook targets, and evidence packaging. - If the task is specifically about Android dynamic tracing, signer hooks, JNI boundaries, or pinning checks, prefer
$competition-android-hooking. - If the task is specifically about iOS runtime tracing, Keychain access, Objective-C or Swift hooks, or pinning checks inside an IPA, prefer
$competition-ios-runtime. - If the task is specifically about media carriers, hidden channels, thumbnails, or appended trailers, prefer
$competition-stego-media.
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-crypto-mobile is a skill published in the GitHub repository Saprophytic-seattle561/reverse-skill (1 stars, last pushed 2d ago), licensed MIT. It adds 105 tokens to every session and 607 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to competition-crypto-mobile, differing in 0 lines, and is treated as a copy.
