Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for crypto, encoding, steganography, APK, IPA, and mobile trust-boundary challenges. Use when the user asks to decode a blob, recover a transform chain or key, inspect hidden media payloads, hook an APK or IPA signer, inspect app storage, or replay mobile request-signing logic. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

# 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

1. Decide whether the dominant path is crypto, stego, or mobile.
2. Recover transforms in order; do not jump straight to the fanciest algorithm.
3. Record exact parameters and boundaries that affect the result.
4. Hook the narrowest mobile boundary that proves the behavior.
