About this skill
Solve KCTF AntiAI and anti-analysis crackmes with fixed-length inputs, hidden state buffers, debugger checks, and staged integer recovery. Use for Windows executables that gate on a small state machine, checksum, or integrity path rather than a flat serial.

Workflow
- Record file type, bitness, entrypoint, imports, and the exact prompt/output strings.
- Check whether the binary hides validation in a state buffer, a helper section, or a debugger gate.
- Validate on:
- empty input
- wrong-length input
- one representative sample
- Recover the state transition before attempting brute force.
- Keep the raw input, state dump, and recovered output separate.
Use this pattern
- fixed-length input
IsDebuggerPresent/ integrity / anti-analysis checks- small hidden state vector
- final
yes/noorsuccess/failgate
