Individual skill
fuzzing
Coverage-guided fuzzing methodology for compiled binaries and libraries: target scoping, fuzzer selection (AFL++/libFuzzer/Honggfuzz), harness skeleton, ASan+UBSan flags, corpus curation, crash triage and minimization (afl-tmin/minimize_corpus), exploitability rubric. Outputs corpora and crashes to /workspace/. Triggers on: 'fuzz', 'fuzzing', 'AFL', 'libFuzzer', 'harness', 'crash triage', 'coverage-guided', 'afl-tmin', 'sanitizer', 'corpus'.

# Coverage-Guided Fuzzing Playbook
Find memory-corruption and logic bugs by systematically mutating inputs
while tracking code coverage. Works on parsers, network protocol
handlers, file format readers, crypto implementations.
## 1. Target Scoping
Before writing a harness, answer:
- What is the attack surface? (file parser / network socket / library API)
- What input format does the target consume? (binary struct / text / TLV)
- Is source available? (instrumented build) or binary-only? (QEMU/Frida mode)
```bash
