What problem does it solve?
This skill addresses the need for reliable, high-coverage fuzzing harnesses that can target code across multiple programming languages.
Core Features & Use Cases
- Harness design patterns for C/C++, Rust, and Go to route fuzzed inputs to the SUT.
- Structured input extraction using utilities like FuzzedDataProvider to produce typed data safely.
- Determinism and isolation by resetting global state and mocking I/O to ensure reproducible results across iterations.
- Use Case: When fuzzing a new library, create a minimal LLVMFuzzerTestOneInput harness that validates inputs and exercises core APIs.
Quick Start
Create a minimal harness with LLVMFuzzerTestOneInput, link with libFuzzer, and run with a small seed corpus to begin fuzzing.
