coverage-analysis

The agent uses coverage analysis to measure which code paths, branches, and functions are exercised during fuzzing campaigns. It generates LLVM and GCC coverage reports, identifies uncovered code blocks, detects magic value checks that block fuzzer progress, and tracks coverage trends over time. The agent applies this technique when assessing harness effectiveness, diagnosing coverage plateaus, comparing differential coverage between campaigns, or integrating coverage instrumentation into CMake and Rust builds using llvm-cov, gcovr, and cargo-fuzz coverage toolchains.
