libfuzzer

Use this skill when the task matches the description above or the source path clearly applies. Start with this concise entrypoint; open ../../../../../skills/by-category/testing-qa-benchmarking/security-reference/libfuzzer/SKILL.md only when implementation details, commands, assets, or references are needed.

Workflow

1. Confirm the task matches this skill's scope.
2. Read the local source mirror if more detail is required.
3. Follow repository-level AGENTS.md; use one AI session only.
4. Keep claims tied to files, commands, citations, or benchmark artifacts.
