Reviews a V8 CL, commit, or local diff using targeted parallel subagents. Use when reviewing code changes in V8. Do not use for triaging bugs or authoring fixes.
Use this skill when designing, writing, or minimizing regression tests (e.g., mjsunit) for V8 bug fixes
Reproduces, heals (e.g., converting browser/HTML POCs to d8), minimizes, and classifies whether a V8 POC is a security vulnerability or a regular bug.
Guides the initial analysis and impact assessment of a V8 security report, strictly excluding implementation or fixing.
Manages git task isolation and environment setup in V8. Use at the start of any new task or bug fix. Do not use for general C++ editing.
Executes and interprets V8 tests. Use when running unittests, cctest, or mjsunit, or when debugging test failures. Do not use for building.
Runs and reports the checks that a change to experimental/redline must pass before upload. The checks cover formatting, lint, the build, the selftests, the parser round trip and the golden traces. They also cover the Markdown links, the ASD-STE100 language of…
Manages the V8 feature shipping lifecycle, including checking feature status and consistency in src/flags/feature-flags.h, advancing features through shipping steps (experimental, pre-stage, stage, ship), checking Finch studies, fieldtrial configs, Origin…
