Run a Codex-CLI static-analysis parity review of the current diff against the local RPython/PyPy sources, then act on it — fix the regressions and new mismatches in-session, and file the rest as follow-up tasks. Invoked via `/codex-review`. Use this skill at the END of a work cycle, or whenever the user asks to "run codex review", "codex 리뷰 돌려줘", "리뷰 사이클 돌려줘", "parity review with codex", "check this diff against RPython with codex", or any request to have Codex audit the current changes for RPython/PyPy porting fidelity. Reach for it any time the user wants a Codex-driven parity pass over the working diff, even if they don't say the exact word "codex-review".

Plan and execute a safe merge of the current working branch into `upstream/main` by accumulating only green-test changes onto a separate `<branch>-merge` branch. Invoked via `/merge`. Use this skill whenever the user asks to "merge", "land", "prepare for merge", "cherry-pick safely", or any equivalent request to move work from a long-running branch toward `upstream/main`. The skill enforces the house policy that `pyre/check.py` must be all green, and it prefers line-level imports over whole-commit cherry-picks (bare `git cherry-pick` is only safe for trivially conflict-free, self-contained commits). Default to using this skill any time the user hints at moving work from a long-running branch toward `upstream/main`, even without explicit keywords.

Enforce strict line-by-line RPython/PyPy structural parity for changes in the majit/pyre codebase. Invoked via `/parity`, usually combined with a follow-up task (e.g. `/parity continue

Rebase the current working branch onto `upstream/main` (the remote base, NOT local `main`), resolving every conflict by consulting the authoritative RPython/PyPy source under `` rather than arbitrarily picking a side. Invoked via `/rebase`. Use whenever the user asks to "rebase", "rebase onto main", "restack on main", "replay on top of main", "pull main under my branch", or any equivalent request to rewrite the current branch on top of main while resolving conflicts. Before rebasing, this skill commits any unstaged work and squashes WIP noise into concise commits. During rebase, conflicts are resolved per-hunk — commit-level granularity is explicitly too coarse; each conflicting region is judged individually against upstream RPython/PyPy and merged to the more RPython-orthodox shape. Default to using this skill any time the user mentions rebasing, pulling main under the branch, or conflict resolution in the context of a long-running branch. Complements but does not replace `/merge` (which builds a green `-mer
