[codex] Add Codex environment setup by pranaygp · Pull Request #2238 · vercel/workflow

pranaygp · 2026-06-03T23:54:12Z

Description

Add a checked-in Codex environment descriptor so Codex tasks bootstrap the workspace with pnpm install --frozen-lockfile.

This keeps environment setup deterministic from the committed lockfile and avoids coupling the bootstrap step to app credentials or target-specific builds. An empty changeset is included because this is internal configuration and does not change a published package.

How did you test your changes?

Parsed .codex/environments/environment.toml with Python tomllib.
Ran git diff --check origin/main...HEAD.
Verified the signed, signed-off commit is reported as valid by GitHub.
