## Skills

- perl: Use this skill for write and review Perl for deterministic runtime helpers, CLI tools, and data transforms with strict validation and minimal shell exposure. Use when the user asks about Perl code beyond hook-specific modules.
- runtime-config: Inspect rendered config, instruction rewrites, and home sync behavior.
- runtime-sandbox: Review Bubblewrap-backed Codex runtime isolation and ephemeral session state.
- schema-diff: Compare checked-in config against upstream schema and release snapshots.
- setup-audit: Audit installer behavior, rollout state, and verification coverage.
