# Validate pstack contracts Run the bundled validator rather than inspecting pstack artifacts by eye. The CLI enforces the same contract rules as the upstream native tools; Codex has no native validator tool and does not need one. ## Commands Resolve `scripts/validate.mjs` relative to this skill directory. Keep the working directory at the approved workspace. Inputs must be regular files inside that workspace, without traversal, URLs or symlink components. Confined validation requires macOS or Linux and fails closed on other platforms. Artifact evidence references are validated as data, never read or executed. ```sh node scripts/validate.mjs snapshot <snapshot.json> node scripts/validate.mjs receipt <receipt.json> node scripts/validate.mjs handoff <handoff.json> node scripts/validate.mjs plan <plan.md> [basic|verified-stack] ``` The command exits `0` on success, `1` for contract violations, and `2` for invalid invocation or unreadable input. Report every finding with its path or line number. Malformed JSON is an input error. Do not reinterpret a failed contract as a warning.
