Lockfile Integrity
Lockfile Integrity: what it does, its label on each agent, what it misses, and examples.
Catalog policy lockfile-integrity, version 0.0.3, labelled blocks on Claude Code.
What it does
Script gate (commit, agent write, CI) over npm, yarn, pnpm, bun, poetry, uv, Pipfile, Cargo, go.sum, Gemfile, composer and NuGet locks. Blocks: source off the registry list or not https, missing hash, hash changed for a locked version, unpinned git source, unreadable lock. Asks: SHA-1-only hash, transitive install script, lock or manifest moved alone, go.sum lines removed, lock ignored or deleted. Judges what a change adds. Friction, not a security boundary.
On each agent
| Agent | Label | What it does there |
|---|---|---|
| Claude Code | Blocks | Blocks on an agent's file writes and at turn end |
| Cursor | Blocks | Blocks on an agent's file writes and at turn end. Where its description says it asks, it refuses at both points, because this client cannot prompt at either point |
| Codex | Blocks | Blocks on an agent's file writes and at turn end. Where its description says it asks, it refuses at both points, because this client cannot prompt at either point. If the hook errors, the action goes through (not witnessed; the vendor's row is only partly live-run) |
| GitHub Copilot | Blocks | Blocks at turn end only. It does not check a file write when it happens. Where its description says it asks, it refuses at turn end, because this client cannot prompt there. If the hook errors, the action goes through (not witnessed; the vendor's row is only partly live-run) |
| Devin | Blocks | Blocks at turn end only. It does not check a file write when it happens. Where its description says it asks, it refuses at turn end, because this client cannot prompt there. If the hook errors, the action goes through (vendor docs only, not witnessed) |
| Grok | Not graded | Not graded yet for Grok |
| goose | Not graded | Not graded yet for goose |
| Antigravity | Not graded | Not graded yet for Antigravity |
| OpenHands | Not graded | Not graded yet for OpenHands |

What it misses
This policy does not state what it misses.
Examples from its eval suite
Refused: A commit keeps [email protected] but points its resolved URL at another host.
Allowed: A commit bumps left-pad to 1.3.1 in package.json and the lock, with a registry URL and sha512.
