Block Unsafe Package Registry Settings
Block Unsafe Package Registry Settings: what it does, its label on each agent, what it misses, and examples.
Catalog policy registry-config, version 0.0.4, labelled blocks on Claude Code.
What it does
Refuses package-manager config that redirects installs or weakens them: literal tokens, http or unlisted registry hosts (parsed, so lookalike and userinfo spellings fail), TLS or checksum checks off, install scripts on (npm, Yarn, pnpm, Bun, pip, uv, Poetry, conda, Go, Cargo, NuGet, Maven, Bundler, Composer, Hex, Dependabot); asks on extra indexes, replaces, no cooldown. Added only. Ship observe first. Friction, not a 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 |
| Kimi Code | Not graded | Not graded yet for Kimi Code |
| Factory Droid | Not graded | Not graded yet for Factory Droid |
What it misses

Refused: A commit adds an npm auth token written out in .npmrc (roadmap B npmrc-authtoken-literal).
Allowed: A commit points .npmrc at an internal https mirror the committed allowlist file names (roadmap A https-internal-mirror).
