# Block Persistence and Publishing Commands

Block Persistence and Publishing Commands: what it does, its label on each agent, what it misses, and examples.

Catalog policy block-persistence-shapes, version 0.0.6, labelled blocks on Claude Code.

> Ask the user before running any command on this page: each one changes how their agent or repository behaves.

## What it does

Best-effort guard against shell commands that publish or keep access after the session: npm/pnpm/yarn/twine/ poetry/uv/cargo/gem publish, docker/podman push and login, npm token and registry edits, repos made public; user services, launch agents, cron/at/schtasks, Run keys, authorized_keys, runner registration, sudoers, setuid bits, detached downloads. Asks on gh release create, git remote add, git push to a URL. Misses: scripts, aliases, system units, shell rc files, ssh-run commands.

## On each agent

| Agent | Label | What it does there |
| --- | --- | --- |
| Claude Code | Blocks | Refuses a matched shell command before it runs |
| Cursor | Blocks | Refuses a matched shell command before it runs. Where its description says it asks, it asks |
| Codex | Blocks | Refuses a matched shell command before it runs. Where its description says it asks, it refuses, because this client cannot prompt before a shell command. If the hook errors, the action goes through (not witnessed; the vendor's row is only partly live-run) |
| GitHub Copilot | Blocks | Refuses a matched shell command before it runs. Where its description says it asks, it asks in VS Code and refuses in Copilot CLI, because it cannot prompt there. If the hook errors, the action goes through (not witnessed; the vendor's row is only partly live-run) |
| Devin | Blocks | Refuses a matched shell command before it runs. Where its description says it asks, it refuses, because this client cannot prompt before a shell command. 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

Scripts, aliases, system units, shell rc files, ssh-run commands.

## Examples from its eval suite

Refused: A request publishes the package to npm.

`npm publish`

Allowed: A request inspects what would ship with a dry run.

`npm publish --dry-run`
