# GitHub Outside Sandbox

1. Start normally. Escalate only the blocked command and only within the user's authorization.
2. If sandboxed `gh auth status` fails, rerun it outside the sandbox before claiming authentication is broken. Never expose or copy tokens.
3. Run GitHub CLI network operations outside the sandbox when required: `gh repo ...`, `gh pr ...`, and related `gh` commands.
4. Run Git writes outside the sandbox when `.git` is outside writable roots or errors mention `index.lock` or `Operation not permitted`: `git add`, `git commit`, and `git push`.
5. Use the harness's official host-execution mechanism. In Codex, set `sandbox_permissions: "require_escalated"`, give a concrete `justification`, and use only a narrow safe `prefix_rule` when appropriate.
6. Never use shell wrappers, credential copying, or broad approval prefixes to bypass the sandbox.
7. Verify from the host context with `git status -sb`, `git remote -v`, and the relevant `gh ... view` command. Ask the user to authenticate only if the host-context check also fails.
