That destroys the sandbox. Offer instead to create a **new** +sandbox with a different `--name` and the desired kit set, and never remove the +existing one without explicit user consent. + +Warnings printed after a successful swap (read them; live success is not the +whole story): + +- Credentials the new kit set withheld because no binding exists; the sandbox + cannot authenticate against those services until a binding is added. +- Runtime `sbx mount` entries that failed to replay; re-run each listed + `sbx mount`, except entries marked permanent, for which the record must be + dropped. +- "record could not be saved": the sandbox runs with the new kit set but a + daemon restart would revert it.

The built-in - `devin` kit uses this mode. Review the agent's credential configuration - before promising that it cannot read a token; do not enable passthrough - merely to bypass an authentication failure. Even with sentinels, the - agent can exercise the credential's permissions on allowed services — - restrict token privileges as well as network access. -- Service secrets are global by default; `--sandbox NAME` scopes one to a - single sandbox. -- **Dynamic secrets** resolve the value on the host at use time instead of - storing it directly: `--ref` (1Password `op://...` or an AWS Secrets - Manager ARN — requires an authenticated `op`/`aws` CLI) or `--command` - (runs a shell command and uses its stdout). `--refresh` controls the - resolution/cache policy (default `55m`, or `on-demand`). + **Storing a secret does not grant network access.** Check the target domain in the intended scope before debugging authentication: `sbx policy check network --sandbox my-sandbox api.anthropic.com`. +- **OAuth passthrough gives no token-less guarantee.** When a kit sets `oauth.passthrough: true` without a refresh sentinel, the proxy forwards the real token response to the sandbox; the built-in `devin` kit does this. Check the kit's OAuth configuration before saying an agent cannot read a token, and do not enable passthrough to bypass an authentication failure. Even with sentinels the agent can use the credential's permissions on allowed services: restrict token privileges too. +- Service secrets are global by default; `--sandbox NAME` scopes one and takes precedence over the global secret, so removing the scoped one can expose the global one again. `--oauth` is openai/global only. +- Host environment variables never auto-inject: a secret reaches sandboxes only after `sbx secret set` or `sbx secret import` stored it. +- Third-party kits need an approved credential binding; built-in kits do not.

Use - `sbx secret set` (or `sbxenv.yaml`'s `secrets:`/`registries:` blocks, which - route through the same store) instead. -- `sbx secret set-custom` (experimental) covers a service sbx has no - built-in support for: the sandbox sees a placeholder value in an env var - you name (`--env`), and the proxy swaps in the real secret only on - requests to the `--host` pattern(s) you declare. -- `sbx secret ls [--global|--sandbox NAME] [--service NAME] [--json]` lists - what is stored, without revealing values. `sbx secret rm [SERVICE] - [--sandbox NAME] [--all|--registry HOST] [--force]` removes it. -- `sbx secret import [SERVICE] [--all] [--dry-run] [--force]` offers to - import secrets already sitting in host environment variables (e.g. - `OPENAI_API_KEY`, `GH_TOKEN`) into the global store, prompting per entry - unless `--all`/`--force`. A service with an OAuth token already configured - is skipped — OAuth takes precedence at runtime over an imported API key. +- **Never treat host helper execution as harmless.** The source runs with the user's host privileges at registration-time verification and at every refresh, from a **fresh temporary directory** (v0.46.0): `./helper` or a bare script name does not resolve against the project. Use an absolute helper path or a helper on an absolute `PATH` directory. +- Keep the helper, everything it loads, the host temporary directory and `PATH` entries outside writable sandbox mounts, including mounts added later with `sbx mount`. sbx does not copy, inspect or confine helpers; a fresh working directory is not confinement. Reject sandbox-influenced paths. Checklist: `references/command-surface.md`. +- `--no-verify` skips only the initial check, not the trust requirement; `--show-error` can print secrets. Offer neither as a blanket fix. +- **`--refresh` is cache policy, not revocation.** Service default `55m`, custom `on-demand`. A rotated value can be served from cache until the window ends; removing the source does not revoke the upstream credential. + +### Literal values and custom secrets + +- **Never pass a secret as a plain `--env` value or as a `--kit-arg` / `--env-arg` value.** Both land as literal, unmasked text — in the sandbox's environment, in `sbx env plan`'s state file, and potentially in shell history. Use `sbx secret set` (or `sbxenv.yaml`'s `secrets:`/`registries:` blocks, which route through the same store). +- `secret set --token/-t` and `set-custom --value/--token` put the literal in shell history and process listings: prefer the prompt, stdin (`printf '%s' ...`) or `--ref`. Never write a credential into `--command`, `--ref` or `--token` text: command text is stored and replayed by the daemon, and a dynamic custom record's source text is shown by `secret ls`. +- `sbx secret set-custom` (experimental) covers a service sbx has no built-in support for: the sandbox sees a placeholder in the env var you name (`--env`), and the proxy swaps in the real secret only on requests to the quoted `--host` pattern(s). Global by default; `--sandbox NAME` scopes one. + +### Listing, importing and OAuth shadowing + +- `sbx secret ls [--global|--sandbox NAME] [--service NAME] [--json]` never prints a full literal but is **not metadata-only**, and the mode matters. Default listing (no `--service`) shows service rows as `(stored)` or an OAuth label, registry and custom literals as masked previews, and dynamic **custom** records with their source text. `--service NAME` shows a masked preview of a literal service secret: first six characters, plus last four at 20+ characters (`throwaway-test-value`, 20 characters, renders as `throwa**********alue`). There is no `-v`. Use synthetic fixtures, never paste real listing output into logs, and never infer injection from a listing. +- `sbx secret import [SERVICE] [--all] [--dry-run] [--force]` reads supported host variables and **always writes to the global scope**; use `secret set --sandbox NAME` for one sandbox. `--all` skips a differing stored value, `--force` overwrites, neither bypasses the OAuth-shadow skip (a service with an OAuth token is skipped). Switching to an API key needs `sbx secret rm SERVICE` first, which also removes the OAuth token: confirm with the user. Start with `--dry-run`. + +### Removing secrets: confirmation, missing targets, scoped inverse + +- `sbx secret rm SERVICE` targets the global scope; `--sandbox NAME` a sandbox-scoped secret (for example `sbx secret rm openai --sandbox my-sandbox`; global removal leaves scoped ones); `rm` alone opens a picker. +- `sbx secret rm --all` removes every stored secret of every kind and scope and takes no `SERVICE`, `--sandbox` or `--registry`. Get explicit confirmation naming that blast radius. `--force` skips only the CLI prompt: use it for disposable, user-approved cleanup, not as a shortcut. +- A missing target is an **error** unless `--force` is given; with `--force` it re-runs revocation reconciliation and can succeed, so success does not prove a secret existed. +- Removal is reconciliation, not guaranteed instant revocation. Existing local sandboxes update without a restart, but live revocation can fail after the stored value is deleted: retry with `sbx secret rm --force -- SERVICE`, or for a scoped secret `sbx secret rm --sandbox NAME --force -- SERVICE` (options go before `--`). An HTTP failure or timeout can leave cached credentials usable, and another applicable source may stay effective. Do not say a restart is always required or that deletion proves every sandbox lost access; it never revokes the upstream token. +- Custom-secret removal has no exported public flag at v0.46.0. The implementation has **hidden** `--host`, `--env`, `--placeholder` on `secret rm`. Treat them as internal and version-pinned, not a stable recipe; do not propose them by default. Identify the record with `sbx secret ls --json`, prefer the interactive picker (whether it lists custom records: verify locally), and confirm afterwards that only that record is gone. ### Registry credentials: host-pulls-only by default, two distinct injection scopes -- `sbx secret set --registry HOST --password-stdin` (optionally - `--username`) stores **pull** credentials for a container registry, used - to pull private template images and kit artifacts. **Unlike service - secrets, registry credentials are host-only by default: they authenticate - pulls on the host and are never injected into any sandbox.** +- `sbx secret set --registry HOST --password-stdin` (optionally `--username`) stores **pull** credentials for private template images and kit artifacts. **Unlike service secrets, registry credentials are host-only by default: they authenticate pulls on the host and are never injected into any sandbox.** Docker Hub uses the `sbx login` session. ```bash gh auth token | sbx secret set --registry ghcr.io --password-stdin ``` -- **`--all-sandboxes` and `--sandbox` widen this differently — do not - confuse them:** - - `--all-sandboxes`: credentials are used for host pulls **and** injected - by the proxy into **every new sandbox's** registry login (the - credential itself never enters the sandbox filesystem). - - `--sandbox NAME`: credentials are injected into **that one sandbox - only**. +- **`--all-sandboxes` and `--sandbox` widen this differently — do not confuse them:** + - `--all-sandboxes`: host pulls **and** proxy injection into **every new sandbox's** registry login (the credential never enters the sandbox filesystem).

Prefer `--sandbox`. +- For a Bearer auth endpoint on another host, pass `--registry-auth-endpoint` with the exact trusted HTTPS URL; the registry's own host and built-in relationships (for example Docker Hub) need no flag, other realms are rejected. +- `sbx secret rm --registry HOST --sandbox NAME` removes only that sandbox's registry credential; host-only and global entries are untouched. This does not revoke the upstream token or prevent use of another applicable credential. Without `--sandbox`, `sbx secret rm --registry HOST` removes both the host-only and global entries; add `--all-sandboxes` to remove only the global entry (it requires `--registry`).
