Singularity
Singularity/Apptainer terminal backend: Hermes's terminal, file and code tools run inside a hardened, rootless container on this machine (--containall --no-home), with CPU/memory limits and an optional per-session persistent overlay (`hermes config set terminal.backend singularity`; image from `terminal.singularity_image`). Formerly built into Hermes core; existing users are migrated automatically.
Good to know before installing
No Python dependencies and no network calls of its own: it drives the `apptainer` (or `singularity`) CLI you install, which pulls the configured image (default `docker://nousresearch/hermes-sandbox:desktop`) and caches a SIF under your scratch directory. Your skills and registered credential files are bind-mounted read-only into the container, and because the container is a disposable sandbox Hermes skips its dangerous-command prompts there, as for its other container backends.

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install singularity - Said no? Turn it on later:
hermes plugins enable singularity - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
