runspec-linux
Linux system-administration runnables (plus Python-venv management, crontab,
filesystem, and the cross-platform web/TLS/API probes) for
runspec. pip install it into a venv and
the runnables are discoverable by runspec local, runspec serve (MCP), and
runspec-console.
All runnables emit JSON on stdout. Read-only runnables are autonomy = "autonomous"; state-changing ones are autonomy = "confirm". The privileged
runnables declare run_as = "root", so runspec-console escalates them via
sudo — run enable-passwordless-sudo once to install a visudo-validated
/etc/sudoers.d drop-in so they run without a password prompt.
Install
pip install runspec-linux

| Sudo bootstrap | enable-passwordless-sudo |
| Python venvs | create-venv, install-into-venv, configure-pip |
| TCP | nc-command |
| Commands | which |
| Cron | cron (multi-verb: list/add/remove/clear) |
| Filesystem | filesystem (multi-verb, backed by runspec-fs-core) |
| Web / TLS / API | cert-check, cert-chain, tls-info, http-check, http-headers, redirect-trace, dns-lookup, api-spec |
The package-management runnables auto-detect apt / dnf / yum / zypper / pacman.
The web/TLS/API probes are pure HTTP (shared with runspec-windows via
runspec-webops-core) and run anywhere.

Python venvs
create-venv, install-into-venv and configure-pip take a per-invocation
--run-as <user> (+ --become-method sudo|su) rather than a declarative
run_as, so the service account that owns a shared venv is chosen per call:
create-venv --python /usr/bin/python3.12 --dest /opt/venvs/ops --run-as svc-ops --group ops
install-into-venv --venv /opt/venvs/ops --package "runspec-linux==0.13.2" --run-as svc-ops
Public Python API
The pure logic lives in runspec-linux-core — no
runspec dependency, no runspec.toml, no entry points (so it surfaces no
runnables). A corporate wrapper package that only wants a helper should depend
on the core alone:
from runspec_linux_core import nc_send, system_info, install_into_venv
The helpers are also re-exported from runspec_linux for back-compat. Core
helpers return plain data and raise (ToolNotFoundError / CommandError) on
failure; the runnable wrappers catch these to render the CLI/agent behaviour.
