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

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.

Development

python -m venv .venv && . .venv/bin/activate
pip install -e ".[dev]"
ruff check . && ruff format --check .
pytest
