Governed runtime for agent skills: discover and install portable skills, run bounded skill graphs with explicit authority, and inspect signed receipts for what happened.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# runx References: [spec](https://runx.ai/spec), [catalog](https://runx.ai/x), [doctrine](https://runx.ai/doctrine), [overview](https://runx.ai/what), [source](https://github.com/runxhq/runx). runx is the governed runtime for agent skills. Use it when an agent needs to do real work through a portable skill while preserving four properties: 1. the skill being run is explicit; 2. the authority granted to it is bounded; 3. consequential actions pass through a gate; 4. the run leaves a signed receipt that can be inspected later. A runx skill is not just a prompt. It is a small, portable package with a `SKILL.md` contract, optional graph/config files, and enough procedural context for an agent to execute deliberately instead of improvising hidden side effects. ## When to use runx Use runx when the task involves one or more of these: - running a third-party or project-owned skill from a catalog, repo, or local path - chaining multiple skill steps into a bounded workflow - touching money, credentials, deployments, public messages, production systems, customer data, or other consequential surfaces - proving what happened after an agent acted …

How to install
mdr add runxhq/runx/runx@sha256:c5bff1eb08b39334The line at the top of this page pins the label git:20261017.16ba3f9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
