Run a third-party CLI as a subprocess without leaking into it or leaving state on the host, and prove both. Use when a script or skill shells out to an external tool, when a run must leave no trace outside the repository, when private input (a diff, a prompt, a credential) must not reach the tool's session log, when a policy or deny-list handed to the tool must actually be in force, when a claim about the tool's own behaviour (which paths it searches, which config file wins) must be settled…
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
# Confine an External CLI A CLI invoked as a subprocess is not a function call. It reads the operator's global configuration, writes per-run state under the home directory keyed to the directory it ran in, and treats a config file it cannot compile as advice rather than as an instruction. None of those three shows up in an exit code: the private content piped in lands in a plaintext log outside the repository, the host accumulates state nobody audits, and the confinement believed to be in force is absent. This skill is the mechanics of running such a tool and being able to say afterwards what it read, what it wrote, and what it left behind. Whether the run's *result* is evidence is a separate question and belongs to `prove-checks`. ## Trigger - A script or skill invokes a third-party CLI as a subprocess: an agent CLI, a linter with a cache, a package manager, a formatter, anything with a state store outside the working directory. - A second tool or provider branch is added to a script that already does this. - The tool is handed a policy, deny-list, allow-list or sandbox configuration. - The content piped in is private: an unmerged diff, a prompt, a credential, customer data. …

How to install
mdr add sergeyklay/.agents/isolate-cli@sha256:d8cea9128c910c32The line at the top of this page pins the label v1.1, 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.
