Shared rules for test runs that drive the running app or run a test target: isolation from concurrent runs, stubs for infrastructure that cannot be stood up, provisioning privileged state, approval before writes to shared external systems, and cleanup of only what the run created. Not typically invoked directly.
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
# Test Run Rules Apply these rules for the rest of the test run, whether it drives the running app or runs a test target. A scenario they leave **blocked** could not be set up or run; one they leave **inconclusive** ran, but its result cannot be read. ## Isolation - Isolate shared process state so concurrent or sub-agent runs don't collide: bind dev servers and services to unique ports, scope tmux sessions (`tmux -L <name>`), give each browser session a unique name so cleanup can target only its own, and write screenshots and other scratch state to absolute paths under a uniquely named subdirectory of `$TMPDIR`. Derive each such identifier once and reuse that exact value in every later command, writing it as a literal or reading it back from a note in that subdirectory. A value recomputed per shell, such as `$$`, differs between the command that creates a resource and the command that releases it, so cleanup releases something it never created and reports success while the real resource leaks. A port picked as unique may already be held by a concurrent agent, so check it before binding and move to another when it is taken, leaving the incumbent running. When a unique port moves …

How to install
mdr add tobihagemann/turbo/test-run-rules@sha256:3cb567c8a5399385The line at the top of this page pins the label git:20261021.bd9c95d, 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.
