Check external services, hosts, browser sessions, model endpoints, and agents before an end-to-end run. MANUAL-ONLY: load when a caller names it. NEVER auto-load from context for ordinary testing or debugging.
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
# e2e-environment-preflight — the gate that runs before the first row **Never auto-triggered.** Named callers only: | Caller | Moment | |---|---| | A requirements document or test plan | once end-to-end proof is required and the document names an external system | | A task brief | before staffing any end-to-end journey | | `e2e-red-triage` | when a red turns out to be environmental and owes a new check | This skill is self-contained: the trigger and the three artifacts. Terms: the **owner** is whoever owns the work, usually the user; a **row** is one acceptance check in the test plan; a **journey** is one end-to-end scenario made of rows; a **red** is a row that failed or gave no answer; the **suite** is all the rows of a journey. **Each repository binds this locally.** A repo-level `e2e-environment-preflight` names its own systems, its own primer directory, its own evidence paths, and its own configuration decisions. This file is the contract; the local one is the address book. If the repository has no local binding, the first journey that needs one writes it. ## The trigger, as an operational test …

How to install
mdr add sno-ai/sno-station-skills/e2e-environment-preflight@sha256:9fa4510bb0480be0The line at the top of this page pins the label git:20261001.8e39faf, 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.
