Use when running a small product on core Google Cloud via the gcloud CLI: a project, Cloud Run deploys, a locked-down Cloud Storage bucket, managed Cloud SQL, and least-privilege IAM wiring them together. NOT AWS (that is `aws-essentials`), NOT the CI pipeline that ships the image (that is `deployment`), NOT Postgres schema/query tuning (that is `postgresdb`).
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
# GCP essentials Get a small product running on the core of Google Cloud — safely and cheaply — with the `gcloud` CLI as the source of truth. The console is fine for reading; the CLI is what you commit, review, and reproduce. Bias toward **secure-by-default and near-zero bill**, not "every GCP service". Four primitives carry most products, plus the project/billing scaffold under them: - **IAM** — who can do what. Get this wrong and nothing else matters. - **Cloud Run** — serverless containers, scale to zero. - **Cloud Storage** — object storage (buckets). - **Cloud SQL** — managed Postgres/MySQL. Out of scope, route elsewhere: AWS -> [`../aws-essentials/SKILL.md`](../aws-essentials/SKILL.md). Building/shipping the image itself -> [`../docker/SKILL.md`](../docker/SKILL.md) / [`../github-actions/SKILL.md`](../github-actions/SKILL.md) / [`../deployment/SKILL.md`](../deployment/SKILL.md). Postgres schema/index/query tuning -> [`../postgresdb/SKILL.md`](../postgresdb/SKILL.md). App-level injection/secret-handling review -> [`../secure-coding/SKILL.md`](../secure-coding/SKILL.md). Logging/alerting/SLOs as a practice -> [`../monitoring/SKILL.md`](../monitoring/SKILL.md). …

How to install
mdr add ericrisco/rsc-harness/gcp-essentials@sha256:9ebf32e3706a5cf8The line at the top of this page pins the label git:20260729.ad893da, 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.
