Add an SLSA Verification (SlsaVerification) step to an existing Harness pipeline to verify SLSA provenance attestations and optionally enforce OPA policy sets on provenance data. Supports CI and CD (Deployment) including CI-only pipelines — append a Deploy stage via Phase 3b when verifying before deploy. Supports Docker, ECR, GCR, GAR, ACR, HAR, and Local artifacts. Only works with existing pipelines. Use when asked to verify SLSA, enforce SLSA policies, add SLSA verification step, validate…
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
# Enforce SLSA Add an **SLSA Verification** (`SlsaVerification`) step to an existing Harness pipeline. The step verifies SLSA provenance attestations (when enabled) and optionally evaluates OPA policy sets against provenance data. This skill only works with **existing pipelines** — do not create standalone verification-only pipelines. **Prerequisites:** SLSA provenance must already exist for the artifact (typically from a `provenance` step via `/generate-slsa` — UI label SLSA Generation). Optional **policy sets** for provenance enforcement (`/create-policy`, `harness_list` `policy_set`). **Supported stages:** CI, CD (`Deployment`), and Security. CD requires a **containerized step group**. Unlike SBOM enforcement, CI and CD both use **`SlsaVerification`** (no separate CD step type). Guide the user through a **step-by-step interactive wizard** (same UX as `/generate-slsa`): - Wizard: `references/interactive-wizard-flow.md` - UI ↔ YAML: `references/slsa-verification-step.md` - CD containerized step groups: `skills/security/generate-slsa/references/cd-containerized-step-group.md` --- ## Interaction model (mandatory) …

How to install
mdr add harness/harness-skills/enforce-slsa@sha256:b22eb7bc51735d86The line at the top of this page pins the label v1.0.0, 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.
