verify-sign SKILL.md skillA
verify-sign from harness/harness-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add harness/harness-skills/verify-sign@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Add an Artifact Verification (SscaArtifactVerification) step to an existing Harness pipeline to verify Cosign signatures on container or local-stage artifacts. Supports CI, Security, and CD Deploy (containerized step group). Supports Third-Party registries (Docker, ECR, GCR, GAR, ACR), Harness Artifact Registry (HAR), and Harness Local Stage artifacts. Only works with existing pipelines. Use when asked to verify signed artifacts, verify artifact signature, verify-sign, validate Cosign…
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
# Verify Sign Add an **Artifact Verification** (`SscaArtifactVerification`) step to an existing Harness pipeline. The step verifies Cosign signatures on artifacts — typically immediately after `SscaArtifactSigning`. This skill only works with **existing pipelines** — do not create standalone verification-only pipelines. **Prerequisites:** Artifact must already be signed (typically via `/sign-artifact` / `SscaArtifactSigning`). Key-based verify requires the Cosign **public** key file secret matching the signing private key (`/create-secret`). If signing did not upload `.sig` to the registry, Harness pulls the signature from its database during verification. **Supported stages:** CI, Security, and CD (`Deployment` in containerized step group before deploy). Guide the user through a **step-by-step interactive wizard** (same UX as `/sign-artifact`): - Wizard: `references/interactive-wizard-flow.md` - UI ↔ YAML: `references/artifact-verification-step.md` - CD containerized step groups: `references/cd-containerized-step-group.md` --- ## Interaction model (mandatory) 1. **One question per turn** — use `AskQuestion` when available; otherwise numbered options with `(Recommended)`. …

How to install
mdr add harness/harness-skills/verify-sign@sha256:1fe9bf33f94445f3The 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.
