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 signature…

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'verify-sign' ] || [ -L ~/.agents/skills/'verify-sign' ]; then echo 'A skill folder named verify-sign already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/harness/harness-skills' "$d" && git -C "$d" checkout --quiet '9c274a3c1cebc5cf26e5501c118e1ff03b63502f' -- 'skills/security/verify-sign' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/security/verify-sign' ~/.agents/skills/'verify-sign' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'verify-sign' ~/.claude/skills/'verify-sign' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
