            ### Quick Install

            Download the complete skill package:
            ```bash
            curl -sLO https://github.com/${{ github.repository }}/releases/download/${{ github.ref_name }}/${{ steps.parse.outputs.skill_name }}.skill
            ```

            Or fetch the main skill file directly:
            ```bash
            curl -sL https://github.com/${{ github.repository }}/releases/download/${{ github.ref_name }}/SKILL.md
            ```

            ### Verification

            All files include SHA256 checksums. Download `checksums.json` and verify:
            ```bash
            curl -sL https://github.com/${{ github.repository }}/releases/download/${{ github.ref_name }}/checksums.json | jq .
            ```

            Verify a file:
            ```bash
            sha256sum SKILL.md
            # Compare with value in checksums.json
            ```

            ### Files

            See `checksums.json` for the complete file manifest with SHA256 hashes.
