What this skill does

Attestation is a community-contributed Claude Code skill in the crypto-keymgmt sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/attestation/ and loads when your prompt matches the skill's trigger.

It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 153,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
