  Both skills are PROVIDER-PUBLISHED and saved verbatim (SKILL.md frontmatter + body unchanged) from the public
  horizon-shield repository on 2026-09-19. horizon-shield ships inside the provider's Claude Code plugin
  (plugin/skills/horizon-shield/SKILL.md) next to three slash commands; conduct-witness is a repo-level skill
  (skills/conduct-witness/SKILL.md). Every tool name they reference was checked against the live tools/list saved in
  mcp/horizonshield-dev-mcp-tools.json — the plugin skill names 14 tools (the server now lists 15; get_agent_card is
  named, verify_integrity_claim is named; the count in the plugin README predates the current list). Nothing was
  generated: with no OpenAPI for the KIRA server, MCP tool names are the operations these skills ground in.
