Add Kiro Powers support alongside Claude Code Skills

[raifdmueller]

Context

Amazon Kiro IDE has a "Powers" system that is conceptually very similar to Claude Code Skills. Both use a Markdown file with YAML frontmatter as the definition format. Since our Risk Radar skills (/risk-assess, /risk-mitigate) are already structured as SKILL.md files, adding Kiro Power equivalents would be straightforward.

Kiro Powers Format

power-name/
├── POWER.md           # Metadata + instructions (like SKILL.md)
├── mcp.json           # Optional MCP server config
└── steering/          # Optional workflow-specific files

POWER.md frontmatter:

---
name: "risk-assess"
displayName: "Vibe-Coding Risk Assessment"
description: "Analyze repository to assess vibe-coding risk per module"
keywords: ["risk", "security", "vibe-coding", "assessment", "tier"]
---

Key difference: Kiro Powers activate automatically via keywords (e.g. mentioning "risk assessment" loads the power), while Claude Code Skills are invoked explicitly.

Tasks

• Create POWER.md for risk-assess (adapt from existing SKILL.md)
• Create POWER.md for risk-mitigate (adapt from existing SKILL.md)
• Add keywords field for automatic activation
• Consider steering/ files for the multi-step workflows
• Update DocSidebar documentation (both DE/EN) to mention Kiro Powers installation
• Update install-skills.sh or create separate install-powers.sh
