iac-security-scanner: Add README.md to skill directory #3
Description
Summary
The skills/iac-security-scanner/ directory has a SKILL.md (the Agent Skills spec file) but no README.md. When browsing the directory on GitHub, there's no rendered overview.
Proposed Change
Add a lightweight README.md to skills/iac-security-scanner/ that:
- Provides a quick overview of the skill's capabilities
- Links to
SKILL.mdfor the full specification - Shows the directory structure (references, scripts)
- Lists supported providers with policy counts
- Notes that this skill has no npm dependencies (unlike mesh-security)
This is a documentation convenience — SKILL.md already serves as the primary specification for agent platforms.
Impact
- Improves GitHub browsing experience
- No functional changes
- Low effort
