Review instructions, permissions, and files before installation.
Claude skill security
Claude skill security means reviewing the SKILL.md, permissions, and supporting files before you install anything. A quick check prevents surprises from unfamiliar instructions.
Security is especially important before you install skills from sources you do not control.
The security checklist
Check for external calls, file access, and unclear instructions. Confirm the skill only does what its description claims.
