git-guardrails-claude-code 安全評估 v1

This is a defensive security skill that sets up Claude Code hooks to block dangerous git commands. The static analyzer flagged several patterns that are false positives: 'Ruby/shell backtick execution' findings are misidentified JSON template syntax in markdown documentation; 'Hidden file in home directory' findings reference the legitimate Claude Code config path ~/.claude/settings.json; and 'Weak cryptographic algorithm' was triggered by the word 'hard' in git reset --hard patterns. The shell script is a straightforward pattern-matching guardrail with no malicious intent. It only blocks commands and never executes any untrusted input.
