park-kyungchan 1bd68ff534 feat(ecc): prune plugin 43→12 items, promote 7 rules to .claude/rules/ (#245)
ECC community plugin pruning: removed 530+ non-essential files
(.cursor/, .opencode/, docs/ja-JP, docs/zh-CN, docs/zh-TW,
language-specific skills/agents/rules). Retained 4 agents,
3 commands, 5 skills. Promoted 13 rule files (8 common + 5
typescript) to .claude/rules/ for CC native loading. Extracted
reusable patterns to EXTRACTED-PATTERNS.md.

Security Guidelines

Mandatory Security Checks

Before ANY commit:

  • No hardcoded secrets (API keys, passwords, tokens)
  • All user inputs validated
  • SQL injection prevention (parameterized queries)
  • XSS prevention (sanitized HTML)
  • CSRF protection enabled
  • Authentication/authorization verified
  • Rate limiting on all endpoints
  • Error messages don't leak sensitive data

Secret Management

  • NEVER hardcode secrets in source code
  • ALWAYS use environment variables or a secret manager
  • Validate that required secrets are present at startup
  • Rotate any secrets that may have been exposed

Security Response Protocol

If security issue found:

  1. STOP immediately
  2. Use security-reviewer agent
  3. Fix CRITICAL issues before continuing
  4. Rotate any exposed secrets
  5. Review entire codebase for similar issues
