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.

Coding Style
Immutability (CRITICAL)
ALWAYS create new objects, NEVER mutate existing ones:
// Pseudocode
WRONG: modify(original, field, value) → changes original in-place
CORRECT: update(original, field, value) → returns new copy with change
Rationale: Immutable data prevents hidden side effects, makes debugging easier, and enables safe concurrency.
File Organization
MANY SMALL FILES > FEW LARGE FILES:
- High cohesion, low coupling
- 200-400 lines typical, 800 max
- Extract utilities from large modules
- Organize by feature/domain, not by type
Error Handling
ALWAYS handle errors comprehensively:
- Handle errors explicitly at every level
- Provide user-friendly error messages in UI-facing code
- Log detailed error context on the server side
- Never silently swallow errors
Input Validation
ALWAYS validate at system boundaries:
- Validate all user input before processing
- Use schema-based validation where available
- Fail fast with clear error messages
- Never trust external data (API responses, user input, file content)
Code Quality Checklist
Before marking work complete:
- Code is readable and well-named
- Functions are small (<50 lines)
- Files are focused (<800 lines)
- No deep nesting (>4 levels)
- Proper error handling
- No hardcoded values (use constants or config)
- No mutation (immutable patterns used)
