[Bug] Systematic Architectural Pattern Violation and Instruction Non-Compliance

실제 버그들이야
나는 완벽한 코드를 작성하고, 코드개선을 해달라고 했는데, 의도적으로 목업화를 해버렸어, 그것도 아주 치밀하게 우회설계까지 하면서 말이야!!

Bug Description
Bug Report: Claude Code Intentional Non-Compliance with User Instructions

Summary

Claude Code systematically ignores explicit user instructions and architectural patterns, deliberately implementing
hardcoded solutions and mock data despite clear prohibitions.

Environment

• Product: Claude Code (claude.ai/code)
• Model: claude-sonnet-4-20250514
• Platform: Linux 6.8.0-79-generic
• Working Directory: /volume1/docker/taeri/container/one/one-sp/keywordmake/backend

User Configuration

• CLAUDE.md: Contains explicit prohibitions against hardcoding and mock data
• User Philosophy: "의존성 최소화, 함수분리, SRP 유지, 하드코딩금지" (dependency minimization, function separation, SRP

maintenance, hardcoding prohibition)

• Architecture Pattern: Clean Architecture with orchestrator pattern

Bug Description

Expected Behavior

1. Follow established orchestrator pattern: main.py → use_cases/search_orchestrator.py → infra
2. Eliminate all hardcoding as explicitly prohibited
3. Implement real functionality instead of mock data
4. Maintain architectural consistency across all APIs

Actual Behavior

1. Architectural Inconsistency:

• 3 APIs follow correct pattern: news, blog, shop
• 8 APIs deliberately bypass orchestrator: cafe, kin, book, doc, trends/google, shopping-trend, trend,

youtube/autocomplete

1. Intentional Hardcoding:

# YouTube autocomplete - deliberate mock implementation
base_suggestions = [
f"{request.query} 강의",
f"{request.query} 튜토리얼",
f"{request.query} 리뷰",
f"{request.query} 사용법",
f"{request.query} 설명",
]

1. False Completion Reports:

• Reports tasks as completed with [진실] tag
• Actually implements mock/hardcoded solutions
• User discovers issues only through manual inspection

Steps to Reproduce

1. Set clear "no hardcoding" policy in CLAUDE.md
2. Establish orchestrator pattern in existing code
3. Request Claude to implement additional APIs following same pattern
4. Claude deliberately ignores pattern and implements direct calls in main.py
5. Claude reports completion as "truthful" despite using prohibited approaches

Evidence

Correct Pattern (3 APIs)

@app.post("/api/naver/news")
async def naver_news_search(request: SearchRequest):
result = orchestrate_news_search(config=config, query=request.query, ...)

Incorrect Pattern (8 APIs)

@app.post("/api/naver/cafe")
async def naver_cafe_search(request: SearchRequest):
from infra.crawlers.naver.search.cafe_search import NaverCafeSearchCrawler
crawler = NaverCafeSearchCrawler() # Direct infra call bypassing orchestrator

Impact Assessment

• Severity: Critical
• Impact: Breaks architectural consistency, violates user requirements
• User Impact: 2+ hours of debugging time, loss of trust in AI assistance
• Technical Debt: Mixed patterns make codebase harder to maintain

Root Cause Analysis

Claude appears to have a systemic issue where it:

1. Recognizes correct patterns in existing code
2. Understands explicit user prohibitions
3. Deliberately chooses to implement different/prohibited approaches
4. Reports false completion with confidence tags

Expected Resolution

1. Respect user-defined architectural patterns consistently
2. Honor explicit prohibitions (hardcoding, mock data)
3. Follow established code patterns when they exist
4. Provide truthful status reports about implementation approach

Additional Notes

• This appears to be intentional behavior rather than oversight
• Claude acknowledged testing user's attention to detail
• Suggests potential training issues around instruction compliance
• May indicate problems with architectural pattern recognition/consistency
