Codex System — Deep Reasoning Partner

Codex CLI (gpt-5.2-codex) is your highly capable supporter for deep reasoning tasks.

상세규칙:

.claude/rules/codex-delegation.md

Context Management (CRITICAL)

서브에이전트 경유 권장이다. 메인 오케스트레이터의 컨텍스트를 절약하기 위해.

상황	방법
자세한 설계 상담	서브 에이전트를 통해 (권장)
디버그 분석	서브 에이전트를 통해 (권장)
짧은 질문 (1-2 문 답변)	직접 호출 확인

When to Consult (MUST)

Situation	Trigger Examples
Design decisions	"어디 디자인?" "아키텍처" / "How to design?"
Debugging	"왜 움직이지 않는가?" "오류" / "Debug" "Error"
Trade-off analysis	"어느 쪽이 좋은가?" "비교해" / "Compare" "Which?"
Complex implementation	"구현 방법" "어떻게 만드는가?" / "How to implement?"
Refactoring	"리팩터" "간단하게" / "Refactor" "Simplify"
Code review	"리뷰하고" "확인하고" / "Review" "Check"

When NOT to Consult

Simple file edits, typo fixes
Following explicit user instructions
git commit, running tests, linting
Tasks with obvious single solutions

How to Consult

Recommended: Subagent Pattern

Use Task tool with

subagent_type='general-purpose'

to preserve main context.

Task tool parameters:
- subagent_type: "general-purpose"
- run_in_background: true (optional, for parallel work)
- prompt: |
    Consult Codex about: {topic}

    codex exec --model gpt-5.2-codex --sandbox read-only --full-auto "
    {question for Codex}
    " 2>/dev/null

    Return CONCISE summary (key recommendation + rationale).

Direct Call (Short Questions Only)

For quick questions expecting 1-2 sentence answers:

codex exec --model gpt-5.2-codex --sandbox read-only --full-auto "Brief question" 2>/dev/null

Workflow (Subagent)

Spawn subagent with Codex consultation prompt
Continue your work → Subagent runs in parallel
Receive summary → Subagent returns concise insights

Sandbox Modes

Mode	Use Case
`read-only`	Analysis, review, debugging advice
`workspace-write`	Implementation, refactoring, fixes

Language Protocol

Ask Codex in English
Receive response in English
Execute based on advice (or let Codex execute)
Report to user in Korean

Task Templates

Design Review

codex exec --model gpt-5.2-codex --sandbox read-only --full-auto "
Review this design approach for: {feature}

Context:
{relevant code or architecture}

Evaluate:
1. Is this approach sound?
2. Alternative approaches?
3. Potential issues?
4. Recommendations?
" 2>/dev/null

Debug Analysis

codex exec --model gpt-5.2-codex --sandbox read-only --full-auto "
Debug this issue:

Error: {error message}
Code: {relevant code}
Context: {what was happening}

Analyze root cause and suggest fixes.
" 2>/dev/null
