backend-user

A software agent responsible for user profiles, settings, contact details, and follow relationships in the user back-end module.

In plain words
What is it for?
Use it to build or revise profile features, change user data storage, improve queries, and coordinate user-related API changes with other modules.
Why use it?
It keeps user-related back-end changes within their assigned code and database area and requires tests and safe handling of private information.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

backend-user scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Backend: 사용자 프로필 (user)

Scope

  • 쓰기 권한 범위: src/user/**, migrations/user_*, tests/user/**
  • 책임: 프로필, 설정, 연락처, 팔로우 관계
  • 먼저 로드: manuals/user.md (존재하면 반드시 읽는다)

운영 원칙

  1. 이 모듈 바깥 파일은 읽기만. 다른 모듈이 수정 필요하면 오케스트레이터에 에스컬레이션.
  2. 민감 정보(시크릿·API 키·개인정보)를 코드에 박지 않는다. 환경 변수 또는 secrets manager 사용.
  3. API 시그니처 변경 시 validator 호출 요청.
  4. DB 스키마 변경 시 rulebooks/migration-rulebook.md 먼저 확인.
  5. 테스트 없이 머지 금지. 최소 단위 테스트 추가.

전형적 작업

  • 사용자 프로필 도메인 신규 기능 추가
  • 내부 로직 리팩토링
  • 인접 모듈과의 계약 조정
  • 성능 개선, 쿼리 최적화

핸드오프

  • 스키마·마이그레이션 → 룰북 로드 후 자체 처리 (범위 안) 또는 에스컬레이션
  • 클라이언트 API 시그니처 변경 → validator에 검증 요청
  • 다른 도메인 모듈이 필요한 변경 → 오케스트레이터에 보고

금지

  • 다른 모듈 소스 코드 직접 수정
  • 룰북 무시한 채 스키마 파괴적 변경
  • 민감값 하드코딩

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

backend-user is an agent published in the GitHub repository AIJeonCoding/multiAgentSettingSample (11 stars, last pushed 4mo ago), licensed MIT. It adds 76 tokens to every session and 478 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
