vibe-project: Instructions file for Claude Code

CLAUDE.md

vibe-project CLAUDE.md is an instructions file for Claude Code from jhl-labs/vibe-project. It costs 761 tokens per session, scanned A, original, MIT.

A Korean-language project instruction file for Claude Code that documents a project’s structure, commands, technology choices, coding rules, architecture, and security requirements.

In plain words
What is it for?
It helps maintain projects by documenting development commands, naming and formatting rules, layered architecture, commit conventions, and restrictions such as not hard-coding secrets.
Why use it?
It gives the coding agent project-specific guidance so it knows how to install dependencies, run checks, organize code, and avoid prohibited practices.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is jhl-labs/vibe-project's own configuration. It tells Claude Code how to work on vibe-project itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vibe-project configures →

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

vibe-project CLAUDE.md 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 8d ago.

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.

  3. 에러 처리 포함
  4. 새 의존성 추가 전 기존 라이브러리 확인

리뷰 시

  1. 보안 취약점 우선 확인
  2. 에러 처리 검증
  3. 성능 이슈 체크
  4. 컨벤션 준수 여부

Changes

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.
