CLAUDE.md

project-init CLAUDE.md is an instructions file for Claude Code from whchoi98/project-init. It costs 1,431 tokens per session, scanned A, original, MIT.

Project instructions for Claude Code that document a codebase’s purpose, technology, folder layout, conventions, and common commands. They also describe tools for creating and keeping project documentation up to date.

In plain words
What is it for?
Use them to initialize project documentation, generate a README, check documentation quality, synchronize docs, and follow project-specific commands and conventions.
Why use it?
They give the coding agent the context it needs to work consistently in an unfamiliar project. They also reduce missing or outdated setup and documentation details.

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

project-init 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 1mo 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.

Project Context

Overview

project-init is a Claude Code plugin marketplace that provides project structure initialization, documentation quality scoring, and auto-sync workflows. The main plugin lives in plugins/project-init/.

Tech Stack

  • Claude Code Plugin System (commands, skills, agents as Markdown/YAML)
  • Bash (hook scripts, setup scripts)
  • Git (version control, commit-msg hooks)
  • Markdown (all plugin definitions, documentation, templates)

Conventions

  • Language: Bilingual (Korean/English) for all user-facing docs (README, CHANGELOG, architecture, ADR, runbook); see writing-style-guide.md
  • Plugin structure: Commands and agents are .md files with YAML frontmatter (Claude Code does not load .yml agents)
  • Reference templates: Stored in skills/project-scaffolder/references/ as Markdown with embedded code blocks
  • Versioning: Semantic versioning; version tracked in marketplace.json and plugin.json
  • Commit messages: Co-Authored-By lines auto-removed by commit-msg hook
  • Hooks: read event JSON from stdin, block with exit 2; no hardcoded counts (tests, files) in docs (ADR-008)
  • Indentation: 2 spaces (see .editorconfig)
  • Line endings: LF

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.
