claude-init: Instructions file for Claude Code

CLAUDE.md

claude-init CLAUDE.md is an instructions file for Claude Code from yash-gadodia/claude-init. It costs 561 tokens per session, scanned C, original, MIT.

A setup process that makes an existing software repository easier for AI assistants to understand and work on. It examines the codebase and creates project-specific guidance, documentation, skills, agents, rules, and hooks.

In plain words
What is it for?
It helps prepare a repository for AI-assisted development by documenting its language, framework, tests, architecture, CI setup, and working conventions.
Why use it?
It removes the need to configure AI assistance by hand for every repository. It also creates an architecture document and can bootstrap tests when none exist.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is yash-gadodia/claude-init's own configuration. It tells Claude Code how to work on claude-init 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 claude-init 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 C, and why

claude-init CLAUDE.md scanned grade C with 2 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

claude-init

Makes any repo AI-native by generating a complete .claude/ configuration tailored to the codebase.

What This Does

Point this at any existing (or new) repo and run /claude-init to:

  1. Analyze the codebase (language, framework, tests, CI, architecture, patterns)
  2. Bootstrap a test suite if none exists
  3. Generate ARCHITECTURE.md for deep project context
  4. Generate tailored CLAUDE.md, agents, rules, skills, and hooks
  5. Skills include: clarify (with spec persistence), plan, TDD, review, verify, subagent-dev, finish
  6. Every skill has rationalization prevention ("Red Flags — STOP" tables)
  7. Auto-triggered workflow rule — Claude follows the full pipeline without slash commands

Usage

# Install globally (skills → ~/.claude/skills/, templates → ~/.claude/claude-init-templates/)
curl -fsSL https://raw.githubusercontent.com/yash-gadodia/claude-init/main/scripts/install.sh | bash

# Or load the repo as a plugin
git clone [email protected]:yash-gadodia/claude-init.git ~/claude-init
claude --plugin-dir ~/claude-init

# Then, in the TARGET repo:
cd /path/to/your-existing-repo && claude
# Type: /claude-init

Architecture

See ARCHITECTURE.md for the full system map. Quick tour:

  • templates/ — Template files that get customized per-repo during setup
  • .claude/skills/claude-init/ — The main generator skill (analyzes repo, writes config)
  • .claude/skills/onboard/ — Quick onboarding skill for new devs joining a repo
  • .claude/skills/update/ — Refresh config when the repo evolves
  • .claude/skills/doctor/ — Validate generated config
  • scripts/ — Install script and helpers
  • tests/run.sh — zero-dependency self-test suite; run before committing template changes

Design Principles

  • Progressive disclosure: Frontmatter stays tiny (~100 tokens), full content loads on demand
  • Stack-aware: Detects framework, language, test runner, CI, and tailors everything
  • Opinionated defaults, easy overrides: Generates best-practice config you can customize
  • Security-first: Hooks block destructive ops by default
  • Agent personas: Each role (architect, dev, QA) gets model-appropriate config (Opus for critical thinking, Sonnet for implementation, Haiku for fast ops)

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.
