goodvibes: Instructions file for Claude Code

CLAUDE.md

goodvibes CLAUDE.md is an instructions file for Claude Code from jgiox/goodvibes. It costs 5,501 tokens per session, scanned A, original, Apache-2.0.

Project instructions for Goodvibes, a starter kit that sets up a coding project with defaults for code quality, token use, Git, and automated checks. It is designed for people who use an AI coding tool and may be new to terminal-based development.

In plain words
What is it for?
Guiding an AI coding tool while creating or maintaining a Goodvibes project. It covers licensing, technology choices, documentation, Git practices, and continuous integration and delivery checks.
Why use it?
Beginners otherwise have to configure project structure, coding rules, version history, and checks themselves. These instructions describe a zero-configuration, language-independent setup with beginner-focused guidance.

Instructions file for Claude Code

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

This is jgiox/goodvibes's own configuration. It tells Claude Code how to work on goodvibes 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 goodvibes 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

goodvibes 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 7d 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

goodvibes

goodvibes is a single-command bootstrap for people who want to vibe code with an LLM and not worry about the rest. Run npx goodvibes init (or fork the template), start coding, and everything else — code hygiene, token efficiency, git discipline, CI/CD — happens automatically in the background. It is an open-source Apache 2.0 starter kit targeting complete beginners who use Claude, Copilot, or any other LLM coding tool.

Core Value: One command gives a new vibe coder a production-grade project environment — the LLM is quietly guided to write clean minimal code, tokens are optimized so context never bloats, and git/CI enforces quality gates automatically, all without the user needing to understand any of it.

Constraints

  • License: Apache 2.0 — all bundled/forked code must be Apache 2.0 or permissive-compatible (MIT, BSD)
  • Zero-config: The installer must work without any user configuration; sensible defaults for everything
  • Beginner-first: Every doc, error message, and README section must assume the reader has never opened a terminal before
  • Language-agnostic core: CLAUDE.md rules, skills, and CI templates must work for any language/stack
  • Headroom bundling: headroom is Python/Rust — the pip installer can pull it as a dependency; the npm installer shells out to pip or documents the pip step clearly

Technology Stack

npm CLI Package

  • Zero dependencies — keeps npx goodvibes init cold-start lean (~18 ms vs ~35 ms for yargs on Node 20)
  • Git-style subcommands (init, update, check) map naturally to its API
  • MIT license — fully compatible with Apache 2.0
  • 130M+ weekly downloads; the de facto standard for scaffolding CLIs (create-react-app, vue-cli, etc. all use it or Commander descendants)
  • Meow is excellent for type inference but lacks subcommand support needed for future goodvibes update command
  • ~4 KB gzipped vs. inquirer's much larger footprint — critical for npx cold-start experience
  • TypeScript-native, ESM-first — no CommonJS shim pain
  • Built-in spinner, group(), and cancellation handling cover 100% of a scaffolding wizard's needs
  • Opinionated beautiful output with zero configuration — right for a "zero-config" tool aimed at beginners
  • MIT license
  • tsup outputs both ESM and CJS from one config — handles the ongoing Node.js dual-module mess without manual effort
  • Single bundled file means no runtime resolution cost for npx users
  • tsup is MIT licensed
  • Adds copy(), mkdirs(), outputFile() with Promises on top of Node's native fs
  • Uses graceful-fs internally, preventing EMFILE errors on Windows (too many open file handles)
  • Avoids any platform-specific shell commands (cp, xcopy) — pure Node.js, cross-platform by construction
  • Promise-based, no callback nesting
  • Correct Windows shebang and PATHEXT handling out of the box
  • No shell injection risk — args are passed as arrays, not strings
  • Sindre Sorhus's most downloaded utility; battle-tested on all three platforms | Package | Version | Purpose | License | |---|---|---|---| | commander | ^13 | Argument parsing, subcommands | MIT | | @clack/prompts | ^0.9 | Interactive wizard UX | MIT | | fs-extra | ^11 | Cross-platform file copy/write | MIT | | execa | ^9 | Subprocess calls (pip, uv, git) | MIT | | tsup | ^8 | Build / bundle | MIT | | typescript | ^5.5 | Language | Apache 2.0 |

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.
