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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.05501 | $0.05501 |
| Opus 5 | $0.02750 | $0.02750 |
| Sonnet 5 | $0.01100 | $0.01100 |
| Haiku 4.5 | $0.00550 | $0.00550 |
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
Recommended Stack
npm CLI Package
- Zero dependencies — keeps
npx goodvibes initcold-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 updatecommand - ~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 nativefs - Uses
graceful-fsinternally, preventingEMFILEerrors 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

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.

goodvibes CLAUDE.md is an instructions file published in the GitHub repository jgiox/goodvibes (4 stars, last pushed 2d ago), licensed Apache-2.0. It adds 5,501 tokens to every session, about $0.0275 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 2026-08-31.
