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 | $0.01037 | $0.01037 |
| Opus 5.5 | $0.00415 | $0.00415 |
| Sonnet 5.5 | $0.00207 | $0.00207 |
| Haiku 4.5 | $0.00104 | $0.00104 |
Grade A, and why
no-vibe 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Repo purpose
This repo is the no-vibe plugin for Claude Code, Codex, opencode, Pi and Antigravity. Developing the plugin is normal editing. The write guard applies only when .no-vibe/active exists at the repo root.
What no-vibe is for
People learn by doing the thinking and by typing code by hand. In an existing project the agent first reads it and saves what it learns to .no-vibe/project.md, so its questions, goal options and syllabus fit the project and nothing it teaches breaks what already works. It finds the user's level with concrete multiple-choice questions, agrees a goal with them, and writes a high-level syllabus they approve. It teaches each section briefly, concept first or code first, chosen per section. Each section gets at least 3 standalone exercises with the full code shown, so the user builds muscle memory by typing it. Later sections reuse earlier material.
Test every teaching change against one question: does the user still think and still type every line?
Sources and generated files
The hand-edited sources are no-vibe.config.json, skills/*/SKILL.md, hooks/*.sh, hooks/run-hook.cmd, bin/, lib/, runtimes/, tests/ and the prose docs. Everything listed in .no-vibe-manifest is generated. Edit the source, run npm run generate, and never hand-edit a generated file. npm run check fails when a generated file is stale.
The version lives only in no-vibe.config.json.
Write guard
hooks/block-writes.sh and hooks/block-bash-writes.sh are the only guard implementation. Claude Code, Codex and Antigravity call them as hooks, and opencode and Pi call them from their generated plugins.
The Write-tool guard allows writes only under .no-vibe/** and $HOME/.no-vibe/**, and refuses a path through a symlink or longer than 4000 bytes. The Bash guard reads each command's text and also allows /tmp/**, /var/tmp/**, /dev/null, /dev/stdout, /dev/stderr, /dev/tty and /dev/fd/*. It refuses a target that starts with $ or uses $(, ${ or backticks, a glob, a brace or a backslash, an overlong path, a path through a symlink, and any command over 64 KB.
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.
