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 | $0.05002 | $0.05002 |
| Opus 5.5 | $0.02001 | $0.02001 |
| Sonnet 5.5 | $0.01000 | $0.01000 |
| Haiku 4.5 | $0.00500 | $0.00500 |
Grade A, and why
hyperclaude 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 24d 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 — 134 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.
What this repo is
hyperclaude is a Claude Code plugin that pairs Claude (builder) with Codex (critic) via a thin Node script. Claude implements, Codex reviews — that is the default role split; when Codex usage runs ahead of its rate-limit window, a loop seats an adversarial Claude reviewer agent instead (references/reviewer-seat.md). Codex is always invoked with read-only sandbox; never let it author patches.
The plugin is meant to be installed into Claude Code (/plugin install hyperclaude); when you're editing this repo, you're editing the plugin source itself.
Commands
Prerequisites: Node 18+, codex-cli >= 0.130.0 on PATH, git. No npm install step — stdlib only.
node --test tests/*.mjs # unit tests (shared fixtures live in tests/helpers/,
# outside the glob). NOTE: `node --test tests/` (dir
# form) does NOT work — it interprets the path as a
# test name and fails.
node --test tests/codex-args.test.mjs --test-name-pattern "<regex>"
# single test by name
bash scripts/test/smoke.sh # acceptance smoke: dry-runs, manifest, hook, codex probes
node scripts/codex-bridge.mjs <mode> --dry-run [flags]
# exercise the bridge without spawning codex
Both test commands must pass before tagging a release. Zero npm dependencies — do not introduce any.
Local dev install (dogfooding)
To exercise skill/agent edits live inside Claude Code, symlink the repo into the plugin cache. Use the version from .claude-plugin/plugin.json as the leaf:
version=$(node -e 'console.log(require("./.claude-plugin/plugin.json").version)')
ln -s "$(pwd)" ~/.claude/plugins/cache/hyperclaude/hyperclaude/"$version"
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.

hyperclaude CLAUDE.md is an instructions file published in the GitHub repository zeikar/hyperclaude (5 stars, last pushed 16d ago), licensed MIT. It adds 5,002 tokens to every session, about $0.0200 per session on Opus 5.5. 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.
