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 | $0.04670 | $0.04670 |
| Opus 5.5 | $0.01868 | $0.01868 |
| Sonnet 5.5 | $0.00934 | $0.00934 |
| Haiku 4.5 | $0.00467 | $0.00467 |
Grade A, and why
ai-setup 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 15d 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

What this repo is
Public, opinionated Claude Code defaults for Node.js / TypeScript projects. It ships subagents, user-invocable slash commands, a permissions baseline, and a CLAUDE.md template that users drop into consumer projects. No consumer application code and no build step. It does have a test suite: POSIX shell harnesses under tests/ covering the installer, the rule globs, the skills allowlist, the shipped commands' hardening (config-hardening), who owns each ~/.claude path (claude-config-ownership) and the loopd rename's pinned survivor list — run them all before pushing. So work here is markdown and JSON under .claude/, the top-level README.md, shell under tests/, .claude/hooks/, .claude/scripts/ and install.sh, and one small standalone app — the theme previewer under themes/preview-app/ (dependency-free Node server + static HTML/CSS/ES modules, no package.json, no build). .github/ holds one CI workflow that runs that suite on every PR, and the required-checks.txt naming it. This sentence used to read "no test suite … markdown and JSON", which was true when it was written and has been false for a while; a reviewer reading it as policy asked for shell changes to be removed. If you add a new kind of file here, fix this line in the same commit.
This repo owns ~/.claude
Two installers used to claim ${CLAUDE_CONFIG_DIR:-~/.claude}: this one, and the config/
layer of cbmono/ai-bridge, which was a fork of this .claude/ tree. 24 of 26 entries
were shipped by both and 14 had diverged, so ownership was decided by whichever installer
ran last. The cost was not cosmetic: fixes made in the private fork — including two
secret-exposure paths — sat there for weeks while this public repo shipped the defects.
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.
