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 | $0.06756 | $0.06756 |
| Opus 5 | $0.03378 | $0.03378 |
| Sonnet 5 | $0.01351 | $0.01351 |
| Haiku 4.5 | $0.00676 | $0.00676 |
Grade A, and why
geeklego 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 10d 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 — 355 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.
This is the GeekLego v2 system: 2-tier tokens (primitives → semantics) + ShadCN/Radix components. It replaces the old 3-tier (primitive → semantic → component-token) architecture. The 2-tier cut has landed and the Token Editor
app/has been rebuilt on v2 — see "Repo state" below. The reference implementation for every v2 rule in this file is the Button slice at components/v2/Button/ — read it before building anything.This file is the authoritative source for v2 rules. Read it together with the reference component above.
What is GeekLego (v2)?
GeekLego is an open-source, design-system-first React component library built on Tailwind CSS v4 + ShadCN/Radix UI.
It ships:
- A 2-tier design system —
design-system/v2/— primitives (geeklego's brand palette/scales, unchanged) aliased to a standard ShadCN/Tailwind semantic vocabulary (--primary,--background,--border,--ring, …). Components consume the semantics directly. - A component library —
components/v2/— ShadCN-pattern React components (cvavariants +cn()+ Radix primitives) styled with standard semantic utilities (bg-primary text-primary-foreground). - An AI generation skill —
component-builder-v2— generates new v2 components following the rules below. - A token editor → cockpit (
app/) — edit primitives + semantics, manage themes, export to CSS / IR / design.md. (Being adapted from 3-tier; see brief §4.)
Design-system-first means: the token system (primitives + semantics) is the source of truth. Components are an expression of it — you never hardcode a value or invent vocabulary. You consume the standard semantics, and only reach for namespaced --ext-* tokens for genuine brand-custom variants.
Why standard ShadCN vocabulary? Industry-standard, in every LLM's training set, native Tailwind v4 utilities, paste-and-go. The only geeklego-specific layer is the primitive palette (the brand seam) — the semantic interface is deliberately standard.
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.

geeklego CLAUDE.md is an instructions file published in the GitHub repository GeekyAnts/geeklego (5 stars, last pushed 2mo ago), licensed MIT. It adds 6,756 tokens to every session, about $0.0338 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.
