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 | $0.00681 | $0.00681 |
| Opus 5 | $0.00341 | $0.00341 |
| Sonnet 5 | $0.00136 | $0.00136 |
| Haiku 4.5 | $0.00068 | $0.00068 |
Grade A, and why
claude-copy 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.
How it starts
The opening of the file, as written. The whole thing — 32 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codebase Overview
This repo is a design-cloning workshop: a Chrome extension captures a website's screenshot/DOM/computed styles, and a clone pipeline turns that into a clone verified pixel-by-pixel against the screenshot. Each cloned site lives in apps/<site>/ — capture inputs, derived shared/ design system, one folder per route, and progress.md as the handoff record.
Stack: vanilla Python (PIL/Playwright on the system python3) for the measuring oracle; React + Vite + Tailwind v4 + shadcn/ui for the React clone target; Chrome Manifest V3 (capture-extension/).
Structure: apps/<site>/ (one folder per cloned site) · capture-extension/ (capture tool) · .claude/skills/ (clone — the pipeline, a plugin; plus plugin-creator, dense-ui-metrics, shadcn, skill-creator).
The clone plugin
.claude/skills/clone/ is a Claude Code plugin (clone@skills-dir, auto-loads from this repo). It ships two skills over one engine:
/clone:html— staticpage.htmlroutes, no toolchain/clone:react— shadcn/ui components with captured states as props
One CLI, on PATH as clone while the plugin is enabled:
clone prep <session> --target html|react # target is recorded in routes.json
clone extract | resolve | cluster | check
clone init | map | build # react only
The engine is engine/ — one module per concern (prep, extract, glyphs, assets, cluster, score, check, progress, styles, util), with the two artefacts as engine/targets/{html,react}.py behind a Target interface. Adding a third artefact means one file in targets/, not a fork. Shared pipeline docs live in references/pipeline.md; both skills point at it rather than restating it.
Tests (clone/tests/): test_engine.py, test_react.py, test_hook.py (fast), test_e2e.py (runs every phase as a subprocess against a real capture). Run all four after touching the engine.
A PreToolUse hook (hooks/guard.py) blocks scripted rewrites (python3 - <<, sed -i, perl -pi) of clone artefacts. Use Edit — a .replace() that does not match is a silent no-op, and one measured session made 50 such edits believing they landed.
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.

claude-copy CLAUDE.md is an instructions file published in the GitHub repository HarKro753/claude-copy (17 stars, last pushed 1mo ago), licensed MIT. It adds 681 tokens to every session, about $0.0034 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 2026-08-30.
