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 | $0.01216 | $0.01216 |
| Opus 5.5 | $0.00486 | $0.00486 |
| Sonnet 5.5 | $0.00243 | $0.00243 |
| Haiku 4.5 | $0.00122 | $0.00122 |
Grade A, and why
artifacty 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 4d 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 — 73 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 when working with this repository.
Artifacty is a local, agent-to-agent artifact exchange for LLM workflows. One agent publishes an artifact. Other agents can list, read, import, update, and continue from it without copying content through chat. HTTP, the browser, the CLI, and MCP stdio use the same store.
See AGENTS.md for repository structure, coding-style conventions, and commit/PR guidelines.
For English and Korean documentation, follow the writing style guide. Apply relaxed STE-100 clarity principles to both languages. Preserve conditions, defaults, permissions, exceptions, and recovery requirements. For Korean, apply fluent-korean as well; resolve conflicts in this order: technical accuracy, natural Korean, then brevity and sentence form. Follow its required documentation workflow: update both languages, capture and inspect English UI screenshots for browser workflows, run npm run docs:check, verify changed examples in isolated stores, and report validation limits.
Commands
npm test— run all tests withnode --test.npm run lint— syntax-check source and tests withnode --check.npm run smoke— start a temporary token-protected server and verify core HTTP, backup, and MCP behavior.npm run release:check— run lint, tests, and smoke together.npm start— run the HTTP dashboard. It prefers127.0.0.1:8787and falls back when the default port is busy.node src/mcp-server.jsornpm run mcp— run the MCP stdio server.node src/cli.js help— inspect CLI usage.
Run npm run release:check before claiming a release-ready change. The server runs plain ESM directly on Node >=22.12.0. Generated UI assets are committed, so ordinary startup needs no build. After changing src/styles/ui-controls.scss or the icon set in scripts/build-ui.mjs, run npm run build:ui and include the generated assets.

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.
