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 | $0.00890 | $0.00890 |
| Opus 5 | $0.00445 | $0.00445 |
| Sonnet 5 | $0.00178 | $0.00178 |
| Haiku 4.5 | $0.00089 | $0.00089 |
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 — 65 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 once; others list, read, import, update, and continue from it without copying content through chat. It exposes one shared store over HTTP/browser, CLI, and MCP stdio surfaces.
See AGENTS.md for repository structure, coding-style conventions, and commit/PR guidelines.
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. There is no build step; this is plain ESM run directly by Node >=22.5.
Architecture
Shared Library Funnel
The three entry points are thin adapters:
src/server.jshandles HTTP/browser routes and JSON API.src/cli.jshandles command-line workflows.src/mcp-server.jshandles MCP JSON-RPC over stdio.
Shared behavior belongs in src/lib/*. Storage logic lives in src/lib/storage.js, conversion logic in src/lib/converters.js, installer logic in src/lib/installer.js, security checks in src/lib/security.js, and server URL discovery in src/lib/server-state.js.
Storage Model
The store lives at ARTIFACTY_HOME or ~/.artifacty by default.
- SQLite metadata is stored in
artifacty.sqlite. - Immutable version files are stored under
artifacts/<id>/v<n>.<ext>. server.jsonrecords the currently running browser server URL so CLI and MCP responses keep working when the default port falls back.- Legacy
index.jsonstores migrate automatically on first access.
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.
