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 | $0.01889 | $0.01889 |
| Opus 5 | $0.00945 | $0.00945 |
| Sonnet 5 | $0.00378 | $0.00378 |
| Haiku 4.5 | $0.00189 | $0.00189 |
Grade A, and why
agent-atlas-studio 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 9d 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 — 81 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.
What this is
agent-atlas-studio is an Erwin-style visual modeler for agentic AI systems. You lay out a whole platform — orchestrator, tasks, agents, MCP tools, jobs, routers, and systems (datastores) — as one unified, collapsible graph, validate each object live against the agent-atlas JSON schema, and export a versioned registry of YAML manifests.
It runs identically as a static web build (GitHub Pages) and a local-first Tauri 2 desktop app. No backend, no auth, no cloud dependency.
Commands
npm install # requires submodule: git submodule update --init
npm run dev # web dev server → http://localhost:5173
npm run build # static build → dist/
npm run preview # serve the production build
npm run lint # eslint .
npm run tauri dev # desktop app (runs `npm run dev` first, loads localhost:5173)
npm run tauri build # package the desktop app (runs `npm run build` first)
There is no test runner configured. npm run lint (ESLint flat config in eslint.config.js) is the only automated check.
The GitHub Pages build sets BASE_PATH=/agent-atlas-studio/ so assets resolve on the project-pages subpath; dev and the Tauri build use base: '/' (see vite.config.js).
The submodule is the source of truth — do not duplicate the schema
vendor/agent-atlas is a git submodule (Fox-River-AI/agent-atlas) holding the canonical manifest schema and deterministic validators. The point of vendoring it is that there is exactly one copy of the spec, so the UI can never drift from it.
src/atlas/schema.jsimports schemas and compiles Ajv validators. Thetoolschema is imported straight from the submodule (vendor/agent-atlas/registry/schema/tool.schema.json). Theagent,job,system,router, andorchestratorschemas live insrc/atlas/schemas/*.json— these are prototyped in-studio for fast iteration and meant to be upstreamed to agent-atlas once proven. When changing object shapes, edit the studio schema, but treat the submodule tool schema as canonical.- Schemas declare JSON Schema draft 2020-12, so
schema.jsimportsajv/dist/2020(the default Ajv export only knows draft-07 and will throw atcompile()). - The registry export (
src/atlas/model.js) is built to satisfy agent-atlas's owngovernance/ci/validate_registry.py, so the same checks that gate the OSS repo gate what this UI produces.
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.

agent-atlas-studio CLAUDE.md is an instructions file published in the GitHub repository Fox-River-AI/agent-atlas-studio (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 1,889 tokens to every session, about $0.0094 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.
