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 | $0.01621 | $0.01621 |
| Opus 5.5 | $0.00648 | $0.00648 |
| Sonnet 5.5 | $0.00324 | $0.00324 |
| Haiku 4.5 | $0.00162 | $0.00162 |
Grade A, and why
agent-atelier 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 — 76 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 repo is
Agent Atelier — a multi-plugin Claude Code marketplace, not an application. It curates Big Emotion's first-party skills, commands, and agents into six domain plugins under plugins/, distributed as the git repo itself (/plugin marketplace add big-emotion/agent-atelier; the marketplace name stays big-emotion, so installs are <plugin>@big-emotion). There is no build, no runtime, no deploy.
Almost everything here is Markdown. The only executable code is the two CI gates — scripts/check-templates.mjs and scripts/check-manifests.mjs — and their tests.
Registry layout
| Plugin | Contents |
|---|---|
plugins/prompt-utils |
skills expertify, thought, repo-scout + command interview |
plugins/project-standard |
the setup skill: the seven-module Big Emotion project standard (M1–M7) with runbooks and templates |
plugins/pr-trains |
skills review-train, fix-train, fix-ci-train, merge-train, issue-train |
plugins/frontend-fidelity |
skills reverse-ui, blueprint, validate-fidelity |

skill ai-code-tells, agent code-review (+ codex/code-review.toml, the Codex CLI variant) |
plugins/agent-comms |
skills attention-architect, video-director, audience-audit, content-strategist, bigemotion-reel-clip |
Every plugin is generic by construction: no client names, no infrastructure coordinates, no secrets. New material must arrive already de-branded.

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.
