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 | $0.02575 | $0.02575 |
| Opus 5.5 | $0.01030 | $0.01030 |
| Sonnet 5.5 | $0.00515 | $0.00515 |
| Haiku 4.5 | $0.00258 | $0.00258 |
Grade A, and why
melta-ui AGENTS.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 12d 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 — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
melta UI — AI エージェント作業ガイド
AI coding agents（Claude Code / Codex / Cursor / Gemini CLI 等）共通の作業指示 SSOT。 デザイン仕様は
DESIGN.md、exact value はdesign/contracts/を参照。 Claude Code 固有の挙動（PostToolUse hook / MCP 自動接続 / skills）はCLAUDE.md。 Cursor 固有の入口は.cursor/（MCP 設定のmcp.jsonと、所在ポインタのrules/melta-ui.mdc）。仕様・値は置かない。
アーキテクチャ概要
この DS は 3 層構造（AI-Ready 2.0）で運用されている。
- Layer 1: 憲法 —
DESIGN.mdが AI 向け入口。原則 + Quick Reference。これだけで基本 UI を生成可能 - Layer 2: 仕様 —
design/contracts/に 40 contract（web 28 + app 先行 12）+ 107 禁止ルール + 101 トークンの JSON 仕様。これが SSOT - Layer 3: 検証 —
scripts/design/の harness が Schema 整合・drift・a11y を自動検証。CI + hook で守る
詳細:
design/authority.md（SSOT 宣言・値競合時の優先順位）、README.md（全体構造）

作業ルール
- UI タスク開始時に
DESIGN.mdを読む - exact value が必要なら
design/contracts/を参照する - コンポーネント仕様は
*.contract.jsonを優先（なければcomponents/*.md→metadata/components.json） - 禁止ルールの SSOT は
design/contracts/rules.json（107 ルール） - finish 前に
npm run design:checkとnpm run design:lint-generated -- <生成ファイル>を走らせる - generated file（
metadata/components.json、llms.txt/llms-full.txt、design/contracts/recipes/web/）を直接編集しない →npm run design:buildで再生成 - 新しい component を作る場合、まず
design/contracts/components/に contract を書く - loop / pipeline / CI 自動修復を扱う場合は
docs/melta-loop-playbook.mdを読む。SSOT write、baseline 緩和、test 弱体化、publish/deploy は human gate - recipes の2層規約:
recipes/web/= 契約から生成される導出ミラー（編集禁止）/recipes/app/= RN styleRefs の手書き authoring source。app recipe の値は{"token": "<tokens.json ノードパス>"}か literal（色の hex 直書き禁止）。variants / sizes / states のキーは契約の部分集合（語彙の発明はdesign:checkが error）。契約を変えたらdesign:compat（npm 公開版との互換ゲート）が semver bump を要求する
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.

melta-ui AGENTS.md is an instructions file published in the GitHub repository tsubotax/melta-ui (202 stars, last pushed 12d ago), licensed MIT. It adds 2,575 tokens to every session, about $0.0103 per session on Opus 5.5. 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.
