Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

任意のアプリのコードベースを解析して LLM API 呼び出し箇所を洗い出し、「1 回の処理(フロー)で どれだけのトークン/費用がかかるか」「N 件・DAU 規模でいくらか」を根拠付きで試算するスキル。 プロンプト/ツール定義/RAG/エージェントループ/キャッシュ/思考トークンまで合算し、無料 or 確認付き 有料の実測でグラウンディングする。成果物は Markdown レポート + 対話 HTML 計算機 + コスト JSON。 「このアプリの API コストはいくら」「モデル別/件数別の費用」「LLM の ROI 試算」「トークン数を数えて」 「1リクエストいくら」等で起動。既定スタックの必須スキルではない optional 群であり、AI 機能を含む要件で明示された場合、 または app-orchestrator が v1 前・AI 機能変更時の試算として指示した場合のみロードする。

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'llm-cost-simulator' ] || [ -L ~/.agents/skills/'llm-cost-simulator' ]; then echo 'A skill folder named llm-cost-simulator already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/daishiman/harness-dev' "$d" && git -C "$d" checkout --quiet '3e1b394bd699e07d0b030acd44ee12f9143f89eb' -- '.agents/skills/llm-cost-simulator' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/llm-cost-simulator' ~/.agents/skills/'llm-cost-simulator' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'llm-cost-simulator' ~/.claude/skills/'llm-cost-simulator' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
