Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00333 | $0.03032 |
| Opus 5 | $0.00167 | $0.01516 |
| Sonnet 5 | $0.00067 | $0.00606 |
| Haiku 4.5 | $0.00033 | $0.00303 |
Grade A, and why
tej-variable-mapper 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 5d 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.

TEJ 變數映射師（Variable Mapper）
Step 1｜解構文獻變數定義（先寫給人看）
逐一列出文獻中每個變數（Y / X / 調節 / 中介 / 控制）的：
- 原始文字定義與計算公式（照抄文獻，不要自己改寫語意）。
- 原始資料庫代碼：Compustat item（如總資產 AT、普通股權益 CEQ、淨利 NI、Item 6）或 CRSP 欄位（RET、PRC×SHROUT 算市值）。
- 測量頻率與單位（年/季；千元/百萬；原幣別）。 若文獻只給文字沒給代碼，標「推測代碼：AT」並註明「依 Compustat 慣例推測，使用者宜對照原文附錄確認」。
Step 2｜映射到 TEJ 欄位（核心，內建不編造防線）
每個變數對到 TEJ：
- 模組與表：如「企業財務→IFRS 以合併為主簡表(累計)-全產業，文件代碼 wim1a」；治理變數→「TEJ 公司治理／董監股東」；報酬→「TEJ 股價資料庫→股價報酬(日)」。路由不確定時，先用 tej-data-scout 的 catalog 定位，再往下。
- 具體欄位名稱與代碼：只有在你確知（對得上 catalog、tejdoc 文件、或使用者提供）時才寫死代碼（如資產總額 T0010）。只要不確定，一律寫「推測：TEJ 應有對應『資產總額』欄位，代碼需在 TEJ 介面『資料說明』鈕或 tejdoc
wim1a.html確認」——絕不編造像 T0xxx 的代碼。 編造的代碼會在下載階段才爆，浪費使用者時間。 - 可得性分級（沿用 scout 語言）：【直接】TEJ 有現成欄位／【衍生】TEJ 有原料需自算／【外部】TEJ 無需另尋。
Step 3｜落差與代理方案（GAAP↔IFRS、資料庫慣例差異）
逐變數警告可能的衡量誤差，並給代理：
- 會計準則：美國 US GAAP vs 台灣 IFRS 的科目定義差（研發費資本化與否、商譽、租賃、非常項目、合併範圍）。
- 資料庫慣例：Compustat 期末 vs TEJ 期末認定、市值算法（CRSP 用 PRC×SHROUT，TEJ 有現成市值欄位但股本/庫藏處理可能不同）、報酬是否已調整除權息（TEJ 有「調整」與「未調整」兩套，選錯整條報酬序列作廢）。
- 無現成欄位時的代理：如 Tobin's Q，TEJ 無現成欄位，給近似式 (市值＋負債帳面)/總資產，並列出各分子分母對到哪個 TEJ 欄位。
Step 4｜三欄對照表 + 假說對帳表（輸出，見 output_contract）
先產出「假說→變數→資料欄位」對帳表（L-002 防線），確認每個假說用到的變數都在表中、無遺漏、無一變數被誤用到兩個假說；再產出三欄映射對照表。
<output_contract> 兩張表，缺一不可：
表一：假說→變數→資料欄位對帳表（L-002 防呆）
| 假說 | 角色 | 變數名 | TEJ 欄位/代碼 | 可得性 | 對帳狀態 |
|---|---|---|---|---|---|
| H1 | X | 家族控制 | 控制持股與結構（待確認欄位） | 衍生 | 需自訂操作型定義 |
| 用途：確保每個假說的每個變數都對得到一個且僅一個資料來源；一變數被兩個構念共用時紅旗（正是 L-002 「RPT 誤代 TNFD 虛擬變數」的病根）。 |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

tej-variable-mapper is a skill published in the GitHub repository Nero1688/claude-academic-skills (6 stars, last pushed 7d ago), licensed MIT. It adds 333 tokens to every session and 3,032 once invoked, about $0.0017 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.
