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.

What it costs to keep this loaded
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 | $0.00089 | $0.01978 |
| Opus 5 | $0.00044 | $0.00989 |
| Sonnet 5 | $0.00018 | $0.00396 |
| Haiku 4.5 | $0.00009 | $0.00198 |
Grade A, and why
china-nav-tieout 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 13d 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.

Workflow
Step 1: Gather Portfolio Holdings
Holdings snapshot:
| Security | Ticker | Type | Quantity | Market Value | Cost | Unrealized P/L |
|---|---|---|---|---|---|---|
| Cash | ||||||
| Receivables | ||||||
| Payables | ||||||
| Total NAV |
Step 2: Value Each Holding
Valuation methodology:
| Security Type | Valuation Method | Source |
|---|---|---|
| A股上市股票 | Closing price (收盘价) | 交易所 |
| A股停牌股票 | Last closing / 估值 | 中基协 guidelines |
| 基金 (ETF/LOF) | NAV / market price | 基金公司 |
| 债券 | 中债估值 / 收盘价 | 中债/交易所 |
| 逆回购 | Principal + interest | Calculated |
| 存款 | Principal + interest | Bank |
| 衍生品 | Mark-to-market | Exchange/Counterparty |
A-share valuation rules:
- 上市股票: 收盘价 (closing price)
- 停牌股票:
- <1 month: last closing
- 1-3 months: 中基协 AMAC guidelines
-
3 months: independent valuation
- 涨跌停股票: Ceiling/floor price
Step 3: Calculate NAV
NAV calculation:
| Component | Amount | Notes |
|---|---|---|
| Market value of securities | ¥XX | |
| Cash and cash equivalents | ¥XX | |
| Accrued income | ¥XX | Dividends, interest |
| Receivables | ¥XX | |
| Other assets | ¥XX | |
| Gross Assets | ¥XX | |
| Payables | ¥XX | |
| Accrued expenses | ¥XX | Management fees, etc. |
| Other liabilities | ¥XX | |
| Total Liabilities | ¥XX | |
| Net Assets | ¥XX | |
| Shares outstanding | XX 份 | |
| NAV per share/unit | ¥X.XXXX |
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.
