Token cost

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.

Security

Grade A, and why

v10-基金投资入门 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 11d 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.

What it actually says

基金投资入门

R(核心引文)

"基金就像一口大锅,许多投资人把钱投进去。因为这些人没有时间,没有相关的知识或者没有兴趣去亲自买股票。这口锅里的钱交给金融界的专家,也就是所谓的基金经理人,去投资买股票。"

"如果我们打算投资买基金,就要准备把自己的钱在里面放上 5 到 10 年。对于那些能等这么长时间的人来说,基金几乎是一种零风险的投资。"

"挑选基金时的注意事项:1. 基金应该至少有十年历史。2. 应该选择大型的跨国股票基金。3. 对基金的走势图进行比较。"

I(底层原理)

基金通过分散投资(至少20种股票)降低了单只股票风险。基金经理的专业管理让普通人无需深入研究个股。长期持有(5-10年)是基金盈利的关键——短期波动会被时间熨平,市场总体趋势向上。

A1(过去应用)

金钱魔法师们选择了一个专门针对儿童的基金(投资可口可乐、玩具翻斗城、迪斯尼、麦当劳等),该基金过去10年年均收益15.42%。她们用2万马克买入,后来下跌时没有恐慌卖出,最终获得丰厚回报。

A2(未来触发场景)

  • 你有一笔3年以上不用的闲钱想投资时
  • 你不想花时间研究个股但想参与股市增长时
  • 你想为孩子准备教育金或自己的养老金时
  • 你被推荐某只基金需要评估时

E(执行步骤)

  1. 确认这笔钱5-10年内不需要动用
  2. 选择有10年以上历史的大型跨国股票基金
  3. 比较过去5-10年的走势图和年化收益率
  4. 通过正规基金公司或银行开户
  5. 定投或一次性投入后,不要频繁查看涨跌
  6. 坚持持有,只在重大人生目标实现时考虑赎回

B(边界与局限)

基金不是保本产品,短期(1-2年)可能出现亏损。基金经理的能力参差不齐,选错基金可能跑输市场。基金有管理费,费率差异会影响长期收益。基金适合做长期配置,不适合短期投机。

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.
