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 | $0.00069 | $0.00638 |
| Opus 5 | $0.00034 | $0.00319 |
| Sonnet 5 | $0.00014 | $0.00128 |
| Haiku 4.5 | $0.00007 | $0.00064 |
Grade A, and why
buy-back-your-time 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.
What it actually says
Buy Back Your Time — 时间买回策略
富人用钱买时间。穷人用时间换钱。你的目标：从后者变成前者。
Dan Martell 的核心主张：任何低于你时薪 1/4 的任务都应该外包。 你在高价值活动上每小时值 $100？那 $25/小时以下的任务就别自己做。
时间买回公式
算出你的时薪 → 把低于时薪 1/4 的任务外包 → 把省下的时间投入更高价值的事
第一步：算你的真实时薪
年收入 ÷ 年工作小时数。如果你做副业年赚 10 万，花了 1000 小时，时薪 = $100。
第二步：识别可外包任务
列出你这周做的所有事，按两个维度分类：
| 高价值 | 低价值 | |
|---|---|---|
| 只有你能做 | 做（核心） | 简化或砍掉 |
| 别人也能做 | 培训后委托 | 立即外包 |
第三步：外包
- 虚拟助理：邮件、日程、客服
- 自由职业平台：设计、开发、写作、翻译
- 自动化工具：支付、邮件营销、排程
第四步：把省下的时间投入高价值
不是放假——是去做你每小时值 $100 的事。
三个心理障碍
- 「我自己做更快」 —— 第一次是。第十次不是。外包需要前期投入，回报在后期。
- 「外包太贵了」 —— 想想你的时薪。你花 2 小时做一件 $20 就能外包的事 = 你亏了。
- 「别人做不好」 —— 那是你没说清楚。写清楚标准，第一次检查，之后放手。
一句话总结
你的时间值钱，别拿它换零钱。买回你的时间，然后把它花在只有你能做的、最有价值的事上。
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.

buy-back-your-time is a skill published in the GitHub repository muyuhill/100books-to-skills (12 stars, last pushed 2mo ago), licensed MIT. It adds 69 tokens to every session and 638 once invoked, about $0.0003 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 2026-08-30.
