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 | $0.00180 | $0.02297 |
| Opus 5 | $0.00090 | $0.01149 |
| Sonnet 5 | $0.00036 | $0.00459 |
| Haiku 4.5 | $0.00018 | $0.00230 |
Grade A, and why
serenity-method 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.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Serenity Method
A distilled, reusable version of how Serenity (@aleabitoreddit) analyzes equities. Use it to analyze any stock, supply chain, or market situation — not only her feed. It captures her method, not her positions.
This skill is method only. It does not fetch data. To pull her live posts or build mention analytics, use the separate follow-aleabito skill; you can feed its output into this method, but this skill works standalone on any company you research yourself.
One-line summary of the method: find the real bottleneck, reason from first principles, gate it through Buffett-style quality questions, separate narrative from fundamentals, and label the result a research lead — not a buy.
When to use
- "Analyze $X the way Serenity / aleabito would."
- "Is $X a critical chokepoint? Map its supply chain."
- "Give me a first-principles + Buffett judgment on $X."
- Turning a Serenity post (or any thesis) into a structured, beginner-friendly analysis (中文 or English).
What you produce
Language / 语言: respond in the user's language — 中文 by default, English when the request is in English or the user asks. The structure is identical in both; bilingual block labels are shown below.
For each ticker or theme, output these blocks, beginner-friendly, defining jargon on first use (see references/glossary.md):
- 核心论点 / 她的观点 · Core thesis / Her view — the one-paragraph thesis (if analyzing a Serenity post, ground it in the post + cite the source URL; if analyzing your own idea, state it plainly).
- 小白解释 · Plain-language — re-explain in plain language a beginner can follow.
- 第一性原理 · First principles — decompose with the five levers (Step 2).
- Buffett 直接判断 · Buffett verdict — answer the five fields (Step 3). Answer them, do not pose them as questions.
- 当前结论 · Conclusion — classify:
研究地图 / research-map(a lead worth tracking)vs可投资结论 / investable-conclusion(only after moat + financials + valuation + margin-of-safety work). Default to研究地图.
What ships with it
3 files 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.
