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 | $0.00148 | $0.01612 |
| Opus 5 | $0.00074 | $0.00806 |
| Sonnet 5 | $0.00030 | $0.00322 |
| Haiku 4.5 | $0.00015 | $0.00161 |
Grade A, and why
serenity-chokepoint-investing 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.

Serenity Chokepoint Investing
Core Stance
Use this skill to produce research, not financial advice. Treat Serenity's public record as a pattern library: supply-chain mapping, bottleneck detection, Bayesian evidence updating, asymmetric mispricing, and explicit evidence tracking. Do not imitate identity, certainty, returns, or promotional tone.
Always browse or otherwise verify current market facts when prices, filings, laws, customers, supply relationships, or recent catalysts matter. For live analysis, fetch company news and official announcements unless the user explicitly asks for a historical/theoretical framework only. Label inference, rumor, and unverified trade disclosure clearly.
Workflow
- Identify the listing market. Normalize ticker, exchange, reporting currency, filing regime, trading liquidity, and information sources before analysis.
- Fetch current news and official disclosures. Gather recent announcements, filings, earnings, customer/supplier news, subsidies, index/listing events, dilution/financing, and credible negative reports. Use
references/market-data-and-news.mdfor source priority by market. - Define the end-demand shock. Name the large demand wave: AI clusters, CPO, 800VDC, data-center power, photonics, memory, sovereign supply chains, robotics, or another concrete buildout.
- Map the physical chain backward. Trace from buyer/system to module, component, material, equipment, foundry, substrate, chemical, or capacity owner. Prefer BOMs, filings, presentations, standards docs, patents, customer qualification language, and government supply-chain documents.
- Set the prior. State the initial probability that this company is a true bottleneck. Anchor the prior in physical reality: BOM role, customer need, capacity, substitutes, and company scale.
- Dig down at least three layers. Do not stop at the obvious bottleneck. Move from GPU/HBM/power/network into second- and third-order nodes: laser sources, substrates, crystal growth equipment, testing, packaging, fiber, chemicals, tools, and overlooked system integrators.
- Find the chokepoint. Identify where supply is scarce, slow to expand, architecturally specific, or concentrated. Look for quasi-monopoly share, proprietary process, qualification cycles, national-security status, or upstream material dependence.
- Translate demand into financial impact. Ask whether the same demand shock is immaterial to mega-caps but material to this smaller company. Estimate revenue, margin, backlog, or multiple impact.
- Test market access and pricing vacuum. Check market cap, analyst coverage, liquidity, float, short interest, institutional ownership constraints, index/listing events, and whether large funds are structurally unable to own the name before the rerating.
- Test mispricing. Compare the chokepoint's future relevance with current market attention, market cap, book value/replacement value, forward earnings scenarios, balance sheet risk, liquidity, dilution, and ownership structure.
- Update with evidence. Treat new filings, earnings, customer wins, subsidies, technical validation, short reports, dilution, and failed ramps as Bayesian evidence that raises or lowers conviction.
- Track capital rotation. Identify whether institutions are rotating from first-order winners into second-order suppliers, for example memory -> optical modules -> external light sources / silicon photonics.
- Score the setup. Use the rubric in
references/research-rubric.mdwhen the user asks for a formal analysis or when multiple candidates are compared. - Separate trade from thesis. Record only explicit trade disclosures as trades. Treat "bullish", "favorite", "compelling", price targets, and sector lists as thesis or watchlist unless the source says bought/went long/took positions/adding/sold/trimmed/own/hold.
- Write the output with evidence levels. Include strongest evidence, weakest link, near-term catalysts, disconfirming evidence, and what would change the thesis.
What ships with it
4 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.

serenity-chokepoint-investing is a skill published in the GitHub repository xvhaoran778-cyber/Serenity.SKILL (52 stars, last pushed 3mo ago), licensed MIT. It adds 148 tokens to every session and 1,612 once invoked, about $0.0007 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.
