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 | $0.00095 | $0.04909 |
| Opus 5 | $0.00048 | $0.02455 |
| Sonnet 5 | $0.00019 | $0.00982 |
| Haiku 4.5 | $0.00010 | $0.00491 |
Grade A, and why
us-market-bubble-detector 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 2d 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.
This is a copy
100% identical to us-market-bubble-detector — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

US Market Bubble Detection Skill (Revised v2.1)
Key Revisions in v2.1
Critical Changes from v2.0:
- ✅ Mandatory Quantitative Data Collection - Use measured values, not impressions or speculation
- ✅ Clear Threshold Settings - Specific numerical criteria for each indicator
- ✅ Two-Phase Evaluation Process - Quantitative evaluation → Qualitative adjustment (strict order)
- ✅ Stricter Qualitative Criteria - Max +3 points (reduced from +5), requires measurable evidence
- ✅ Confirmation Bias Prevention - Explicit checklist to avoid over-scoring
- ✅ Granular Risk Phases - Added "Elevated Risk" phase (8-9 points) for nuanced risk management
When to Use This Skill
Use this skill when:
English:
- User asks "Is the market in a bubble?" or "Are we in a bubble?"
- User seeks advice on profit-taking, new entry timing, or short-selling decisions
- User reports social phenomena (non-investors entering, media frenzy, IPO flood)
- User mentions narratives like "this time is different" or "revolutionary technology" becoming mainstream
- User consults about risk management for existing positions
Japanese:
- ユーザーが「今の相場はバブルか?」と尋ねる
- 投資の利確・新規参入・空売りのタイミング判断を求める
- 社会現象(非投資家の参入、メディア過熱、IPO氾濫)を観察し懸念を表明
- 「今回は違う」「革命的技術」などの物語が主流化している状況を報告
- 保有ポジションのリスク管理方法を相談
Evaluation Process (Strict Order)
Phase 1: Mandatory Quantitative Data Collection
CRITICAL: Always collect the following data before starting evaluation
1.1 Market Structure Data (Highest Priority)
□ Put/Call Ratio (CBOE Equity P/C)
- Source: CBOE DataShop or web_search "CBOE put call ratio"
- Collect: 5-day moving average
□ VIX (Fear Index)
- Source: Yahoo Finance ^VIX or web_search "VIX current"
- Collect: Current value + percentile over past 3 months
□ Volatility Indicators
- 21-day realized volatility
- Historical position of VIX (determine if in bottom 10th percentile)
1.2 Leverage & Positioning Data
□ FINRA Margin Debt Balance
- Source: web_search "FINRA margin debt latest"
- Collect: Latest month + Year-over-Year % change
□ Breadth (Market Participation)
- % of S&P 500 stocks above 50-day MA
- Source: web_search "S&P 500 breadth 50 day moving average"
What ships with it
7 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.
