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

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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/bubble_scorer.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

US Market Bubble Detection Skill (Revised v2.1)

Key Revisions in v2.1

Critical Changes from v2.0:

  1. Mandatory Quantitative Data Collection - Use measured values, not impressions or speculation
  2. Clear Threshold Settings - Specific numerical criteria for each indicator
  3. Two-Phase Evaluation Process - Quantitative evaluation → Qualitative adjustment (strict order)
  4. Stricter Qualitative Criteria - Max +3 points (reduced from +5), requires measurable evidence
  5. Confirmation Bias Prevention - Explicit checklist to avoid over-scoring
  6. 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"

Changes

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.
