Claude Trading Skills is a collection of Claude Code workflows for individual investors who want structured market analysis, charting, economic-calendar review, screening, trade planning, journaling, and risk management. It is designed for people using long-term investing, ETFs, dividend stocks, and disciplined swing trading, and the catalogue entries package these workflows as skills, agents, commands, settings, and instructions.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00071 | $0.01684 |
| Opus 5.5 | $0.00028 | $0.00674 |
| Sonnet 5.5 | $0.00014 | $0.00337 |
| Haiku 4.5 | $0.00007 | $0.00168 |
Grade A, and why
market-breadth-analyzer 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 8d 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.
Copies of this mod

Market Breadth Analyzer Skill
Purpose
Quantify market breadth health using a data-driven 6-component scoring system (0-100). Uses TraderMonty's publicly available CSV data to measure how broadly the market is participating in a rally or decline.
Score direction: 100 = Maximum health (broad participation), 0 = Critical weakness.
No API key required - uses freely available CSV data from GitHub Pages.
When to Use This Skill
English:
- User asks "Is the market rally broad-based?" or "How healthy is market breadth?"
- User wants to assess market participation rate
- User asks about advance-decline indicators or breadth thrust
- User wants to know if the market is narrowing (fewer stocks participating)
- User asks about equity exposure levels based on breadth conditions
Japanese:
- 「マーケットブレッドスはどうですか？」「市場の参加率は？」
- 「上昇は広がっている？」「一部の銘柄だけの上昇？」
- ブレッドス指標に基づくエクスポージャー判断
- 市場の健康度をデータで確認したい
Prerequisites
- Python 3.9+ with
requestslibrary (for fetching CSV data) - Internet access to reach GitHub Pages URLs
- No API keys required - uses freely available public CSV data
Difference from Breadth Chart Analyst
| Aspect | Market Breadth Analyzer | Breadth Chart Analyst |
|---|---|---|
| Data Source | CSV (automated) | Chart images (manual) |
| API Required | None | None |
| Output | Quantitative 0-100 score | Qualitative chart analysis |
| Components | 6 scored dimensions | Visual pattern recognition |
| Repeatability | Fully reproducible | Analyst-dependent |
Execution Workflow
Phase 1: Execute Python Script
Run the analysis script. If using a nested or date-stamped --output-dir in cron runs, create it first; the history writer expects the directory to already exist.
mkdir -p reports/<routine-or-date>
python3 skills/market-breadth-analyzer/scripts/market_breadth_analyzer.py \
--detail-url "https://tradermonty.github.io/market-breadth-analysis/market_breadth_data.csv" \

--output-dir reports/<routine-or-date>

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.
