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 | $0.00054 | $0.02125 |
| Opus 5 | $0.00027 | $0.01063 |
| Sonnet 5 | $0.00011 | $0.00425 |
| Haiku 4.5 | $0.00005 | $0.00213 |
Grade A, and why
drawdown-circuit-breaker 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 13d 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.

Drawdown Circuit Breaker
Overview
Evaluate whether the trader should take new trade risk today based on account-level realized P&L and recent terminal trade outcomes. This skill reads trader-memory-core thesis YAML files only. It produces a circuit_breaker_decision artifact that complements the market-side exposure_decision from exposure-coach.
The circuit breaker is a recommendation and recordkeeping tool. It does not replace human judgment, and it does not enforce broker-side blocks or automated order rejection.
When to Use
- Before screening or sizing any new swing trade candidate
- After a losing trade or partial trim to check whether a cooldown is active
- During daily planning when trader-memory-core contains recent closed or partially closed positions
- As a workflow gate before swing-opportunity-daily proceeds to candidate generation
- When reviewing whether daily, weekly, or monthly loss limits have been breached
Prerequisites
- Python 3.9+
- Local trader-memory-core thesis YAML files, usually under
state/theses/ - Account size in dollars
- No API keys or network access required
Workflow
Step 1: Read Trader Memory State
Point the script at the thesis state directory:
python3 skills/drawdown-circuit-breaker/scripts/check_circuit_breaker.py \
--state-dir state/theses \
--account-size 100000 \
--output-dir reports/
The script scans every th_*.yaml file and reads realized P&L from each thesis status_history[] ledger entry. It does not use _index.json for P&L, because the index is a lightweight lookup file and does not contain the required realized-P&L ledger.
After validating each file, the script groups valid theses by the case-sensitive, whitespace-trimmed thesis_id. If two or more valid files share an ID, it excludes the entire duplicate group from P&L and losing-streak calculations, reports every actual source path, and returns PARTIAL + HALTED until the duplicate state is repaired and the decision is rerun. metrics.theses_scanned counts only accepted theses with unique IDs.
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.

drawdown-circuit-breaker is a skill published in the GitHub repository tradermonty/claude-trading-skills (2,813 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 2,125 once invoked, about $0.0003 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.
