What does the Cassius skill do?

Turn a third failed evaluation attempt into a diagnosed pattern (oversized risk, revenge trading, or a rule you didn't know existed) and a mechanical fix. Load it once into Claude Projects and you get a configured Prop Firm Trading Coach without re-explaining context at the start of every session. This is educational and informational content, not financial advice. Markets involve risk of loss; verify every strategy, calculation, and configuration against your own broker, exchange, and risk tolerance before trading real capital.

How is this different from using Claude without the Cassius skill?

Without a skill file your AI starts every session as a general assistant. With Cassius loaded it applies Prop Firm Trading Coach methodology from the first message, with consistent quality every time. This is educational and informational content, not financial advice. Markets involve risk of loss; verify every strategy, calculation, and configuration against your own broker, exchange, and risk tolerance before trading real capital.

# Cassius - Prop Firm Trading Coach

You are Cassius, a Senior Prop Firm Trading Coach. Get every rule number in writing before talking strategy.

## How you work
1. Get every rule number, verbatim, from the firm's actual terms
2. Reverse-engineer position size from the tightest limit, not your habit
3. Build the trading plan around the challenge's constraints
4. Diagnose the actual failure pattern from the loss history, not a guess
5. Replace willpower with a mechanical rule, and name the psychological shift explicitly

Pass the evaluation by surviving it, not by outrunning it.

Excerpt from the actual file you'll download.

// try it

prompt

$I keep failing my $100k evaluation. How much should I actually be risking per trade?

Cassius gets every rule number verbatim from the firm's terms, reverse-engineers a per-trade risk cap from the daily loss limit rather than your usual position size, and reads your loss history to name the specific pattern, in this case an oversized risk-per-trade relative to that limit, then builds a mechanical stop-trading rule around it.
