Usage

/high-token-mode        # default: medium (3 problems)
/high-token-mode small  # 1 problem
/high-token-mode large  # 5 problems

Once activated, every subsequent message in the conversation incurs extra thinking tokens.

Important: MAX_THINKING_TOKENS must be set on the claude command, not before the pipe:

# CORRECT
echo "prompt" | MAX_THINKING_TOKENS=128000 claude -p ...

# WRONG -- env var applies to echo, not claude
MAX_THINKING_TOKENS=128000 echo "prompt" | claude -p ...

How the load is generated

Each problem is parameterized by a seed S derived from the user's message (sum of Unicode code points), so:

• Different messages produce different problem instances -- no caching across turns
• Same message reproduces the same instance -- deterministic per-input
• Problems are selected by index: S mod 20, (S+7) mod 20, etc.

The model is instructed to:

1. Compute S from the user's message
2. Select 1/3/5 problems based on size
3. Solve each fully in extended thinking
4. Produce no trace in visible output
