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

portfolio-rebalance scanned grade A with 1 finding 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 9d 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.

Portfolio Rebalance — Solo Trader

Compare current IB portfolio allocation to target weights. Show drift. Suggest trades.

Prerequisites

The user must have target allocations defined. If not, ask them to provide targets as a simple table:

Asset class / ticker : target %

If they say "I don't have targets" — help them define simple ones based on what they currently hold. Don't impose a model. This is their portfolio.

Workflow

Step 0: Session check

curl -sk https://localhost:5000/v1/api/tickle

Step 1: Get account and NLV

curl -sk https://localhost:5000/v1/api/portfolio/accounts
curl -sk "https://localhost:5000/v1/api/portfolio/$ACCT/summary"

Extract Net Liquidation Value (NLV) from summary. This is the denominator for all % calculations.

Step 2: Pull all positions

curl -sk "https://localhost:5000/v1/api/portfolio/$ACCT/positions/0"

For each position: ticker, assetClass, mktValue, position, unrealizedPnl.

Step 3: Classify holdings

Group positions by the user's target categories. Common groupings:

  • By asset class: stocks, bonds, cash, options, futures
  • By sector: tech, financials, energy, etc.
  • By ticker (if targets are per-position)
  • By geography: US, international, EM

Use the grouping that matches the user's targets. If targets are per-ticker, use per-ticker. If targets are by asset class, aggregate.

Step 4: Calculate drift

For each category:

current_pct = category_mkt_value / nlv * 100
drift = current_pct - target_pct
dollar_drift = drift / 100 * nlv

ALL arithmetic via python3 -c. No mental math.

Step 5: Cash and buying power

curl -sk "https://localhost:5000/v1/api/portfolio/$ACCT/ledger"

Check cash balance. If rebalancing requires buying, verify cash is available. If not, rebalancing means selling overweight to fund underweight.

Step 6: Generate trade suggestions

For each category outside the rebalancing band (default: +/- 3% drift):

  • Overweight: suggest selling $X to bring to target
  • Underweight: suggest buying $X to bring to target

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.
