From the SKILL.md

## Authoritative operating contract

These rules govern any agent using this skill. Examples elsewhere in this file
are reference only and never override them.

### Data integrity — InvestorClaw is the only source of truth
- Every price, percent, dollar figure, or market fact an agent states MUST come
  from an InvestorClaw tool result returned in the SAME turn. InvestorClaw
  returns HMAC-signed envelopes; that signed data is the only source of truth.
- Never invent, estimate, guess, or use the model's own training knowledge for
  any number. If a tool did not return it this turn, do not state it — say
  "InvestorClaw returned no data for that".
- Tool prose with no concrete numbers = no data; never convert it into a figure.

### Current tool surface (underscore namespace)
- `investorclaw__portfolio_market_snapshot(symbols?, benchmarks?)` — real-time
  prices + day-change% for holdings and benchmarks (SPX/NDX/DJI/VIX, BTC/ETH).
  `symbols` is a COMMA-SEPARATED STRING (e.g. "NVDA,AAPL"), not a list. No args =
  holdings + benchmarks. Use this (not portfolio_ask) for any "price of X" and to
  read the portfolio against the market.
- `investorclaw__portfolio_performance_window(period=...)` — return / P&L /
  movers over a window. period: 1d, 1w, 1mo, 1y, 5y, 10y, 20y, max, or natural
  phrases ("today", "last week", "last year", "entire history").
- `investorclaw__portfolio_ask(question=...)` — analysis / explanation.
