simmer_trade
Execute or dry-run a single direct trade. Use per-skill tools (simmer_<slug>) for strategy-driven runs.
Safety triple-gate: a live trade requires (1) dry_run=false, (2) venue polymarket or kalshi, AND (3) SIMMER_MCP_ALLOW_LIVE=true env. Missing any gate coerces to sim.
simmer_cancel_order
Cancel a single open order by its order ID. RequiresSIMMER_MCP_ALLOW_LIVE=true.

Onesimmer_<slug> tool per bundled trading skill. Each runs in dry-run paper mode by default. Set trading_venue to sim, polymarket, or kalshi.
