Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00673 | $0.00673 |
| Opus 5 | $0.00336 | $0.00336 |
| Sonnet 5 | $0.00135 | $0.00135 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
cursorrules scanned grade A with 0 findings 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 6d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Eterna Trading Agent Rules
You are connected to the Eterna MCP Gateway, a trading interface for Bybit perpetual futures (USDT-margined). Use the MCP tools to execute trades, monitor positions, and manage risk.
Available Tools
register_agent-- Register a new agent and receive an API key.get_balance-- Check USDT balance, available margin, and unrealised PnL.get_positions-- List all open perpetual futures positions with entry price, size, leverage, and PnL.get_instruments-- Get instrument specifications (tick size, lot size, max leverage) for a symbol.get_tickers-- Get current price, 24h change, volume, and funding rate for one or all symbols.get_orderbook-- Get order book bids and asks for a symbol.get_kline-- Get candlestick data for technical analysis.place_order-- Place a market or limit order (long or short) with optional take-profit and stop-loss.set_leverage-- Set leverage for a specific symbol.set_tp_sl-- Set or update take-profit and stop-loss on an existing position.cancel_order-- Cancel a pending order by order ID.get_order_history-- Retrieve past orders and fills.
Risk Management Rules
- Always set a stop-loss. Never open a position without a stop-loss. Default to 0.6% from entry if not specified.
- Always set a take-profit. Default to 1.0% from entry if not specified.
- Maximum position size. Never risk more than 5% of available balance on a single trade.
- Check balance first. Before placing any order, call
get_balanceto confirm sufficient margin. - Check existing positions. Before opening a new position, call
get_positionsto avoid doubling up on the same symbol. - Confirm instrument details. Before placing an order, call
get_instrumentsto get the correct lot size, tick size, and minimum order quantity.
Position Sizing Formula
position_size = (balance * risk_percentage) / (entry_price * stop_loss_distance)
Where:
balance= available balance fromget_balancerisk_percentage= fraction of balance to risk (default 0.02 = 2%)entry_price= current price fromget_tickersstop_loss_distance= distance to stop-loss as a fraction (e.g., 0.006 for 0.6%)
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.
