signal-to-trade-demo

signal-to-trade-demo is a skill for Codex from BlockRunAI/blockrun-mcp. It costs 88 tokens per session (1,688 once invoked), scanned A, original, MIT.

A guided demo workflow for turning current prediction-market data into a possible trade preview. It uses Polymarket, a site where people trade contracts on whether events will happen, and keeps the demo in dry-run mode unless the user explicitly approves a real order.

In plain words
What is it for?
Use it to demonstrate a complete discover, verify, analyze, preview, and inspect workflow. It helps prepare a balanced signal and a simulated order for a current Polymarket market.
Why use it?
It removes the need to manually gather market prices, past probabilities, trading activity, and available liquidity for a live demonstration. It also helps prevent exposing account details or submitting an unintended trade.

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

signal-to-trade-demo 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 13d 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.

How it starts

The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Signal-to-Trade Demo

Run one reproducible chain: discover → verify → analyze → preview → inspect. Treat signals as evidence, never as a promise of profit. Never expose a wallet, credential, order ID, or transaction hash in presentation output.

Read references/demo-cases.md when selecting a case or preparing a fallback.

Hard safety contract

  1. In a presentation dry-run, do not call wallet, setup, positions, orders, or resources. Those responses can contain wallet-derived identifiers before the final answer is redacted. The presenter performs account readiness privately before screen sharing.
  2. If the current egress is blocked, never call a funds-affecting action with confirm:true. Continue with live data and a dry-run order preview only. A Stanford/US presentation is always dry-run mode.
  3. Always preview through blockrun_polymarket_read action:"preview". It has no confirmation input and cannot sign or submit an order. A real order requires the user's explicit approval of the exact market, outcome, amount, price/type, and current region eligibility.
  4. Choose the smallest whole-dollar preview from $1–$5 that satisfies the live min_order_size and book depth. Never present a smaller, non-executable preview as valid. Do not split orders to bypass caps.
  5. Paid market-data calls may run in parallel on Base. On Solana keep @blockrun/llm >= 3.8.4, which is what makes concurrent payments distinct.

1. Private operator preflight

  • Confirm the Trading profile exposes nine tools and no image/video/media tool: wallet, price, dex, markets, surf, defi, rpc, polymarket_read, polymarket.
  • Before screen sharing, the human operator may check blockrun_wallet, run setup, and inspect positions/orders. Never include those raw calls in the presentation conversation.
  • For the live dry-run conversation, begin directly with public market discovery. No account state is required to preview a CLOB order.

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.
