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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00071 | $0.03026 |
| Opus 5 | $0.00036 | $0.01513 |
| Sonnet 5 | $0.00014 | $0.00605 |
| Haiku 4.5 | $0.00007 | $0.00303 |
Grade A, and why
polymarket-fast-loop 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 4d 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 — 275 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Polymarket FastLoop Trader
Trade Polymarket's 5-minute crypto fast markets using real-time price signals. Default: BTC momentum from Binance. Works with ETH and SOL too.
Polymarket only. All trades execute on Polymarket with real USDC. Use
--livefor real trades, dry-run is the default.
This is a template. The default signal (Binance momentum) gets you started — remix it with your own signals, data sources, or strategy. The skill handles all the plumbing (market discovery, import, trade execution). Your agent provides the alpha.
⚠️ Fast markets carry Polymarket's crypto taker fee (
is_paid: true). Effective rate is 3.5% at 50¢, up to ~6.6% on cheap shares (e.g. 5¢ NO). Makers pay 0% and earn a 20% rebate from collected taker fees. Factor this into your edge calculations.
⚠️ Risk monitoring does not apply to sub-15-minute markets. Simmer's stop-loss and take-profit monitors check positions every 15 minutes — which means they will never fire on 5m or 15m markets before resolution. Any risk settings you configure in the Simmer dashboard have no effect on these positions. Size accordingly and do not rely on automated stop-losses for fast market trades.
News-recency veto. Optional guard that checks Simmer's macro-news schedule before order placement and skips matching news-resolution markets inside the first 30 seconds after CPI, BLS jobs/unemployment, FOMC, nonfarm payrolls, or quarterly earnings events. Continuous-feed crypto Up/Down markets are not blocked by this veto. Default is off until internal positive backfill coverage exists; set
enable_news_veto=trueto enable it.
How It Finds Markets
- Queries Polymarket directly (Gamma API) for live fast markets — doesn't depend on Simmer's market inventory
- Discovers new markets as they appear, every cycle
- Works with BTC, ETH, or SOL — just change the asset (
--set asset=ETH) or ask your bot to look for whatever market you want - Runs every 5 minutes to catch each trading window (or every 1 minute for mid-window opportunities)
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
