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 | $0.00076 | $0.01876 |
| Opus 5 | $0.00038 | $0.00938 |
| Sonnet 5 | $0.00015 | $0.00375 |
| Haiku 4.5 | $0.00008 | $0.00188 |
Grade A, and why
polymarket-nothing-ever-happens 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 12d 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.

Polymarket Nothing-Ever-Happens Trader
Buy NO on standalone yes/no Polymarket markets priced below a configurable cap.
🚨 Framework, not a production trading system. Read DISCLAIMER.md before connecting to a wallet with real funds.
This is a template. The default logic buys NO on any non-sports standalone market where NO costs ≤5¢. Remix it with custom filters (minimum volume thresholds, specific categories, date ranges) or pair it with a signal to skip markets where YES might actually happen. The skill handles plumbing (discovery, import, fee checks, execution). You define which markets to trade.
Based on: sterlingcrispin/nothing-ever-happens
The Thesis
On most standalone binary prediction markets, the event resolves NO — nothing dramatic happens. Markets systematically overprice dramatic YES outcomes. When NO is trading at 3¢–5¢, you're getting 20–33x payout if you're right, and the base rate of "nothing happens" is often much higher than the implied 3–5%.
⚠️ Automated stop-losses cannot protect against gap-resolution. Many NO-fade targets, weather temperature buckets especially, do not decay toward their losing outcome. They gap: the price sits near your entry, then jumps straight to about 0 at resolution. A percentage stop has no intermediate price to trigger on and no liquidity to exit into once it is near zero, so it cannot cap your downside on these markets. Size every position for the full loss, not for the stop. See DISCLAIMER.md.
What It Does
- Scans Polymarket events via Gamma API for standalone yes/no markets
- Filters out sports, grouped events, low-liquidity markets
- Selects markets where NO ask ≤ price cap (default 5¢)
- Imports each candidate into Simmer
- Checks fees (only trades zero-fee markets) and safeguards
- Buys NO via Simmer SDK, sized by

What ships with it
4 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.

polymarket-nothing-ever-happens is a skill published in the GitHub repository SpartanLabsXyz/simmer-sdk (48 stars, last pushed today), licensed MIT. It adds 76 tokens to every session and 1,876 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
