polymarket-nothing-ever-happens

polymarket-nothing-ever-happens is a skill for Claude Code, Codex from SpartanLabsXyz/simmer-sdk. It costs 50 tokens per session (2,787 once invoked), scanned A, original, MIT.

A trading skill for Polymarket, a website where people buy shares based on whether real-world events will happen. It finds certain non-sports yes/no markets and can buy “NO” shares below a chosen price.

In plain words
What is it for?
Use it to search standalone non-sports markets, filter candidates by price and other rules, and execute selected NO trades through the Gamma API and wallet setup.
Why use it?
It removes the manual work of scanning markets, checking fees, and placing trades. It is a trading framework, not a production system, so real-money risks still need review.

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

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 14d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (nothing_ever_happens.py, tests/test_paper_mode_venue.py, tests/test_replay_plane.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What's New in v1.1.3

  • Club/league sports tokens (SIM-5518). Replay text now drops Celta/Bayern-class matchups and league-only titles (bundesliga, premier league, …). Political X vs Y stays eligible. Live is still tag/category.
  • Replay already-holding stays at max_bet. get_positions() omits the venue filter under replay (replay 422s on venue, same class as weather SIM-5484). A held market_id is not re-bought on later ticks.
  • price_cap docs match code. Default is 0.10. CONFIG_SCHEMA is the source of truth.

What's New in v1.1.2

  • Standalone is tape-authoritative (CTO pass 2). The replay listing is requested at limit=1000 (the whole tape slice), so sibling counting covers every market on the tape, and rows with no event_id are dropped rather than admitted. The remaining FIX caveat is only that the tape itself may omit a sibling Polymarket had.

What's New in v1.1.1

  • CTO review P1. Live ensure_can_trade with a missing or non-numeric max_safe_size now refuses to trade (no uncapped MAX_BET_USD). Replay listings expose event_id; the skill drops events that have more than one row on the page (standalone = live Gamma len(markets)==1).
  • FIX caveat. If the tape omits event_id, or the listing page only shows one grouped leg, that row still enters. Tape volume stands in for both liquidity and 24h volume.

What's New in v1.1.0

  • Replay plane (SIM-5443). Under simmer backtest (SIMMER_REPLAY=1) discovery, import, and the clock come from the existing replay harness — same SIMMER_REPLAY / SIMMER_REPLAY_NOW pattern as BTC up-down and weather. Live Gamma stays dark. Import accepts replay status=active. Sports still drop when tape tags are empty (question/slug tokens). Daily-spend uses the frozen tick, not wall clock.

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.
