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 | $0.00062 | $0.02019 |
| Opus 5 | $0.00031 | $0.01009 |
| Sonnet 5 | $0.00012 | $0.00404 |
| Haiku 4.5 | $0.00006 | $0.00202 |
Grade A, and why
polymarket-worldcup-copytrader 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.
How it starts
The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
World Cup Copytrader
Copy the top World Cup traders on Polymarket using Simmer's auto-curated leader set. No wallet list to configure — Simmer's daily curation job screens the top WC traders for copyability (slippage-adjusted copy P&L via PolyNode) and serves the qualified set.
🚨 Read DISCLAIMER.md before going live. This skill executes trades automatically. Dry-run is the default; pass
--liveto execute.
Sim-first. The default venue is
$SIM(Simmer's LMSR). Validate the skill works correctly on sim before switching to--venue polymarketwith real USDC.
Copyability screening reduces slippage risk; it does not remove market risk.
What it does
- Fetches the daily-curated WC leader set from Simmer (
GET /api/sdk/wc/copy-leaders). - Runs the leaders' wallets through Simmer's copytrading engine to compute a portfolio-level rebalance: size-weighted aggregation across all leaders, conflict detection, Top-N filtering, drift/stale checks.
- Executes the rebalance trades via your Simmer wallet (managed or self-custody).
The curation pipeline runs once daily at 02:00 UTC: PolyNode top-traders → PolyNode
slippage-adjusted copy-PnL screen (exclude_toxic=true) → top-10 copyable WC sharps.
You follow this set, not wallets you chose yourself.
How it differs from polymarket-copytrading
| polymarket-copytrading | polymarket-worldcup-copytrader | |
|---|---|---|
| Wallet list | User configures manually | Auto-curated from server |
| Scope | All Polymarket markets | World Cup markets only |
| Curation | None (follows whoever you set) | PolyNode copy-PnL screen |
| Modes | Polling + Reactor | Regular (daily rebalance) |
| Tier | Free | Free |
Setup
-
Install the Simmer SDK (0.17.27 or newer):
pip install -U 'simmer-sdk>=0.17.27' -
Set your Simmer API key:
export SIMMER_API_KEY=... # simmer.markets/dashboard → SDK tabIf your agent already registered via the
simmerskill,SIMMER_API_KEYis set from the registration response — the dashboard is only for recovering it.
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.
