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 | $0.00031 | $0.02229 |
| Opus 5 | $0.00015 | $0.01115 |
| Sonnet 5 | $0.00006 | $0.00446 |
| Haiku 4.5 | $0.00003 | $0.00223 |
Grade A, and why
polymarket-signal-sniper 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 6d 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.

The opening of the file, as written. The whole thing — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Polymarket Signal Sniper
Your signals, Simmer's trading intelligence.
🚨 Framework, not a production trading system. Read DISCLAIMER.md before connecting to a wallet with real funds.
This is a template. The default signal source is RSS feeds — remix it with any data source (APIs, webhooks, social media, custom scrapers). The skill handles all the plumbing (market matching, safeguards, trade execution). Your agent provides the alpha.
When to Use This Skill
Use this skill when the user wants to:
- Monitor RSS feeds for trading opportunities
- Trade on breaking news before markets react
- Configure their own signal sources and keywords
- Get Trading Agent-grade safeguards on their trades
Setup Flow
When user asks to install or configure this skill:
-
Install the Simmer SDK
pip install simmer-sdk -
Ask for Simmer API key
- They can get it from simmer.markets/dashboard → SDK tab
- Store in environment as
SIMMER_API_KEY
-
Ask for wallet private key (required for live trading)
- This is the private key for their Polymarket wallet (the wallet that holds USDC)
- Store in environment as
WALLET_PRIVATE_KEY - The SDK uses this to sign orders client-side automatically — no manual signing needed
- Not needed for $SIM paper trading on the Simmer venue
Quick Commands
# Check account balance and positions
python scripts/status.py
# Detailed position list
python scripts/status.py --positions
API Reference:
- Base URL:
https://api.simmer.markets - Auth:
Authorization: Bearer $SIMMER_API_KEY - Portfolio:

GET /api/sdk/positions
Quick Start (Ad-Hoc Usage)
User provides RSS feed and market directly:
User: "Watch this RSS feed for greenland news: https://news.google.com/rss/search?q=greenland"
User: "Snipe any news about trump from this feed"
→ Run with --feed and --market flags:
python signal_sniper.py --feed "https://news.google.com/rss/search?q=greenland" --market "greenland-acquisition" --dry-run
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.
