Polymarket Edge Liquidity

Trades active Polymarket-imported markets on Simmer when estimated edge and liquidity filters pass.

Security Scan

The skill's code, instructions, and requested environment variable (SIMMER_API_KEY) align with its stated purpose of scanning and trading markets on Simmer; nothing in the package appears disproportionate or unrelated to that function.

Purpose & Capability

Name/description, required env var (SIMMER_API_KEY), and the code all point to interacting with the Simmer trading API. The optional TRADING_VENUE, scan/trade parameters, and use of a simmer-sdk client are consistent with a trading strategy skill.

Instruction Scope

SKILL.md and edge_liquidity.py limit actions to fetching markets, filtering by liquidity/edge, optionally calling client.trade when run with --live, and printing results. The instructions do not access unrelated files, credentials, or external endpoints beyond the Simmer client.

Install Mechanism

This is an instruction-only skill with no install spec in the registry bundle, but SKILL.md declares a pip dependency on 'simmer-sdk'. The platform would need to install that package; verify that the simmer-sdk package is the official/library you expect before installation.

Credentials

Only SIMMER_API_KEY is required (plus optional TRADING_VENUE and tuning env vars). That single credential is proportionate to performing trades on Simmer; there are no unrelated secret/env requests.

Persistence & Privilege

always:false (no forced inclusion). SKILL.md includes a cron entry (*/20) and automaton.managed:true which indicates it may be scheduled to run periodically by the platform. The code executes real trades only when invoked with --live; ensure scheduled runs won't pass live mode unless intended. Autonomous invocation with a live API key would allow the skill to place trades, which is expected for a trading skill but should be authorized deliberately.

Assessment

This skill appears coherent for automated trading on Simmer. Before installing, verify the source/trustworthiness of the simmer-sdk package the platform will install. Use a SIMMER_API_KEY with limited permissions/funds for testing and run a dry run first (default mode) — the script only executes real trades when run with --live. Also confirm the platform's scheduler or automaton won't invoke the script in live mode automatically. If you need higher assurance, review or fingerprint the simmer-sdk package and/or run the script in an isolated environment first.

Simple strategy skill based on your starter settings:

• Scan every 20 minutes
• Require minimum edge (MIN_EDGE, default 0.03)
• Require minimum liquidity (MIN_LIQUIDITY, default 3000)
• Default to dry-run unless --live is provided

Environment

• SIMMER_API_KEY (required)
• TRADING_VENUE (optional, default: simmer)
• SCAN_LIMIT (optional, default: 25)
• MIN_EDGE (optional, default: 0.03)
• MIN_LIQUIDITY (optional, default: 3000)
• TRADE_AMOUNT (optional, default: 10)

Run manually

python3 edge_liquidity.py
python3 edge_liquidity.py --live

Notes

• Trades are tagged with source=sdk:polymarket-edge-liquidity and skill_slug=polymarket-edge-liquidity
• Reasoning is always included for each trade
• By default this runs on virtual $SIM via TRADING_VENUE=simmer
