Polymarket FastLoop Trader
ReviewAudited by ClawScan on May 18, 2026.
Overview
This skill is openly an automated trading bot, but it can run unattended live trades on a schedule using trading credentials, so it should be reviewed carefully before enabling.
Use this only if you understand that live mode can place real-money trades. Test in paper mode first, use a dedicated wallet with limited funds, keep conservative budget limits, verify the simmer-sdk dependency, and do not enable cron/live mode unless you want unattended trading.

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.
If live mode is enabled, the skill may spend funds and create Polymarket positions automatically.
The documentation explicitly supports real-money trading and a quiet cron workflow. It discloses the behavior and includes budget settings, but does not describe a per-trade approval step for live scheduled operation.
Default is paper mode. Use `--live` for real trades... python polymarket-simmer-fastloop.py --live --quiet
Start in paper mode, keep low max_position and daily_budget limits, and only enable --live or cron after reviewing the strategy and accepting unattended trading risk.
The skill can keep running on a schedule and may continue trading until the schedule or credentials are removed.
The manifest requests managed scheduled execution every five minutes. This is disclosed and aligned with fast-market trading, but it can continue acting after setup without further user interaction.
"cron": "*/5 * * * *", "automaton": { "managed": true, "entrypoint": "polymarket-simmer-fastloop.py" }Confirm whether you want persistent automation, monitor early runs, and disable the managed cron job when you no longer want the bot active.
Anyone or anything with access to the live wallet key may be able to authorize trades from that wallet.
The skill needs trading credentials for its stated purpose, and the wallet key is documented for live Polymarket trading. A private wallet key is highly sensitive, and it is not listed in the registry env declarations.
`SIMMER_API_KEY` ... `WALLET_PRIVATE_KEY` | Optional | Your Polymarket wallet key | Required only if `TRADING_VENUE="polymarket"`
Use a dedicated low-balance trading wallet, avoid setting WALLET_PRIVATE_KEY for paper mode, and revoke or rotate credentials if you stop using the skill.
Future or unexpected versions of the dependency could affect how trading credentials and orders are handled.
The skill relies on an external SDK package without a pinned version. That dependency is central to trading execution, so package provenance matters even though the dependency is purpose-aligned.
"pip": [ "simmer-sdk" ]
Verify the simmer-sdk package source and consider pinning a reviewed version before using live trading.
