Polymarket Equity Markets Trader
ReviewAudited by ClawScan on May 10, 2026.
Overview
This appears to be a disclosed automated Polymarket trading skill, but live mode can place real-money trades and requires a Simmer API key.
Before installing, confirm you trust the source and the simmer-sdk dependency, use a dedicated API key, start in paper-trading mode, and only enable live trading after setting conservative position limits.
Findings (4)
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 agent may create financial exposure and potential losses.
The skill can place real trades when live mode is enabled, which is high-impact but clearly tied to the stated trading purpose and has a paper-trading default.
SAFE BY DEFAULT:\n- No --live flag = paper trading (venue="sim"), zero financial risk.\n- Real trades only with explicit --live flag.
Use paper mode first, enable live mode only with explicit intent, and keep position-size and position-count limits conservative.
Anyone or anything with access to this credential may be able to interact with the connected trading service according to that key's permissions.
The runtime uses a Simmer API key to access the trading client; this credential use is expected for the integration but should be treated as sensitive.
SimmerClient(\n api_key=os.environ["SIMMER_API_KEY"],\n venue=venue,\n )
Use a dedicated, revocable API key with the minimum permissions available, monitor account activity, and remove the key if you stop using the skill.
Installation or execution may require more setup and trust in an external package than the registry summary suggests.
The package metadata summary under-declares the actual dependency and credential requirement shown in clawhub.json. The dependency is purpose-aligned, but users should notice the mismatch.
Required env vars: none; No install spec — this is an instruction-only skill; clawhub.json: "env": ["SIMMER_API_KEY"], "pip": ["simmer-sdk"]
Verify the simmer-sdk package source/version and confirm the SIMMER_API_KEY requirement before running the skill, especially in live mode.
Users may underestimate the risk of live trading if they treat the strategy claims as guaranteed edge.
The skill uses confident financial-performance language that could make users over-trust the strategy, although this is presented as strategy rationale rather than hidden behavior.
Every "will X beat earnings?" market that prices below 50% is almost certainly mispriced unless the company has a specific documented miss history
Treat the strategy text as speculative, validate it independently, and avoid risking funds you cannot afford to lose.
