Usage Guidance
This skill appears to be a real Polymarket trading bot that reasonably needs an API key and a client library, but the package metadata is inconsistent and there is executable code, so proceed with caution. Before installing or providing any credentials: 1) Confirm which env var(s) the runtime actually requires (SIMMER_API_KEY) and ensure you control the API key's permissions (paper-trade vs live-trade scopes). 2) Verify the simmer-sdk package source and inspect trader.py fully to ensure there are no hidden network endpoints, telemetry, or code paths that place live trades without an explicit --live flag. 3) Keep autostart disabled until you are satisfied with behavior; test in a sandbox with a restricted API key that can only paper-trade. 4) Ask the publisher to correct the registry metadata (declare the required env vars and the pip dependency or provide an explicit install spec) — metadata inconsistencies are a red flag. If you are not comfortable auditing the code or supplying an API key, do not install.
Capability Analysis
Type: OpenClaw Skill
Name: polymarket-coffee-trader
Version: 0.0.3
The skill is a legitimate trading bot designed to execute trades on Polymarket coffee markets based on seasonal meteorological patterns. The code in trader.py is well-structured, transparently implements the described strategy, and follows a 'safe by default' approach by requiring an explicit --live flag for real financial transactions. No indicators of data exfiltration, malicious execution, or prompt injection were found.

Capability Assessment
Purpose & Capability
The declared purpose (automated trading on Polymarket) legitimately requires an API credential and a client library; clawhub.json lists a required env var SIMMER_API_KEY and a pip dependency simmer-sdk which match that need. However the skill header/registry metadata states "Required env vars: none" and the overall install section claims "No install spec — instruction-only skill." Those three pieces (registry metadata, presence of clawhub.json, and code) are inconsistent and reduce trust.
Instruction Scope
SKILL.md and the visible portion of trader.py stay on-topic: they describe market discovery, conviction sizing, and a clear paper-vs-live trade model (paper by default; explicit --live required to place real trades). The instructions reference only trade-related environment variables (e.g., SIMMER_ENSO_PHASE) and date-derived signals; there are no obvious instructions to read unrelated system files or exfiltrate arbitrary data.
Install Mechanism
The package is marked as "No install spec" but clawhub.json declares a pip dependency (simmer-sdk). That implies an install step will be needed even though the top-level metadata says none. Using pip to install simmer-sdk is reasonable for a trading skill, but the lack of an explicit install spec is an inconsistency that could hide additional install actions. No direct download-from-URL or archive-extraction signs are present.
Credentials
The only secret-like requirement in clawhub.json is SIMMER_API_KEY, which is proportionate for a trading client that needs to authenticate to a trading service. The code also reads many SIMMER_* tunables (MAX_POSITION, MIN_TRADE, ENDO_PHASE, etc.) which are configuration values rather than unrelated credentials. The mismatch is that the skill registry metadata claims no required env vars while the manifest requires SIMMER_API_KEY; this should be clarified before installing.
Persistence & Privilege
No elevated persistence flags were requested: always is false, autostart is false, and disable-model-invocation is false (normal). clawhub.json declares an automaton entrypoint (trader.py) but autostart=false means it won't run automatically unless explicitly enabled—this is appropriate for a trading skill.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install polymarket-coffee-trader - After installation, invoke the skill by name or use
/polymarket-coffee-trader - Provide required inputs per the skill's parameter spec and get structured output
