Usage Guidance
Before installing, note these points:
- The code requires a SIMMER_API_KEY and depends on the 'simmer-sdk' Python package even though the skill description/README states 'no external API required'. That description appears to refer only to the bias logic, not the trading plumbing — but the mismatch is confusing and should be clarified.
- If you provide an API key, verify what 'Simmer' is and what permissions the API key grants. Use a key with the minimum privileges needed (paper/sim-only key if available) and avoid re-using high-privilege keys from other services.
- Inspect or vet the 'simmer-sdk' package (source, maintainers, PyPI page) before installing; dependency packages are a common supply-chain risk.
- Run the skill in paper/sim mode first and confirm network endpoints and behaviour. Only enable --live after you confirm the endpoint, the account used, and the intended risk parameters.
- Ask the skill author to correct the registry/README so the required env var and pip dependency are explicit and to document the exact API endpoint and recommended key scopes. If you need help checking simmer-sdk or the Simmer vendor, request that information before granting credentials.
Capability Analysis
Type: OpenClaw Skill
Name: polymarket-crypto-onchain-trader
Version: 0.0.3
The skill is a legitimate crypto trading bot for Polymarket that uses the 'simmer-sdk' to execute trades based on market sentiment and on-chain timing signals. The code in trader.py implements the strategy described in SKILL.md, featuring a 'safe by default' paper-trading mode and risk management tunables. No indicators of data exfiltration, malicious execution, or prompt injection were found; the logic is transparent and aligned with its stated purpose.
Capability Tags
Capability Assessment
Purpose & Capability
The skill is a Polymarket trader so requiring a trading client/API key is reasonable. However, SKILL.md (and the short description) repeatedly state that the on-chain bias uses 'no external API' and that the skill is 'no external API required' — yet clawhub.json and trader.py declare and use a SIMMER_API_KEY and a pip dependency on 'simmer-sdk'. The registry summary omitted the required env var, creating an incoherence between what the skill claims and what it actually needs.
Instruction Scope
The SKILL.md instructions focus on market discovery, conviction sizing, and execution. They do not instruct the agent to read unrelated system files or transmit arbitrary environment data. The skill defaults to paper trading and requires an explicit --live flag for real trades, which is a sensible safety mode.
Install Mechanism
There is no separate install spec in the registry UI, but clawhub.json declares a pip dependency ('simmer-sdk'). A PyPI dependency is a normal mechanism for a trading client, but it is a moderate-risk install source compared with no install. The registry metadata and SKILL.md should explicitly document the dependency and where 'simmer-sdk' comes from (official package name, maintainer).
Credentials
trader.py directly reads os.environ['SIMMER_API_KEY'] and several SIMMER_* tunables. clawhub.json also lists SIMMER_API_KEY in requires.env, but the top-level registry summary omitted required env vars — this mismatch is problematic. Requiring a Simmer API key is proportionate for trade execution, but the code requires it even for paper mode (KeyError will occur if it's missing), so the manifest/README should clearly state that an API key is mandatory and document the key's scope/permissions.
Persistence & Privilege
always:false and autostart:false. The skill provides an automaton entrypoint but does not request forced always-on presence. It does not attempt to modify other skills or system-wide configuration. Autonomous invocation is permitted (disable-model-invocation:false) which is normal for skills; this is not combined with other high-risk flags.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install polymarket-crypto-onchain-trader - After installation, invoke the skill by name or use
/polymarket-crypto-onchain-trader - Provide required inputs per the skill's parameter spec and get structured output
