Usage Guidance
This skill appears to do what it says: a Polymarket trading bot that uses the simmer-sdk and public Binance klines. Before installing: 1) Expect to provide SIMMER_API_KEY (sensitive) — create a key with the minimum scope necessary and be aware it can place real trades if you run with --live or enable the cron. 2) Run extensively in paper/dry mode and keep bet_size very small initially. 3) Review and, if desired, pin the simmer-sdk package version before installing to avoid supply-chain surprises. 4) Note the registry metadata in the listing is inconsistent (it omitted the required env var); verify clawhub.json / SKILL.md over the registry summary. 5) If you use the optional Discord webhook, remember it can disclose trade signals; only set it to a webhook you control. If you want higher assurance, ask the author for an auditable release (signed package or specific pinned dependency versions) and a complete explanation of API key scopes the skill expects.
Capability Analysis
Type: OpenClaw Skill
Name: polymarket-btc-midcandle
Version: 1.1.1
The skill is a functional trading bot designed to execute momentum-based trades on Polymarket BTC markets via the Simmer SDK. It fetches market data from Binance (api.binance.com) and manages trades through the Simmer API, with optional Discord notifications. While the code contains minor bugs (e.g., references to undefined functions like 'record_trade_outcome' and missing config keys like 'max_consecutive_losses' in btc_midcandle.py), there is no evidence of malicious intent, data exfiltration, or unauthorized system access.
Capability Assessment
Purpose & Capability
The code and SKILL.md implement a Polymarket / Simmer trading bot (finding markets, computing momentum from Binance klines, and executing trades via simmer-sdk). Requiring SIMMER_API_KEY and simmer-sdk is proportional to that purpose. However, the registry-level 'Requirements' section in the provided summary claimed 'Required env vars: none' which is incorrect — the skill requires SIMMER_API_KEY and several SIMMER_BTCMC_* env tunables (also reflected in clawhub.json).
Instruction Scope
The runtime instructions (set SIMMER_API_KEY, set agent ID, run python btc_midcandle.py in paper mode, then --live to trade, and optionally set a cron) align with the stated trading purpose. The script fetches public Binance klines and calls the Simmer API to discover markets and execute trades; optional Discord webhook alerts are configurable. There are no instructions to read unrelated system files or exfiltrate arbitrary data.
Install Mechanism
There is no formal install spec in registry metadata, but clawhub.json and the script recommend/require the simmer-sdk Python package (pip). The skill does not download code from arbitrary URLs or run installers from untrusted hosts. This is moderate risk (third‑party package install) but expected for a Python SDK dependency.
Credentials
Environment access requested (SIMMER_API_KEY, SIMMER_BTCMC_* tunables) is proportionate to a trading bot. The SIMMER_API_KEY gives permission to act on your Simmer/Polymarket account, so it is sensitive but expected. Minor issues: the registry summary initially listed no required env vars (incoherent) and the code references optional TRADING_VENUE and other tunables; review what API key scopes are granted before use.
Persistence & Privilege
always:false and autostart:false. The clawhub.json contains a cron schedule (recommended by SKILL.md) and an entrypoint; running the cron or invoking --live will execute trades. The skill can be invoked autonomously by an agent (platform default), which is normal for skills, but this means the API key can be used to trade whenever the skill runs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install polymarket-btc-midcandle - After installation, invoke the skill by name or use
