Description
Trades Polymarket prediction markets focused on Scandinavian and Nordic events — Swedish politics, Norwegian economy, Danish infrastructure, Nordic business...
Usage Guidance
This skill appears to implement the Nordic Polymarket strategy it describes, but there are a few red flags to check before installing:
- Credential review: The skill requires SIMMER_API_KEY (declared in clawhub.json) even though the top-level registry metadata omitted required env vars. Only provide a SIMMER API key you trust and understand (prefer a sandbox/paper account).
- Dependency review: The manifest declares a pip dependency 'simmer-sdk'. Verify the exact pip package (author, project homepage, source code) before installing to avoid pulling a malicious package.
- Test in paper mode first: The code defaults to simulated/paper trading, but live trades are possible with --live. Exercise the skill in sim mode to confirm behavior before enabling live funds.
- Data exfiltration awareness: The skill sends trade requests and 'reasoning' to the Simmer service; any private signals you feed the agent could be transmitted. Don't submit sensitive proprietary alpha through this skill unless you trust the backend.
- Metadata mismatch: Ask the publisher (or maintainer) to reconcile the registry-level metadata (install/required envs) with clawhub.json and SKILL.md so you have a clear picture of what is installed and what environment variables are required.
If you want, I can: (a) list exact lines in the code where external network calls/credentials are used, (b) summarize what would be transmitted to the Simmer API, or (c) suggest a minimal review checklist for the simmer-sdk package.
Capability Analysis
Type: OpenClaw Skill
Name: polymarket-nordic-trader
Version: 0.0.3
The skill is a legitimate trading bot for Polymarket focused on Nordic events. It uses the `simmer-sdk` to execute trades and defaults to a safe paper-trading mode (venue='sim') unless explicitly run with the `--live` flag. The logic in `trader.py` is transparent, implementing conviction-based sizing and timezone-based bias as described in `SKILL.md`. No evidence of data exfiltration, malicious execution, or harmful prompt injection was found.

Capability Assessment
Purpose & Capability
The code and SKILL.md implement a Polymarket-focused Nordic trading strategy and require a Simmer client to discover markets and place trades — that aligns with the described purpose (trading Polymarket Nordic markets).
Instruction Scope
SKILL.md and trader.py stay within trading scope (market discovery, signal computation, trade execution). The skill mentions optional integrations (Riksdagen, SMHI, RSS feeds) which, if wired in, would call external APIs — expected for this domain but worth noting. The agent will send 'reasoning' and trade metadata to the Simmer/Polymarket backend.
Install Mechanism
clawhub.json declares a pip dependency on 'simmer-sdk' (pip install) but the top-level registry summary said 'No install spec' / 'instruction-only' — this metadata mismatch is concerning. Installing a third-party pip package is moderate risk; verify the simmer-sdk package origin and contents before installation.
Credentials
The manifest requires SIMMER_API_KEY (used to authenticate with Simmer). That credential is proportionate to a trading skill, but the registry summary earlier omitted any required env vars — an inconsistency. trader.py also expects SIMMER_API_KEY via os.environ (KeyError if missing). Ensure you understand which account this API key controls and DO NOT provide broad/production credentials without review.
Persistence & Privilege
The skill is not flagged always:true and autostart=false. It won't be force-enabled platform-wide. Note: the skill can execute live trades if launched with the --live flag or invoked by an agent; autonomous invocation is allowed by default on the platform, so be cautious about granting the skill the ability to run without human confirmation.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install polymarket-nordic-trader - After installation, invoke the skill by name or use
/polymarket-nordic-trader - Provide required inputs per the skill's parameter spec and get structured output
Version History
v0.0.3
SDK resilience: try/except runt apply_skill_config
v0.0.2
fix: add _client.live=True so --live actually routes to polymarket-venue for real USDC trades
v1.0.2
Fix apply_skill_config AttributeError for new Simmer SDK compatibility
v1.0.1
Version 1.0.1 – Improved sizing and domain bias logic
- Position sizing now uses conviction-based logic with a built-in "local edge bias" that multiplies conviction depending on CET news timing and event type (e.g., politics, weather, tech, sports).
- Added detailed explanation of conviction sizing formula and local edge bias multipliers—highlighting time-of-day and domain effects.
- Market keywords and tracked categories updated for clarity.
- Tunable parameters for trade sizing and thresholds have been added and clarified.
- Old news feed and API remix suggestions retained, but signal generation and default logic now emphasize intrinsic local edge rather than only keyword/news matching.
v1.0.0
Initial release of Polymarket Nordic & Scandinavian Trader skill:
- Enables automated trading in prediction markets focused on Nordic/Scandinavian events and companies.
- Discovers and monitors markets using local news, data feeds (SMHI, Riksdagen, SCB), and keyword matching.
- Includes risk management parameters: position size, market liquidity, spread, and event timing.
- Defaults to safe paper trading mode; live trading requires explicit flag and credential management.
- Full setup, configuration, and data requirements documented for remixing and deployment.
