Description
Cross-market prediction market data aggregator. Covers Polymarket, Manifold, Metaculus, and Kalshi. Finds arbitrage between markets, tracks consensus drift,...
Usage Guidance
This skill's description says it will call multiple external APIs (Polymarket, Manifold, Kalshi) and even perform EIP-712 signing, but the registry lists no required API keys or dependencies — that's inconsistent. Before installing or using it, ask the publisher for: (1) the full source or manifest so you can audit network calls; (2) an explicit list of required environment variables and whether any private keys or signing capabilities are needed (never provide private wallet keys); (3) how credentials are stored and used (prefer read-only API keys scoped with minimal permissions); (4) whether it will invoke other skills (e.g., argus-edge) and whether those are available/trusted. If they cannot supply clear, verifiable answers or a public repo, treat the skill cautiously and run it only in a restricted/sandboxed environment or not at all.
Capability Analysis
Type: OpenClaw Skill
Name: prediction-market-aggregator
Version: 1.0.0
The provided files, `_meta.json` and `SKILL.md`, describe a prediction market aggregation skill. The `_meta.json` contains standard metadata. The `SKILL.md` details the skill's features, markets covered, and usage instructions, including the need for API keys for certain platforms. There are no instructions for prompt injection against the AI agent, no commands for unauthorized execution, data exfiltration, or persistence. The skill's purpose, while involving financial markets and potential 'bets', is clearly stated and does not exhibit malicious intent within the scope of the provided documentation.
Capability Assessment
Purpose & Capability
The SKILL.md describes direct integration with Polymarket (including EIP-712 signing), Manifold, Kalshi (API keys), and an Argus 'argus-edge' skill. However the registry metadata lists no required env vars, no primary credential, and no declared dependency on other skills. Real use of Polymarket/Kalshi/Manifold typically requires API keys and (for Polymarket trading) signing keys; those are not declared, which is inconsistent with the stated purpose.
Instruction Scope
The instructions tell the agent to query multiple external APIs and to 'plug into' an Argus edge-detection skill but give no concrete auth/endpoint guidance or handling for credentials. The SKILL.md implicitly expects network calls and cross-skill invocation, but does not specify how credentials are obtained, stored, or protected.
Install Mechanism
This is an instruction-only skill with no install spec and no code files. That reduces supply-chain risk from arbitrary downloads, but also means there is no source code to review—making it harder to verify behavior.
Credentials
The skill claims it will use APIs that usually require API keys and EIP-712 signing (which could imply wallet private keys), yet requires.env is empty. Requesting private keys or signing ability would be high-risk; the absence of declared env vars is a mismatch and a red flag.
Persistence & Privilege
always:false (normal) and disable-model-invocation:false (normal autonomous capability). The skill references invoking another skill ('argus-edge') but does not request elevated or persistent system-level privileges or to modify other skills' configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install prediction-market-aggregator - After installation, invoke the skill by name or use
/prediction-market-aggregator - Provide required inputs per the skill's parameter spec and get structured output
