Usage Guidance
This skill appears to be a straightforward read-only Polymarket query helper; trading features are optional but require a wallet private key. Before installing or using: (1) do not paste your real wallet private key into environment variables or .env unless you understand the risk; prefer a dedicated, low-value wallet for automation/testing; (2) if you want read-only use, do not set POLYMARKET_PRIVATE_KEY anywhere accessible to the agent; (3) if you must enable trading, confirm the platform will prompt/require explicit consent before executing trades or disable autonomous invocation for this skill; (4) verify the external endpoints (gamma-api.polymarket.com, clob.polymarket.com) are expected and that you trust them; (5) the skill's source/homepage are not listed — if provenance matters, ask the publisher for a source repo or homepage before trusting it with sensitive credentials.
Capability Analysis
Type: OpenClaw Skill
Name: sports-skills-polymarket
Version: 1.0.0
The skill bundle provides integration with Polymarket sports prediction markets, including high-risk trading capabilities (e.g., 'create_order', 'cancel_all_orders') that require the use of a 'POLYMARKET_PRIVATE_KEY' environment variable. While the instructions in SKILL.md and references/commands.md are detailed and appear aligned with the stated purpose, the handling of sensitive private keys and the ability to perform financial transactions constitute significant risky capabilities. No evidence of intentional data exfiltration or malicious logic was found in the provided files, including the scripts/validate_params.sh helper script.

Capability Assessment
Purpose & Capability
The name/description (Polymarket sports prediction markets) matches the SKILL.md, API references, and commands. The skill is primarily read-only and documents which endpoints (Gamma / CLOB) to call; trading functionality is optional and clearly marked as requiring a Python SDK and a wallet private key.
Instruction Scope
SKILL.md instructs only API queries, CLI usage, and parameter validation. It does not ask the agent to read unrelated system files or contact unexpected third-party endpoints. It does, however, instruct users to configure a wallet and suggests setting POLYMARKET_PRIVATE_KEY in environment/.env for trading — this is out-of-band sensitive data referenced in the runtime instructions (but limited to trading operations).
Install Mechanism
There is no install spec and no network download of code; the skill is instruction-only with one small shell helper script. Trading requires an optional pip install (sports-skills[polymarket]) which is reasonable and documented.
Credentials
The repo does not declare required env vars, yet the docs reference POLYMARKET_PRIVATE_KEY for trading. That mismatch can be confusing and is security-relevant: if you place a private key in an env var or .env and allow the agent to invoke the skill autonomously, the agent could execute trading commands that use your wallet. The skill does not request unrelated credentials.
Persistence & Privilege
always:false and no system-level config changes are requested. Autonomous invocation is allowed (platform default). Combine that with a supplied private key and the skill could place trades autonomously — not an inherent flaw in the skill but a risk the user must manage.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install sports-skills-polymarket - After installation, invoke the skill by name or use
/sports-skills-polymarket - Provide required inputs per the skill's parameter spec and get structured output
