Polymarket

Query Polymarket prediction markets. Check odds, find trending markets, search events, track price movements.

Security Scan

The skill's code, instructions, and requirements are consistent with a read-only Polymarket query and local paper-trading tool that stores data under ~/.polymarket and does not request credentials or external access beyond Polymarket's public API.

Purpose & Capability

Name/description promise (query Polymarket, trending, alerts, paper trading) matches the included script and SKILL.md. Minor mismatch: the script declares a Python dependency on the 'requests' library (in a comment header) but the registry metadata only requires 'python3' as a binary; no install step is provided to install requests. Functionality otherwise aligns with the stated purpose.

Instruction Scope

SKILL.md instructs only to run the bundled Python script and schedule it via cron. It documents that the skill performs HTTPS GETs to the public Gamma API, stores watchlist/portfolio JSON in ~/.polymarket, and does not access wallets or credentials. No instructions ask the agent to read unrelated system files, transmit data to unknown endpoints, or escalate privileges.

Install Mechanism

No install spec (instruction-only) — lowest-risk approach. The bundle includes a Python script that depends on 'requests' (commented in file). Because there's no install step, users must ensure dependencies (e.g., pip install requests) themselves; the lack of an explicit install step is a usability/security note but not malicious.

Credentials

No environment variables, credentials, or config paths requested. The skill only stores local JSON under the user's home (~/.polymarket) which is consistent with the described watchlist and paper-trading features. No unexplained secrets or unrelated service tokens are requested.

Persistence & Privilege

always is false and disable-model-invocation is true (agent won't autonomously call it), so it has no elevated persistent privileges. The script writes only to its own data directory (~/.polymarket) and does not attempt to modify other skills or system-wide agent settings.

Assessment

This skill appears to do what it says: read public Polymarket data and maintain a local paper-trading/watchlist state in ~/.polymarket. Before installing or running: 1) Inspect the bundled scripts yourself (they are included). 2) Ensure Python and the required Python packages (notably 'requests') are installed in a controlled environment or virtualenv; the registry only lists python3 as a binary but the script needs requests. 3) Be aware the tool writes JSON files to ~/.polymarket (watchlist.json, portfolio.json) — back up or review those files if needed. 4) The SKILL.md links to an external Telegra.ph guide; do not run any commands from that guide unless you trust the source. 5) If you plan to run scheduled cron jobs, run them under a user account and consider redirecting output to logs you control. If you want higher assurance, run the script in an isolated environment (container or VM) and audit network activity to confirm it only contacts gamma-api.polymarket.com.

API

Uses the public Gamma API (no auth required for reading):

• Base URL: https://gamma-api.polymarket.com
• Docs: https://docs.polymarket.com

---

Security & Permissions

No API key or authentication required. This skill uses Polymarket's public Gamma API.

What this skill does:

• Makes HTTPS GET requests to gamma-api.polymarket.com (public, unauthenticated)
• Reads market data: odds, volumes, event details, price history
• Paper trading is local simulation only — stored in ~/.polymarket/ as JSON files
• No real money, no wallet, no blockchain transactions

What this skill does NOT do:

• Does not connect to any wallet or financial account
• Does not execute real trades or transactions
• Does not require or handle any credentials or API keys
• Does not send any personal data externally
• Cannot be invoked autonomously by the agent (disable-model-invocation: true)

Data stored locally: ~/.polymarket/watchlist.json, ~/.polymarket/portfolio.json

Review scripts/polymarket.py before first use to verify behavior.

Note

This is read-only + paper trading. Real trading requires wallet authentication (not implemented).
