## Limitations

- Requires nansen-cli and a valid NANSEN\_API\_KEY.
- Focuses on Polymarket prediction markets on Polygon.
- Depends on the data returned by Nansen CLI screeners.
- Does not place trades or provide financial advice.

## Best Practices

- Confirm that NANSEN\_API\_KEY is configured before running screeners.
- Start with small result limits, then expand once the market theme is clear.
- Compare volume, liquidity, and open interest before drawing conclusions.

## Anti Patterns

- Do not treat screener rankings as trading advice.
- Do not request or display raw API keys in prompts or outputs.
- Do not broaden Bash access beyond the Nansen CLI.

## Security Audit

- Audited at: 2026-07-21T03:38:10.648\+00:00
- Summary: All five external-command detections are false positives caused by Markdown inline code and fenced command examples, not executable Ruby or shell backticks. The two API-key detections document a required Nansen credential and do not show credential reading, transmission, or exfiltration within the skill file. No prompt injection or additional intent-level security issue was found.
