high confidencePurpose & Capability
Name/description (backtester) align with requested resources: it only requires VYNN_API_KEY and optionally VYNN_BASE_URL to call the Vynn API. No unrelated credentials, binaries, or config paths are requested.
Instruction Scope
SKILL.md and plugin.py explicitly send strategy text, tickers, and lookback parameters to the Vynn API (/v1/backtest). This is expected for a hosted backtest service, but users should be aware that strategy descriptions and ticker lists are transmitted to an external service (may be sensitive/intellectual property).
Install Mechanism
No install spec; this is an instruction/code-only skill. plugin.py uses only Python stdlib (urllib) and nothing is downloaded or written by an installer.
Credentials
Only VYNN_API_KEY is required (primary credential) and an optional VYNN_BASE_URL override. The requested env vars are proportional to the service being integrated; no unrelated secrets are requested.
Persistence & Privilege
Skill is not granted always:true and does not modify other skills or system-wide settings. It reads its own env vars and does not persist credentials to disk in the provided code.
Assessment
This skill appears to do what it claims, but it will transmit your strategy descriptions and ticker lists to the-vynn.com. Before installing: (1) Accept that strategy text is sent to an external service — avoid sending proprietary or confidential strategies you don't want shared. (2) Review Vynn's privacy and terms (how long they retain inputs/results). (3) Use a dedicated API key or throwaway account if you want to limit exposure and rotate the key if compromised. (4) If you have a self-hosted Vynn instance, you can set VYNN_BASE_URL to keep data in your environment. (5) Review network egress policies if running in a sensitive environment.Like a lobster shell, security has layers — review code before you run it.
