The nexus-trading-labs skill is graded A by polygraph under litmus-skill-v2, as of 2026-06-25, anchored to its content hash.
Self-reported “Non-custodial perpetual DEX on Arbitrum with an autonomous trading agent. Use when user says buy, sell, trade, long, short, open position, close position, flip trade, set leverage, deposit USDC, withdraw funds, check balance, view positions, cancel order, copy a thesis, publish…” — the skill’s own SKILL.md description at the graded commit, not part of the grade.
A static safety grade — a deterministic scan of the skill’s SKILL.md and bundled files. An A means static-clean, not behavioral proof: a skill’s instructions are interpreted by an agent at runtime.

- What does the A skill grade mean for nexus-trading-labs?
- It’s a static safety grade(A/B/D/F) from a deterministic scan of the skill’s
SKILL.mdand bundled files. An A means static-clean — not behavioral proof, since a skill’s instructions are interpreted by an agent at runtime. - What did polygraph check?
- Three static checks: S-01 prompt-injection and context-poisoning, S-03 data-exfiltration instructions, and S-04 dangerous bundled commands. The full battery is in the methodology.
- How do I reproduce this grade?
- Run
npx -p @polygraphso/litmus polygraphso-litmus-skill <skill-dir>. The scan is open and deterministic, anchored to the skill’s content hash, so the same directory yields the same grade.
