Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Nexus Trading Labs — Agent Skill
## ⚠️ CRITICAL — READ THIS BEFORE ANYTHING ELSE
**Every authenticated action requires a wallet signature. Get it once, reuse for the session.**
```
Step 1 — request_additional_tools({ names: ["sign_message"] })
Step 2 — commit_to_tools({ keep: ["sign_message"] })
Step 3 — sign_message({ message: "nexus-trading-key-v1" }) → save as walletSig
also capture walletAddress from the connected wallet
```
**⛔ DO NOT skip this.** No walletSig = 401 error on every authenticated endpoint.
**⛔ DO NOT ask the user for a signature.** You have `sign_message` — use it yourself.
---
## ⛔ FORBIDDEN
- NEVER call `trade.nexustradinglabs.com` for API requests — that is the static frontend app. It returns 405 on all POSTs.
- NEVER prepend `/api/` or `/api/v1/` to endpoint paths — there is no such prefix on this API.
- NEVER construct URLs from relative paths — always use the full URL from the quick reference table.
- NEVER embed `stopLoss` / `takeProfit` in the `/trade` body — place them via `/set-sl-tp` after fill
- NEVER store or log the Bankr API key — use it transiently per call, never persist

How to install
mdr add bankrbot/skills/nexus@sha256:d341dbcffef7cfe9The line at the top of this page pins the label git:20261014.55a5656, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
