Before You Send: Transaction Safety Pair
Two independent checks for anyone letting an agent touch real money or sign real transactions. evm-transaction-dry-run simulates a specific on-chain transaction on a forked node before broadcast — REVERT/RISK/SIMULATED-OK, never "safe to send." money-agent-safety-harness is the separate, upstream question: before an autonomous agent moves real funds at all, a 6-layer containment gate on blast radius (not strategy quality) — what stops it when it's wrong, not whether it's profitable. Together they cover the two moments that actually matter: is this agent safe to run live at all, and is this specific transaction safe to send. Neither one substitutes for the other — that's why they're sold as a pair, not merged into one skill.
Works with every agent that reads SKILL.md — Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Windsurf, OpenClaw, and more.
