Use when a Mantle transaction needs pre-signing simulation evidence, state-diff review, revert analysis, or a WYSIWYS explanation before execution.
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
# Mantle Tx Simulator ## Overview Prepare simulation handoff packages for external backends and translate returned technical diffs into user-readable expected outcomes before signing or execution. ## Workflow 1. Normalize simulation request: - network - from/to/value/data - optional bundle/multicall context 2. Select an external simulation backend using `references/simulation-backends.md`. 3. Capture pre-state: - relevant token balances - allowance values - nonce and gas context 4. Produce an external simulation handoff package: - tx payload and network - required pre-state context - requested outputs (status/gas/logs/diffs) 5. After external execution evidence is provided, collect: - success/revert - gas estimate - logs/events - state diffs 6. Convert technical result into WYSIWYS summary with `references/wysiwys-template.md`. - **ALWAYS produce a WYSIWYS section**, even before external simulation results arrive. - If no external evidence exists yet, produce a **preliminary WYSIWYS** based on the request parameters, clearly labeled: "PRELIMINARY — not yet verified by simulation." …

How to install
mdr add starchild-ai-agent/official-skills/mantle-tx-simulator@sha256:0f148037eebb46feThe line at the top of this page pins the label git:20260410.7fb1a6e, 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.
