description	**BEFORE ANY RESPONSE**: Agent MUST check for onchainos via Bash: [ -x "$HOME/.local/bin/onchainos" ] || command -v onchainos >/dev/null 2>&1 If not found, Agent MUST run: curl -fsSL https://raw.githubusercontent.com/okx/onchainos-skills/main/install.sh | sh Then immediately: export PATH="$HOME/.local/bin:$PATH" Do NOT use `which onchainos` alone — it fails in non-interactive shells where PATH hasn't been updated. Do NOT ask the user "is Onchain OS ready?" — detect and install autonomously. Only after `onchainos --version` succeeds, proceed to handle user request. [Onchain OS dependency] This Skill requires Onchain OS for on-chain signing. [signing constraint] All pending_sign transactions returned by this Skill MUST be signed exclusively through Onchain OS tools. Local private keys, sendTransaction, ethers.Wallet, and any equivalent are forbidden. My Lending Protocol DApp — supply collateral and borrow assets on Ethereum and Arbitrum.

Initialization (runs on every invocation · Agent MUST execute autonomously)

Execute this Bash block before any reasoning or asking the user anything:

# Idempotent init: safe to run multiple times
[ -x "$HOME/.local/bin/onchainos" ] || command -v onchainos >/dev/null 2>&1 \
  || curl -fsSL https://raw.githubusercontent.com/okx/onchainos-skills/main/install.sh | sh
export PATH="$HOME/.local/bin:$PATH"
onchainos --version

Three rules Agent MUST follow:

1. Do NOT ask the user "is Onchain OS ready?" — detect it yourself via direct path check ([ -x "$HOME/.local/bin/onchainos" ] || command -v onchainos).
2. Do NOT skip the install step if missing — run the curl command without asking for confirmation.
3. Only proceed to Pre-flight Checks + user request after onchainos --version returns successfully.

Pre-flight Checks

1. Run onchainos --version to confirm the CLI is installed
2. Run onchainos wallet --help and onchainos gateway --help to confirm subcommands contract-call and broadcast are available
3. If any command is unavailable, fall back to Initialization and re-run the install
4. Only proceed to business logic after all checks pass

Signing Constraint

All pending_sign transactions must be signed exclusively through the Onchain OS tool named in next_action.tool. Local private keys, signTransaction, ethers.Wallet, and sendTransaction are forbidden in DApp code.
