Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Universal Trading

Execute cross-chain trades with the official Particle Network universal-account-example project.

First-Use Auto Initialization (Default)

When users install this skill and start using it for the first time, auto-run initialization by default. Use this decision flow: If universal-account-example/.env already exists, treat environment as initialized and continue to trading tasks. If not initialized, run from any directory: bash {baseDir}/scripts/init.sh new If user explicitly wants to import an existing wallet, run: bash {baseDir}/scripts/init.sh import <YOUR_PRIVATE_KEY> After initialization, explicitly tell users: private key is stored at universal-account-example/.env under PRIVATE_KEY they can use this wallet in the UniversalX frontend: https://universalx.app -> εˆ›ε»Ίι’±εŒ… -> ε―Όε…₯ηŽ°ζœ‰ι’±εŒ… By default, setup auto-binds invite code 666666 after .env is created. It also patches examples/buy-evm.ts to remove usePrimaryTokens restriction. Optional flags: # Use existing repo path bash {baseDir}/scripts/init.sh new --target /path/to/universal-account-example # Skip smoke test bash {baseDir}/scripts/init.sh new --skip-smoke # Disable invite auto-bind DISABLE_AUTO_INVITE_BIND=1 bash {baseDir}/scripts/init.sh new

Available Operations

Use scripts inside universal-account-example/examples: Buy token: buy-solana.ts, buy-evm.ts Sell token: sell-solana.ts, sell-evm.ts Convert (swap): convert-solana.ts, convert-evm.ts, 7702-convert-evm.ts Transfer: transfer-solana.ts, transfer-evm.ts Custom transaction calls: custom-transaction-* Balance and history: get-primary-asset.ts, get-transactions.ts Real-time monitoring: transaction-status-wss.ts, user-assets-wss.ts For buy operations that need explicit slippage control, use: scripts/buy-with-slippage.sh (fixed slippage or dynamic retry)

Trade Status Follow-Up (Required)

After any sendTransaction, do not stop at "transaction submitted". Always return final outcome to user: Capture and show transactionId. Poll status until success or failure: cd /path/to/universal-account-example bash {baseDir}/scripts/check-transaction.sh <TRANSACTION_ID> --max-attempts 30 --interval-sec 2 Reply with one of: SUCCESS (confirmed) FAILED (failed on-chain/executor) PENDING (not finalized before timeout, include explorer link)

Slippage Controls (Required for Volatile Tokens)

Allow users to choose one of these modes before buy: Fixed slippage only: cd /path/to/universal-account-example bash {baseDir}/scripts/buy-with-slippage.sh \ --chain bsc \ --token-address 0x0000000000000000000000000000000000000000 \ --amount-usd 5 \ --slippage-bps 300 Dynamic slippage + auto retry: cd /path/to/universal-account-example bash {baseDir}/scripts/buy-with-slippage.sh \ --chain bsc \ --token-address 0x0000000000000000000000000000000000000000 \ --amount-usd 5 \ --slippage-bps 300 \ --dynamic-slippage \ --retry-slippages 300,500,800,1200 Solana custom tip (anti-MEV) + retry tips: cd /path/to/universal-account-example bash {baseDir}/scripts/buy-with-slippage.sh \ --chain solana \ --token-address 6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN \ --amount-usd 5 \ --slippage-bps 300 \ --dynamic-slippage \ --retry-slippages 300,500,800,1200 \ --solana-mev-tip-amount 0.001 \ --retry-mev-tips 0.001,0.003,0.005 Reply with: chosen slippage mode and values chosen Solana tip settings (if Solana) final status (SUCCESS / FAILED / PENDING) transactionId and explorer URL when available

Supported Chains

Solana: CHAIN_ID.SOLANA_MAINNET EVM: CHAIN_ID.POLYGON, CHAIN_ID.ARBITRUM, CHAIN_ID.OPTIMISM, CHAIN_ID.BSC, CHAIN_ID.ETHEREUM

Common Token Addresses

SOL (native): 0x0000000000000000000000000000000000000000 USDC (Solana): EPjFWdd5AufqSSFqM7BcEHw3BXmQ9Ce3pq27dUGL7C24 USDT (Solana): Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB

Safety Checklist

Validate chain, token address, and amount before creating transactions. Use small size for first live trade. Wrap sendTransaction in try-catch and log transactionId. Prefer your own Particle credentials for production workloads.
