Execute Swap

Execute a token swap on Uniswap with full safety validation.

Activation

Use this skill when the user says any of:

• "Swap X for Y"
• "Buy X with Y"
• "Sell X for Y"
• "Trade X for Y"
• "Exchange X to Y"
• "Convert X to Y"

Input Extraction

Extract these parameters from the user's message:

Workflow

1. Validate inputs: Resolve token symbols using search_tokens. Confirm chain is supported.

2. Pre-flight safety check: Call check_safety_status to verify:

   • Spending limits have room for this trade
   • Rate limits are not exhausted
   • Circuit breaker is not tripped

3. Delegate to trade-executor: Launch Task(subagent_type:trade-executor) with:

   • tokenIn, tokenOut, amount, chain
   • slippageTolerance (in bps)
   • routingPreference (auto/v2/v3/v4/uniswapx)

4. Report result to the user in a clear format:

Swap Executed Successfully

  Input:  500.00 USDC
  Output: 0.1538 WETH ($499.55)
  Price:  1 WETH = $3,248.04
  Impact: 0.01%
  Gas:    $0.42

  Safety: All 7 checks passed

Error Handling

MCP server dependency

This skill relies on Uniswap MCP tools for chain support lookup, token search, safety checks, and swap execution. When used in isolation (for example, from a skills catalog), ensure the Agentic Uniswap MCP server is running:

• Repo: Agentic-Uniswap MCP server
• Package: @agentic-uniswap/mcp-server
