v0.2.3: document approval→wait→main-tx pattern to all agents - #11
Merged
Conversation
Agents were simulating the main tx immediately after submitting the ERC-20 approval, which fails with "insufficient allowance" because the approval isn't yet mined. The revert is misleading — it looks like a tx-builder bug. Bakes the correct sequence into two agent-facing surfaces so any MCP client (not just Claude + memory) sees it: - server `instructions`: new TWO-STEP ALLOWANCE FLOWS section telling agents to poll get_transaction_status on the approval until confirmed before simulating/sending the dependent main tx - `simulate_transaction` tool description: explicit warning not to simulate a tx whose approval is still pending Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Bakes the approval-then-wait guidance into the MCP server itself so every agent — not just ones with Claude's memory — learns the pattern.
