Etch

Etch とは？

Every AI agent decision (prompts, tool calls, edits, multi-agent handoffs) recorded into a tamper-evident, verifiable history. Debug why the agent did what it did without grepping text logs. When customers or auditors ask what your agent did on Tuesday, prove it in one link. Sits underneath whichever agent stack or context graph you already use. Works with Claude Code, Cursor, Codex, Continue, and any tool that emits webhook events.
