Diff Digest compares two text blobs and returns a human-readable change summary plus structured changes[] and risk_flags[] (breaking, auth, data, deps, config). Use it before merges, after tool rewrites, or in agent review loops so risky diffs surface with evidence instead of silent drift. Single tool digest_diff. Settled in USDC on Base (mainnet) at $0.05 per call.
