Fewer than 1% of denied insurance claims get appealed, and a third to half of appeals win. Build the AI rig that turns your denial and tax pile into cited packets — it drafts, never sends.

Summary

Nate’s Newsletter proposes a single reusable AI “rig” — a nine-stage pattern that structures messy documents, cites sources rigorously, and exports a reviewable packet — applied first to drafting insurance-denial appeal packets (fewer than 1% of denials are appealed today, despite a third-to-half win rate) and then reused unchanged for organizing tax documents. The agent drafts and organizes only; it never submits, files, or sends.

Implications

• Un-delegatable-signature thread: the “drafts, never sends” guardrail is the same submission/approval boundary this radar has tracked through the CC autonomy-sprint releases (an agent’s output is not authorization to act).
• Reusable-agent-infrastructure thread: “every agent you build should make your next agent cheaper to build” — the flywheel argument for investing in shared agent scaffolding rather than one-off builds, relevant to any project standardizing on a small number of agent patterns rather than bespoke automations per task.
