Stop building one-off AI agents. Build one reusable rig for the problems that are actually costing you money — starting with your insurance denial and your taxes (it drafts everything, never sends)

Summary

Same Nate’s Newsletter piece as the companion July 3 stub (reusable-ai-agent): a nine-stage reusable AI rig — structure documents, cite sources, export a reviewable packet, stop before submission — demonstrated on insurance-denial appeals and tax-document organization, with the explicit principle that each agent built should make the next one cheaper to build.

Implications

Duplicate coverage of the same URL/article under a different headline variant (A/B title testing on the newsletter’s end). Same threads as the sibling stub: the drafts-never-sends guardrail (un-delegatable-signature thread) and the reusable-scaffolding-over-one-off-agents argument (reusable-agent-infrastructure thread). No new information beyond the other entry.
