Fixed Before Anyone Notices, Stronger After Every Fix: Self-Healing + Recurrence Prevention (Series Part 4)

Hi, I'm Ryan, CTO at airCloset.

Disclaimer: "cortex" in this article is the internal codename for an AI platform built in-house at airCloset. It is unrelated to existing commercial services like Snowflake Cortex or Palo Alto Networks Cortex.

In Part 3 I covered AI reviewing AI PRs -- the auto-review pipeline that defends quality at the PR stage.

This post is the other side: defending quality in production, via Self-Healing. A production alert fires, an AI investigates it, opens a fix PR, the PR goes through the same auto-review pipeline from Part 3, gets auto-merged and auto-redeployed. And the same fix PR is required to add a new Guide -- whether that's a lint rule, CI guard, type constraint, or guideline update -- so the same anti-pattern gets auto-rejected from then on. The guardrails grow every time.

"Incidents get fixed automatically" is catchy on its own, but on its own it's probably not enough in the long run. You have to close the recurrence class while you fix the incident -- self-healing plus self-strengthening -- before the quality gates start to compound over time.
