Migrate a password reset flow to modern libraries

According to the write-up, powered by work API tokens, the developer first assembled a plan with the Claude Code harness, then had Claude Code with the latest Opus migrate a web app's password reset flow from legacy libraries and architecture to modern ones. He supervised closely, reviewing every proposal, and afterward spent significant time cleaning up the final output. Code was decent at small scale but architecturally off, and it drifted into unrelated changes.
