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.

Why it matters
Notes are only useful if you can find and connect them later. Agents that organise, summarise and link information make a personal knowledge base far easier to keep up. It is one of 44 sightings filed under Knowledge & Notes on Agent Sightings (number 41 by interest), and one of 164 involving Claude Code.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude Code or any similar agent and adjust the details to your situation.
Notes task: migrate a password reset flow to modern libraries. Propose edits as a checklist, apply after approval, and finish with a short handover.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
