Why it matters
Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 106 sightings filed under Software Development on Agent Sightings (number 97 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.
Search public GitHub for repos that appear to commit API keys or tokens and also show evidence of coding-agent use. Rank the top 20 by priority and include a LinkedIn URL when you can find one.
Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
