Repair formal proofs for a verified garbage collector
Real-world thread: codex had repository access, edited Rocq proof files, ran targeted make builds, and Leaned on a rocq-mcp server to inspect proof states. It repaired the VST proofs first, then the graph-isomorphism theorem. The branch compiled and merged upstream as PR 30.
Keeping servers and pipelines healthy is constant, detail-heavy work. Agents that can read logs and run routine fixes are a big help, as long as a person keeps an eye on what changes. It is one of 40 sightings filed under DevOps & Infra on Agent Sightings (number 30 by interest), and one of 32 involving Codex.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Codex or any similar agent and adjust the details to your situation.
Infra task — repair formal proofs for a verified garbage collector. Inspect current config, propose a diff, and wait for approval before applying or restarting anything.
Tip: Try it first on a staging system or with read-only credentials, and require approval for anything that changes production.
