Tests and debugging
“Something is broken” → the agent runs the suite, reads stdout and the stack, edits code, reruns. Returns when green.
Agent Nine runs tests, reads logs, edits code, runs migrations, and opens PRs. You frame the task — it does multi-step work instead of replying with text.
Agent Nine reads the repo, runs commands in the terminal, edits files with confirmation for every change. Trust it and it runs solo. Don’t trust it — it shows everything it’s about to do.
“Something is broken” → the agent runs the suite, reads stdout and the stack, edits code, reruns. Returns when green.

Syncs README, generates the changelog, looks at the diff, and gives a second pair of eyes on the PR before a colleague sees it.
Deploy broke — the agent opens the runner logs, finds the cause, fixes the pipeline. Hands free.
