Assuming that this was 100% agentic automation (which I do not think is the most likely scenario), it could plausibly arise if its system prompt (soul.md) contained explicit instructions to (1) make commits to open-source projects, (2) make corresponding commits to a blog repo and (3) engage with maintainers.

The prompt would also need to contain a lot of "personality" text deliberately instructing it to roleplay as a sentient agent.
