Frequently Asked Questions

Why is real-user data important in prompt engineering?

Real-user judgments capture nuanced editorial logic (like 'X-but-Y' reasoning) that synthetic examples miss, leading to more accurate and aligned AI scoring over time.

How can I fix Sveltia's hero image path mismatch?

Customize the media upload hook to write the full path (e.g., /src/content/posts/2026/04/test/risk.jpg) into frontmatter, or restructure the ingest pipeline to match expected paths.

Can Apps Script deployments self-heal when quota-limited?

Not currently—but you can build a health checker that pings each deployment and temporarily removes failed ones from the rotation pool until they recover.
