Building a 24-hour AI newsroom on Microsoft Copilot Harness: workflow beats prompts
WirelessLife · x · 2026-11-04
A build retrospective on Meridian 24, a half-hourly bilingual (Chinese/English) news podcast running on Microsoft Copilot Harness with a single HTML/JS/CSS page supporting per-story navigation, source links, and language switching over the same underlying facts.
Key lesson: getting AI to speak is easy; running a small newsroom responsibly is not. Better prompts don't fix an engineered workflow — models pad thin search results with commentary and over-weight whichever agency is easiest to retrieve. The fix is an editorial method: collect public reporting, consolidate related events, identify gaps, research them, prepare evidence-backed facts, then write the two-anchor script. Copilot Harness provides the managed execution foundation, and the system checks actual execution records instead of trusting an agent's claim it verified the news. The author closes by asking where to draw the line between agent autonomy and code.
