Vercel resolves vercel.json function patterns first-match-wins in
definition order, so the 60s catch-all listed above the chat route
entry swallowed it — Vercel hard-killed every agent run at 60s and
turns ended silently truncated ("Thought for 1m" with no result).
List the specific route first so its 300s budget actually applies.

Summary
The AI chat route's 300-second
maxDurationinvercel.jsonwas listed after the catch-allapp/(builder)/ycode/api/**/*.tspattern, so the catch-all's 60-second limit won and long AI chat runs were killed after a minute. Reorder the entries so the specific AI chat rule comes first and its 300-second limit actually applies.Changes
