Field Notes | Vikas Kapadiya

Notes from the workbench
TypeScript edge cases, agent setups, open-source lessons, and fixes I would rather not rediscover.
0x80860010 “too many requests” when signing into a Microsoft account is a stale cached credential, not a real rate limit. Clear it with cmdkey, reboot, sign in.
Enable Touch ID for sudo in Terminal with sudo_local — or one command via Mole. Survives macOS updates; includes tmux fix.
EADDRINUSE on port 5000 is usually ControlCenter, not your app. Confirm with lsof, disable AirPlay Receiver, or move Flask, Docker, and Node off :5000.
Prefer the Claude Code harness but want a GPT model inside it? A local proxy and one alias get you claudex in about five minutes.
Codex burning through tokens on long sessions? These two config settings let you tune when it compacts your context.
If Codex subagents always match the parent model, this experimental config can expose model and reasoning controls on spawn.
One tsconfig for Vite React and Vercel /api functions was a mess. I split it into a base plus client and server configs.
