pi: auto-retry stalled requests

♠ Previously. Problem statement: sometimes a prompt in pi just hangs, as if the network dropped. It never recovers on its own — I have to hit Esc and re-prompt. It’s 2026, this symptom should be self-recoverable. Pi already has agent-level retry on transient errors (retry.enabled defaults to true). The catch is when it fires: a stalled connection isn’t an error until the HTTP idle timeout trips, and that defaults to five minutes: httpIdleTimeoutMs | number | 300000 | HTTP header/body idle timeout in milliseconds […] Set to 0 to disable. So pi would have eventually recovered. I was just quitting long before the five-minute clock ran out. Who has patience to wait for 5 minutes?! :∴ Lower the idle timeout to O(seconds) instead: { "httpIdleTimeoutMs": 30000, "retry": { "enabled": true, "maxRetries": 5, "baseDelayMs": 2000 } } Dropped into ~/.pi/agent/settings.json, documented in docs/settings.md. Now a stall errors out after 30s and pi retries automatically with exponential backoff (2s,…
