Episode notes
Prefer Spec'd Streams Over Hand-Rolled State
- Use a tested protocol and client libraries for streaming rather than hand-rolled solutions to avoid subtle resume bugs.
- Prefer a log-based stream so clients can catch up and tail instead of waiting for DB writes.
Durable Sessions And Live Demos
- Kyle demoed Durable Streams with live stream creation, JSON/text/binary modes, and YJS integration for collaborative state.
- He explained durable sessions as an experiment where all session data lives on ordered streams for multi-agent presence and replay.
Sandbox Agents And Limit Permissions
- Run coding agents inside sandboxed environments and require explicit permission for filesystem or network actions.
- Start with minimal privileges, incremental approvals, and commit history to make agent runs auditable and revertible.
