Charlie Marsh says he spent the weekend optimizing Codex, and the screenshot shows a long run of merged PRs focused on TUI and markdown/runtime efficiency.
- The image lists many recent fixes and optimizations: audio history tests, conversation history snapshots, WebSocket payload handling, TUI rendering, markdown wrapping, caching, and duplicate metadata reads.
- It reads like an active engineering push to reduce redundant work and clean up agent/UI state handling across the Codex stack.
