Codex + Astra: searchable notes across context windows
What happened
What happened: Alongside Astra, OpenAI updated the Codex harness for faster computer use and introduced an experimental cross-window notes/search path so long refactors don’t lose failure reasons to compaction. Tool impact: Codex becomes more competitive with Claude Code on multi-hour debugging memory—not just raw model IQ.
Tool impact
Switch or not?
Turn the experimental notes feature on for long Codex sessions this week. Switch from Claude Code only if your team is already OpenAI-native and context loss was the pain—not for a blog demo.
Money / risk
Longer surviving context + faster computer use = more tokens. Pair with rate-limit warnings and per-repo spend caps.
