Agentic Context Engine adds code-driven reflection

This is a smart mashup of two agent patterns that tackles a real bottleneck: trace review stops being useful once agents generate too much history for a human-style read-through.

• –Letting the reflector execute code over traces is a practical way to surface cross-run patterns, policy failures, and recurring mistakes that disappear in long context windows
• –The pass^k gains matter more than the headline average because they suggest the system is improving reliability, not just landing occasional lucky runs
• –The open-source framing makes this more useful than a pure research riff, especially since the repo already documents integrations with Claude Code, LangChain, and browser-use
• –It also hints at a broader shift in agent tooling: reflection is becoming an analysis pipeline problem, not just a prompt engineering problem
