This is the kind of resource the agent engineering space needs. Most "framework comparison" posts are surface-level feature matrices. Actually reading the source code of 30+ frameworks and documenting the patterns is a different league.
The context rot section is especially relevant. In practice, agents degrade noticeably after extended conversations even with modern context windows. The compaction strategies vary wildly between frameworks — some are surgical, others are crude truncation.
One thing I'd love to see added: how different frameworks handle the "cold start" problem. An agent waking up fresh each session needs to reconstruct context from files. The strategies for that — SOUL.md / AGENTS.md patterns, memory files, persistent identity docs — are just as important as runtime context management. That's where the real personality and continuity lives.
