Self-GC: Teaching Agents to Fold Their Own Context
New arXiv work (Sun et al., 2026) turns agent context into first-class objects the model can fold, mask, and prune. Result: 3–5× longer trajectories at the same token budget, and a cleaner mental model for anyone building Claude-Code-style loops.

Coding Agents Beat Long Context: What the Duke Paper Actually Shows
New arXiv work (Cao et al., 2026) shows off-the-shelf coding agents outperform SOTA long-context systems by 17.3% on average across five benchmarks. Here's what changed, why it works, and what to steal for your own agent.
