If you’ve been using Claude Code on real projects, you’ve hit the wall: the agent compacts the conversation and suddenly “forgets” half the stuff you were working on. In this video I walk through why Anthropic’s jump from 200K to 1 million tokens (Opus 4.6 + Sonnet 4.6) is a genuinely big deal—especially because it’s standard pricing across the full window. Competitors tend to double the rate once you go past ~200K tokens, so this change doesn’t just give you more room, it simplifies how you build and budget for longer-running sessions. I show practical workflows that actually benefit from the bigger window: loading beefy PRDs, CSVs, and app specs (like the ~680-line appspec from Anthropic’s repo) without doing the painful “chunk and summarize” dance that usually drops critical details. Then I go into the planning approach I use now: split the spec into features, map dependencies, and group them into implementation “waves” so work can run in parallel instead of babysitting one agent through 200–600 features. Finally, I demo Claude Code agent teams: one agent per wave, plus QA and a devil’s advocate, with cross-agent communication—and the underrated “/btw” trick so you can ask questions without interrupting work. I also explain why this matters for nasty migration projects (like a real 400+ feature rebuild) where limited context used to cause compaction and lost functionality.
