Why Claude gets dumber the longer you use it - and how to fix it

There's a name for what happens when Claude starts losing the plot halfway through your session.

It's called context rot.

Every tool call, every file read, every result - it fills up a window. After 30-40 minutes of real work, 40% of that window is already gone. Claude is working with stale data. It starts contradicting itself. Forgetting what you told it. Giving you garbage.

It's not a bug. It's just how these models work.

Friday we covered three skills that solve it:

GSD (Get Shit Done) - each task gets its own fresh sub-agent. Like giving each job its own office instead of stacking everything into one room.
- Context Mode - compresses a 315KB tool output down to 5.4KB before it hits your context. Same information. Fraction of the cost.
- Claude Mem - persistent memory across sessions. Claude wakes up next week knowing exactly what you were building.

The contractor forgets you between gigs. The employee remembers.

That's the difference.
