In my case, since "new session" Claude couldn't understand it either, I assume it means it's going to contribute significantly to context rot. In your case, it probably results in a lower quality context.

Hey Anthropic, give agents/skills the ability to modify previous context! This could be used to truly clean reasoning and task definition mistakes, corrected by the user, and strip output to more fundamentals, which should strengthen/purify the context!

Editing agents, and my own, messages is still how I get the best results for high reasoning planning, in chat clients. I remove the mistakes, because I naively assume that if your context has mistakes, now your next token prediction will be biased to a space where the AI makes mistakes! It would be interesting to write some benchmarks around this, but I've seen significant differences when I do this for less capable models.
