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!
CLAUDE_REWRITE_HISTORY=true ;)
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.
Opus 4.8 did the same at first and after it blended better the repo knowledge with the session one.
I have both $20 as I am less a power user these days and I can't justify a 100 let alone 200 but each model as its irks.
