History still matters. I just don't want it to be the default context for agents editing the present system.
A coding agent will read whatever you put in front of it.
That sounds like a strength. Most of the time it is the problem.
For a while my answer was "more Markdown" — CLAUDE.md, AGENTS.md, specs, ADRs, planning docs. It felt responsible: agents need context, so give them context.
Then I watched an agent do something confidently wrong because it had faithfully trusted a document that described a system we stopped having months ago. It wasn't a hallucination. It was obedience to history.
