This matches what we've been seeing empirically. The issue isn't just quantity of context — it's staleness. AGENTS.md and CLAUDE.md that reference renamed functions, deleted interfaces, or outdated patterns actively mislead the model with confident but wrong information.We've been auditing TypeScript repos and finding 10-84% of symbol references in AI config files are stale. A model reading a CLAUDE.md that says "use UserService.createUser()" when that function was renamed three weeks ago isn't just getting irrelevant context — it's getting a confident lie.The quality problem is probably as significant as the quantity problem, maybe more so.

Interesting. It seems to me that the right approach is to have a structured way to navigate a codebase and useful, validated docs (with examples that need to pass tests) rather than ad-hoc markdown prompts laying around and are always read. We already have solutions for this like doc comments/strings, meta data etc. The codebase itself needs to be well-maintained.
