Keep CLAUDE.md to ~100 lines and load the rest on demand via skills/commands

Generative.inc·medium signal

Current Claude Code guidance flips the 'stuff everything in CLAUDE.md' habit: keep it to roughly 100 lines of essential, always-true universals and push situational detail into skills and slash-commands that load only when needed. A cited study found agents with well-crafted but lean project context hit ~90% task success vs. ~30% with none — the win is information availability at the right moment, not volume. Audit your CLAUDE.md, demote anything task-specific into a skill, and treat the top-level file as a high-signal index rather than a dumping ground.
