Skills
Run a monthly skill audit — delete any skill you haven't triggered in 30 days, keep 8–12
As the Claude Code skills ecosystem flooded in 2026, the winning move is to treat your skill folder like a dotfiles repo: small, opinionated, version-controlled, and always shrinking. Every loaded skill consumes context tokens whether or not it fires, so eight to twelve well-chosen skills cover most of a senior developer's day and more just adds context tax. The concrete practice: audit monthly and delete anything you haven't triggered in thirty days, biasing toward workhorse skills (code review, git, docs, env debugging) over speculative ones.
