Economy model routing — claudectl's own internal Claude calls (memory extraction, lessons, CLAUDE.md / agent / hook / skill generation) default to Haiku to cut cost, while your actual coding sessions keep whatever model you choose. Change it in ⚙ Settings → Economy model (extract_model).
Skills manager — browse, install, scaffold, and AI-generate Claude Code skills (.claude/skills/<name>/SKILL.md) that load on demand instead of bloating CLAUDE.md. Ships with cited starter templates (see Credits). TUI: ⚙ Skills; GUI: the Skills tab.
Code review — claudectl review [--staged] [--branch <base>] reviews your working diff against your CLAUDE.md rules + learned memory lessons and reports confidence-scored findings (only ≥80% shown). Also on the project Review tab (GUI) and the ⇧R key in the session menu.
Recent-work memory — opt-in per project (Memory tab / ⇧W in the hub). Records a token-free one-line summary + files touched at the end of each session and injects a compact digest on the next SessionStart, so Claude knows what the last few sessions did.
