Your AI coding tools keep traces. Skilled reads them. Live TUI dashboard that aggregates skill usage across Claude Code, OpenCode, Codex, Grok, and Droid. Reads local history files only. Zero network, zero telemetry. Frequency counts, weekly trends, hourly distribution, per-project breakdowns, and audit heuristics (rising = 50%+ increase over 4 weeks, stale = unused 30+ days, etc.). No data leaves your machine. No accounts, no config files, no API keys.
Looking beyond Skilled? Try opencode for a terminal-first AI agent, Pieces for Developers for private, on-device coding help, and WakaTime if you want time-tracking dashboards to reveal which skills you can safely sunset.
