Personal diagnosis of where your Claude Code + Cowork spend goes. Reads local transcripts, prints your conversation length distribution, marathon share, cache rebuild costs, and per-project diagnosis (good projects and problem projects) right in the terminal. Then offers a deeper dive that fans out parallel Haiku subagents over your most expensive (and most efficient) sessions and writes a tight Markdown report.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'token-doctor' ] || [ -L ~/.agents/skills/'token-doctor' ]; then echo 'A skill folder named token-doctor already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/techwolf-ai/ai-first-toolkit' "$d" && git -C "$d" checkout --quiet '2ee78415674eaaead2082a55691b68ffb1003e87' -- 'plugins/ai-adoption/skills/token-doctor' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/ai-adoption/skills/token-doctor' ~/.agents/skills/'token-doctor' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'token-doctor' ~/.claude/skills/'token-doctor' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
