`tokenmonitor` reads the session logs your AI CLIs already write to disk and reports token usage and estimated spend across all of them:

Tool	Logs read	Notes
Claude Code	`~/.claude/projects/*/.jsonl` (`$CLAUDE_CONFIG_DIR` overrides)	dedupes resumed sessions; 5m/1h cache-write TTLs priced separately
OpenAI Codex CLI	`$CODEX_HOME/sessions` (default `~/.codex/sessions`)	per-request deltas; cached input priced at the discounted rate
Gemini CLI	`$GEMINI_DIR` (default `~/.gemini`)	best-effort scan of session metrics and chat transcripts

No API keys, no accounts, no telemetry, no network calls — it never leaves your machine.
