Sign in

tkl login
This opens the Tokenless dashboard to approve the device and stores the resulting session locally.

​
Run an agent

tkl claude

tkl codex

tkl pi

tkl opencode
tkl claude uses Tokenless’s Anthropic-compatible route; tkl codex uses its OpenAI-compatible route. tkl pi and tkl opencode use the OpenAI-compatible route too. Arguments after the agent name pass through unchanged: 
tkl claude --resume
tkl codex --help

​
Choose a routing mode

By default, tkl uses the tokenless-pro mode. Put routing flags before the agent command: 
tkl --max claude
tkl --policy ultra_saver codex
Run tkl --help for all commands and options.
