Commands and ecosystems automatically optimized by RTK with typical token savings

What RTK Optimizes
Once RTK is installed with a hook, these commands are automatically intercepted and filtered. You run them normally — the hook rewrites them transparently before execution.
Typical savings: 60-99%.

Global flags
These flags apply to all RTK commands and can push savings even higher:
Flag
Description
--ultra-compact
ASCII icons, inline format — extra token reduction on top of normal filtering
-v / --verbose
Show filtering details on stderr (-v, -vv, -vvv for increasing detail)
# Ultra-compact: even smaller output
rtk git log --ultra-compact
# Debug: see what RTK is doing
rtk git status -vvv
:::note
Use --ultra-compact (long form) rather than -u when working with Git commands. Git's own -u flag means --set-upstream and the short form can cause confusion.
:::
Commands that are not rewritten
If a command isn't in the list above, RTK runs it through passthrough — the output reaches the LLM unchanged. You can explicitly track unsupported commands:
rtk proxy make install # runs make install, tracks usage, no filtering
To check which commands were missed opportunities: rtk discover.
