# 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) |
|
|
|
|
```bash
|
|
# 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:
|
|
|
|
```bash
|
|
rtk proxy make install # runs make install, tracks usage, no filtering
|
|
```
|
|
|
|
To check which commands were missed opportunities: `rtk discover`.
