---

Every npm test, cargo build, git log or grep -rn your agent runs pours its full output into the context window: passing tests, progress bars, compile lines, the same warning 400 times. Tokmizer sits between the command and the model and hands over what matters: the failures, the diagnostics, the result. The full output stays one command away.

Before and after

cargo test with three failing tests (fixture).

Before: 42 lines, 1,102 bytes. Compile lines, every passing test, panic headers, a backtrace hint, and the failure list printed twice.

After: 11 lines, 382 bytes.

× tests::truthy src/lib.rs:12:27
  assertion failed: add(0, 0) > 0
× tests::big src/lib.rs:10:24
  assertion `left == right` failed: adding 6 and 1
    left: 8
   right: 7
× tests::empty src/lib.rs:2:34
  index out of bounds: the len is 0 but the index is 0
test result: FAILED. 4 passed; 3 failed; 0 ignored; 0 measured; 0 filtered out
error: test failed, to rerun pass `--lib`

Every assertion, location and value is still there.

Numbers

68 real command outputs replayed offline through each tool's Claude Code hooks (Tokmizer 0.9.71 and rtk 1.0.1 with default settings, o200k_base tokenizer, median of 3 runs, 2026-10-19):

	Tokmizer, Claude Code default mode	Tokmizer, commands rewritten	rtk 1.0.1
Tokens removed	93.0%	94.3%	55.5%
Failure details kept, out of 307	307	307	133
Failing runs that lost a detail, out of 26	0	0	10
Cuts without a marker	none found	none found	found

• Claude Code's own Read, Grep and Glob tools are shortened too: large file reads −62% to −91%, grep −27% to −94%, glob −70%. Smaller code files stay whole.
• The hook that runs before each command takes about 3 ms with the native launcher, against 11 to 17 ms for rtk (measured 2026-10-16).

These figures count command output, not your bill, task success or speed. Small outputs gain less: 51% on the outputs under 30,000 characters. Method, every case and the raw JSON: tokmizer.com/en/compare/rtk. A public benchmark you can replay yourself: BENCHMARK.md.

Install

Claude Code

/plugin marketplace add norwelltw/Tokmizer
/plugin install tokmizer@tokmizer

Restart Claude Code once (hooks load at startup), then run /tkr-status. You should see Status active.

Every other agent

Install the CLI, then let tkr setup --all hook every agent it finds on this machine:

curl -fsSL https://tokmizer.com/install.sh | bash
tkr setup --all

The script uses npm when a patched Node.js (24.22.1+, or 22.23.4+) is installed, and otherwise downloads a standalone build for macOS or Linux after checking its signature and SHA-256. Your shell profile is not touched.

<table> <tr><td><b>npm</b></td><td>

npm install -g @tokmizer/plugin
tkr setup --all

</td></tr> <tr><td><b>Homebrew</b></td><td>

brew install norwelltw/tokmizer/tokmizer
tkr setup --all

</td></tr> <tr><td><b>Windows</b><br>PowerShell</td><td>

npm.cmd install -g @tokmizer/plugin
tkr.cmd setup --all

</td></tr> </table>

tkr setup without --all lists what it found and asks. Restart each agent after setup, then run tkr status. Installed with npm or Homebrew, tkr updates itself 24 hours after a version ships; tkr auto-update off stops that.

Every setup command keeps your other hooks and settings, saves the file as it was in ~/.tokmizer/backup/config/, and takes itself out with --remove. If tkr is missing, slow or fails, the command runs exactly as typed.…
