Install as codex-shake beside your official codex (pick one):

Homebrew (macOS Apple Silicon, or Linux x86_64):

brew install epsalmond/codex-shake/codex-shake

Debian/Ubuntu (x86_64), download and install the .deb from this release:

curl -fsSL -o codex-shake_0.154.0+r20260917020207.00000000000028b70f23268b5dc8_amd64.deb \

sudo dpkg -i codex-shake_0.154.0+r20260917020207.00000000000028b70f23268b5dc8_amd64.deb

curl | sh (any supported platform, installs to ~/.local):

curl -fsSL https://raw.githubusercontent.com/epsalmond/codex/eric/local-features/install.sh | sh

Run codex-shake. To update: codex-shake-update (curl|sh installs),
brew upgrade epsalmond/codex-shake/codex-shake (Homebrew), or reinstall the
.deb for the latest release (Debian/Ubuntu).

Binaries are stripped; debug symbols are attached as
codex-symbols-<target>.tar.gz (.debug files for Linux, .dSYM
bundles for macOS) if you need to symbolicate a crash.

Release provenance

  • Source: validated branch merge (fork snapshot)
  • Workspace version: 0.154.0
  • Fork release commit: 0f23268b5dc880d380c3b7cafc18663150476473
  • Integrated upstream main commit: 5b1d6560181680f95cde95c14ed042acc02248ed
  • Exact stable lineage: rust-v0.154.0

Codex Shake keeps long coding sessions smaller by removing older tool output
from active context. In our replay benchmark, shaken runs used 2.3–2.7× fewer
Codex credits.

Surviving conversation content stays byte-identical, and removed content remains
available in local artifact files. Auto-shake runs by default; /shake lets you
preview and trigger it yourself.

The published replay reduced active history from 536k to 176k tokens. Its
measured results were:

arm active history standard Codex credits end state
full history, cold cache 536k 840 12/12
shaken, cold cache 176k 312 11/12
full history, warm cache 536k 809 12/12
shaken, warm cache 176k 358 12/12

This was n=1 per cell, with builds stubbed; the one cold shaken run missed one
structural check. An earlier replay projected 4.8x lower API cost using the API
rate card ($59.46/$12.37); it used 2.42× fewer Codex credits.

No artifact recovery reads were observed in the nine runs covered by the
recovery report. Cache behavior and savings vary by workload; see the
benchmark methodology.

The weekly projection estimated 2.04B fewer input tokens out of 12.37B across
182 historical threads. It is a projection from rollouts, not a plan-quota
measurement.

Based on upstream rust-v0.154.0 (exact stable lineage; the included
upstream-main SHA is recorded separately above). Apple Silicon and x86_64
Linux (glibc >= 2.35), unsigned, unstripped.

local-features-v0.154.0-r202609131748.1d7e5d832c16
1d7e5d8

Test builds of Codex with shake, a context reducer that cuts instead of summarizing.

What it does. Compaction replaces the history with a model-written summary. Shake removes the parts of the history that are almost never needed again: old tool output, images, thinking. Each removed item is written to a file under $CODEX_HOME/artifacts/ and the placeholder names the path. The rest of the thread is untouched.

Why it helps. Every request re-sends the whole history, and gpt-5.6 charges a long-context premium above 272k input tokens. A thread that shakes at 160k stays below that line, and every request after the shake is a fraction of the size.

What it costs. One uncached request of the surviving history. The thread is fully cached again on the next request.

What was measured, replaying a real 536k-token session from a frozen checkpoint:

  • Shaken threads reach the same end state at 2.3x to 2.7x fewer credits.
  • Nothing elided is ever read back: zero reads in nine benchmark runs and zero across 346 oh-my-pi sessions. So there is no read tool, only the path.
  • Plan quota meters total input tokens, not uncached tokens. Warming the cache does not save quota. Shrinking the prompt does.
  • Over one busy week of real rollouts, auto-shake would have cut 2.0B of 12.4B input tokens.

Auto-shake is on by default in this build: at 160k tokens on gpt-5.6, at 40% of the window on Astra, and on any resume after the prompt cache has expired. /shake in the TUI does it by hand, with a preview.

Based on upstream rust-v0.154.0 (1d7e5d832c16). Apple Silicon and x86_64 Linux
(glibc >= 2.35), unsigned, unstripped.

local-features-v0.154.0-ee79c53c4201
ee79c53

Prebuilt test binaries for the eric/local-features branch: statusline reset + response
clock, surgical context-reduction shake with preview and cost estimate, and
per-thread recoverable artifacts. Based on upstream rust-v0.154.0 at
ee79c53c4201.

Install as codex-next beside your official codex (rerun to update):

curl -fsSL https://raw.githubusercontent.com/epsalmond/codex/eric/local-features/install.sh | sh
codex-next --version   # expect: codex-cli 0.154.0

The installer picks your platform, verifies SHA256SUMS, and clears the macOS
quarantine flag (these builds are unsigned). Manual install: untar, keep
codex-code-mode-host next to codex. The Linux build is glibc-linked
(needs glibc >= 2.39), not musl like upstream releases. Binaries are
unstripped, hence the size.

What to try

  • /shake in the TUI, then pick a mode: elide tool outputs, drop images, or
    drop thinking. Elide saves recovery artifacts the model can read back later;
    no config flag needed. Preview shows the estimated token savings first.
  • /statusline and add the new weekly-reset and last-response-clock
    items. They are off until you select them.
  • App-server users: thread/shake/preview and thread/shake/start are
    documented in codex-rs/app-server/README.md on this branch.

Feedback: open an issue on this fork or ping Eric directly. Only Apple Silicon
and x86_64 Linux builds are published; ask if you need Intel Mac.
