What is token-optimizer?

Tools for reducing the amount of text the Gemini command-line tool needs to keep in its working context. They use caching, compression, and file-reading guidance.

It helps manage cached context, compress information, and guide how large files are read in Gemini CLI projects.

Large projects can exceed an AI tool's context limit or waste space on repeated content. These tools help keep useful information available while reducing unnecessary reads.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

token-optimizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads gemini-extension.json. This mod also ships 58 executable files (hooks/lib/adapter.mjs, hooks/lib/advise.mjs, hooks/lib/audit.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to token-optimizer — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

60 files beside gemini-extension.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
