Stop Wasting Tokens on npm Install Noise

Run npm install in a medium-sized project. Count the deprecation warnings.

I counted 47 in one project. Each one says something like "This module is not supported and is kept for compatibility." Claude Code reads all 47. They're identical in meaning. They cost tokens. They push your actual code out of the context window.

What npm Install Actually Outputs

npm warn deprecated inflight@1.0.6: This module is not supported...
npm warn deprecated @humanwhocodes/config-array@0.11.14: Use @eslint/config-array
npm warn deprecated rimraf@3.0.2: Rimraf versions prior to v4 are no longer supported
npm warn deprecated @humanwhocodes/object-schema@2.0.3: Use @eslint/object-schema
npm warn deprecated glob@7.2.3: Glob versions prior to v9 are no longer supported
npm warn deprecated eslint@8.57.1: This version is no longer supported...

💾 contextzip: 89,241 → 8,102 chars (91% saved)

91% reduction. 47 deprecation warnings → gone. Progress bars → gone. ANSI escape codes → gone. The install result is preserved.

Install

cargo install contextzip
eval "$(contextzip init)"

No config. No per-project setup. It just works as a transparent shell proxy.
