I'm tired of depending on the Bundlephobia data generator so I've put an adjustment together that will use the measure script to update the package.json and eventually the README file badges.

scripts/measure.ts — Extended the existing measure script with three new behaviours:

• Run with no arguments from a package directory to measure just that package (auto-detected via CWD)
• Run with no arguments from the repo root to measure all packages at once
• --save flag writes the gzip size to primitive.gzip in each package's package.json and replaces the Bundlephobia badge in each package's README.md with a static shields.io badge

scripts/update-readme.ts — Updated to use the stored primitive.gzip value when generating the root README's Size column, falling back to Bundlephobia only when no local value exists.

scripts/utils/get-modules-data.ts — Added gzip?: number to the PrimitiveData type.

template/package.json — Added "measure" script so new packages get it automatically.

.github/workflows/tests.yml — On pushes to main only (not PRs), runs pnpm measure --save && pnpm update-readme after a green build and commits any size changes back with [skip ci].

90 packages updated — primitive.gzip written to each package.json and size badges updated in READMEs and the root README table.
