CONTRIBUTING.md says pnpm 8.15.7+, but pnpm-lock.yaml v9.0 + packageManager [email protected]

Problem

.github/CONTRIBUTING.md tells new contributors to install pnpm version 8.15.7 or higher, but the repo's lockfile requires pnpm 9+ and package.json pins pnpm 10.

Cite

• .github/CONTRIBUTING.md line 37: "pnpm (version 8.15.7 or higher)"
• package.json line 20: "packageManager": "[email protected]+sha512..."
• pnpm-lock.yaml line 1: lockfileVersion: '9.0'

Steps

1. npm i -g [email protected] (following CONTRIBUTING)
2. git clone https://github.com/idosal/git-mcp && cd git-mcp
3. pnpm install

Expected

Install succeeds.

Actual

pnpm 8 cannot parse lockfileVersion: 9.0. Either corepack silently upgrades to pnpm 10 (making the 8.15.7 guidance misleading), or the install fails outright with a lockfile-version error.

Environment

• Repo default branch main @ HEAD as of 2026-07-04
• package.json packageManager: [email protected]
• pnpm-lock.yaml lockfileVersion: 9.0

Fix

Update CONTRIBUTING.md prerequisite to pnpm 10.x (or 9+), matching the pinned packageManager. One-line docs change.

Thanks for maintaining idosal/git-mcp!
