with reviewed context.
The catalog adds a fixed-commit inventory, operating summary, prerequisites, and task-fit guidance for React 18 Upgrade.
Installation
Install React 18 Upgrade
Install from github/awesome-copilot in a compatible Agent Plugins client. Use version control and preserve a baseline test run because the workflow can make broad dependency, source, and test changes.
Terminal · Git sparse checkout
git clone --filter=blob:none --sparse https://github.com/github/awesome-copilot.git
cd awesome-copilot
git sparse-checkout set plugins/react18-upgradeUse version control and preserve a baseline test run because the workflow can make broad dependency, source, and test changes.
Review the fixed-source README and manifest before enabling the workflow.
Explainable standards check

What this catalog entry adds
This entry summarizes the fixed reviewed manifest and README without extending the upstream package's claims.
Package scope
Migrate React 16 or 17 class-component applications to React 18.3.1 with agents for audit, dependencies, class surgery, automatic batching regressions, and test repair.
Declared package inventory
Skills: react-audit-grep-patterns, react18-batching-patterns, react18-dep-compatibility, react18-enzyme-to-rtl, react18-legacy-context, react18-lifecycle-patterns, react18-string-refs
Agent resources: react18-auditor, react18-batching-fixer, react18-class-surgeon, react18-commander, react18-dep-surgeon, react18-test-guardian
Agents are listed as resources because the extension declares them separately from skills. Only the real upstream plugin.json and README.md are listed as package files.
