Getting Started

Install (Claude Code, via the 88plug marketplace)

# 1. Add the marketplace (once per machine)
/plugin marketplace add 88plug/claude-code-plugins

# 2. Install this plugin
/plugin install use-latest-version@88plug

That is all. No environment variables, no API keys. On first launch the plugin compiles itself and starts the MCP server automatically.

First calls

Ask your assistant things like:

• "What's the latest version of express on npm?" -> get_latest_version
• "Is requests==2.28.0 current?" -> compare_versions
• "Scan this project and tell me what's outdated." -> check_outdated
• "Plan an upgrade for this repo, then show me the diff before applying." -> optimize_versions -> validate_upgrade_plan -> apply_upgrades (dry run)

The upgrade pipeline

The four project tools are designed to chain:

1. optimize_versions — scans the project and returns a plan (per dependency: keep / upgrade / downgrade / remove, with risk).
2. validate_upgrade_plan — checks that plan for breaking (major) bumps, circular dependencies, and constraint violations.
3. apply_upgrades — writes the plan to the manifests. Defaults to a dry run; pass dry_run: false to actually write. Backs up every file first.

See the Tool Reference for every tool and its arguments.
