Stack Modernization

Keep a project on current, minimal, idiomatic dependencies. Three jobs: upgrade what is behind, delete what is unused, and migrate patterns a major upgrade left stranded (the v3 config still sitting in a v4 repo). Edits package.json and source, so it runs behind a confirmation gate and verifies before it upgrades.

Never trust training data for a version number — the current latest is looked up, not recalled.

Authorized Scope

Apply this engine only within the user's requested task and existing explicit authorization. Loading or delegating to it grants no additional authority. Preserve report-only restrictions and the caller's target, host, provider, and cost limits. Existing approval satisfies a gate only for the same actions and scope; obtain approval before expanding them. Forward these limits to delegates.
