Jmerta Codex Skills Dependency Upgrader

Dependency upgrader

Goal

Safely upgrade dependencies with minimal, reviewable diffs and clear verification.

Inputs to ask for (if missing)

• Which ecosystem: Gradle/Maven, Node/TypeScript, or both.
• Scope: one dependency, a set (e.g., Spring Boot), or "everything".
• Constraints: patch/minor only vs allow majors; time budget; CI requirements.
• Motivation: CVE fix, feature need, or routine maintenance.
• Can the agent use web search to confirm latest versions and read migration notes? (If not, rely on registry lookups.)

Workflow (checklist)

1. Detect the project type and package manager
   • Node: package.json + lock file (pnpm-lock.yaml, package-lock.json, yarn.lock, bun.lock).
   • Gradle: gradlew, build.gradle(.kts), settings.gradle(.kts), gradle/libs.versions.toml.
   • Maven: pom.xml.
   • If the required package manager or build tool is missing (npm/pnpm/yarn/bun, Gradle, Maven), tell the user and ask whether to install it or proceed with a manual edit-only upgrade.
2. Establish a baseline
   • Record current versions (dependency file + lock files).
   • Run the smallest reliable test/build command the repo uses (then expand if needed).
3. Plan the upgrade
   • Prefer the smallest bump that solves the problem.
   • Choose target versions using up-to-date sources:
     • Use web search (if available) to confirm latest stable versions and skim official release notes/migration guides.
     • Cross-check with the registry/source of truth (npm registry, Maven Central, Gradle Plugin Portal).
   • Group by risk:
     • low: patches/minors, leaf deps
     • medium: build tools/plugins
     • high: framework majors (Spring Boot), runtime bumps (Java/Node)
   • For majors: skim upstream migration notes and list expected breakpoints before editing.
4. Apply upgrades incrementally
   • Update one group at a time; keep diffs focused.
   • After each group: run tests/build and fix breakages immediately.
   • Use the playbooks in references/ for ecosystem-specific commands.
5. Validate and document
   • Run the repo's "CI equivalent" commands (tests + build).
   • Document:
     • what changed (versions)
     • why (CVE, compatibility, feature)
     • notable migrations or breaking changes
     • any follow-ups (deprecations, future majors)

Deliverable

Provide:

• The list of version bumps (old -> new).
• The commands run and their result (tests/build).
• Any breaking changes and required code/config migrations.
