llp42 Ref to diff against: $1 (if empty, use HEAD).
- Detect which dependency manifest/lockfile files exist in the repo root (and nested dirs if relevant). Check for:
package.json+package-lock.json/pnpm-lock.yaml/yarn.lock,requirements.txt/poetry.lock/uv.lock,Cargo.toml/Cargo.lock,go.mod/go.sum,Gemfile/Gemfile.lock, and similar ecosystem files. - For each one found, run
git diff <ref-or-HEAD> -- <file>to get the changes. - Parse the diff and extract only actual dependency version changes: package name, old version → new version.
- Classify each change as major, minor, or patch bump (semver: major = first number changed, minor = second, patch = third; for non-semver ecosystems use the closest equivalent).
- Output a short plain-English bullet list, one line per changed package:
name: old → new (patch/minor/major). Group by manifest file if multiple are present. - Clearly flag any major-version bumps at the top or with a visible marker (e.g. "⚠ MAJOR") since these are more likely to be breaking.
- Do not explain what any dependency does or does research beyond the diff — only report version deltas. If no manifest/lockfile changes are found, say so briefly and stop.
