Dependency Upgrade Impact Briefer on Renovate PRs

When a dependency-bump PR opens, reads the package changelog diff, finds which internal modules import that package, and posts a plain-English impact brief as a PR comment.

What it does

This workflow turns every Renovate or Dependabot version-bump PR into a readable impact brief instead of a wall of lockfile noise. It fetches the changelog between the old and new versions, identifies which files in your repo actually import the upgraded package, and posts a comment summarizing what changed, what it touches, and where a reviewer should look first.

When to use it

Use it when bot-opened upgrade PRs get rubber-stamped or ignored because nobody wants to diff a changelog by hand. Best for teams running automated dependency bumps who want a human-readable risk note attached to each one before merge.

How it works

A GitHub trigger fires when a PR labeled as a dependency bump is opened. The flow parses the package name and the from/to versions from the PR, then pulls the upstream changelog or release notes for that range. It greps the repository for files importing the package to build the affected-module list. The model condenses the changelog diff into breaking changes, deprecations, and behavior shifts, mapped against the modules that use them. The brief is posted as a single PR comment with a suggested review focus.
