Upgrade Impact Router to Module Code Owners
Maps a dependency-bump PR's affected modules to their CODEOWNERS, then DMs each owner on Slack with only the changelog slice that touches code they own.
How it runs
The automated pipeline, trigger to output.
- TriggerDependency-bump PR opened in GitHubGitHub
- ActionIdentify affected modules from changelog and importsGitHub
- LogicMap each affected module to its CODEOWNERS owner
- ActionAssemble a per-owner scoped review noteOpenAI
- OutputDM each code owner their scoped checklist on SlackSlack
What it does
This workflow routes upgrade reviews to the right people automatically. Instead of one reviewer wading through a changelog for the whole repo, it figures out which modules a bump affects, looks up each module's owner, and sends every owner a personalized Slack message covering only the parts that touch their code.
When to use it
Use it when a dependency upgrade spans modules owned by different teams and a single reviewer cannot meaningfully sign off on all of it. Best for larger codebases with a CODEOWNERS file and clear domain boundaries.
How it works
A GitHub trigger fires when a dependency-bump PR opens. The flow pulls the changelog for the version range and determines the affected internal modules by import usage. It reads the CODEOWNERS file to map each affected module to its owning team or person. For each owner, the model assembles a tailored note: the changelog items relevant to their modules, the specific call sites, and what to verify. A direct Slack message goes to each owner with a link to the PR and their scoped review checklist, so accountability lands precisely where the code lives.
