Monorepo Shared-Library Bump Fan-Out

When a shared internal library publishes a new version, this finds every package in the monorepo that consumes it, stages a single coordinated bump PR per affected package group.

What it does

Coordinates internal library upgrades across a monorepo. When a shared package cuts a release, it walks the workspace dependency graph to find every consumer, then stages bump pull requests grouped so related packages move together rather than drifting.

When to use it

Use it when a core internal package (a UI kit, a client SDK, a types library) ships a new version and you want all consumers on it quickly without hand-editing dozens of manifests. Ideal for Turborepo or pnpm-workspace setups.

How it works

  1. 1A GitHub release event for the shared library triggers the flow.
  2. 2The agent reads the workspace manifest and builds the internal dependency graph to find all direct and downstream consumers of the library.
  3. 3A grouping step clusters consumers into batches that should upgrade atomically based on their interdependencies.
  4. 4It opens one bump PR per batch, updating every manifest in that group to the new version.
  5. 5It posts the rendered dependency fan-out graph and the list of staged PRs to Slack so reviewers see the upgrade order at a glance.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect GitHubRepos, issues, pull requests, actions.
  2. 2
    Connect SlackChannels, DMs, threads, mentions.
  3. 3
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  4. 4
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  5. 5
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
