Meet update-dependencies: Streamline Flutter Monorepo

Where this fits

It's Monday morning. You're on the Sesori Apps team, and your Flutter monorepo has 15 pubspec.yaml files, two Dart workspaces, and iOS/macOS native dependencies via SwiftPM. Manually updating each one, regenerating lockfiles, and re-resolving Package.resolved eats hours and often breaks the build. You need a repeatable, verifiable process that does it all and leaves zero conflicts behind.

Why agents benefit

• Enforces a single workflow across all Dart packages and workspaces, eliminating missed or partial updates.
• Regenerates every lockfile (pubspec.lock, Package.resolved) to match new versions, keeping CI and local builds reproducible.
• Handles conflict resolution automatically, using the repo's structure to know which packages share a resolution and which are independent.
• Verifies changes with analyze, test, and codegen, so the agent's confidence is backed by real output, not guesswork.
• Keeps commit hygiene by separating dependency bumps from feature work and providing a clear changelog.

Practical scenarios

Monthly dependency hygiene sprint

You need to bump all Flutter packages across client and bridge modules before a release freeze. Run update-dependencies. The agent updates every pubspec.yaml, resolves each Dart workspace, regenerates lockfiles, and updates the iOS/macOS Package.resolved files. Then it runs the full test suite and codegen to confirm nothing broke.

Cross-platform native sync

A new version of a Swift package adds a breaking API change. The agent re-resolves Package.resolved across all iOS and macOS targets, updates Fastlane and Gemfile versions if needed, and then runs the Dart tests to catch integration issues early.

Onboarding a new developer

Your team grows. A new dev clones the repo and runs update-dependencies to get every dependency to the latest known-good state. The agent performs a clean update, regenerates lockfiles, and runs verification, leaving the dev with a consistent, working environment without manual step-by-step instructions.

Add it to your agent workflow

Install with:

npx skills add sesari-ai/sesari_apps_monorepo --skill update-dependencies

Then invoke it in your agent's context, e.g., "Run weekly dependency update" or "Bump all dependencies and verify." The skill reads the repo structure from the README, identifies the workspaces and standalone packages, and executes the full workflow. You can set a trigger on a weekly schedule or when a PR merges.

Compare before adopting

Consider quality signals: how often the skill's repository receives updates and whether it tracks recent Flutter/Swift changes. Compare it against alternatives like Dependabot or manual scripts. Check if its conflict-resolution logic matches your monorepo layout—it's built for Sesori's specific structure. Also weigh workflow fit: does your team already have a similar pattern? The skill shines when you need a single, opinionated process that covers both Dart and SwiftPM dependencies.

Why it is worth tracking

The skill comes from a team that actively maintains a large monorepo, so its updates reflect real-world pain points and fixes. With 105 stars and a focused README, it's likely to evolve with the ecosystem. Track it if you work with Flutter monorepos, especially those mixing Dart and native apps. Evaluate the source code for reuse in your own automation. As agents become more autonomous, having a tested, versioned skill like this reduces the chance of silent dependency drift.
