name: update-dependencies description: "Upgrade project dependencies with breaking change research for major version updates. Use when the user asks to "update dependencies", "upgrade packages", "upgrade dependencies", "update deps", "upgrade deps", "update npm deps", "update Swift packages", "cargo update", "go get updates", "bundle update", or "pip upgrade"."
Update Dependencies
Upgrade project dependencies, researching breaking changes for major version updates.
Optional filter: $ARGUMENTS (e.g., react, Alamofire, serde tokio)
Phase 1: Review Dependencies
Run the $review-dependencies skill to detect package managers and discover available updates. If no updates are available, stop.
Phase 2: User Strategy Selection
Present a summary showing:
- Count and list of major updates (with current → target versions)
- Count of minor updates
- Count of patch updates
Use request_user_input for upgrade strategy (Codex request_user_input allows up to 3 options per question, so the four strategies are split across two questions):
Question 1 — Header: "Approach" Options:
- Cautious — Upgrade minor/patch first, then major one-by-one with research
- All at once — Research all major changes, then upgrade everything together
- Major handling — Defer the major decision (Skip-major or Interactive)
If the user picks Major handling, ask a follow-up:
Question 2 — Header: "Major handling" Options:
- Skip major — Only upgrade minor and patch versions
- Interactive — Ask for each major update individually
- Cancel — Cancel and return to the previous step
Phase 3: Research Breaking Changes
For each package with a major version update:
Step 1: Calculate Version Gap
Identify all major versions between current and target. For example:
react: 17.0.2 → 19.0.0→ research v18 AND v19 breaking changesAlamofire: 4.9.1 → 6.0.0→ research v5 AND v6 breaking changes
Step 2: Research Each Major Version
Search for migration documentation:
Web search: "[package-name] v[X] migration guide"
Web search: "[package-name] v[X] breaking changes"
Common sources: GitHub releases page, official docs, changelog files.
Step 3: Extract Key Breaking Changes
Identify: API changes (renamed/removed functions), configuration changes, peer/transitive dependency requirements, behavioral changes, deprecated features now removed.
Step 4: Search Codebase for Affected Code
Use rg to find usage of deprecated or changed APIs. Document which files are affected and what changes are needed.
Phase 4: User Confirmation
For each major update, present:
- Package name and version transition
- Breaking changes found (summarized)
- Files potentially affected (count and list)
Use request_user_input to confirm (Codex request_user_input allows up to 3 options per question, so the four actions are split across two questions):
Question 1 — Header: "Decision" Options:
- Proceed — Continue with upgrades and migrations
- Show details — Display detailed breaking changes for review
- Other action — Defer the choice (Skip-package or Abort)
If the user picks Other action, ask a follow-up:
Question 2 — Header: "Other action" Options:
- Skip package — Exclude a specific package from upgrade
- Abort — Cancel the upgrade process
- Cancel — Cancel and return to the previous step
If "Show details" selected, display full migration research, then ask again.
Phase 5: Execute Upgrades
Cautious Strategy
First upgrade minor and patch only using the package manager's semver-respecting update command, then run tests. If tests fail, stop before proceeding with major upgrades.
Major Version Upgrades
Update the manifest file (version constraint) and run the install/resolve command. For package managers with a dedicated upgrade command, use it. For others (Swift PM, Maven, Gradle), edit the manifest directly.
Phase 6: Apply Migrations
Step 1: Run Codemods (if Available)
Some ecosystems provide automated migration tools:
| Ecosystem | Migration tools |
|---|---|
| React | npx react-codemod [transform] |
| Next.js | npx @next/codemod [transform] |
| Jest | npx jest-codemods |
| Angular | npx ng update |
| Rust | cargo fix for edition migrations |
| Python | pyupgrade, python-modernize |
Step 2: Manual Code Changes
For changes requiring manual intervention:
- Read the affected file
- Apply the necessary transformation with
apply_patch - Show the user what changed
Step 3: Update Configuration Files
If configuration format changed, read current config, transform to new format, write updated config.
Step 4: Sync Version-Pinned CI/Container References
Some packages pin their version outside the manifest, beyond the package manager's reach, so a green local run hides the drift. For every upgraded package (major, minor, or patch), search CI and container configs for the old version string with rg "<old-version>" .github Dockerfile* docker-compose* .devcontainer and bump it in lockstep:
- CI container images whose tag must track the package — e.g. a Playwright image tag kept in lockstep with the installed
@playwright/testversion. - Base images and tool versions in
Dockerfile,.devcontainer/, anddocker-compose.yml. - Pinned tool versions in CI setup steps (
actions/setup-nodenode-version,setup-python, toolchain files).
Phase 7: Verification
Run the project's test, build, and lint commands. Detect which commands are available from the project's config files and scripts. Use project-level task runners when present (Makefile, Taskfile, justfile, npm scripts, etc.).
Report Results
Summarize: packages upgraded (count), breaking changes addressed (count), files modified (count), test results, remaining manual tasks.
Recommend Next Steps
If any migrations could not be automated:
- List specific changes the user needs to review
- Highlight deprecated patterns that need attention
- Note any runtime behavior changes to watch for
Error Handling
Discovery Tool Not Available
If the discovery tool is not installed, $review-dependencies will note it. Fall back to manual version checking via web search.
Network Errors During Research
If web search/fetch fails: retry with alternative search terms, provide manual research links, proceed with caution warning that migration research may be incomplete.
Test Failures After Upgrade
- Stop the upgrade process
- Suggest rollback: restore manifest and lockfile from git, then reinstall
- Identify which package likely caused the failure
Migration Research Incomplete
If official migration docs are not found: check the package's repository for issues and discussions, note as "migration research incomplete — proceed with caution."
