name: ln-710-dependency-upgrader description: Coordinates dependency upgrades across all detected package managers
ln-710-dependency-upgrader
Type: L2 Domain Coordinator Category: 7XX Project Bootstrap Parent: ln-700-project-bootstrap
Coordinates dependency upgrades by detecting package managers and delegating to appropriate L3 workers.
Overview
| Aspect | Details |
|---|---|
| Input | Detected stack from ln-700 |
| Output | All dependencies upgraded to latest compatible versions |
| Workers | ln-711 (npm), ln-712 (nuget), ln-713 (pip) |
Workflow
See diagram.html for visual workflow.
Phases: Pre-flight → Detect → Security Audit → Delegate → Collect → Verify → Report
Phase 0: Pre-flight Checks
Verify project state before starting upgrade.
| Check | Method | Block if |
|---|---|---|
| Uncommitted changes | git status --porcelain | Non-empty output |
| Create backup branch | git checkout -b upgrade-backup-{timestamp} | Failure |
| Lock file exists | Check for lock file | Missing (warn only) |
Skip upgrade if uncommitted changes exist. User must commit or stash first.
Phase 1: Detect Package Managers
Detection Rules
| Package Manager | Indicator Files | Worker |
|---|---|---|
| npm | package.json + package-lock.json | ln-711 |
| yarn | package.json + yarn.lock | ln-711 |
| pnpm | package.json + pnpm-lock.yaml | ln-711 |
| nuget | *.csproj files | ln-712 |
| pip | requirements.txt | ln-713 |
| poetry | pyproject.toml + poetry.lock | ln-713 |
| pipenv | Pipfile + Pipfile.lock | ln-713 |
Phase 2: Security Audit (Pre-flight)
Security Checks
| Package Manager | Command | Block Upgrade |
|---|---|---|
| npm | npm audit --audit-level=high | Critical only |
| pip | pip-audit --json | Critical only |
| nuget | dotnet list package --vulnerable | Critical only |
Release Age Check
| Option | Default | Description |
|---|---|---|
| minimumReleaseAge | 14 days | Skip packages released < 14 days ago |
| ignoreReleaseAge | false | Override for urgent security patches |
Per Renovate best practices: waiting 14 days gives registries time to pull malicious packages.
Phase 3: Delegate to Workers
Delegation Context
Each worker receives standardized context:
| Field | Type | Description |
|---|---|---|
| projectPath | string | Absolute path to project |
| packageManager | enum | npm, yarn, pnpm, nuget, pip, poetry, pipenv |
| options.upgradeType | enum | major, minor, patch |
| options.allowBreaking | bool | Allow breaking changes |
| options.testAfterUpgrade | bool | Run tests after upgrade |
Worker Selection
| Package Manager | Worker | Notes |
|---|---|---|
| npm, yarn, pnpm | ln-711-npm-upgrader | Handles all Node.js |
| nuget | ln-712-nuget-upgrader | Handles .NET projects |
| pip, poetry, pipenv | ln-713-pip-upgrader | Handles all Python |
Phase 4: Collect Results
Result Schema
| Field | Type | Description |
|---|---|---|
| status | enum | success, partial, failed |
| upgrades[] | array | List of upgraded packages |
| upgrades[].package | string | Package name |
| upgrades[].from | string | Previous version |
| upgrades[].to | string | New version |
| upgrades[].breaking | bool | Is breaking change |
| warnings[] | array | Non-blocking warnings |
| errors[] | array | Blocking errors |
Phase 5: Verify Build
Build Commands by Stack
| Stack | Command |
|---|---|
| Node.js | npm run build or yarn build |
| .NET | dotnet build --configuration Release |
| Python | pytest or python -m pytest |
On Build Failure
- Identify failing package from error
- Search Context7/Ref for migration guide
- Apply known fixes
- If still fails: rollback package, log warning
Phase 6: Report Summary
Report Schema
| Field | Type | Description |
|---|---|---|
| totalPackages | int | Total packages analyzed |
| upgraded | int | Successfully upgraded |
| skipped | int | Already latest |
| failed | int | Rolled back |
| breakingChanges | int | Major version upgrades |
| buildVerified | bool | Build passed after upgrade |
| duration | string | Total time |
Configuration
Options:
# Upgrade scope
upgradeType: major # major | minor | patch
# Breaking changes
allowBreaking: true
autoMigrate: true # Apply known migrations
# Security
auditLevel: high # none | low | moderate | high | critical
minimumReleaseAge: 14 # days, 0 to disable
blockOnVulnerability: true
# Scope
skipDev: false # Include devDependencies
skipOptional: true # Skip optional deps
# Verification
testAfterUpgrade: true
buildAfterUpgrade: true
# Rollback
rollbackOnFailure: true
Error Handling
Recoverable Errors
| Error | Recovery |
|---|---|
| Peer dependency conflict | Try --legacy-peer-deps |
| Build failure | Rollback package, continue |
| Network timeout | Retry 3 times |
Fatal Errors
| Error | Action |
|---|---|
| No package managers found | Skip this step |
| All builds fail | Report to parent, suggest manual review |
