- NEW: Polyglot workspaces — Native support for Gradle, Maven, .NET alongside JS/TS projects
## Best Practices
- Use domain-based folder structure — Group projects by business domain
```
libs/
├── auth/
│ ├── feature-login/
│ └── data-access/
├── products/
│ ├── feature-list/
│ └── ui/
└── shared/
├── ui/
└── utils/
```
- Use Nx generators — Scaffold consistent code across workspace
```bash
# Create new library
nx g @nx/angular:library --name=shared-data-access --directory=libs/shared/data-access
# Create new feature
nx g @nx/angular:component --name=user-profile --project=my-app
```
- Use affected commands — Only run tasks on changed projects
```bash
nx affected:build # Build only changed projects
nx affected:test # Test only changed projects
nx affected:lint # Lint only changed projects
```
- Use shared libraries — Avoid code duplication with common utilities
- Configure task dependencies — Define how tasks depend on each other in `project.json`
```json
{
"build": {
"dependsOn": ["^build"]
}
}
```
- Use Nx Cloud — Enable distributed caching for faster CI
- Use `nx.json` and `tsconfig.base.json` — Enforce consistent settings across projects
- Use `@nx/angular:component` generator — Follow workspace conventions for components

relationship-science-coach
IncludedUse this skill for direct, practical adult relationship coaching: couples conflict, repair, trust, marriage, dating, flirting, attachment patterns, emotional connection, sex, desire differences, eroticism, kink negotiation, affection, love languages, breakups, and long-term passion. Draw on Gottman, EFT and Hold Me Tight, attachment science, modern sex research, Perel, Nagoski, Kerner, Schnarch, Love and Stosny, and flexible love-language tools. Be concrete and low-hedge. Redirect only for imminent danger, abuse, coercive control, minors, non-consent, self-harm, stalking, or medical/legal/psychiatric decisions.

IncludedSalesforce integration architecture and runtime plumbing with 120-point scoring. Use this skill to set up Named Credentials, External Credentials, External Services, REST/SOAP callout patterns, Platform Events, and Change Data Capture. TRIGGER when: user sets up Named Credentials, External Services, REST/SOAP callouts, Platform Events, CDC, or touches .namedCredential-meta.xml files.

venue-templates
IncludedAccess comprehensive LaTeX templates, formatting requirements, and submission guidelines for major scientific publication venues (Nature, Science, PLOS, IEEE, ACM), academic conferences (NeurIPS, ICML, CVPR, CHI), research posters, and grant proposals (NSF, NIH, DOE, DARPA). This skill should be used when preparing manuscripts for journal submission, conference papers, research posters, or grant proposals and need venue-specific formatting requirements and templates.
let-fate-decide
IncludedDraws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
