angular-plugin

Angular 18-21 SPA frontend stack provider for SDLC marketplace. Standalone components + NgModule equally, signals + services + NgRx (Store/Component Store/Signals), Reactive Forms (typed), Angular Router with functional guards, TestBed + component harnesses + Angular Testing Library. Modern era (signal-first, control flow @if/@for/@switch) with legacy NgModule fallback. Angular Universal (SSR) pointer-only — SPA focus.

SDLC Marketplace for Claude Code

Multi-stack AI-assisted SDLC pipelines built on the Stack Provider Pattern: a single core orchestrator runs the pipeline, framework plugins register themselves via declarative stack.md profiles. No core overrides, no slot registries, no copy-paste between stacks.

v1.2.0 — 26 plugins: 1 core + 5 shared libs + 7 JS/TS stacks + 5 PHP/Laravel/Symfony stacks + 3 Java/.NET stacks + 5 Python stacks. Cost-optimized: model tiering + effort per-subagent, fixed Haiku enforcement for the docs phase, file-scoped format hooks, shared architect conventions (~1,600 lines of boilerplate deduped), per-aspect QA fan-out on full-stack runs.

Quickstart

# 1. Add the marketplace
/plugin marketplace add AratKruglik/claude-sdlc

# 2. Install the stack plugin you need (sdlc core is installed automatically as a dependency)
/plugin install laravel-plugin@sdlc-marketplace
# or for JS/TS projects:
/plugin install nodejs-plugin@sdlc-marketplace   # Express/Fastify/Koa
/plugin install nestjs-plugin@sdlc-marketplace   # NestJS
/plugin install nextjs-plugin@sdlc-marketplace   # Next.js (full-stack)
/plugin install react-plugin@sdlc-marketplace    # React SPA
/plugin install vue-plugin@sdlc-marketplace      # Vue 3 SPA
/plugin install angular-plugin@sdlc-marketplace  # Angular 18-21
/plugin install react-native-plugin@sdlc-marketplace  # React Native / Expo
# or for Python projects:
/plugin install django-plugin@sdlc-marketplace   # Django + DRF
/plugin install fastapi-plugin@sdlc-marketplace  # FastAPI + SQLAlchemy 2.0
/plugin install flask-plugin@sdlc-marketplace    # Flask + Flask-Migrate
/plugin install python-plugin@sdlc-marketplace   # Plain Python (CLI/library/scripts)

# 3. Install optional plugins
/plugin marketplace add mattpocock/skills
/plugin install mattpocock-skills@skills # Enhances BA phase with interactive grilling

# 4. Verify
/sdlc:doctor
/sdlc:list-stacks

# 4. Run
/sdlc:start "Add subscription billing with Stripe"

Key principles:

Core never changes. Pipeline logic lives exclusively in pipeline-orchestrator/SKILL.md.
Plugins register themselves via stack.md frontmatter — they declare auto-detection rules, priority, agents per phase, and convention skills.
Per-aspect dispatch. A project can have multiple aspects (backend + frontend + database). Each aspect gets its own specialist.
Priority wins. When multiple profiles match, the highest priority takes over.

How Stack Selection Works

When /sdlc:start runs, the orchestrator needs to decide which agent handles development. The priority system is how it picks.

Each plugin has a stack.md file where it describes itself: "I handle projects that have X, and my priority is Y." The orchestrator scans all installed plugins, runs their detection rules against the current project, and picks the highest-priority match.

Step by step:

Scan ~/.claude/plugins/cache/**/stack.md — collect all registered profiles.
Each profile checks its detect rules: is there a package.json? Does it contain react? Is there a manage.py? And so on.
From those that matched — the profile with the highest priority number wins.
