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.

v0.5.0 — 21 plugins: 1 core + 4 shared libs + 7 JS/TS stacks + 5 PHP/Laravel/Symfony stacks + 3 Java/.NET stacks. Cost-optimized: model tiering + effort per-subagent.

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

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

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

Key principles:

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

Stack Priority Table

Priority	Plugin	Aspects	Detect
0	vanilla (sdlc)	—	* (always matches)
100	nodejs-plugin	backend	package.json + express/fastify/koa/...
100	laravel-plugin	backend, database	composer.json + laravel/framework
100	symfony-plugin	backend, database	composer.json + symfony/framework-bundle
100	java-plugin	backend	pom.xml or build.gradle or build.gradle.kts
100	aspnet-core-plugin	backend, database	appsettings.json
150	react-plugin	frontend	package.json + react (without next, react-native)
150	vue-plugin	frontend	package.json + vue
150	spring-boot-plugin	backend	any build file + spring-boot marker
175	inertia-vue-plugin	frontend	package.json + @inertiajs/vue3
175	inertia-react-plugin	frontend	package.json + @inertiajs/react
200	nestjs-plugin	backend, database	package.json + @nestjs/core
200	angular-plugin	frontend	package.json + @angular/core
250	nextjs-plugin	backend, frontend	package.json + next
