About

What it does

DoubleslashSE’s Claude marketplace is a seven-plugin bundle aimed at builders who want Claude Code to behave more like a staffed pod—brainstorming before commits, TDD discipline, targeted stack help, and infra awareness—without maintaining separate prompt libraries. Keywords surface Node and TypeScript flows, a .NET ecosystem plugin, Postgres and Supabase data work, Railway hosting, proactive troubleshooting, and a simplified meta-orchestrator that routes tasks by capability instead of one giant system prompt. Workshop and stakeholder-interview style commands support requirement clarity before implementation, while validation and static-health motifs push quality before you ship. Because plugins are heterogeneous, treat the bundle as a multi-phase toolkit: use ideation and scoping commands early, stack builders during implementation, and monitoring or error-resolution plugins when operating. Confidence is moderate where per-plugin SKILL.md detail is thin in the ingest snippet; install individual plugins and read each manifest before relying on gates in production.

Highlights

  • Seven-plugin marketplace spanning brainstorming, test-driven development, and stack-focused Node/TypeScript and .NET wor
  • Infrastructure and data plugins aligned with Postgres, Supabase, and Railway deployment patterns
  • Meta-orchestrator-style routing and continuation patterns for exploring uncharted codebase territory
  • Stakeholder workshop and requirements-gathering facilitation commands for early alignment
  • Error diagnosis, static analysis, and quality gates with YAGI/SOLID-oriented clean-code emphasis

Why builders use it

You hop between disconnected Claude prompts for brainstorming, tests, Supabase, and deploy fixes instead of a consistent plugin set tuned to your stack.

After registering the marketplace, you enable stack- and phase-specific plugins so Claude Code can route work from requirements through implementation and troubleshooting with shared DoubleslashSE patterns.
