highlevel.md Below is a lean-but-impressive “GemHub” platform plan that layers on top of Continue.dev yet stays hack-friendly. Every box uses well-known, minimal libraries that play nicely together (Ruby 3.3 ± RBS, Node 20, Python 3.11; all services run under one docker-compose.yml).

All arrows crossing language boundaries are simple JSON/HTTP to avoid incompatibility headaches.

2 ▸ Minimal-Lib Component Choices
Concern Lib / Runtime Why it’s the simplest that works API & Registry Sinatra (Ruby) + sequel ORM → SQLite One-file Ruby micro-API; no Rails weight. Sandbox docker-compose + plain bash scripts No K8s; deterministic across OS. Benchmarks benchmark-ips, mutant, simplecov (Ruby gems) Already used in Ruby OSS projects; zero extra daemons. Vector Store FAISS + sqlite3 (Python) Fast local search; trivial Docker image. LLM Gateway FastAPI (Python) Async, three-file server; avoids Node deps in gateway. Front-End Continue.dev React panel (already provided), plus D3.js for charts No separate SPA build pipeline. CLI Thor (Ruby) Ships with GemHub for devs outside VS Code.

3 ▸ Hackathon-Scale Technical Roadmap
Phase Hrs Deliverable Key Tasks & Libs 0. Repo & Infra 1 Monorepo scaffold + docker-compose.yml Create services/ skeleton, pin Ruby 3.3, Node 20, Python 3.11 images.
- Core Marketplace 3 Sinatra API + SQLite + Continue sidebar “Marketplace” tab CRUD routes (/gems, /ratings), list & star gems.
- Wizard & CLI 2 gemhub-wizard (React flow) + gemhub Thor CLI Prompt name/license, call existing GemCrafter commands.
- Sandbox Launch 2 One-click Docker sandbox Bash script generates docker-compose.sandbox.yml, mounts gem, boots Rails demo.
- Bench + CVE Scan 3 Benchmark & Security tabs Run benchmark-ips vs. competitors; fetch RubySec JSON; display charts via D3.
- LLM Integrations 2 Claude-powered Rank + Roadmap FastAPI wrapper; anthropic client; call for “Top trending” & feature suggestions.
- Polish & Gamify 1 Badges, leaderboard mock data Compute badges in API; render trophy icons in sidebar.
- Demo Script 1 60-s flow: wizard ▸ sandbox ▸ benchmark ▸ publish Record GIF, prep pitch.
Total: 14 productive hours → fits a one-day or two-evening hack sprint.

How to Run (developer machine)
git clone https://github.com/jadenfix/ruby && cd gemhub docker compose up -d # boots API, FAISS, LLM gateway npm run dev --workspace extension # hot-reload VS Code panel bin/gemhub wizard # same flow via CLI

Compatibility Checklist ✔︎
Layer Language Container? Notes VS Code ext TS/React n/a Uses Continue.dev APIs only. API & CLI Ruby 3.3 yes Same gemset, avoids native ext gems. AI & Embeddings Python 3.11 yes faiss-cpu, anthropic. Front visuals React + D3.js n/a Bundled by esbuild. Orchestration Docker Compose v2 yes Works Mac/Windows/Linux.
Stick to these rails-light libraries and you’ll demo a massive feature set without wrestling heavy dependencies—perfect for hack-day velocity and long-term maintainability.
