Independent curation for practitioners building agentic AI systems. Conviction-rated. No paid placement, no affiliate links. A 2/5 here is honest; a 5/5 is something I use daily.

Skill
  • Claude Code The fastest path from intent to shipped code I've found. What makes it different from every other AI coding tool is agentic mode with real persistent context. It finishes tasks, not just suggests lines. If you're building in this ecosystem and aren't using it daily, you're leaving hours on the table. Non-negotiable.
    npm install -g @anthropic-ai/claude-code
  • LangChain High install count, heavy abstraction layer, and a habit of hiding the actual LLM call from you when you most need to see it. Good for getting a RAG prototype running in an afternoon. Not where I'd want to be when debugging a production agent at 2am. The patterns it encodes are worth understanding. The dependency itself, less so.
Tool
  • LiteLLM The cleanest way to route across Claude, GPT-4o, Gemini, and local models behind a single OpenAI-compatible endpoint. Saves you from hardcoding provider SDKs everywhere and makes switching models a config change, not a refactor. The proxy mode is where it really earns its place. Run it once, point all your agents at localhost.
    pip install litellm
  • Ollama The friendliest way to run local models. One command, no Python environment drama. Indispensable for offline experiments, cost-free eval loops, and keeping sensitive data off third-party APIs. Honest caveat though: local model quality still trails frontier models on complex reasoning, so treat it as a complement rather than a replacement.
    brew install ollama
MCP Server
  • Context7 MCP Solves the stale-docs problem that plagues AI coding assistants. Pulls live, version-accurate library documentation directly into Claude's context so you stop getting hallucinated API signatures. If your team ships against fast-moving SDKs like Astro, LangChain, or MCP itself, this is a quiet force multiplier.

Marketplace
  • Smithery The most useful MCP server directory right now. Good breadth, install snippets, and a growing catalog. Valuable as a starting point for discovery. Do your own due diligence before wiring any server to a production agent. Quality and maintenance levels vary significantly across listings.
