01 THE IDEA

Last 30 Days is a Model Context Protocol (MCP) skill for Claude Code that aggregates real-time social and web signals — specifically from X/Twitter (via xAI API), Reddit (via OpenAI's Reddit deal), and general web search — and feeds them as grounded context into Claude Code prompts. Instead of relying on LLM training data that may be months old, users type /last30days followed by any topic and get a synthesized brief on what the internet is actually saying right now, which then powers dramatically better outputs for coding, copywriting, design, and strategy tasks.

The core insight is that Claude Code's biggest limitation is stale knowledge; the best prompts are built on current community wisdom. By wiring live social data into the prompt pipeline, the tool effectively lets any Claude Code user 'download expertise' on any fast-moving topic — new AI tools, cold email frameworks, trending design aesthetics, competitor analysis — before executing a build or writing task. The product is early, built by a non-engineer founder through pure vibe-coding, and already gaining organic traction in the Claude Code power-user community.

03 THE VERDICT

This is a textbook early-ecosystem land-grab: Claude Code is exploding in adoption, the MCP plugin layer is nascent with almost no established players, and the product has already demonstrated organic traction with minimal effort. The multi-API data moat (xAI + Reddit + web) is genuinely hard to replicate casually, and the use case — grounding AI prompts in live community wisdom — is universally applicable across every Claude Code user's workflow. The main risk is Anthropic shipping this natively, but that's a 'acqui-hire or get copied by the platform' problem, which is still a good outcome.

Verdict: BUILD. Don't have the ~80 hours it takes? Get matched with a vetted builder who does — we review every brief by hand and intro you to up to 3 builders.
