last30days Skill — Setup Guide

Source: mvanhorn/last30days-skill GitHub: mvanhorn/last30days-skill Skills: 3 skills · 32.7K total installs (core skill carries 32.7K) Category: Research & Discovery First Seen: catalogued August 17, 2026 sweep (last30days on skills.sh since February 7, 2026) Quality Tier: 🟡 Trusted — Gen Agent Trust Hub Fail and Snyk Fail named (see Limitations)

last30days is a research skill for finding what actually happened recently: projects, repos, and ecosystem activity with movement in the last 30 days. Its opening move is a stale-clone self-check, then it runs structured searches and synthesizes a fresh-activity report — the pattern behind "what's new in X right now" questions.

Installation

npx skills add mvanhorn/last30days-skill

Individual skills install with the explicit repo form:

npx skills add https://github.com/mvanhorn/last30days-skill --skill last30days

Prerequisites

Requirement Details
Search access Web/GitHub search for activity lookups
Skill hygiene The skill's own stale-clone self-check verifies it was not loaded from an outdated marketplace cache

What It Provides

Skill Installs Purpose
last30days 32.7K Core research workflow: 30-day-window activity discovery
last30days-3 2 Companion variant
last30days-v3-spec 1 v3 specification notes

Quick Start

  1. Install: npx skills add mvanhorn/last30days-skill
  2. Ask: "what's new in in the last 30 days"
  3. The skill runs recency-windowed searches and reports fresh projects and activity

CorpusIQ Use Cases

Use Case How
Ecosystem discovery A recency window pairs with our nightly ecosystem scans — fresh-activity bias for skills.sh and MCP directory sweeps
Competitive research "What shipped in in the last 30 days" as a first-pass brief
Catch-up briefings Fast context rebuild after downtime or focus elsewhere

Limitations / Verification

  • Security audits on last30days: Gen Agent Trust Hub Fail, Socket Warn, Snyk Fail — the two Fails are named here per catalog policy; review the findings before production use
  • Publisher-page install counts verified (32.7K core); GitHub 58.4K stars on the repo — the star count and install base are large, but the audit fails mean the skill's dependencies deserve a closer look in security-sensitive contexts
  • Companion skills (last30days-3, last30days-v3-spec) are sub-10 installs — effectively single-skill content
npx skills add mvanhorn/last30days-skill   # verify install works
