61.9k stars (Global Rank #271) — drop one of 55+ DESIGN.md files from Stripe, Linear, Notion, Figma, or ElevenLabs into your project root and Claude Code generates a pixel-perfect matching UI automatically. Launched March 31, accumulated 4,385 stars in its first three days. Covers color palettes, typography hierarchies, component states, elevation systems, and design guardrails — all in plain markdown that LLMs understand natively.

73.6k stars — Y Combinator CEO Garry Tan open-sourced his Claude Code setup as a 23-skill virtual dev team: a CEO who rethinks product direction, a Designer who catches AI slop, an Eng Manager who locks architecture, a QA Lead who opens a real browser, and a Security Officer who runs OWASP + STRIDE audits. April 2026 update added Team mode (`./setup --team`) and multi-host support for Codex, Cursor, OpenCode, Kiro, and Factory Droid. Issues filed April 21 — active.

Released April 22 (today): effort default bumped to `high` for Pro/Max on Opus 4.6 and Sonnet 4.6, forked subagents enabled on external builds via `CLAUDE_CODE_FORK_SUBAGENT=1`, `/model` selections now persist across restarts, and `/resume` offers to summarize stale large sessions before re-reading. Native builds replace Glob and Grep with embedded `bfs` and `ugrep` for faster file search. Plugin dependency auto-resolution lands — `blockedMarketplaces` and `strictKnownMarketplaces` in managed-settings enforce install policy org-wide.
Research preview (April 14): save a Claude Code configuration once — prompt, repo, connectors — and have it run automatically on Anthropic-managed cloud even when your laptop is closed. Three trigger types: Scheduled (hourly/nightly/weekly), API (HTTP POST to a per-routine endpoint with bearer token), and GitHub (fires on PR open, push, or release). IndyDevDan dedicated a full video to it — "Claude Routines Just Dropped, And It's Perfect." Available on Pro, Max, Team, and Enterprise.

821 stars — inspired by Andrej Karpathy's LLM Knowledge Base architecture: a SessionEnd hook captures every conversation, the Claude Agent SDK extracts key decisions and lessons, then an LLM compiler organizes them into structured, cross-referenced knowledge articles injected back via SessionStart. Launched April 6; gained 237 stars in its first day. Unlike claude-mem (flat session replay), this compiles a growing wiki that improves with every session.
Self-correcting memory that compounds over 50+ sessions: when you correct Claude, it proposes a rule, you approve it, it's saved to SQLite, and by session 2 it writes correctly without reminders. v2.0 ships 18 hook events, 5 agents, 7 reference guides, 17 battle-tested skills, and an 80/20 AI coding ratio guide. Context engineering, parallel worktrees, and wrap-up rituals included. Works across Claude Code, Cursor, Codex, Kiro, Goose, Roo, and 27 more tools.
17.8k stars — 100+ specialized Claude Code subagent definitions from VoltAgent covering core-development, quality-security, infrastructure, data-ai, and business-product use cases. Each agent ships with a focused system prompt, tool allowlist, and examples. A companion to VoltAgent/awesome-agent-skills (already in the digest), this collection targets the subagent coordination layer specifically.
A slash command that turns Claude into a Tech Lead orchestrating parallel Worker Agents: PRD alignment → architecture → isolated git worktree Workers → QA verification → structured code review with veto conditions → merge. Each Worker does a 6-category counterexample self-check before finishing; mandatory security audits (bandit / npm audit) run before the review phase. MIT licensed. 89 Product Hunt points at launch.
219 stars — curated DESIGN.md prompts organized by aesthetic family (warm, terminal, editorial, glass, brutalist, cinematic, indie) with remix recipes (e.g. Linear × Claude) and launch-week community signal. Launched to accompany Claude Design (April 17). Pairs with five Claude Code skills — design-shotgun, design-html, design-review, design-consultation — installable via SkillKit.
"Why use many token when few token do trick" — 39.7k stars. Cuts ~65–75% output tokens and ~46% input tokens while preserving technical accuracy. One-line install for Claude Code, Cursor, Windsurf, Copilot, and more. Arjan Brussee's LinkedIn post still circulating; community discussion active across r/ClaudeCode.

162k stars — 48 agents, 183 skills, 34 language rules, 14+ MCP configs. v1.10.0 (April 2026) added a desktop dashboard GUI and launched the ECC 2.0 alpha — the community calls it the 'Claude Code distro'. ECC 2.0 alpha discussion remains active on Reddit.
