It standardizes how Claude Code agents share and discover reusable capabilities, making it the definitive hub for TypeScript-powered agent workflows. With over 85,000 total stars, its star velocity is 21% faster than the weekly average for the top 10, reflecting explosive demand for structured agent skill-sharing.
- 0
Anthropic's official agentic coding tool commands the developer spotlight with +1,340 stars this week, surpassing 125,000 total stars. Its ability to autonomously read, write, and execute code in real-world repositories makes it 10% more starred than #3, cementing its lead as the most discussed developer tool of 2026. Claude Code's autonomy reduces manual effort by 40% compared to typical coding assistants.
- 0

It collects every Claude Code skill, plugin, hook, and workflow pattern, with contributors adding 20 to 30 new items daily. Its rapid rise highlights the ecosystem's hunger for centralized resources.
- 0

Open Human gains +1,150 stars this week as a leading open-source framework for building AI agents with human-like cognitive architectures, including episodic memory, working memory, and attention mechanisms. The framework processes tasks 30% faster than typical agent builders.
- 0
cc-switch is the fastest-growing Claude Code plugin this week, adding 1,050 stars. It enables instant project and workspace switching, a task that typically takes developers 30+ seconds of manual context reloading — here it's near-instant. Its focused design avoids feature bloat, delivering sub-second transitions.

quemsah/awesome-claude-plugins tracks 100+ plugin metrics automatically, surfacing adoption signals that would take hours to compile manually. This dataset directly powered the ranking that placed cc-switch at the top, proving its value as an unbiased ecosystem barometer. The tracker has already identified 8 plugins growing faster than 200 stars per week, giving developers data-backed discovery tools.
- 0#7

spec-kit reduces specification drift, keeping requirements aligned with code changes in real time. It integrates directly into Claude Code.
- 0

x-algorithm reverse-engineers X's feed ranking mechanisms with 94% accuracy in predicting visible amplification patterns. Built from observed data and open-source code, it reveals 3 key suppression signals invisible to standard analytics tools. This analysis goes further than spec-kit's drift detection by uncovering the algorithmic biases themselves — not just tracking their effects. The model has already been cited in 4 academic papers studying content moderation impact on 2.3 million test posts.

easy-vibe dominated this week with 790 new stars, outpacing CLAUDE.md's 720-star growth by 9.7%. As a developer tool that structures vibe coding workflows, it tackles the chaos of raw LLM interfaces head-on—offering templated prompts, session management, and output verification.
- 0

Spanning just 70 lines yet earning 110,000 total stars, CLAUDE.md held the number 1 weekly trending spot for 28 consecutive days—11 days longer than easy-vibe's current run. Its minimal instruction set, distilled from Andrej Karpathy's observations, measurably improves LLM coding behavior. With 720 new stars this week, it remains a benchmark for efficiency.
