Claude-skills weekly: academic-research and scientific-agent bundles jumping, opcode looks abandoned, one sleeper for NotebookLM users
I run a tracker that snapshots a few thousand AI/ML repos daily — stars, commits, releases. Pulled the May 10 → May 17 window for Claude-skill / Claude-Code repos. Two bundles broke out, one once-popular GUI looks abandoned, and one sleeper most people haven't seen.
**K-Dense-AI/scientific-agent-skills: +2,664 stars in 7 days (+12.9%)**
20,680 → 23,344. A ready-to-use Agent Skills bundle for research, science, engineering, analysis, finance and writing. Last commit May 18. This is the kind of pre-baked skill pack that gets traction with users who don't want to author skills from scratch. Worth a fork before customizing for your own domain.

**Imbad0202/academic-research-skills: +2,417 stars in 7 days (+39.7%)**
6,084 → 8,501. A narrower, sharper play than the K-Dense bundle. Workflow is research → write → review → revise → finalize, all as Claude Code skills. The +40% week is the kind of breakout that usually means it landed in a popular dev's video or thread; the value is the workflow shape, not any single skill.

**winfunc/opcode: looking abandoned**
21,816 stars, only +43 over 7 days, and **216 days since the last commit**. opcode was a popular GUI for Claude Code — custom agents, interactive sessions, background agents. The stars from the original hype are still there but new growth has flattened and there's been no maintenance in 7 months. If you depend on it for a workflow, worth either forking or moving to an actively-maintained alternative. Same pattern shows on `Maciek-roboblog/Claude-Code-Usage-Monitor` (7,991 stars, last commit 301 days ago).
**Sleeper: joeseesun/qiaomu-anything-to-notebooklm: +1,763 stars (+109%), still under 3.5k**
1,614 → 3,377. Claude Skill that takes WeChat articles, web pages, YouTube, PDF, Markdown or search queries and turns them into NotebookLM-ready inputs — also produces podcast / PPT / mindmap / quiz outputs. Useful niche: people using NotebookLM as a research workspace but tired of manually feeding it sources. Last commit Apr 28 (3 weeks ago) so still under active maintenance.

Data: daily GitHub snapshots, 7-day windows compared to the most recent snapshot at least 7 days prior. Tracker I run at beamforai.com — drop a Claude skill or Claude Code repo in the replies and I'll pull a 30 or 90-day curve.
