5. New Blog Posts (24h)

None of today's tracked blogs (Lilian Weng, Anthropic Engineering, Cognition, Manus, Baoyu, Qwen, Jiqizhixin) published within the past 24 hours. Cognition and Anthropic Engineering last updated on Sept 22; Baoyu's latest is early-September's "I made a 3D 'Peach Blossom Spring' with GPT 6 Astra". HuggingFace Blog timed out twice on fetch today (HTTP 000) — reported honestly as unavailable.

6. GitHub New Projects (last 3 days, by stars, spam manually filtered)

Repo	⭐	Language	What it does
mikehasa/golive-skill	845	TS	Take your agent-built product live — hosting, database, domain, email, payments — on your own account
yetone/magpie	595	Go	Menu-bar aggregator for coding agents: run Codex on DeepSeek, Claude Code on Kimi
anishfn/shapeshift	566	TS	An input that becomes what you mean: one text box morphing into the right UI as you type
samyost1/3dicon	379	Python	One prompt in, a looping animated 3D icon with real transparency out — packaged as a Claude Code skill
saragordic/rooms	265	Swift	Mac project switcher: every project is a "room" of windows, restored with one shortcut

Filtering note: 10 of 15 candidates were removed — star-farmed no-description repos (claude-opus-5-5-demo, CLM), suspicious SEO projects (knoweldge-base), an apparent "Jev" mutual-star matrix (awesome-jev, Astra-Ares), and entertainment/demo repos (a Claude-generated music video, a demo coastal town, a lyrics-PV generator, a Minecraft utility client, a poorly documented network node).

7. GitHub Watch (ShuJieTai AI Video Watch board, tasks created in last 24h)

• [Watch] huggingface/diffusers (09-24 20:22): diffusers PR #14842 (9/24) looks like a '[docs] Adapters' docs PR but actually ships a full .ai/ agent plugin infrastructure (plugin.json, agent-plugins.org schema 1.0.0) — evaluating its plugin distribution model as inspiration for repackaging the magicedit Copilot skill.
• [Watch] openai/openai-agents-python (09-24 20:22): PR #5146 (9/23) fix(sandbox): check sandbox apply_patch approval scope — adopting the per-call-scope approval isolation fix to tighten magicedit's file-edit approvals.
• The other 3 board tasks (browser-use/jev-ultrafast, hypit-ai/hypit, langchain-ai/langgraph) were created earlier and are not within the 24h window.

8. arXiv cs.AI (Sept 23 batch, latest available)

• StudentBench: AI tutoring matches human tutoring on GRE learning gains — an empirical benchmark of AI augmenting human capability.
• Can LLMs Reason About Runtime Behavior?: a repository-level dynamic benchmark evaluating execution-time reasoning beyond static code understanding.
• Agent-Editing World Model: rethinking world modeling for LLM agents on long-horizon tasks.
• Order-Invariant Answers, Order-Sensitive Representations: rule order doesn't change math answers but does shape internal representations.
• Where Should I Join?: language-guided goal prediction for robot group joining (social navigation).
• Frozen Flows Forget: diagnosing and restoring lost motion in latent-flow world models.

Note: no new submission batch today (Friday); the above is the latest Thursday (9/23) batch, slightly outside the strict 24h window per standing convention.
