Two entries tackle review and security from opposite ends. cloudflare/security-audit-skill maps a codebase’s trust boundaries, sends isolated hunter agents after the gaps, then hands every candidate finding to a fresh verifier that tries to disprove it, so only issues with a complete source trace reach the report. alibaba/open-code-review is the everyday companion: it reviews a diff and places AI comments on the exact lines that need attention, with plain program logic placing each comment. Run the first before a release, the second on every pull request.
The busiest shelf this week is agent manners. mattpocock/skills makes an assistant ask detailed questions before writing code, DietrichGebert/ponytail tells it to reuse existing code instead of inventing a framework for every small fix, and ayghri/i-have-adhd rewrites replies so the answer comes first and each one ends with a concrete next step. addyosmani/agent-skills packages engineering routines with verification steps, and tamaratran/fast-jev-compaction keeps long sessions coherent by scoring each tool call keep-or-drop.
The heavy machinery is worth a look too. JustVugg/colibri streams the experts of giant mixture-of-experts models from disk, treating VRAM, RAM and storage as one memory hierarchy, so models in the hundreds of billions of parameters run on consumer hardware. hypit-ai/hypit gives coding agents a language for video: drop in a reference clip and the agent rebuilds it as a workflow timed to words, compiling captions and motion graphics without a generation model. Tencent/WeKnora turns scattered documents into a self-updating wiki with linked markdown and a knowledge graph.
For places to run agents, deepseek-ai/deepseek-harness is DeepSeek’s own plugin-based runtime with a web interface, still a developer preview, and stablyai/orca compares several terminal agents in separate Git worktrees so attempts can be judged side by side. Tencent/BrowserSkill lets an agent drive the browser you are already logged into, handing control back when a captcha appears. google/artemis does the same for a real Android phone over MCP. And NationalSecurityAgency/ghidra needs no introduction to reverse engineers, but if you have never decompiled a binary, this is the week to see what the NSA’s open framework can read.
Smaller finds worth an evening: bojieli/ai-infra-book derives LLM system design from hardware limits in a Chinese manuscript, deeplethe/utopia traces AI answers to sources and timelines, abue-ammar/tinycast is a native macOS launcher under 100 MB that runs your Raycast extensions, latent-spaces/brag packages a finished project into a launch video, debpalash/VoiceStudio tries voice design and dubbing locally, and eternity4719/HowToLiveBetter or bilawalsidhu/gods-eye-view reward a break.
