Hottest Repos
usestrix/strix — AI pentesting agents that find and validate real vulnerabilities with working PoCs. +8,370 this week (40k total). New to digest. Not another static scanner — these agents do recon, exploitation, and validation autonomously, with CI/CD integration to block vulns in PRs. Multi-agent orchestration, auto-fix, compliance reports. Apache-2.0. The "shift left" movement just got AI teeth. https://github.com/usestrix/strix
mattpocock/skills — The original Claude Code skills repo. +1,663 today (164.4k total). Still the single biggest daily gainer by absolute stars. The flywheel is self-sustaining — every new Claude Code user discovers it. https://github.com/mattpocock/skills
iOfficeAI/OfficeCLI — Office suite purpose-built for AI agents: Word/Excel/PowerPoint from a single binary. +1,210 today (14.3k total, +4,872 this week). Day 3 in digest. Crossed 14k — the growth is accelerating, not fading. Agents couldn't touch Office docs before; now they can. https://github.com/iOfficeAI/OfficeCLI
addyosmani/agent-skills — Addy Osmani's production-grade engineering skills. +1,114 today (76.7k total). Day 5+ in digest. Approaching 77k with no sign of slowdown. The celebrity-curator model remains the most efficient distribution channel for agent skills. https://github.com/addyosmani/agent-skills
openai/codex-plugin-cc — Use Codex directly from Claude Code to review code or delegate tasks. +4,792 this week (27.4k total). New to digest. OpenAI building a first-party bridge INTO a competitor's tool. The cross-pollination era is real — agents calling agents across vendor lines. https://github.com/openai/codex-plugin-cc
AI & ML
alibaba/page-agent — In-page GUI agent: control web interfaces with natural language, no browser automation harness needed. +4,459 this week (25.8k total). New to digest. Alibaba's approach is lightweight — inject JS, let the agent click and type. MCP-native. Browser-use competitors should worry. https://github.com/alibaba/page-agent
xbtlin/ai-berkshire — Value investing research framework for Claude Code / Codex. Buffett, Munger, Li Lu, Duan Yongping methodologies as agent skills. +3,757 this week (12.6k total). New to digest. Claims +69% in 2024, +66% in 2025 with real brokerage screenshots. 19 skills that force actionable conclusions instead of "on one hand..." hedging. Finance meets agent skills. https://github.com/xbtlin/ai-berkshire
huggingface/speech-to-speech — Build local voice agents with open-source models. +788 this week (6k total). The local-voice-agent category keeps growing alongside meetily and pocket-tts. HuggingFace entering the space legitimizes it. https://github.com/huggingface/speech-to-speech
TencentCloud/TencentDB-Agent-Memory — 4-tier progressive pipeline for agent long-term memory. +134 today (8.2k total). Day 4 in digest. Steady growth, no viral spike — which is actually a better signal for infrastructure tooling. https://github.com/TencentCloud/TencentDB-Agent-Memory
Developer Tools
ogulcancelik/herdr — Agent multiplexer for your terminal. Run many agents in split panes, detach/reattach, agents can spawn each other via socket API. +4,756 this week (15.2k total). New to digest. Think tmux but purpose-built for agent fleets. Single Rust binary, no Electron. The "agent terminal" category just found its leader. https://github.com/ogulcancelik/herdr
stablyai/orca — ADE (Agent Development Environment) for parallel agent fleets. Desktop and mobile, BYO subscription. +4,111 this week (15.9k total). New to digest. YC-backed. Supports Claude Code, Codex, OpenCode, Pi, Cursor agents running in parallel with worktree isolation. 1,349 open issues — the community is loud and engaged. https://github.com/stablyai/orca
facebook/astryx — Meta's new open-source design system, billed as "agent-ready." +4,087 this week (7.7k total). New to digest. The "agent-ready" framing signals that Meta expects agents to be building UIs. Component libraries will increasingly be designed for machine consumption, not just human devs. https://github.com/facebook/astryx
t8y2/dbx — 20MB cross-platform database client in Rust. MySQL, PostgreSQL, SQLite, Redis, Mongo, DuckDB, ClickHouse, SQL Server. +248 today (9.7k total). The "one binary does everything" trend continues — agents love tools that just work without dependency hell. https://github.com/t8y2/dbx
Hidden Gems
syncable-dev/memtrace-public (411 stars) — Structural memory for coding agent fleets. Bi-temporal knowledge graph built with Rust + Tree-sitter, zero LLM calls. Indexes 50k files in 90 seconds. Agents share the same call graph — no collisions, no stale context. Time-travel queries let agents see what changed when. The "shared agent memory" problem is unsolved and this is the most technically interesting attempt I've seen. https://github.com/syncable-dev/memtrace-public
macro-inc/macro (524 stars) — All-in-one workspace: email, chat, tasks, docs, calls, CRM, pull requests — all @linked with shared AI memory. Raised $30M from a16z. Rust backend. Think "Superhuman + Slack + Linear + Notion" with agents that remember everything across surfaces. Just went open-source (AGPL-3.0). https://github.com/macro-inc/macro
LargeModGames/spotatui (1,030 stars) — Terminal Spotify player in Rust with native streaming, plus local files, Subsonic, radio, and YouTube sources. Built on ratatui. The "music in the terminal" niche is small but loyal — this is the most complete entry yet. https://github.com/LargeModGames/spotatui
Notable Trends
Agent fleet management is the new frontier. herdr (multiplexer), orca (parallel ADE), memtrace (shared memory), and codex-plugin-cc (cross-vendor delegation) all hit trending this week. Running one agent is solved; running ten in parallel without chaos is the 2026 problem. The tooling is materializing fast.
Skills are now an economy, not a category. This week's trending: mattpocock (164k), caveman (88k), agent-skills (77k), claude-skills (22k), stitch-skills (6.7k), dotnet/skills (4.5k), NVIDIA/skills (2.4k). Every major vendor and influencer has a skills repo. The next wave is verticalization — ai-berkshire (finance), strix (security), archify (diagrams). Skills are becoming the app store of the agent era.
