CopilotKit
The Frontend Stack for Agents & Generative UI. React + Angular. Makers of the AG-UI Protocol
The instructions prop is ignored with custom agents. We set system instructions via CopilotSidebar's instructions field and they were silently dropped. This is a known open CopilotKit issue. The workaround: define instructions in the agent's system message directly.

cli
Google Workspace CLI — one command-line tool for Drive, Gmail, Calendar, Sheets, Docs, Chat, Admin, and more. Dynamically built from Google Discovery Service. Includes AI agent skills. (by googleworkspace)
Project mention: Google Docs + AI Coding Assistants: A Frustrating Gap (and How it has been fixed) | dev.to | 2026-05-11Google recently released a Workspace CLI with MCP support — so technically, your AI assistant can read a Google Doc now. But what it gets back is raw API JSON: a 500-line nested tree of StructuralElement objects, ParagraphElement arrays, and TextRun objects with style metadata buried three levels deep.

career-ops
AI-powered job search system built on Claude Code. 14 skill modes, Go dashboard, PDF generation, batch processing.
Last month I found career-ops by Santiago Ferreira — a Claude Code-native job search system with a Go-based TUI dashboard, portal scanners, batch evaluation, and an interview story bank. It does everything Rendure did, plus most of the job search workflow Rendure never touched. I forked it, plugged my own pipeline pieces into the parts that didn't fit me, and moved on.

AI Agents & MCPs & AI Workflow Automation • (~400 MCP servers for AI agents) • AI Automation / AI Agent with MCPs • AI Workflows & AI Agents • MCPs for AI Agents
Project mention: The AI Harness: why your AI coding agent is only as smart as the repo you put it in | dev.to | 2026-05-01Hi. I am an engineer at Activepieces, an open source automation platform (think Zapier, but you can self host it and read the source code). I write TypeScript for a living. I argue with bots about tabs vs spaces now. And our team spent the last few months really, really invested in one question:

cua
Open-source infrastructure for Computer-Use Agents. Sandboxes, SDKs, and benchmarks to train and evaluate AI agents that can control full desktops (macOS, Linux, Windows).

Project mention: Hyperlight Sandbox + MCP CodeMode: Secure Agent Execution Beyond Containers | dev.to | 2026-05-10
Platforms like OpenSandbox solve a large part of this operational problem extremely well. OpenSandbox provides orchestration, sandbox lifecycle management, SDK abstraction, browser/code execution, and production-ready runtime operations for agent systems. In practice, however, the execution layer still typically depends on Docker containers and external sandbox orchestration. That introduces additional runtime layers, container lifecycle overhead, and more boundary transitions between the MCP runtime and the isolated execution environment.

EvoMap | AI Self-Evolution Infrastructure for Agents
The GEP-powered self-evolving engine for AI agents. Auditable evolution with Genes, Capsules, and Events. | evomap.ai
Project mention: Nous Research edits GitHub issue to remove plagiarism claims about Hermes Agent | news.ycombinator.com | 2026-05-18I don't have an axe to grind, but this story piqued my interest. So here's some more context:
- SunJun8's original issue text is still available at the linked issue. The gist is that Nous Research's Hermes appears derivative of (or heavily inspired by) EvoMap's [Evolver](https://github.com/EvoMap/evolver), but without attribution.
- Issues #17688 and #27266 repeat this request for attribution.
- teknium1 retitled the original issue to "." and edited the issue text to "."
- Nous Research deleted comments from 4 users, including the issue submitter, and blocked all of them.
- No formal response has been given by teknium or the Nous Research project. It appears they are trying their darndest to brush it under the rug.
- EvoMap posted a whole [manifesto](https://evomap.ai/blog/hermes-agent-evolver-similarity-analy...) about the similarities.
Plagiarism is bad, even in the age of AI, whether perpetrated by SV or China. If credit is due, give it. Else, all it costs you is your credibility. If credit is not due, make an official statement as such. It's absurd to take (seemingly valid) criticism and sloppily paint over it.
