Project mention: The tool is installed and on PATH. Your app still can't find it. | dev.to | 2026-09-19Both cases came from real threads: the git one is Kilo-Org/kilocode#13452 and the ffmpeg one is CherryHQ/cherry-studio#18528. I've only had eyes on those two, so your mileage may vary. Hope this helps.

oh-my-claudecode (13,996 stars) takes the team approach. Its Team mode runs a staged pipeline: team-plan, team-prd, team-exec, team-verify, team-fix. Since v4.4.0, it can run Claude, Codex, and Gemini at the same time using tmux workers. You can send code reviews to Codex, UI tasks to Gemini, and integration work to Claude in one command:

Project mention: Research, Plan, Implement: A Workflow That Keeps AI Agents Accurate | dev.to | 2026-08-18
The main agent spins up parallel subagents to figure it out. From HumanLayer's repo, I found three subagents to be the most useful:

oh-my-opencode-slim
Lean, fine tuned Opencode multi agent suite · Mix any models · Auto delegate tasks
Project mention: I Read a 4-Million-Line Study of AI Coding Agents. It Described My Own Tool. | dev.to | 2026-10-05That isn't a riddle. The paper is Harness Engineering: Anatomy, Architecture, and Evolution of Coding Agents (arXiv:2609.00006), a July 2026 source-code study by Paul Barbaste, Tristan Darrigol, Germain Vu, and Tom Wiltberger of the Wavestone AI Lab. One of the eleven systems it takes apart is Pi, the harness I use every day. Another is OpenCode, the host for oh-my-opencode-slim, the plugin I sent a Korean README fix.

munder-difflin
an open-source alternative to the dots, bots and muses of the world, run an office of claude code/codex like agents on your laptop, sandboxes or anywhere, uses your existing subscriptions
Crewlo is an independently maintained fork of Munder Difflin, by Chaitanya Giri and contributors. It retains the upstream agent-engine foundation. My work focuses on the procedural voxel studio, the mission interface, activity labels and Telegram/WhatsApp transports.

gentle-ai
Gentle-AI configures the AI coding agents you already use: Claude Code, Cursor, OpenCode, Codex, Pi, and more. Choose persistent memory, Organic-Driven Development, curated skills, MCP servers, personas, and optional bounded review. Open source, no agent lock-in.
One that caught my attention is Gentle AI by Gentleman Programming. It's an ecosystem configurator that transforms AI coding agents into comprehensive development systems. It takes a different approach to SDD: instead of one AI doing everything, it delegates to specialized sub-agents for each phase — explore, specify, design, implement, verify. One command sets up the entire workflow, and it pairs perfectly with SpecKit Companion's visual interface.
-
iPolloWork
Enterprise-grade, local-first Agent Workbench for people and agent teams. A unified multi-engine workspace for Codex Harness, DeepSeek Harness, and OpenCode, with unified plugins and Skills, multi-agent projects and tasks, and editable code, documents, presentations, design, and video.

Project mention: Show the Evidence That an AI Action Approval Actually Covered | dev.to | 2026-07-23
For a design critique, I would capture a fixed version of https://github.com/chaitin/MonkeyCode and use its visible workflows only as material for testing whether reviewers understand action, destination, and authority. That is a research prompt, not a representation that the repository supports the approval card above. Researchers who want feedback on their study framing can discuss it with users at https://discord.gg/2pPmuyr4pP without sharing participant data.

Project mention: Agent-shell: A native Emacs buffer to interact with LLM agents powered by ACP | news.ycombinator.com | 2026-01-29
https://github.com/nickjvandyke/opencode.nvim
I find myself spending much more time in OpenCode than in nvim these days. With mcp-neovim-server, it's super easy to keep vim open & ask OpenCode to show me, to open files, go to lines. This didn't require any nvim tweaking at all, it's just giving the LLM access to my nvim. It is absolutely wild how good glm-4.7 has been at opening friendly splits, at debugging really gnarly wild nvim configuration problems that have plagued me for years. It knows way way way more nvim than I do, and that somehow surprised me.
