The agents run in the cloud in Devin, but the structure does not depend on that product. It is one company's current practice, described by the speaker as likely to change within a week. Source video "How One Founder Manages 20 AI Coding Agents at Once - Ryan Carson, Untangle" by **AI Engineer** — [Watch on YouTube →](https://youtube.com/watch?v=BTtyguoPvBU) The speaker names Devin as his harness; the roles below are generic sessions, as he says himself. ## The structure 1. **Humans at the top** set priorities and talk to customers. 2. **A manager agent is just a session** (he names it "engineer manager") that never writes code. He talks to it, mostly by voice. 3. **The manager works from a ticket board** (Linear here). One ticket should be one pull request, and the manager pulls tickets by dependency. 4. **One manager runs about 5 to 25 builder agents at once**, about 20 typically. The limit is how much you can follow by talking to the manager. You never open or talk to the builder sessions directly. 5. **An automation forces the manager to read every child session** every 15 minutes (the setting says 10, he settled on 15) and push things along. It is a scripted automation, because the manager cannot be trusted to do this on its own. 6. **Each builder calls a review agent** and loops at most about three times. If important bugs remain after three passes, the problem bubbles up to the manager and, if needed, to a human. 7. **A QA agent** runs as a child of the builder. He says agents are cheap enough to spin up freely as long as they do not hold up the merge queue. 8. **Every builder records a video** of the feature being used and its tests passing (a built-in test feature in Devin; build your own if your harness lacks it). A human product owner has to watch it before shipping. 9. **A merge-queue manager** coordinates the wave of PRs, for example database migration numbers that agents would otherwise collide on. They also use GitHub merge queues. ## Across a team - With about 10 people, each has one or two engineering-manager sessions, and the sessions message each other. He says this is built into Devin and probably into whatever harness you use, and that allowing it is important. - He argues against local development: coding with a cloud agent is what makes this possible. - His advice on the video step: it is the one place not to cut corners. On a phone he could not see the video well enough and was tempted to approve it anyway. ## How they hire (the speaker's method) 1. No pre-screens or video calls at first, because they bias the decision. The only question is whether the candidate can operate an agent. 2. Candidates submit a roughly 45-minute full-screen recording of shipping a feature (a PR) on an app they already maintain, with no instructions. 3. The videos go to a ranking agent that watches them and stack-ranks the candidates. He first ignored its top pick and later thought it had been right. 4. The top five are paid a fixed fee for a 16-hour project, under an NDA with the screen recorded, to get a real PR ready to merge, and those videos are ranked too. He watched all 16 hours of the last round himself. 5. A call happens only with the finalists, at the end. ## Caveats - One company's practice in one product area. The numbers (20 builders, 15 minutes, three review passes) are his tuning, not recommendations. - He expects the process to be obsolete within a week; read it as a snapshot. - Candidate videos fed to a model raise privacy and consent questions that the talk does not address. - No commands or configuration files are shown; the reproducible part is the structure above. ## More OpenClaw & Claude Code news [▶ Claude Fable 5.2: $8/$40 per MTok, a fast mode, a new Claude Code default, and what one reviewer found, checked against Anthropic's pages 2026-11-10](https://openclawdatabase.com/news/videos/2026-11-09-claude-fable-52-price-fast-mode-claude-code-default-checked-against-anthropic/) [▶ Running several coding agents with full access safely: Docker Sandboxes (sbx), a network policy, secrets kept outside, and three tests 2026-11-10](https://openclawdatabase.com/news/videos/2026-11-06-docker-sandboxes-sbx-agents-full-access-network-policy-secrets-multi-agent-team/) [▶ Your agent can pay: six attacks on x402 payments (price swap, duplicate payment IDs, free shopping, cache, look-alike sellers, prompt injection) and the fix for each 2026-10-30](https://openclawdatabase.com/news/videos/2026-10-30-x402-agent-payments-six-attacks-price-duplicate-cache-injection-fixes/) [▶ Claude Code effort levels tested: the same Opus 5.5 build at low, medium, high, extra high and max 2026-10-30](https://openclawdatabase.com/news/videos/2026-10-30-claude-code-effort-levels-tested-low-to-max-trip-splitter/) [▶ Telling Claude to "make it better" 100 times: the exact prompt, a clean-room setup, and where Sonnet and Opus 5.5 started overbuilding 2026-10-30](https://openclawdatabase.com/news/videos/2026-10-30-claude-100-rounds-make-it-better-sonnet-vs-opus-overbuilt-site/) [▶ Qwen Audio Agent as a voice front end for Claude Code: install, config.env, gateway, and what interruption and cancel really do 2026-10-30](https://openclawdatabase.com/news/videos/2026-10-29-qwen-audio-agent-voice-front-end-claude-code-gateway-setup/) [See all OpenClaw news →](https://openclawdatabase.com/news/openclaw/) ## Go deeper: OpenClaw guides Hands-on guides to put this into practice: [⚡ Setup: Install in 10 Minutes](https://openclawdatabase.com/openclaw/setup/) [🔐 Security Hardening](https://openclawdatabase.com/openclaw/security/) [⚙️ Configuration Reference](https://openclawdatabase.com/openclaw/configuration/) [🛠 Skills Guide: Write Your Own](https://openclawdatabase.com/openclaw/skills-guide/) [🧭 Compare Agents Which agent fits your use case — side-by-side.](https://openclawdatabase.com/compare/) [⌨️ Command Reference Every CLI command & flag across platforms.](https://openclawdatabase.com/commands/)
