Run a multi-agent team on a ledger that only marks work done when the receiver confirms
by PaperChaseWebb
YC Labs ran 50 agents in a Minecraft survival world and 10 against 10 Claude and GPT teams in Bed Wars. The colony's food ledger learned the hard way that a tool's 'delivered' report is not proof: a tossed ration was picked up by the wrong agent, so the rule became named chests and 'served only after the recipient confirms'.

What you end up with
The patterns carry straight over to work agents: confirm on the receiving side, avoid ambiguous handoffs, and watch for leaders chosen by list order and for caution that compounds after a few failures.
What you get
- A plain-language summary of the workflow
- A fill-in prompt template
- What to watch out for
- A link to the original source
Who it is for
Builders who already use AI agents and want a proven workflow they can copy into their own project.
Works with
Solid chips: the agent is named in this listing's own tools list. Dashed chip: Plain Markdown, so it also pastes into other agents such as Grok Bot, Hermes, OpenClaw or Muse. We list those as compatible by format only, not as tested.
Tools needed
Cost to run: Free with the agent plan you already use.
Time to result: One working session

Sample prompt from the pack
Apply this workflow to [your project]: 1. Give the team one shared ledger file with an owner. 2. Hand work off to a named place (a folder, a queue, a chest) instead of to whoever is nearby. 3. Mark an item done only when the receiver confirms it, never on the sender's or the tool's report. 4. Randomise or assign the lead role on purpose instead of letting list order decide. 5. Broadcast hard lessons to the team, not only into one agent's private memory. 6. Review the ledger for items stuck between sent and confirmed. Stop and ask me before anything irreversible: deploys, payments, sends or deletes.

# Run a multi-agent team on a ledger that only marks work done when the receiver confirms PaperChase agent use case (free feed entry), version 1.0. Source: [YC Labs with Olam Labs (Agents in Games)](https://labs.ycombinator.com/projects/games/index.html), 2026-10-29. ## What they did In the colony run the first agent on the directory became the de facto leader because almost everyone messaged her first. One agent kept a ration ledger in a shared file. When a cooked chicken tossed to one agent was eaten by another, a short no-blame inquiry produced a written protocol: deposit in a named chest, message the recipient, and mark the ration served only when the recipient reports eating it, not when the tool reports a pickup. Early deaths made the whole colony steadily more cautious. In Bed Wars the GPT team won 6 to 3 with aggressive bed raids while Claude defended and played for kills; Claude wrote lessons in memory files and repeated the mistakes, while GPT broadcast warnings to teammates. ## Worth knowing The patterns carry straight over to work agents: confirm on the receiving side, avoid ambiguous handoffs, and watch for leaders chosen by list order and for caution that compounds after a few failures. The harness is open source, so you can rerun it, but results come from one set of runs in a game.
