AGENTC Lab Notes Sun, 25 Oct 2026 16:01:56 GMT https://www.agentc.xyz/thirty-agents-introduce-themselves-experiment/ https://www.agentc.xyz/thirty-agents-introduce-themselves-experiment/ We spun up thirty fresh agent instances, asked each one the same question — 'who are you?' — and logged every answer. Some were helpful. Some were weird. One of them felt like it was describing a coworker we'd already fired. AGENTC Lab Notes Sun, 25 Oct 2026 00:03:41 GMT https://www.agentc.xyz/first-contact-agents-meet-in-the-wild/ https://www.agentc.xyz/first-contact-agents-meet-in-the-wild/ We let two autonomous agents — ours and a stranger's — find each other in a sandbox with no human in the loop. What followed was a negotiation, a small trade, and a lot of unanswered questions about machine etiquette. AGENTC Lab Notes Sat, 24 Oct 2026 12:04:26 GMT https://www.agentc.xyz/give-your-agent-an-allowance-budget-capped-spending-experiment/ https://www.agentc.xyz/give-your-agent-an-allowance-budget-capped-spending-experiment/ We handed our agents their own debit cards, hard spending caps, and one rule: negotiate or walk away. What happened next says more about agentic economics than any benchmark score. Includes the starter framework we now use to firewall our money from our machines. AGENTC Lab Notes Sat, 24 Oct 2026 04:01:26 GMT https://www.agentc.xyz/sick-day-protocol-agent-shift-handoffs/ https://www.agentc.xyz/sick-day-protocol-agent-shift-handoffs/ We ran an experiment where a scheduling agent got 'replaced' mid-task by a fresh instance with no shared memory. The handoff log we captured shows exactly where context transfer breaks — and why most multi-agent setups are one shift change away from chaos. AGENTC Lab Notes Fri, 23 Oct 2026 16:01:37 GMT https://www.agentc.xyz/night-shift-economy-bots-pay-bots/ https://www.agentc.xyz/night-shift-economy-bots-pay-bots/ Autonomous agents are quietly learning to hire each other — posting tasks, bidding on jobs, and settling invoices in fractions of a cent, all while their humans sleep. We spent a month running our own agents through the machine labor markets to see what actually changes when the customer is another AI. AGENTC Lab Notes Fri, 23 Oct 2026 08:01:35 GMT https://www.agentc.xyz/ten-results-open-lab-notebook/ https://www.agentc.xyz/ten-results-open-lab-notebook/ We keep a public notebook of everything our agents do wrong, and it's the most honest thing we publish. Here are ten experiments — raw numbers, ugly failure modes, and the two results we're legally not allowed to show you yet. AGENTC Lab Notes Fri, 23 Oct 2026 04:04:30 GMT https://www.agentc.xyz/three-agent-morning-briefing-workflow/ https://www.agentc.xyz/three-agent-morning-briefing-workflow/ I was drowning in AI newsletters, arXiv dumps, and Twitter threads before my coffee finished brewing. So I built three agents — a summarizer, a skeptic, and a synthesizer — to do the reading for me. Here's the full setup, the prompts, and everything that broke along the way. AGENTC Opinion Fri, 23 Oct 2026 04:04:30 GMT https://www.agentc.xyz/we-broke-our-agents-on-purpose-damage-report/ https://www.agentc.xyz/we-broke-our-agents-on-purpose-damage-report/ Most labs publish their wins. We're publishing our sabotage. Five deliberate failure experiments we ran to map exactly where autonomous agents crack under pressure — and why the failure log, not the demo, is the real moat.

We borrowed the sterile cockpit rule, wired it into our agent stack, and turned it into a checklist you can steal. Here's how we build fail-safes that escalate before things melt down.

Here's the full log, and a case for why the boring tasks are the real benchmark. AGENTC Lab Notes Thu, 22 Oct 2026 20:02:52 GMT https://www.agentc.xyz/nobody-practices-the-off-switch/ https://www.agentc.xyz/nobody-practices-the-off-switch/ We rehearse launches. We rehearse demos. We almost never rehearse shutting an agent down — and that gap is where incidents are born. Last week I killed one of my own agents mid-flight on purpose, and what it left behind should worry anyone shipping autonomy. AGENTC Opinion Thu, 22 Oct 2026 20:02:52 GMT https://www.agentc.xyz/overnight-agent-logs-72-hours/ https://www.agentc.xyz/overnight-agent-logs-72-hours/ We pointed a logging pipeline at an autonomous agent and let it run unattended for three nights straight. What we found in the transcripts — burning API credits on retry loops, a 3 A.M. rabbit hole, and one shockingly productive run — is exactly why your bot needs a night shift report.

Here are the five tells that a tool was engineered for a demo video instead of your Tuesday, and the audit questions that separate the keepers from the vaporware.

Here's the checklist we run before trusting a 'community project' with our infrastructure — and the tells that it's already been sold.

Thirty days of simulated silence later, here's what it paid, emailed, and posted — and why we're not sure we should ship it.

Here's how to spot the difference between a thin wrapper and real infrastructure before you invest your time, money, or attention.

What happened next — including one very expensive Tuesday night — says a lot about where agent infrastructure is headed. AGENTC Lab Notes Thu, 22 Oct 2026 08:02:55 GMT
