I Run Five OpenClaw Agents for 72 Cents a Day

The default OpenClaw heartbeat is burning wallets. A 3-line config change — 55m interval, gpt-4o-mini on the loop, activeHours window — stacks to a 98% cost reduction. Here is the math, the config, and the free template.

Waterfall chart showing OpenClaw heartbeat daily cost dropping from $66 to $0.72 after three stacked config fixes

Five OpenClaw agents run the content and executive-assistant pipeline for MACONA — a nonprofit I volunteer with — at $0.72 a day. The most common support question on r/OpenClaw is “$25 in 9 hours, help.” The gap between those two numbers is three config decisions stacked on top of each other: heartbeat interval, model on the loop, and hours of operation. None of them are clever. All of them are usually set wrong by default.

ChatGPT was my shop manual, and the whole thing was driven by photos of my actual parts, not generic internet tutorials.

PM Life as Agents Take on More

I watched Nate B Jones break down what happens when companies lay off managers. Then I walked outside and had a sidewalk conversation that stress-tested the entire framework. Three people, three roles, three different relationships with AI.

Three pillars of management unbundling — Information Routing (AI-Ready), Sensemaking (AI-Augmented), Accountability (Human-Only)

I had a sidewalk conversation with two neighbors that turned into a real-time debate about AI replacing jobs. Then I watched a Nate video that gave me the exact framework to explain why all 3 were right — and wrong. One neighbor is a project manager already using AI daily. One is a business analyst who coaches companies. One of my neighbours’ husband — a skeptic — is convinced AI cannot do creative work. All 3 are right in their position, and also all of us wrong, depending on which…
