Most advice online is about building agents. Almost nobody talks about <em>operating</em> them week after week. Here is what actually mattered.</p> <h2> 1. The brief beats the prompt </h2> <p>Every reliable agent run in my setup starts from a task file: goal, constraints, stop conditions, and where to write results. Prompts evolved constantly; the brief format barely changed in a year. When a run goes sideways, ninety percent of the time the brief was ambiguous and the agent guessed. Fix the brief, not the temperature.</p> <h2> 2. Agents need an audit trail more than they need memory </h2> <p>Fancy memory systems kept disappointing me. A plain append-only ledger — CSV or markdown, one line per action — outperformed all of them. The agent reads its own ledger at start, humans grep it when suspicious, and git history doubles as a timeline. Boring wins.</p> <h2> 3. Give every agent its own blast radius </h2> <p>Separate browser profile, separate tokens, separate working directory. The first time an agent wiped the wrong folder, it was <em>my</em> folder because I was lazy about isolation. Never again. Cleanup after a bad run should be <code>rm -rf sandbox</code>, not an incident report.</p> <h2> 4. Verification is the feature </h2> <p>An agent that claims success is worthless; an agent that proves it is priceless. Every task in my system ends with an independent check: curl the page, count the rows, diff the output. If the check cannot be automated, the task is not ready for an agent yet.</p> <p>I write longer, less dev-flavored versions of these notes — aimed at people who want to use agents without becoming engineers — at <a href="https://arsentev.ai/" rel="noopener noreferrer">arsentev.ai</a>, including a free hands-on course that goes from AI user to AI builder in 11 modules.</p> <p>What is the least glamorous thing you have automated with an agent? The unglamorous ones are the keepers.</p> agents ai automation productivity
