Models have gotten so good at understanding problems and executing that work that used to take hours now finishes in 10 to 15 minutes. As soon as I step away from my desk, the agent is already done and waiting on me. The AI is no longer my bottleneck. I am. Earlier this week I audited two weeks of my own Claude Code logs (1,402 sessions and 4,367 prompts). Regular chat prompts ran for a median of just 92 seconds before stopping to wait on me, and 74% finished in under 5 minutes. To break that bottleneck, I pointed my autonomous task loop (goal-loop) at my second brain (OpenBrain) to scan my projects in flight, pick the 5 highest-impact tasks, build and verify them, and repeat for 12 hours. It finished 14 waves (70 verified loops across 20 projects) while I worked on other things, plus a separate 4-hour run shipping features and bug fixes on my home-repair app (moHelp). Across my logs, goal-loop runs lasted 17x longer than regular prompts. Even so, my old goal-loop had a flaw. It started coding right away from a short prompt with an 8-pass cap, so when my intent was fuzzy, 42% of runs still parked early to ask me clarifying questions. Yesterday I upgraded goal-loop by wiring in an upfront interview skill (grill-me) before the agent touches a file, combining it with role engineering ideas from Nick Saraev and Anthropic's engineering team: 1. Have the agent interview you before it starts Instead of guessing from a one-line prompt, my upgraded goal-loop runs a 5-question interview upfront. It locks the multi-step finish line, what is out of bounds, and the exact files to touch so the agent can run for hours without checking in. 2. Lock a deterministic pass-or-fail test and one finished example In 82% of my regular prompts I had not given the agent a self-check, and in 99.8% I had not named a reference file to match. Claude Code creator Boris Cherny had an agent rewrite a desktop app over two weeks by comparing screenshots pixel by pixel until they matched, so I now hand my loop one finished example from my codebase and a test script the computer runs after every pass.
