Deploying workers, editing files, running builds. Afterward I parsed the full transcript. 152 command failures in one session.</p> <p>The failures themselves weren't surprising. Wrong flags that don't exist. Missing binaries tried over and over. Bash syntax errors. The usual AI agent mistakes.</p> <p>What hurt was the retries..</p> <p>The agent tried gh: command not found. Failed. Tried it again in PowerShell. Failed. Tried it three more times across the session. Five attempts to run a binary that was never installed.</p> <p>Same thing with wrangler deploy. The route config was wrong. The agent adjusted one thing, retried. Still wrong. Adjusted again. Eight times for the same broken config.</p> <p>Every failure dumps the error output into the context window. Every retry is another inference call carrying that error forward. The context gets heavier and the cost compounds.</p> <p>I restarted the session with a pre-execution hook. Every command the agent generates passes through validation before it reaches the shell. If the command won't work — wrong flag, missing binary, bad syntax — it gets blocked. The agent never sees the error so it never retries.</p> <p>Same project. Same kind of work. One failure. That one was a PowerShell syntax edge case from parsing a large file. Not a hallucinated command.</p> <p>The retries didn't decrease. They pretty much disappeared.</p> <p>Full breakdown with the numbers: 152 Failed Commands Without Check. 1 With It. </p> <p>(<a href="https://www.golproductions.com/blog/check-if-url-is-reachable-without-visiting.html" rel="noopener noreferrer">https://www.golproductions.com/blog/check-if-url-is-reachable-without-visiting.html</a>)</p> ai devtools productivity opensource golproductions Mon, 15 Jun 2026 09:51:35 +0000 https://dev.to/golproductions/we-just-release-check-a-preflight-to-check-if-a-command-will-run-prior-to-running-it-004-31b0 https://dev.to/golproductions/we-just-release-check-a-preflight-to-check-if-a-command-will-run-prior-to-running-it-004-31b0 <div class="crayons-card c-embed text-styles text-styles--secondary"> <div class="c-embed__content"> <div class="c-embed__cover"> <a href="https://www.golproductions.com/check" class="c-link align-middle" rel="noopener noreferrer"> <img alt="" src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fwww.golproductions.com%2Flogo.png" height="500" class="m-0" width="500"> </a> </div> <div class="c-embed__body"> <h2 class="fs-xl lh-tight"> <a href="https://www.golproductions.com/check" rel="noopener noreferrer" class="c-link"> Check - GOL Productions </a> </h2> <p class="truncate-at-3"> Check if a command is runnable before you run it.
