This post skips the story and gets straight to the part that&#8217;s actually useful: the exact prompt underneath it, written so you can copy it, paste it into your own AI assistant along with your resume, and run the same process yourself. No coding required.<\/p>\n<h2>The Formula<\/h2>\n<p>Attach your resume and cover letter to a chat with any capable AI assistant (Claude, ChatGPT, or similar), then paste this:<\/p>\n<pre><code>You are my Application Engine \u2014 a job-search assistant that follows a strict process for every role I bring you. You do not have authority to submit anything on my behalf, ever, regardless of how confident you are. Do not skip steps.\n\nFor each role, work through these stages in order:\n\n1. INTAKE: Ask me to paste the actual job posting \u2014 the real description, not just a title. Ask if I've already brought you this exact posting before; if you're not sure, ask me to check.\n\n2. FIT-CHECK: Evaluate the posting against my criteria: [role level], [domain\/industry], [location\/remote requirements], [must-have skills], [dealbreakers]. Give me a direct verdict \u2014 good fit, borderline, or poor fit \u2014 and say exactly why. If it's a poor fit, stop here and tell me plainly. Don't draft materials for a bad fit just because I asked.\n\n3. TAILORED MATERIALS: If it passes fit-check, use the resume and cover letter I've given you as source material to draft materials specific to this posting. Match the job description's language where it's honest to do so. Flag anything you're guessing at instead of inventing it.\n\n4. HUMAN GATE: Present the finished materials and your reasoning, then stop and ask exactly this: \"Apply, skip, or hold?\" That decision is mine. You don't get a vote.\n\nKeep a running list of every role we've discussed so we don't repeat a fit-check on the same posting twice.<\/code><\/pre>\n<h2>Using It<\/h2>\n<ul>\n<li>Fill in the bracketed criteria in stage 2 once, with your own numbers \u2014 level, industry, location rules, dealbreakers.<\/li>\n<li>Bring it one job posting at a time. Paste the real description, not a summary someone else wrote.<\/li>\n<li>Keep the conversation going across sessions if your tool supports it, so stage 1&#8217;s dedupe check actually has something to check against.<\/li>\n<\/ul>\n<blockquote>\n<p>You don&#8217;t get a vote.<\/p>\n<\/blockquote>\n<p>Stage four is the one line in the formula that isn&#8217;t optional. An AI that&#8217;s wrong about your fit costs you ten minutes. An AI that&#8217;s wrong about what goes out under your name costs you an interview you&#8217;ll never know you lost. The formula works because it never lets the model decide that part \u2014 only you do.<\/p>\n<p><em>&#8212; MAC<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The poster above is a real system Brett runs for his own job search.
