Step 0: Set the rules
Here is my current resume: [paste it in full]. My target role is [the exact title from the posting]. Two rules before you start. First, never invent an employer, job title, date, credential, tool or number — this document already exists and every claim in it is mine. Second, do not regenerate the whole thing. I want a diagnosis and a diff, not a replacement. If you think a section should be deleted entirely, tell me and wait.
Step 1: Read it the way a stranger would
Read my resume once without knowing anything about me, then tell me what I do, what I am good at, and whether it looks like [the target role]. Then tell me what a reader could not tell me. Be specific about the parts you had to guess at, because that is the actual problem.
Step 2: Grade it and show your working
Give me a score out of 100 for each of four things, with the reason attached to each score: clarity — can a stranger state what I do after ten seconds; evidence — what proportion of my bullets contain a specific outcome rather than a duty; structure — would a parser extract my contact details, employers, titles, dates and skills correctly from this file; targeting — how well does this match [the target role]. Do not average them into one number. The lowest of the four is where the work is.
Step 3: Name the lines costing me the most
Quote my ten worst lines verbatim, in full, and for each one tell me in a single sentence what is wrong with it and what specifically would fix it. Quote them exactly — I need to find them in the document. Do not summarise or paraphrase my own words back to me.
Step 4: Propose the changes and wait
Give me a proposed edit list: Original line | Proposed line | Which of the four scores it improves | Why. Show me only the lines you want to change, not the whole document. Wait for me to approve or reject each one individually before anything is applied. If I reject one, leave it exactly as it was and do not argue for it.
Step 5: Rewrite the approved lines
For each approved line, write the replacement as: action verb, the specific task, the tool or method, and a result. Use only numbers, tools and outcomes already present in my original resume or supplied by me in this conversation. If a line needs a figure I have not given you, write it without the figure and add it to a NEEDS MY INPUT list. Never round a number up to make a bullet stronger, and never convert a team size into a percentage.
Step 6: Hand back the diff and the residual weaknesses
Give me the before and after side by side for every changed line, then the plain-text document with only those changes applied, then a short list of what is still weak and what I should not bother fixing. Tell me if any of my lines are already strong enough to leave alone — I want to know what not to change.
