'Make my resume better' has no target. Define what a good bullet looks like and the model can hit it.
Better is not an instruction
'Better' means nothing to a model, so it defaults to longer and more florid, which is worse. A resume bullet has a known good shape: action verb, technology, measurable result. Describe that shape and you have replaced a preference with a specification.
Show one bullet in the target form
One example does more than three sentences of description. 'Cut checkout latency 40% by migrating the payments service from REST to gRPC' tells the model the verb placement, the level of detail, and where the number goes, all at once. This is the cheapest few-shot you will ever write.
Say how many, and say nothing else
Ask for 'exactly three bullets as a markdown list and nothing else'. Resume prompts attract commentary, because the model wants to explain its choices. Closing the output format shuts that down.
Try it
Turn this into a spec with a worked example. Aim for a score of 85+.
47structure
Target: 85. Keep working the prompt. The score moves as you type.
⌃Role / persona: Open with a persona, e.g. "You are a senior backend engineer."
⌃Task clarity: Lead with one explicit action verb and object, e.g. "Refactor this function to…".
⌃Constraints: State limits and do/don't rules, e.g. "Keep it under 200 words. Do not invent APIs."
Want it as a form instead? The resume bullets template has all seven parts already in place. Replace the brackets and paste it. For practice against a fresh brief, there is a new drill every day.
