Prioritize relevance
A focused list built around the target role is easier to evaluate than an inventory of every tool you have touched.
Generate a focused skills shortlist from your experience and target job, then keep only the technical, professional, language, and domain skills you can genuinely demonstrate.

Quick answer
A resume skills generator is most useful as a discovery and prioritization tool. Feed it the target role and your actual background, then keep skills that are both relevant and defensible. The best final skills section is focused enough to scan and supported by evidence elsewhere in the resume.
What matters most
A focused list built around the target role is easier to evaluate than an inventory of every tool you have touched.
Organize programming languages, platforms, methods, domain skills, languages, or other families when grouping improves scanning.
Critical requirements should usually appear in experience, projects, education, or certifications as well as the skills list.
Inside PortCV
PortCV can use the resume context and target job to surface relevant skill ideas. Because the skill list sits inside the structured document, you can remove weak suggestions, reorder priority skills, and connect the strongest ones to experience or projects.
Open the resume engineGuide 01
Hard skills include technologies, software, methods, languages, machinery, or professional techniques. Domain skills reflect areas such as financial reporting, paid acquisition, clinical workflows, logistics, or curriculum design. Working skills describe how you operate—stakeholder communication, facilitation, coaching, or negotiation—but these are strongest when experience demonstrates them.
Avoid rating yourself with arbitrary stars or percentages unless a recognized standard defines the scale. Proficiency labels should communicate something a hiring team can interpret.
Guide 02
Identify required and preferred capabilities in the job description, compare them with your real background, then rank the overlap. A senior backend role and a junior frontend role may share 'JavaScript' but require very different supporting skills.
Do not add a keyword simply because the employer mentions it. If a required skill is missing from your history, acknowledge the gap rather than using a list to imply experience you do not have.
Guide 03
The skills block helps scanning, but high-value requirements should appear in context elsewhere. If you list SQL, point to analysis or data work. If you list project management, show a project, stakeholder decision, risk process, or delivery outcome.
Keep the section current. Remove obsolete or beginner-level tools that distract from the role you want now unless the posting explicitly makes them relevant.
Questions people ask
There is no universal number. Use a focused set that a recruiter can scan quickly and that reflects the requirements you genuinely meet.
A few may be useful, but evidence in experience usually carries more weight than listing generic traits such as leadership or communication.
AI can infer or suggest possibilities from the context you provide, but only you can verify whether a skill accurately represents your experience and proficiency.
