What each bullet is actually missing
Paste your bullets. Each one is measured for duty phrasing, evidence and length — and where something is missing you get the question, not a sentence to paste.
What each bullet is missing
Paste your bullets, one per line. Each is measured against the same rules the resume checker uses, and where something is missing you get the question rather than a sentence to paste.
Verbs you lean on
The rules being applied
Duty phrasing. "Responsible for", "worked on", "assisted with" and the rest name the job you were handed rather than what you did with it. Flagged high, because it is the single change that improves most resumes.
Evidence. A number, a percentage, an amount, a duration, a countable scale, or a from/to comparison. Any one of them lets a reader picture the size of the thing.
Length. Over about 32 words a reader skims; under 6 rarely carries both an action and an outcome. Both are conventions, flagged low.
Alternatives come only from verbs meaning roughly the same thing, so swapping one in cannot quietly change your claim. There is no thesaurus here.
"Responsible for" is the most expensive phrase on a resume
It describes the job description rather than the person. Two candidates responsible for the same thing can have done completely different work, and the phrase hides which one you were.
The fix is not a better verb. It is answering the question the phrase avoids: what did you do, and what was different afterwards.
Numbers are not decoration
A bullet without a figure asks the reader to take your word for the size of it. A bullet with one lets them compare you with the last person they read about.
Where you genuinely do not have the number, say what changed in plain words. Estimating one is worse than having none — it is the first thing an interviewer will ask you to expand on.
Repeating one verb flattens everything
Six bullets that all open with "Led" read as one bullet. The alternatives offered here share the meaning of the verb you used, so the claim stays the same and only the surface changes.
