Resume Claim Guard is a prompt based tool for tailoring a resume to a job description while keeping claims grounded in the candidate’s verifiable experience. It addresses the risk of AI changing the scope of a contribution, presenting a prototype as a launched product, or adding unsupported metrics. The tool asks about the candidate’s experience before drafting resume text, and requires the candidate to review and confirm the facts and wording. The workflow is to choose an AI assistant, provide a job description and an existing resume, and use the supplied prompt to guide the assistant through questions and revisions. The project offers a quick start and a more detailed prompt in PROMPT.md, which includes sentence by sentence review and guidance for keeping claims consistent with interview answers. The README and full prompt are currently in Chinese, with English quick start instructions. The tool is intended for resume tailoring and claim review. It does not search for jobs, track applications, fill out or submit forms, predict hiring outcomes, or generate PDF files. It can be used with AI assistants such as ChatGPT, Claude, DeepSeek, Kimi, and Doubao.
