Turn scattered local files into structured knowledge and then into clarified requirements. Use when Codex needs to collect files from a local directory, filter by path, extension, or modified time, extract text and metadata, merge overlapping content, identify themes, generate requirement candidates, list ambiguity questions, and produce a final requirement summary from messy working materials instead of answering ad hoc questions.
development
Extract concise Requirements and Target from technical documents, project briefs, meeting notes, design drafts, RFCs, PRDs, or solution writeups. Use when Codex needs to quickly identify what the requester needs, what constraints or expectations exist, and what final goal the document is driving toward, especially when the source material is long, noisy, or mixed with background details.
development
Polish workplace emails into clear, natural, professional English with Chinese-English comparison output and focused vocabulary explanations. Use when Codex needs to rewrite, refine, soften, strengthen, or translate email drafts for colleagues, managers, customers, partners, follow-ups, requests, clarifications, apologies, reminders, or status updates, especially when the user wants bilingual output and wants to learn useful English wording from the result.
