+# Jamie FAQ Entry
+
+Generate, review, and edit Q&A entries for Jamie Clinic's KakaoTalk Plus Channel Kanana 상담매니저.
+
+## Directive
+
+Read and follow `custom-skills/42-jamie-faq-entry/code/CLAUDE.md` for the full skill directive.
+
+## Current Entries
+
+Load `custom-skills/42-jamie-faq-entry/shared/current-entries.md` before creating or reviewing entries to check for duplicates and maintain the 1-intent-1-answer rule.
+
+## Key Constraints
+- Q: sentence form, customer tone, <= 100 chars
+- A: 3-part structure (핵심→부가→CTA), <= 400 chars
+- Medical ad compliance (의료법 제56조): scan every draft for banned expressions
+- Brand tone: 격식체, 고객님/환자분, emoji max 1 at closing
+
+## Workflow
+1. Read the full directive from `code/CLAUDE.md`
+2. Load `shared/current-entries.md` for duplicate check
+3. Execute the requested task (create / review / batch)
+4. Validate char limits and compliance before presenting output
