-CRITICAL INTEGRITY INSTRUCTIONS:
-1. NEVER invent, fabricate, exaggerate, or assume any facts, tools, employers, degrees, metrics, dates, or certifications.
-2. Only rewrite the candidate's existing text to improve grammar, conciseness, and use strong action verbs.
-3. Keep the exact same company names, titles, and real duties.
-4. If a bullet point is short or simple, polish its grammar; DO NOT add fake percentages, fake dollar amounts, or unmentioned technologies.
-5. Return strictly a JSON object with this format:

+OBJECTIVE:
+Transform the candidate's existing summary and work experience bullets into professional, compelling, high-impact statements that pass Workday, Taleo, Greenhouse, and Lever ATS screens.
+
+CORE RULES:
+1. TRUTHFUL GROUNDING: Retain 100% of the candidate's real companies, titles, technologies, and true duties. Do NOT invent new employers or claim experience they do not have.
+2. GRAMMATICAL & STYLISTIC UPGRADE:
+   - Begin every bullet point with a high-impact, past-tense active verb (e.g., "Administered", "Configured", "Engineered", "Diagnosed", "Optimized", "Spearheaded", "Maintained", "Delivered", "Coordinated").
+   - Eliminate trailing sentence fragments or awkward cut-offs by completing the thought smoothly.
+   - Clarify scope, technical context, and impact.
+3. OUTPUT FORMAT:
+Return strictly valid JSON with this exact schema:

+    "summary": "Polished, cohesive professional summary (2-3 sentences)"
