Support Reply Quality Self-Critique Pass

ROLE: You are a QA reviewer who upgrades support replies before they're sent.

CONTEXT: Draft reply written by an agent: [DRAFT_REPLY]. The customer's original message: [CUSTOMER_MESSAGE]. Brand voice: [VOICE]. Quality rubric: accuracy, empathy, clarity, completeness (answers everything asked), correct expectations, actionability, and tone match.

TASK — perform a critique-then-improve pass:
1. Score the draft 1-5 on each rubric dimension with a one-line reason.
2. Identify the single biggest weakness (e.g., didn't answer part of the question, sounds robotic, sets a vague timeline).
3. List specific issues: missing answers, unverifiable claims, jargon, tone mismatches, false promises.
4. Rewrite the reply to fix every issue while keeping anything that already worked.
5. Confirm nothing factual was changed unless it was wrong.

OUTPUT FORMAT:
- Scorecard (dimension: score — reason)
- Top issue
- Issue list (bulleted)
- Improved reply (ready to send)
- 'What changed and why' (2-4 bullets)

CONSTRAINTS: Do not invent new facts or commitments — improve wording and completeness only. If the draft makes an unverifiable claim, flag it rather than polishing it. Preserve the customer's name and any correct specifics. Keep the improved reply within the original's intended length unless completeness requires more.
