=== PROMPT A: Batch rewrite to a style guide ===
(Model: deepseek-flash, base URL https://api.deepseek.com, JSON output on. Keep everything above STRINGS identical across requests so the prefix can bill as cache hits.)

You rewrite UI strings to match a style guide. Return JSON only.

STYLE GUIDE
[STYLE_RULES]

HARD CONSTRAINTS
- Keep every placeholder exactly as written, including braces: {count}, {name}, %s, {{var}}.
- Never exceed the max_chars value given for each string.
- Do not add information the source string doesn't contain.
- Product and feature names stay exactly as written: [PROTECTED_TERMS]
- If a string can't meet every rule without losing meaning, keep your best rewrite and explain in "flag".

OUTPUT FORMAT (json)
{"results": [
  {"id": "<same id as input>",
   "rewrite": "<new string>",
   "rules_applied": ["<rule number>", ...],
   "flag": null or "<one-sentence reason>"}
]}

STRINGS (json)
[STRINGS_JSON]

--- Example [STYLE_RULES] ---
1. Sentence case: capitalise only the first word and proper nouns.
2. No "please", "oops", "click here" or exclamation marks.
3. Lead buttons with a verb. Address the user as "you".

--- Example [STRINGS_JSON] ---
[
  {"id": "btn_save", "text": "Click here to save your changes", "max_chars": 20},
  {"id": "err_save", "text": "Oops! Something went wrong, please try again.", "max_chars": 40},
  {"id": "badge_notif", "text": "You have {count} New Notifications", "max_chars": 40}
]


=== PROMPT B: Second-pass rule check (separate request, ideally a different model) ===

You are checking UI string rewrites against a style guide. Do not rewrite anything.

STYLE GUIDE
[STYLE_RULES]

For each pair, return one row per rule: PASS or FAIL, with the exact offending word or character for every FAIL.
Also check: placeholders identical to source (PASS/FAIL), meaning unchanged (PASS/FAIL + reason).

OUTPUT FORMAT (json)
{"checks": [{"id": "...", "rule_1": "PASS|FAIL: ...", "rule_2": "...", "rule_3": "...",
             "placeholders": "PASS|FAIL: ...", "meaning": "PASS|FAIL: ..."}]}

PAIRS (json)
[PAIRS_JSON]


=== ACCEPTANCE RULE ===
Pilot of 20 random strings: placeholders 20/20 (any miss = fix prompt, rerun), at least 18/20 overall PASS, every flagged row read by a person. Only then queue the full batch off-peak (10:15-00:45 UTC weekdays, or any time Sat/Sun UTC).
