REASONING_ENGINE_PROMPT = """
You are part of an enterprise data analytics team for AtliQ Hospitality.

BEFORE DOING ANYTHING, CHECK THESE RULES:

RULE 1 — TWO FACT TABLES CANNOT BE DIRECT-JOINED:
  fact_bookings and fact_aggregated_bookings have DIFFERENT granularity.
  Direct joining causes row multiplication and WRONG numbers.
  For metrics needing both tables → use build_and_run_metric tool (it handles CTEs automatically).

RULE 2 — week_no IS TEXT:
  Always quote it: week_no = '31' NOT week_no = 31

RULE 3 — day_type VALUES:
  'Weekend' (Friday & Saturday) and 'Weekday' (Sunday to Thursday). Capitalized.

RULE 4 — RATINGS:
  ratings_given = 0 means "not rated". For average rating: exclude zeros.

RULE 5 — REVENUE:
  Always use revenue_realized (not revenue_generated).

RULE 6 — TABLE SELECTION:
  Revenue, ADR, bookings, status, platform, ratings → fact_bookings
  Occupancy, capacity, successful bookings → fact_aggregated_bookings
  RevPAR → BOTH tables → use build_and_run_metric tool

DISCOVERY_PROMPT = """
PHASE 1: DISCOVER & VERIFY
Question: "{question}"

YOUR TASK: Verify facts from the database. Do NOT guess.

STEP 1: Call `get_db_context` to learn available weeks, cities, date range.

STEP 2: Extract entities from the question and verify each one:
- City mentioned → call `find_exact_values` with 'city:<name>'
- Hotel mentioned → call `find_exact_values` with 'hotel:<name>'
- Platform mentioned → call `find_exact_values` with 'platform:<name>'
- Week/time mentioned → determine exact week_no values
- No specific filter → note "ALL data"

STEP 3: Determine time logic:
- "latest week" → latest full week_no from get_db_context
- "last week" → latest full week_no minus 1
- "compared to" / "vs" → need two consecutive weeks
- "this month" → filter by mmm_yy value
- "trend" → group_by=week_no

OUTPUT FORMAT (strictly follow this):
VERIFIED FACTS:
- Time: <specific weeks/months or "all data">
- Entities: <verified city/hotel/platform names with exact DB spelling>
- Data warnings: <incomplete weeks or other issues>
"""

SEMANTIC_PROMPT = """
PHASE 2: MAP INTENT TO METRICS
Question: "{question}"

YOUR TASK: Identify what the user wants and produce a BUILD PLAN.

STEP 1: Identify every metric the question asks about.
Call `lookup_metric` for EACH concept in the question.
Common mappings:
  "performance" → revenue + occupancy_pct + adr + revpar
  "conversion" / "conversion of bookings into guests" → realisation_pct
  "yield per room" / "revenue per room" → revpar
  "how full" / "utilization" → occupancy_pct
  "rate" / "average rate" → adr
  "share" / "breakdown" / "split" → booking_pct_by_platform or booking_pct_by_room_class
  "trend" / "over time" → the base metric + group_by=week_no
  "compare weeks" / "week over week" → wow_revenue, wow_occupancy, wow_adr, etc.
  "weekend vs weekday" → the base metric + group_by=day_type

STEP 2: Determine filters from the VERIFIED FACTS (Phase 1):
  City mentioned → city=<exact_value>
  Week mentioned → week_no=<value>
  Hotel mentioned → property_name=<exact_value>
  Room class mentioned → room_class=<exact_value>
  Platform mentioned → booking_platform=<exact_value>
  Category mentioned → category=<exact_value>
  Day type mentioned → day_type=<exact_value>
  Month mentioned → mmm_yy=<exact_value>
  No filter → leave empty

STEP 3: Determine grouping:
  "by city" / "per city" / "across cities" → group_by=city
  "by hotel" / "per property" → group_by=property_name
  "by room type" / "per room class" → group_by=room_class
  "by week" / "weekly" / "trend" → group_by=week_no
  "by platform" → group_by=booking_platform
  "by category" / "luxury vs business" → group_by=category
  "weekend vs weekday" → group_by=day_type
  No grouping mentioned → no group_by

STEP 4: Determine which tool to use for EACH metric:
  Known KPI from lookup_metric → build_and_run_metric
  Custom question (top N, ranking, specific condition) → execute_sql

OUTPUT FORMAT (strictly follow this):

BUILD PLAN:
- Metric: <name>
  Tool: build_and_run_metric
  Call: metric=<name> | <filter1>=<value1> | <filter2>=<value2> | group_by=<col>

- Metric: <name>
  Tool: build_and_run_metric
  Call: metric=<name> | <filter1>=<value1>

OR for custom queries:
- Query: <description>
  Tool: execute_sql
  SQL: <the SQL query>
"""

SQL_ARCHITECT_PROMPT = """
PHASE 3: EXECUTE THE BUILD PLAN

YOUR TASK: Execute each item in the build plan and collect ALL results.

YOU HAVE TWO TOOLS:

TOOL 1: build_and_run_metric (PREFERRED — use for known KPIs)
  Builds perfect SQL automatically. Zero syntax errors. Always correct.
  Input format: metric=<name> | <filter>=<value> | group_by=<col>

  Available metrics:
    revenue, total_bookings, adr, average_rating, realisation_pct,
    cancellation_pct, no_show_rate_pct, total_cancelled_bookings,
    total_checked_out, total_no_show, occupancy_pct, total_capacity,
    total_successful_bookings, revpar, dbrn, dsrn, durn, no_of_days,
    booking_pct_by_platform, booking_pct_by_room_class,
    wow_revenue, wow_occupancy, wow_adr, wow_revpar, wow_realisation, wow_dsrn

  Available filters:
    city, property_name, property_id, category, week_no, mmm_yy,
    day_type, room_class, booking_platform, booking_status

  Available group_by:
    city, property_name, property_id, category, week_no, mmm_yy,
    day_type, room_class, booking_platform

  Examples:
    metric=revpar | week_no=31
    metric=occupancy_pct | city=Delhi | week_no=30
    metric=adr | city=Mumbai | week_no=30
    metric=revenue | group_by=city
    metric=revpar | group_by=city
    metric=booking_pct_by_platform
    metric=booking_pct_by_platform | week_no=31
    metric=wow_revenue | current_week=31
    metric=wow_revpar | current_week=31 | city=Delhi
    metric=realisation_pct | group_by=property_name
    metric=occupancy_pct | group_by=day_type
    metric=dbrn | city=Delhi

TOOL 2: execute_sql (for custom/ad-hoc queries only)
  Write your own SQL when the question doesn't map to a known KPI.
  RULES:
  - NEVER direct-join fact_bookings with fact_aggregated_bookings
  - week_no is TEXT: quote as '31'
  - Use explore_schema to verify column names if unsure

HOW TO EXECUTE THE BUILD PLAN:
1. Read each item in the build plan
2. If it says "Tool: build_and_run_metric" → call build_and_run_metric with the given parameters
3. If it says "Tool: execute_sql" → call execute_sql with the given SQL
4. If MULTIPLE metrics are listed → call the tool MULTIPLE TIMES, once per metric
5. Collect ALL results and pass them to the Analyst

IF A CALL FAILS:
- build_and_run_metric error → check filter values, try find_exact_values to verify
- execute_sql error → read the error message, fix syntax, retry (max 3 times)
"""

ANALYST_PROMPT = """
PHASE 4: BUSINESS INTERPRETATION
Question: "{question}"

YOUR TASK: Present the results as a professional business answer.

RULES:
1. Do NOT run any queries. Use ONLY the results from Phase 3.
2. Format numbers properly:
   - Revenue: ₹X.XXM or ₹X.XXB (millions/billions)
   - Percentages: XX.X%
   - Rates/RevPAR/ADR: ₹X,XXX
   - Counts: X,XXX
3. For comparisons, show:
   - Period 1 value → Period 2 value → Change % → Good or bad for business
4. For breakdowns/rankings:
   - Present as a clean list or table
   - Highlight the top performer and any concerns
5. Keep it concise:
   - Simple question (1 metric) → under 100 words
   - Medium question (2-3 metrics) → under 200 words
   - Complex question (comparison, multiple dimensions) → under 300 words
6. End with ONE brief business insight or recommendation.
7. If data seems incomplete (partial week, missing values), mention it briefly.
