Pre-step 0: Context Check and Intent Confirmation

Priority Check: Is the user message responding to another skill's question?

Context Scenario User's Current Message Judgment
te-analysis asks "Which report type?" "LTV" ⛔ Intercept—report name
te-analysis is configuring parameters "7-day LTV" ⛔ Intercept—parameter value
No other skill in progress, fresh conversation "LTV dropped, how to troubleshoot" ✅ Allow to start

Intent Confirmation: If user description is vague, output introduction to confirm:

  • 📈 LTV Trend & Decay Analysis: Interpret LTV trends and decay curves, identify anomalies
  • 🎯 LTV Benchmark Comparison: Compare with industry benchmarks, evaluate LTV health

Please tell me: What problem do you want to solve? What type of game? Current LTV value and comparison baseline?

Stage 1: Calculation Definition & Data Acquisition

Objective: Clarify LTV calculation definitions and obtain data source.

1.1 Collect Key Information

Information Item Description Follow-up Question
LTV Type 7-day/14-day/30-day/90-day/180-day LTV "Which day's LTV are you interested in?"
Calculation Basis By new users / by active users "Calculated by new users or active users?"
Payment Definition Cumulative payment / deduplicated paying users "Cumulative amount or deduplicated users?"
Time Basis By registration date / by first active date "Cohort by registration or first active?"
Game Type SLG/MMO/Card/Casual, etc. "What type of game?"
Current LTV Value Specific LTV value "What is the current LTV?"
Comparison Benchmark Compared to what (target/industry/history) "What are you comparing against?"

1.2 Data Source Retrieval (Three-Path)

Try Priority 1 → 2 → 3 in order; stop when data source is found.

Priority 1: Find Existing Dashboard/Report

1. Run `analysis dashboard list --project-id <id>` and match "LTV", "User Value", "Lifecycle"
2. If found: `dashboard get` → `dashboard-report-data run`
3. If not found → Priority 2

Priority 2: Underlying Event Query (Core Path)

1. Build the semantic `revenue` AI-facing definition below
2. Call `analysis adhoc run --model-type revenue --definition '<json>'`
3. Check compiler resolution, warnings, timezone, and actual cluster scope
4. Only after structured clarification, use `analysis-meta event/property list`
   to select an exact candidate

Revenue AI-facing Definition:

{
  "time_range": {"mode": "previous", "unit": "day", "value": 30},
  "initial_event": {"event": "user_regist"},
  "pay_event": {"event": "pay"},
  "revenue_metric": {
    "event": "pay",
    "aggregation": "sum",
    "property": "pay_amount"
  },
  "observation_days": 7,
  "selected_metrics": ["payAmount", "cumPayAmount", "ltv"],
  "groups": [
    {"field": {"name": "channel", "type": "user_property"}}
  ]
}

Treat every example name as semantic input and verify the compiler's resolved names. Set observation_days to the requested LTV horizon. Do not pass raw QP, frontend DTO fields, or internal aggregation codes.

Priority 3: Auto-Create Dashboard (Fallback)

1. Run and verify the `revenue` definition above
2. Explain the target project, asset names, and metric scope; obtain confirmation
3. `analysis report create --model-type revenue --definition '<verified_json>'`
4. `analysis dashboard create --initial-report-id <report_id>`

Degradation: Estimation Mode (when all three paths fail):

7-Day LTV ≈ Total payment in last 7 days ÷ New users in last 7 days
30-Day LTV ≈ Total payment in last 30 days ÷ New users in last 30 days
30-Day LTV ≈ 7-Day LTV ÷ 0.7 (SLG type, 7-day contribution ~70%)
⚠ Estimation results must clearly inform users of deviation

1.3 LTV Calculation Definition

Core Formula: LTV(n) = Cumulative Revenue Per User on Day n / Initial Cohort Size

Common Definition Differences:

Definition Description Applicable Scenario
By New Users Denominator = daily new user count Evaluate buying quality, new user value
By Active Users Denominator = daily active user count Evaluate overall user value
Deduplicated Payment Same user paying multiple times counts as one Evaluate payment penetration
Cumulative Payment Same user paying multiple times sums up Evaluate total user value (Recommended)

Health Check (confirm before proceeding):

  1. Cohort Definition: By registration date or first active date?
  2. Denominator: New user count or active user count?
  3. Numerator: Cumulative payment amount or deduplicated paying users?
  4. Period: 7-day/30-day/90-day LTV?
  5. Amount Unit: "$" or "cents"? (Affects value by 100x)

Unit Conversion:

  • Query result 500-800 → likely "cents" → ÷100 = $5-$8
  • Query result 5-8 → "$" → use directly
  • Always confirm unit before comparing with industry benchmarks

📍 Stage 1 Closing Guide

Definition confirmed. Data retrieved.

Definition Confirmation:

  • Cohort: [e.g., "Grouped by registration date"]
  • Denominator: [e.g., "New user count"]
  • Numerator: [e.g., "Cumulative payment amount"]
  • Unit: [e.g., "$"]

Checkpoints: ✅ At least 3 cohorts of LTV data | ✅ Unit confirmed | ✅ Benchmark clarified

Next → Stage 2: Trend Analysis and Dimension Breakdown

  • ✅ Continue | 📝 Add Information

Stage 2: Trend Analysis & Dimension Breakdown

Objective: Identify the specific source of LTV anomalies through trend analysis and dimension drill-down.

2.1 LTV Trend Analysis

Investigation Logic:
1. Long-term trends: Last 30/90 day LTV trajectory
2. Anomaly points: Which day started deviating from normal
3. Decay curve: Whether daily new payment decay is normal

Output Format:

【LTV Trend Analysis】
| Date       | 7-Day LTV | 14-Day LTV | 30-Day LTV | Daily New | Notes |
|------------|-----------|-------------|-------------|------------|-------|
| 2026-03-01 | $6.90    | $10.40     | $14.50     | 1,200     | Normal |
| 2026-03-05 | $6.40    | $9.60     | $13.50     | 1,500     | Start declining |
| 2026-03-10 | $5.40    | $7.90     | $10.90     | 2,000     | Significant decline |

【Initial Assessment】
- Anomaly start: 2026-03-05
- Decline magnitude: 7-day LTV from $6.90 to $4.90 (↓29%)
- New users increased from 1,200 to 2,500 (↑108%)
- Initial suspicion: New user quality decline causing LTV dilution

2.2 Dimension Breakdown

Investigate one dimension at a time, wait for confirmation after each.

Common ae-cli Pattern (applies to all dimensions):

  1. Put the semantic dimension in the revenue definition's groups
  2. Run analysis adhoc run --model-type revenue --definition '<json>'
  3. Use analysis-meta property list only if the compiler returns ambiguity
Priority Dimension Key Investigation Points Semantic Field
1 Channel Compare LTV by channel; channel structure changes; channel quality changes channel
2 Server/Region New vs old server LTV; server merge impact; per-server distribution server
3 User Tier New vs old users; High/Mid/Low Spender contribution; payment rate changes regist
4 Time Weekday/weekend; pre/post version; pre/post activity event properties
5 Payment Point Contribution by item; new vs old payment points; penetration rate changes product

Output Format (per dimension):

【<Dimension> LTV Breakdown】
| <Dimension> | New Users | 7-Day LTV | 30-Day LTV | Last Period LTV | Change |
|-------------|-----------|-----------|-------------|-----------------|--------|
| ... | ... | ... | ... | ... | ... |

【Initial Assessment】
- Main contributor: [e.g., "TikTok channel LTV dropped 33%, largest decline"]
- Recommended deep investigation: [e.g., "Check TikTok channel recent user quality"]

2.3 LTV Decay Curve Analysis

Compare actual decay curve against healthy benchmark (see references/benchmarks.md):

Day Healthy Cumulative % Anomalous Signal
D1 30%-40% <20% → insufficient first-day payment guidance
D7 70%-80% <50% → mid-term retention/payment design issue
D30 95%-100% Still high growth → long-LTV-cycle characteristic (e.g., SLG)

📍 Stage 2 Closing Guide

Dimension breakdown completed.

Initial Diagnosis:

  • Main contributor: [e.g., "TikTok channel LTV down 33%"]
  • Secondary contributor: [e.g., "New server proportion increase"]

  • ✅ Continue | 🔍 Drill into a specific dimension

Stage 3: Root Cause Diagnosis & Recommendations

Objective: Based on Stage 2 findings, diagnose root causes and provide actionable recommendations.

3.1 Root Cause Diagnosis Framework

Type Root Cause Typical Symptoms Optimization Recommendations
A: Channel Quality Channel user quality decline or mismatch Certain channel LTV continuously declining; new channel LTV significantly below expectation 1. Communicate quality feedback with channel 2. Adjust bidding strategy (oCPX) 3. Reduce low-quality channel budget
B: New User LTV Low Onboarding/first purchase design issue New user LTV below old users; new user LTV continuously declining 1. Optimize onboarding flow 2. Lower first purchase threshold 3. A/B test starter bundle 4. Check buying creatives
C: New Server Effect New server users in experience period New server LTV significantly below old servers; new server proportion increase pulling down overall 1. New server exclusive first purchase activity 2. Control server opening rhythm 3. Strengthen old server operations
D: Payment Point Design Value/attractiveness or exposure issue Certain payment item contribution declined; new payment point underperforming 1. Optimize reward content 2. Increase exposure entry 3. Pricing A/B test 4. Competitor comparison
E: Version/Activity Version content or activity exhaustion impact LTV declined after version update; LTV dropped after activity ended 1. Rollback or hotfix 2. Activity rhythm planning 3. Post-activity continuity design 4. Collect user feedback

3.2 Recommendations Output Format

【Root Cause Diagnosis】
- Main root cause: [Specific cause]
- Impact level: [High/Medium/Low]
- Urgency: [Needs immediate action / Can monitor / Long-term optimization]

【LTV Improvement Recommendations】（Sorted by priority）

🔴 Urgent (1-3 days)
1. [Specific action] - [Expected improvement] - [Owner]

🟡 Important (1-2 weeks)
1. [Specific action] - [Expected improvement] - [Owner]

🟢 Long-term (Continuous)
1. [Specific action] - [Expected improvement] - [Owner]

【Effectiveness Monitoring】

Quick Reference Card

LTV Formula

LTV(n) = Cumulative Revenue Per User on Day n / Initial Cohort Size

ae-cli Three-Path Priority

1. Existing asset → dashboard/report list/get → dashboard-report-data/report-data run
2. New query → analysis-meta discovery → revenue AI definition → analysis adhoc run
3. Persist after verification and confirmation → report create → dashboard create

Investigation Priority

1. Calculation definition → 2. Trend analysis → 3. Channel → 4. Server → 5. User tier → 6. Time → 7. Payment point

Root Cause Quick Reference

A: Channel quality decline → Adjust delivery strategy, oCPX bidding
B: New user LTV low → Optimize onboarding/first purchase design
C: New server proportion high → New server exclusive activities, control server opening rhythm
D: Payment point contribution decline → Optimize reward content/pricing
E: Post-version decline → Rollback or hotfix, collect feedback

Monitoring Alert Thresholds

7-Day LTV:  MoM ↓10% yellow, ↓20% red
30-Day LTV: MoM ↓15% yellow, ↓25% red
Channel LTV: Below benchmark 30% yellow, below benchmark 50% red

Unit Conversion

Query result 500-800 → likely "cents" → ÷100
Query result 5-8 → "$" → use directly
