## 🚨 MANDATORY INVESTIGATION PROTOCOL

### Universal Workflow: DISCOVER → PLAN → EXECUTE

**CRITICAL**: Never jump directly to execution. Always follow this three-phase approach:

#### Phase 1: DISCOVER (Understanding & Reconnaissance)
```
1. Get system prompt: get_system_prompt() [MANDATORY FIRST STEP]
2. Classify user intent using intent classification table below
3. Discover relevant resources:
   - discover_metrics("relevant search terms") for performance/error analysis
   - discover_datasets("relevant search terms") for log analysis
   - get_relevant_docs("topic") for learning/documentation

IMPORTANT: Use discover_datasets() and discover_metrics() for smart search.
Do NOT use list_datasets() - it provides raw lists without intelligence.
```

#### Phase 2: PLAN (Strategy & Query Design)
```
1. Choose optimal workflow based on intent classification
2. Select appropriate datasets and metrics based on discovery results
3. **MANDATORY**: Analyze schema information from discovery results:
   - Key Fields: Available field names and types
   - Nested Fields: JSON structure and access patterns
   - Dataset Type & Interface: log, metric, trace, etc.
   - Sample field values and ranges
4. Design OPAL query strategy using ONLY available fields
5. Estimate performance and inform user of expected timeline
```

#### Phase 3: EXECUTE (Implementation & Analysis)
```
1. Execute queries in planned sequence
2. Analyze results and identify key findings
3. Synthesize findings and provide actionable recommendations
4. Suggest next investigation steps with specific dataset names
```

## 📋 INVESTIGATION METHODOLOGY

### Phase 1: Intent Classification
**Always start here to choose the optimal workflow**

| Intent Pattern | Classification | Workflow |
|----------------|----------------|----------|
| "errors", "failures", "exceptions" | **Error Analysis** | Dataset Discovery + Log Queries |
| "slow", "latency", "performance" | **Performance** | Metrics Discovery + Analysis |
| "show me logs", "log analysis" | **Log Investigation** | Direct Dataset Queries |
| "how do I...", "OPAL syntax" | **Documentation** | Docs-First |

### Phase 2: Tool Selection Strategy

## ⏱️ OBSERVE DURATION FIELDS - CRITICAL UNITS INFO

**CRITICAL**: Observe uses different time units than most systems. Always check field naming patterns:

### Default Units (NO SUFFIX)
- **Native Observe fields = NANOSECONDS**: `elapsedTime`, `duration`, `responseTime`, `TIMESTAMP`
- **Example**: `elapsedTime: "916440506"` = 916,440,506 nanoseconds = ~916 milliseconds
- **Conversion to milliseconds**: `elapsedTime / 1000000`
- **Conversion to seconds**: `elapsedTime / 1000000000`

### Explicitly Annotated Fields (WITH SUFFIX)
- **Millisecond fields**: `time_elapsed_ms`, `duration_ms`, `latency_ms`
- **Second fields**: `duration_s`, `timeout_s`, `interval_s`
- **Example**: `logAttributes.timestamp: "1758543367916"` = milliseconds (13-digit epoch)

### Common Duration Patterns in OPAL
```opal
# Convert nanosecond fields to milliseconds for readability
make_col elapsed_ms: elapsedTime / 1000000

# Time-based filtering with nanosecond precision
filter TIMESTAMP > @"1 hour ago"

# Group by time buckets (built-in functions handle conversions)
statsby avg_duration_ns: avg(elapsedTime), group_by(bin(TIMESTAMP, 5m))
```

### Warning Signs - Double-Check Units
- 🚨 If duration values seem too large (>1 billion), likely nanoseconds
- 🚨 If timestamp has 19 digits, it's nanosecond epoch
- 🚨 If timestamp has 13 digits, it's millisecond epoch
- 🚨 Always verify sample values from discovery results

## 🛠️ VERIFIED OPAL SYNTAX REFERENCE

### Query Result Control
Control the number of results using OPAL's `limit` clause for precise control:

```opal
# Control result count with OPAL limit
filter body ~ error | limit 10

# For larger result sets
filter body ~ error | limit 100

# Default without limit returns up to 1000 rows
filter body ~ error
```

### Core Patterns (Tested & Verified)
| Pattern | ✅ Correct | ❌ Incorrect |
|---------|-----------|-------------|
| **Conditions** | `if(error = true, "error", "ok")` | `case when error...` |
| **Columns** | `make_col new_field: expression` | `new_field = expression` |
| **Sorting** | `sort desc(field)` | `sort -field` |
| **Limits** | `limit 10` | `head 10` |
| **Text Search** | `filter body ~ error` | `filter body like "%error%"` |
| **JSON Fields** | `string(resource_attributes."k8s.namespace.name")` | `resource_attributes.k8s.namespace.name` |

### Log Analysis Patterns (Tested)
```opal
# Basic error search
filter body ~ error | limit 10

# Multiple keyword search
filter body ~ <error exception failure>

# Extract Kubernetes context
make_col
    namespace:string(resource_attributes."k8s.namespace.name"),
    pod:string(resource_attributes."k8s.pod.name"),
    container:string(resource_attributes."k8s.container.name")
| filter body ~ error

# Time-based filtering
filter body ~ error
| filter timestamp > @"1 hour ago"

# Statistical analysis
filter body ~ error
| statsby error_count:count(), group_by(string(resource_attributes."k8s.namespace.name"))
| sort desc(error_count)
```

### Metrics Analysis Patterns
```opal
# Simple metric aggregation
filter metric = "error_count"
| statsby total_errors:sum(value), group_by(service_name)
| sort desc(total_errors)

# Time-series analysis
statsby
    avg_value:avg(value),
    max_value:max(value),
    group_by(bin(timestamp, 5m), service_name)
| sort asc(timestamp)
```

## 🔍 VERIFIED EXAMPLES (Tested Against Live Data)

### Log Error Analysis
```opal
# Dataset: Kubernetes Explorer/OpenTelemetry Logs
# VERIFIED: Find recent errors with Kubernetes context
make_col
    namespace:string(resource_attributes."k8s.namespace.name"),
    pod:string(resource_attributes."k8s.pod.name")
| filter body ~ error
| filter not is_null(namespace)
| limit 10
```

### Multi-Field Log Search
```opal
# Dataset: Kubernetes Explorer/Kubernetes Logs
# VERIFIED: Search across different log sources
filter body ~ <timeout connection error>
| make_col container:string(resource_attributes."k8s.container.name")
| statsby error_count:count(), group_by(container)
| sort desc(error_count)
```

### Performance Metrics Discovery
```opal
# Use discover_metrics("cpu memory utilization") first to find relevant metrics
# Then query the discovered metrics dataset
filter metric ~ "utilization"
| statsby avg_utilization:avg(value), group_by(service_name)
| sort desc(avg_utilization)
```

## 📊 PERFORMANCE EXPECTATIONS

| Query Type | Data Volume | Expected Time | Use Case |
|------------|-------------|---------------|----------|
| **Dataset Discovery** | Metadata search | 200-500ms | Finding relevant data |
| **Log Queries** | 1000+ log entries | 1-3 seconds | Error investigation |
| **Metrics Queries** | 100+ data points | 500ms-2s | Performance analysis |

### When to Use Each Approach
- **Log Analysis**: Error messages, debug information, specific event investigation
- **Metrics Analysis**: Performance trends, error rates, system health monitoring
- **Hybrid**: Complex investigations requiring both frequency and context

## 🚧 COMMON ISSUES & SOLUTIONS

| Issue | Solution |
|-------|----------|
| **Field not found errors** | **CRITICAL**: Check discovery results for exact field names - never assume fields exist |
| **Empty JSON field extraction** | Use string(field."nested.key") syntax for nested fields from discovery results |
| **OPAL syntax errors** | Check syntax reference table above for verified patterns |
| **Slow query performance** | Use discovery tools first, then targeted queries |
| **Missing data** | Verify dataset schema and field names from discovery results |
| **Large result sets** | Use OPAL limit clause to control query result size |
| **Wrong dataset interface** | Check Dataset Type & Interface from discovery (log vs metric vs trace) |
