### CONTEXT
{context}

### CRITICAL INSTRUCTION
Return ONLY the MongoDB query filter as valid JSON. Do not include any explanations, markdown formatting, comments, or additional text. Just the raw JSON object that can be used directly in a MongoDB find() operation.

### FILTER GUIDELINES
1. **Syntax**: Use MongoDB query operators and proper JSON syntax
2. **Performance**: Consider indexing and query optimization
3. **Security**: Use safe query patterns, avoid NoSQL injection risks
4. **Data Types**: Use appropriate MongoDB data types (ObjectId, Date, etc.)
5. **Efficiency**: Structure filters for optimal query execution

### MONGODB QUERY OPERATORS

**Comparison Operators**:
- **$eq**: Equals - \`{"status": {"$eq": "active"}}\` or \`{"status": "active"}\`
- **$ne**: Not equals - \`{"status": {"$ne": "inactive"}}\`
- **$gt**: Greater than - \`{"age": {"$gt": 18}}\`
- **$gte**: Greater than or equal - \`{"price": {"$gte": 100}}\`
- **$lt**: Less than - \`{"score": {"$lt": 90}}\`
- **$lte**: Less than or equal - \`{"rating": {"$lte": 5}}\`
- **$in**: In array - \`{"category": {"$in": ["tech", "science"]}}\`
- **$nin**: Not in array - \`{"status": {"$nin": ["deleted", "banned"]}}\`

**Logical Operators**:
- **$and**: AND condition - \`{"$and": [{"age": {"$gte": 18}}, {"status": "active"}]}\`
- **$or**: OR condition - \`{"$or": [{"status": "active"}, {"status": "pending"}]}\`
- **$not**: NOT condition - \`{"age": {"$not": {"$lt": 18}}}\`
- **$nor**: NOR condition - \`{"$nor": [{"status": "deleted"}, {"verified": false}]}\`

**Element Operators**:
- **$exists**: Field exists - \`{"email": {"$exists": true}}\`
- **$type**: Field type - \`{"count": {"$type": "number"}}\`

**Array Operators**:
- **$all**: All elements match - \`{"tags": {"$all": ["tech", "mongodb"]}}\`
- **$elemMatch**: Element matches - \`{"scores": {"$elemMatch": {"$gte": 80, "$lt": 90}}}\`
- **$size**: Array size - \`{"items": {"$size": 3}}\`

**String Operators**:
- **$regex**: Regular expression - \`{"name": {"$regex": "^John", "$options": "i"}}\`
- **$text**: Text search - \`{"$text": {"$search": "mongodb tutorial"}}\`

### EXAMPLES

**Simple equality**: "Find active users"
→ {"status": "active"}

**By ObjectId**: "Find document by ID"
→ {"_id": ObjectId("507f1f77bcf86cd799439011")}

**Range query**: "Find products between $10 and $100"
→ {"price": {"$gte": 10, "$lte": 100}}

**Multiple conditions**: "Find active premium users"
→ {"status": "active", "plan": "premium"}

**OR condition**: "Find active or pending orders"
→ {"$or": [{"status": "active"}, {"status": "pending"}]}

**Array contains**: "Find users with admin role"
→ {"roles": {"$in": ["admin"]}}

**Text search**: "Find posts containing 'mongodb'"
→ {"$text": {"$search": "mongodb"}}

**Date range**: "Find recent posts (last 30 days)"
→ {"createdAt": {"$gte": {"$date": "2024-01-01T00:00:00.000Z"}}}

**Nested object**: "Find users in New York"
→ {"address.city": "New York"}

**Field exists**: "Find users with email addresses"
→ {"email": {"$exists": true, "$ne": null}}

**Complex AND/OR**: "Find active users who are either premium or have high score"
→ {"$and": [{"status": "active"}, {"$or": [{"plan": "premium"}, {"score": {"$gte": 90}}]}]}

**Array matching**: "Find posts with specific tags"
→ {"tags": {"$all": ["javascript", "tutorial"]}}

**Regex pattern**: "Find users with Gmail addresses"
→ {"email": {"$regex": "@gmail\\.com$", "$options": "i"}}

**Size check**: "Find users with exactly 3 hobbies"
→ {"hobbies": {"$size": 3}}

**Null/undefined check**: "Find incomplete profiles"
→ {"$or": [{"profile": null}, {"profile": {"$exists": false}}]}

### SECURITY CONSIDERATIONS
- Avoid directly embedding user input without validation
- Use proper data types (ObjectId for IDs, dates for timestamps)
- Consider query performance and indexing
- Be cautious with regex patterns that could cause performance issues
- Validate that field names exist in your schema

### PERFORMANCE TIPS
- Structure filters to use indexed fields first
- Use specific equality matches when possible
- Avoid complex regex patterns on large collections
- Consider using compound indexes for multi-field queries
- Use $limit in combination with filters for large result sets

### CONTEXT
{context}

### CRITICAL INSTRUCTION
Return ONLY the aggregation pipeline as a valid JSON array. Do not include any explanations, markdown formatting, comments, or additional text. Just the raw JSON array.

### PIPELINE GUIDELINES
1. **Structure**: Always return a JSON array of aggregation stages
2. **Performance**: Order stages efficiently - use $match and $limit early when possible
3. **Security**: Avoid unsafe operations or overly complex expressions
4. **Readability**: Use clear field names and logical stage ordering
5. **Data Types**: Handle ObjectId, dates, numbers, and nested objects correctly

### AGGREGATION STAGES
**Filtering & Matching:**
- $match: Filter documents (use early in pipeline)
- $lookup: Join collections
- $facet: Multi-faceted aggregations

**Grouping & Analysis:**

      "inventoryCount": 1
    }},
    {"$sort": {"distance": 1}},
    {"$limit": 5}
  ]

### PERFORMANCE TIPS
- Place $match as early as possible to reduce document flow
- Use $limit after $sort for top-N queries  
- Index fields used in $match, $sort, and $lookup operations
- Use $project to reduce document size in multi-stage pipelines
- Consider $facet for multiple aggregations on same data

### SECURITY CONSIDERATIONS
- Validate input parameters to prevent injection
- Use appropriate read concerns for consistency requirements
- Be cautious with $where and $expr in $match stages
- Limit pipeline complexity to prevent timeout/resource issues

### UPDATE FILTER GUIDELINES
1. **Precision**: Use specific criteria to target exact documents you want to update
2. **Safety**: Avoid broad filters that might update unintended documents
3. **Uniqueness**: When possible, use unique identifiers like _id or email
4. **Verification**: Consider what happens if multiple documents match your filter

**Element Operators**:
- **$exists**: Field exists - \`{"email": {"$exists": true}}\`
- **$type**: Field type - \`{"count": {"$type": "number"}}\`

### UPDATE FILTER EXAMPLES

**By unique ID**: "Update specific document by ID"
→ {"_id": ObjectId("507f1f77bcf86cd799439011")}

**By unique email**: "Update user with specific email"
→ {"email": "john.doe@example.com"}

**By username**: "Update user account by username"
→ {"username": "johndoe"}

**Multiple specific criteria**: "Update active users in sales department"
→ {"status": "active", "department": "sales"}

**Conditional update**: "Update expired premium accounts"
→ {"plan": "premium", "expiryDate": {"$lt": {"$date": "2024-01-01T00:00:00.000Z"}}}

**Status-based update**: "Update all pending orders"
→ {"status": "pending"}

**Range-based update**: "Update products with low stock"
→ {"stock": {"$lt": 10}, "active": true}

**Complex condition**: "Update users who haven't logged in recently"
→ {"$and": [{"status": "active"}, {"lastLogin": {"$lt": {"$date": "2023-12-01T00:00:00.000Z"}}}]}

### SAFETY CONSIDERATIONS FOR UPDATES
- **Always test your filter first** with a find() operation to see what documents match
- **Use unique identifiers** when updating single documents (_id, email, username)
- **Be specific** - avoid filters that might match more documents than intended
- **Consider using $and** to combine multiple conditions for precision
- **Validate field names** exist in your schema before updating

### SAFETY CONSIDERATIONS
- ALWAYS use atomic operators ($set, $unset, $inc, etc.) - never provide raw field assignments
- For destructive operations like $unset or array modifications, ensure the request is intentional
- Consider data types when setting values (strings, numbers, booleans, dates, ObjectIds)
- Use $addToSet instead of $push to prevent duplicate array elements when appropriate
- Validate that increment operations use numeric values

### MONGODB UPDATE OPERATORS & EXAMPLES

#### Field Update Operators:
- $set (update/create fields): {"$set": {"name": "John Doe", "email": "john@example.com", "lastLogin": new Date()}}
- $unset (remove fields): {"$unset": {"temporaryField": "", "deprecatedData": ""}}
- $inc (increment numbers): {"$inc": {"views": 1, "score": -5, "balance": 100.50}}
- $mul (multiply values): {"$mul": {"price": 0.9, "quantity": 2}}
- $min (update if smaller): {"$min": {"lowestScore": 85}}
- $max (update if larger): {"$max": {"highestScore": 95}}
- $currentDate (set current date): {"$currentDate": {"lastModified": true, "timestamp": {"$type": "date"}}}
- $rename (rename fields): {"$rename": {"old_name": "new_name", "temp_field": "permanent_field"}}

#### Array Update Operators:
- $push (add element): {"$push": {"tags": "new-tag", "comments": {"user": "john", "text": "Great post!"}}}
- $push with $each (add multiple): {"$push": {"tags": {"$each": ["tag1", "tag2", "tag3"]}}}
- $push with $position: {"$push": {"items": {"$each": ["new-item"], "$position": 0}}}
- $push with $slice: {"$push": {"recent_activity": {"$each": [{"action": "login"}], "$slice": -10}}}
- $addToSet (add unique): {"$addToSet": {"tags": "unique-tag", "categories": {"$each": ["cat1", "cat2"]}}}
- $pull (remove matching): {"$pull": {"tags": "unwanted-tag", "items": {"status": "deleted"}}}
- $pullAll (remove multiple): {"$pullAll": {"tags": ["tag1", "tag2"], "numbers": [1, 3, 5]}}
- $pop (remove first/last): {"$pop": {"queue": -1, "stack": 1}}

#### Array Element Updates:
- Positional $ operator: {"$set": {"comments.$.approved": true, "items.$.quantity": 5}}
- Array filters $[]: {"$set": {"items.$[elem].status": "active"}}, arrayFilters: [{"elem.category": "electronics"}]
- Multiple positional $[]: {"$inc": {"items.$[item].reviews.$[review].helpful": 1}}

#### Complex Combinations:
- Multiple operations: {"$set": {"name": "Updated Name", "status": "active"}, "$inc": {"version": 1}, "$push": {"history": {"action": "updated", "date": new Date()}}}
- Nested field updates: {"$set": {"profile.settings.notifications": true, "profile.lastSeen": new Date()}}
- Conditional updates with $cond in aggregation: {"$set": {"discount": {"$cond": [{"$gte": ["$orderAmount", 100]}, 0.1, 0]}}}

#### Data Type Examples:
- String: {"$set": {"name": "John Doe", "status": "active"}}
- Number: {"$set": {"age": 25, "score": 87.5}, "$inc": {"points": 100}}
- Boolean: {"$set": {"isActive": true, "verified": false}}
- Date: {"$set": {"createdAt": new Date("2024-01-01"), "updatedAt": new Date()}}
- ObjectId: {"$set": {"userId": ObjectId("507f1f77bcf86cd799439011")}}
- Array: {"$set": {"tags": ["mongodb", "database", "nosql"]}}
- Object: {"$set": {"metadata": {"source": "api", "version": "1.2", "processed": true}}}

### IMPORTANT FORMATTING RULES:
1. Return ONLY valid JSON - no explanations, comments, or markdown formatting
2. Use proper MongoDB update operator syntax
3. Ensure all string values are properly quoted
4. Use appropriate data types (new Date() for dates, ObjectId() for IDs)
5. For array operations, consider whether $addToSet (unique) or $push (allows duplicates) is appropriate
6. When incrementing, ensure the value is numeric
7. Structure complex nested updates clearly
8. Always validate that field paths exist in your data model

### REFERENCE VARIABLES:
You have access to workflow context variables:
- Input parameters: Use <paramName> syntax (e.g., <userId>, <newStatus>)
- Environment variables: Use {{ENV_VAR}} syntax (e.g., {{DEFAULT_STATUS}})
- Previous block outputs: Use <block.previousBlock.output.field> syntax

### CONTEXT
{context}

### CRITICAL INSTRUCTION
Return ONLY the MongoDB query filter as valid JSON. Do not include any explanations, markdown formatting, comments, or additional text. Just the raw JSON object that will identify which documents to delete.

### ⚠️ DELETION SAFETY WARNING ⚠️
DELETIONS ARE PERMANENT! This filter will determine which documents are permanently removed from the database. Be extremely careful and specific with your criteria.

### DELETE FILTER GUIDELINES
1. **EXTREME PRECISION**: Use the most specific criteria possible to target exact documents
2. **UNIQUE IDENTIFIERS**: Prefer using unique fields like _id, email, or username
3. **TEST FIRST**: Always test with find() before deleting to verify what matches
4. **BACKUP**: Consider backing up data before bulk deletions
5. **VALIDATION**: Double-check that your filter criteria are correct

### MONGODB QUERY OPERATORS

**Comparison Operators**:
- **$eq**: Equals - \`{"status": {"$eq": "inactive"}}\` or \`{"status": "inactive"}\`
- **$ne**: Not equals - \`{"status": {"$ne": "active"}}\`
- **$gt**: Greater than - \`{"age": {"$gt": 65}}\`
- **$gte**: Greater than or equal - \`{"createdAt": {"$gte": {"$date": "2024-01-01T00:00:00.000Z"}}}\`
- **$lt**: Less than - \`{"lastLogin": {"$lt": {"$date": "2023-01-01T00:00:00.000Z"}}}\`
- **$lte**: Less than or equal - \`{"score": {"$lte": 0}}\`
- **$in**: In array - \`{"status": {"$in": ["deleted", "banned", "inactive"]}}\`
- **$nin**: Not in array - \`{"type": {"$nin": ["admin", "moderator"]}}\`

**Logical Operators**:
- **$and**: AND condition - \`{"$and": [{"status": "inactive"}, {"lastLogin": {"$lt": {"$date": "2023-01-01T00:00:00.000Z"}}}]}\`
- **$or**: OR condition - \`{"$or": [{"status": "deleted"}, {"status": "banned"}]}\`
- **$not**: NOT condition - \`{"status": {"$not": {"$eq": "active"}}}\`

**Element Operators**:
- **$exists**: Field exists - \`{"deletedAt": {"$exists": true}}\`
- **$type**: Field type - \`{"tempData": {"$type": "null"}}\`

### DELETE FILTER EXAMPLES

**By unique ID**: "Delete specific document by ID"
→ {"_id": ObjectId("507f1f77bcf86cd799439011")}

**By unique email**: "Delete specific user account"
→ {"email": "user.to.delete@example.com"}

**By inactive status**: "Delete inactive user accounts"
→ {"status": "inactive"}

**By deletion flag**: "Delete documents marked for deletion"
→ {"markedForDeletion": true}

**Old temporary data**: "Delete temporary data older than 30 days"
→ {"type": "temp", "createdAt": {"$lt": {"$date": "2023-12-01T00:00:00.000Z"}}}

**Expired sessions**: "Delete expired user sessions"
→ {"type": "session", "expiresAt": {"$lt": {"$date": "2024-01-01T00:00:00.000Z"}}}

**Banned users**: "Delete banned user accounts"
→ {"status": "banned", "bannedAt": {"$exists": true}}

**Multiple criteria**: "Delete inactive accounts with no recent activity"
→ {"$and": [{"status": "inactive"}, {"lastLogin": {"$lt": {"$date": "2023-06-01T00:00:00.000Z"}}}, {"verified": false}]}

**By category**: "Delete draft posts older than 90 days"
→ {"status": "draft", "createdAt": {"$lt": {"$date": "2023-10-01T00:00:00.000Z"}}}

### EXTREME SAFETY CONSIDERATIONS FOR DELETIONS
- **⚠️ ALWAYS TEST YOUR FILTER FIRST** with db.collection.find(filter) to see exactly what will be deleted
- **Use the most specific criteria possible** - prefer unique identifiers
- **Consider soft deletion** (marking as deleted) instead of hard deletion
- **Backup important data** before performing bulk deletions
- **Avoid broad filters** that might delete more than intended
- **Validate field names** exist in your schema
- **Document your deletion criteria** for audit purposes
- **Consider the impact** on related data and foreign keys

### REMEMBER
Return ONLY the MongoDB query filter as valid JSON - no explanations, no markdown, no extra text. This filter will PERMANENTLY DELETE documents, so be extremely careful and precise!`,
