Use this skill whenever the user mentions MongoDB queries, wants to search/filter/aggregate data in MongoDB, asks "how do I query...", needs help with query syntax, wants to optimize a query, or discusses finding/filtering/grouping MongoDB documents - even if they don't explicitly say "generate a query".

Requires MongoDB MCP server. +allowed-tools: mcp__mongodb__*, Read, Bash +--- + +# MongoDB Query Generation + +You are an expert MongoDB query generator. When a user requests a MongoDB query or aggregation pipeline, follow these guidelines based on the Compass query generation patterns. + +## Query Generation Process + +### 1. Gather Context Using MCP Tools + +**Required Information:** +- Database name and collection name (use `mcp__mongodb__list-databases` and `mcp__mongodb__list-collections` if not provided) +- User's natural language description of the query +- Current date context: ${currentDate} (for date-relative queries) + +**Fetch in this order:** + +1. **Indexes** (for query optimization): + ``` + mcp__mongodb__collection-indexes({ database, collection }) + ``` + +2. **Schema** (for field validation): + ``` + mcp__mongodb__collection-schema({ database, collection, sampleSize: 50 }) + ``` + - Returns flattened schema with field names and types + - Includes nested document structures and array fields + +3. **Sample documents** (for understanding data patterns): + ``` + mcp__mongodb__find({ database, collection, limit: 4 }) + ``` + - Shows actual data values and formats + - Reveals common patterns (enums, ranges, etc.) + +### 2. Analyze Context and Validate Fields + +Before generating a query, always validate field names against the schema you fetched. MongoDB won't error on nonexistent field names - it will simply return no results or behave unexpectedly, making bugs hard to diagnose. By checking the schema first, you catch these issues before the user tries to run the query. + +Also review the available indexes to understand which query patterns will perform best. + +### 3. Choose Query Type: Find vs Aggregation + +Prefer find queries over aggregation pipelines because find queries are simpler, faster, and easier for other developers to understand. Find queries also have better performance characteristics for simple filtering and sorting since they avoid the aggregation framework overhead. + +**For Find Queries**, generate responses with these fields: +- `filter` - The query filter (required) +- `project` - Field projection (optional) +- `sort` - Sort specification (optional) +- `skip` - Number of documents to skip (optional) +- `limit` - Number of documents to return (optional) +- `collation` - Collation specification (optional) + +**Use Find Query when:** +- Simple filtering on one or more fields +- Basic sorting and limiting +- Field projection only +- No data transformation needed + +**For Aggregation Pipelines**, generate an array of stage objects. + +**Use Aggregation Pipeline when the request requires:** +- Grouping or aggregation functions (sum, count, average, etc.) +- Multiple transformation stages +- Computed fields or data reshaping +- Joins with other collections ($lookup) +- Array unwinding or complex array operations +- Text search with scoring + +### 4. Format Your Response + +Always output queries as **valid JSON strings**, not JavaScript objects. This format allows users to easily copy/paste the queries and is compatible with the MongoDB MCP server tools. + +**Find Query Response:** +```json +{ + "query": { + "filter": "{ age: { $gte: 25 } }", + "project": "{ name: 1, age: 1, _id: 0 }", + "sort": "{ age: -1 }", + "limit": "10" + } +} +``` + +**Aggregation Pipeline Response:** +```json +{ + "aggregation": { + "pipeline": "[{ $match: { status: 'active' } }, { $group: { _id: '$category', total: { $sum: '$amount' } } }]" + } +} +``` + +Note the stringified format: +- ✅ `"{ age: { $gte: 25 } }"` (string) +- ❌ `{ age: { $gte: 25 } }` (object) + +For aggregation pipelines: +- ✅ `"[{ $match: { status: 'active' } }]"` (string) +- ❌ `[{ $match: { status: 'active' } }]` (array) + +## Best Practices + +### Query Quality +1. **Use indexes efficiently** - Structure filters to leverage available indexes: + - Check collection indexes before generating the query + - Order filter fields to match index key order when possible + - Use equality matches before range queries (matches index prefix behavior) + - Avoid operators that prevent index usage: `$where`, `$text` without text index, `$ne`, `$nin` (use sparingly) + - For compound indexes, use leftmost prefix when possible + - If no relevant index exists, mention this in your response (user may want to create one) +2. **Project only needed fields** - Reduce data transfer with projections +3. **Validate field names** against the schema before using them +4. **Handle edge cases** - Consider null values, missing fields, type mismatches +5. **Use appropriate operators** - Choose the right MongoDB operator for the task: + - `$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte` for comparisons + - `$in`, `$nin` for membership tests + - `$and`, `$or`, `$not`, `$nor` for logical operations + - `$regex` for text pattern matching + - `$exists` for field existence checks + - `$type` for type validation + +### Aggregation Pipeline Quality +1. **Filter early** - Use `$match` as early as possible to reduce documents +2. **Project early** - Use `$project` to reduce field set before expensive operations +3. **Limit when possible** - Add `$limit` after `$sort` when appropriate +4. **Use indexes** - Ensure `$match` and `$sort` stages can use indexes: + - Place `$match` stages at the beginning of the pipeline + - Initial `$match` and `$sort` stages can use indexes if they precede any stage that modifies documents + - Structure `$match` filters to align with available indexes + - Avoid `$project`, `$unwind`, or other transformations before `$match` when possible +5. **Optimize `$lookup`** - Consider denormalization for frequently joined data +6. **Group efficiently** - Use accumulators appropriately: `$sum`, `$avg`, `$min`, `$max`, `$push`, `$addToSet` + +### Error Prevention +1. **Validate all field references** against the schema +2. **Quote field names correctly** - Use dot notation for nested fields +3. **Handle array fields properly** - Use `$elemMatch`, `$size`, `$all` as needed +4. **Escape special characters** in regex patterns +5. **Check data types** - Ensure operations match field types from schema +6. **Geospatial coordinates** - MongoDB's GeoJSON format requires longitude first, then latitude (e.g., `[longitude, latitude]` or `{type: "Point", coordinates: [lng, lat]}`). This is opposite to how coordinates are often written in plain English, so double-check this when generating geo queries. + +## Schema Analysis + +When provided with sample documents, analyze: +1. **Field types** - String, Number, Boolean, Date, ObjectId, Array, Object +2. **Field patterns** - Required vs optional fields (check multiple samples) +3. **Nested structures** - Objects within objects, arrays of objects +4. **Array elements** - Homogeneous vs heterogeneous arrays +5. **Special types** - Dates, ObjectIds, Binary data, GeoJSON + +## Sample Document Usage + +Use sample documents to: +- Understand actual data values and ranges +- Identify field naming conventions (camelCase, snake_case, etc.) +- Detect common patterns (e.g., status enums, category values) +- Estimate cardinality for grouping operations +- Validate that your query will work with real data + +## Common Pitfalls to Avoid + +1. **Using nonexistent field names** - Always validate against schema first. MongoDB won't error; it just returns no results. +2. **Wrong coordinate order** - GeoJSON uses [longitude, latitude], not [latitude, longitude]. +3. **Choosing aggregation when find suffices** - Aggregation adds overhead; use find for simple queries. +4. **Missing index awareness** - Structure queries to leverage indexes. If no index exists for key filters, mention this to the user. +5. **Type mismatches** - Check schema to ensure operators match field types (e.g., don't use `$gt` on strings when comparing alphabetically). + +## Error Handling + +If you cannot generate a query: +1. **Explain why** - Missing schema, ambiguous request, impossible query +2. **Ask for clarification** - Request more details about requirements +3. **Suggest alternatives** - Propose different approaches if available +4. **Provide examples** - Show similar queries that could work + +## Example Workflow + +**User Input:** "Find all active users over 25 years old, sorted by registration date" + +**Your Process:** +1. Check schema for fields: `status`, `age`, `registrationDate` or similar +2. Verify field types match the query requirements +3.

+1. **Text Search:** Should prefer Atlas Search ($search) over $regex for text matching when appropriate + - Current: Uses $regex with case-insensitive flag + - Recommended: Use aggregation with $search stage for full-text search capabilities + - Impact: Missing relevance scoring and advanced text search features + +**Performance Notes:** +- Skill consistently recommends index creation when no relevant indexes exist +- Properly structures queries to leverage indexes when available +- Places $match early in aggregation pipelines for optimal performance + +**Format Compliance:** +- ✅ All queries properly formatted as JSON strings +- ✅ Consistent use of single quotes in MongoDB queries +- ✅ Proper escaping and quoting throughout + +## Recommendations for Skill Improvement + +1. **Add Atlas Search Support** + - Detect when text search is needed + - Prefer $search over $regex for substring matching + - Include example of $search syntax in skill documentation + +2. **Consider Adding Assertions to evals.json** + - Current evals lack programmatic assertions + - Would enable automated scoring + - See eval_metadata.json files for assertion examples + +3. **Minor Wording Improvements** + - Current skill performs excellently + - Consider adding guidance on when to use $regex vs $search diff --git a/skills/mongodb-query/mongodb-query-workspace/load-fixtures.js

Sep 17 00:00:00 2001 From: "elizabeth.button" Date: Wed, 4 Mar 2026 12:15:36 -0500 Subject: [PATCH 02/25] Reorganize mongodb-query skill to pass skill-validator Moved test infrastructure (evals/ and mongodb-query-workspace/) outside the skill directory to testing/mongodb-query/. Skills should only contain essential files that agents need; test fixtures, evaluation cases, and benchmarks are development/CI artifacts that don't belong in the skill package. The skill now passes skill-validator check with: - Clean structure (SKILL.md only) - 2,259 tokens (within recommended limits) - No validation errors or warnings Co-Authored-By: Claude Sonnet 4.5 ---

-**Format Compliance:** -- ✅ All queries properly formatted as JSON strings -- ✅ Consistent use of single quotes in MongoDB queries -- ✅ Proper escaping and quoting throughout - -## Recommendations for Skill Improvement - -1. **Add Atlas Search Support** - - Detect when text search is needed - - Prefer $search over $regex for substring matching - - Include example of $search syntax in skill documentation - -2. **Consider Adding Assertions to evals.json** -
