Skills using MongoDB (217)
mongodb-natural-language-querying
Generate read-only MongoDB queries (find) or aggregation pipelines using natural language, with collection schema context and sample documents. Use this skill whenever the user asks to write, create, or generate MongoDB queries, wants to filter/query/aggregate data in MongoDB, asks "how do I query...", needs help with query syntax, or discusses finding/filtering/grouping MongoDB documents. Also use for translating SQL-like requests to MongoDB syntax. Does NOT handle Atlas Search ($search operator), vector/semantic search ($vectorSearch operator), fuzzy matching, autocomplete indexes, or relevance scoring - use search-and-ai for those. Does NOT analyze or optimize existing queries - use mongodb-query-optimizer for that. Does NOT handle aggregation pipelines that involve write operations. Requires MongoDB MCP server.

Use only when the user asks for optimization or performance: "How do I optimize this query?", "How do I index this?", "Why is this query slow?", "Can you fix my slow queries?", "What are the slow queries on my cluster?", etc. Do not invoke for general MongoDB query writing unless user asks for performance or index help. Prefer indexing as optimization strategy. Use MongoDB MCP when available.

MongoDB schema migration safety reviewer and migration script generator. ALWAYS use when writing, reviewing, or planning MongoDB schema changes — field additions/removals, index builds, schema validator changes, document type migrations, shard key modifications, or any bulk update touching production collections. Covers index build lock behavior (replicated default vs the rolling exception), additive schema evolution, batched backfills, write concern tuning during migration, reshardCollection (5.0+), collMod validator changes, and rollback planning. Use even for "just add a field" — MongoDB's schema-less nature makes silent type inconsistencies and missing-field bugs harder to detect than RDBMS constraint violations.

database-documentation
Generate grounded-and-verified, engine-agnostic database documentation that reaches 100% parity with the real schema. Introspects the LIVE database as ground truth and cross-validates it against ORM models, migrations, generated types, seeds, and application queries, then proves completeness by diffing the docs back against the database. Produces ER diagrams (mermaid), per-table data dictionaries, and a machine-readable schema.json. Works with PostgreSQL, MySQL, SQL Server, and SQLite across any ORM (Prisma, TypeORM, Drizzle, Sequelize, Knex, Django, Rails) or raw SQL. Use when asked to document a database, produce an ERD or data dictionary, write db/schema docs, audit schema drift, or refresh existing DB docs.
mir-database-mongo
Make It Right (MongoDB module). MongoDB 8.x mechanics the engine-independent pillar omits: embed vs reference decided per relationship by access pattern, cardinality, update frequency; the 16 MB BSON limit and unbounded arrays; $jsonSchema validators — a collection accepts any shape until you add one; write concern w:1 losing acknowledged writes on failover; read concern, stale secondary reads, retryable writes — updateMany/deleteMany are NOT retryable; the 60-second transaction lifetime limit vs a single-document atomic update; compound-index prefix rules, ESR ordering, covered queries; aggregation stage ordering and the 100 MB stage limit; shard-key selection — a monotonic key creates a hot shard; NoSQL operator injection. Chains: mir-database (the gates) → this. TRIGGER only when the datastore is MongoDB itself (Community, Enterprise, Atlas) — designing a collection or document schema, picking a shard key, writing an aggregation pipeline or index, or debugging a Mongo consistency, concurrency, or query-pla

Architect-grade technology decision briefs — "which option should we pick, and why?" Takes a decision question (X vs Y vs Z for a stated context: library, database, framework, platform, buy-vs-build) plus your constraints, fans out parallel sub-agents to research each option's project health, community sentiment, technical claims, and operational story, then scores options across weighted criteria and emits an ADR-style recommendation with a full scorecard and cited evidence. Keyless; the recommendation is advisory — you decide. Use when the user must choose between technologies or approaches — e.g. "/verdict postgres vs mongodb for <use case>", "should we use Kafka or NATS", "compare X and Y", "buy vs build", "which framework for this". Also supports "/verdict revisit <brief>" to cheaply re-check a past verdict's revisit-when triggers.
