mysql-patterns
fmarzochi/egc
MySQL and MariaDB schema, query, indexing, transaction, replication, and connection-pool patterns for production backends.
mysql
sreyemnayr/database-skills
Plan and review MySQL/InnoDB schema, indexing, query tuning, transactions, and operations. Use when creating or modifying MySQL tables, indexes, or queries; diagnosing slow/locking behavior; planning migrations; or troubleshooting replication and connection issues. Load when using a MySQL database.

sqlanvil-engineering-fundamentals
sqlanvil/agent-skills
Use when writing or editing a sqlanvil data project (.sqlx models, workflow_settings.yaml, .df-credentials.json) targeting PostgreSQL, Supabase, or MySQL/MariaDB - corrects Dataform/BigQuery priors that produce wrong config blocks, credentials, DDL, separators, and CLI commands in the sqlanvil fork
oracle-to-percona
percona-lab/skills
Migrating from Oracle Database to Percona Server for MySQL. Use when porting an Oracle schema, PL/SQL, or application to Percona Server / MySQL, mapping Oracle data types, or rewriting Oracle SQL constructs. IMPORTANT - unlike MariaDB (which has sql_mode=ORACLE and PL/SQL compatibility), MySQL and Percona Server have NO Oracle compatibility mode. Oracle→Percona is a genuine schema-and-code rewrite, not a compatibility-mode switch: PL/SQL packages, ROWNUM, CONNECT BY, sequences, (+) joins, and empty-string=NULL semantics all need rewriting. Recursive CTEs and window functions require MySQL/Percona 8.0+.
mongodb-docs
cookiemonsterdev/agents-skills
Use when users ask how to deploy, connect to, query, model, index, aggregate, secure, scale, back up, monitor, or troubleshoot MongoDB databases and applications, including Atlas, Community Edition, Enterprise Advanced, CRUD, the aggregation framework, search, vector search, transactions, change streams, replication, sharding, drivers, Compass, or data modeling, especially when they need official MongoDB documentation, exact links, or docs-grounded guidance.

Run and manage accessory services — databases, Redis, search, and other long-lived dependencies your app needs — through Kamal's `accessories:` configuration and the `kamal accessory` command. Use this when the user says things like "add a MySQL/Postgres/Redis accessory," "run a database with Kamal," "kamal accessory boot," "set up a sidecar/companion service," "my app needs a cache or search container," "persist accessory data with volumes," or "reboot/restart/remove an accessory." Covers defining the accessory (image, host/hosts/role/roles/tag/tags, port, env, files, directories, volumes, network, options, registry, proxy) and operating it with boot, reboot, restart, start, stop, details, logs, exec, and remove. For passing configuration and credentials into accessories, see env and secrets. For scheduled jobs, see cron.

nodeboot-starter-persistence-mongodb
nodejs-boot/node-boot
Use when the user wants MongoDB persistence in a Node-Boot app via `@nodeboot/starter-persistence` and TypeORM's Mongo driver — `persistence.type mongodb`. Covers Mongo entity shape (`@ObjectIdColumn`/`_id`), `MongoRepository<T>`, `MongoPagingAndSortingRepository<T>` cursor-based paging, entity subscribers, and injecting `MongoClient` directly. This is the MongoDB flavour of `nodeboot-starter-persistence`; use `nodeboot-starter-persistence-sql` instead for relational databases.
mysql-problem-solver
pekral/pint-rules
Use when you need to analyze and solve MySQL performance or query design problems directly from a real codebase or database environment. Inspects SQL queries, table structure, index usage, and uses terminal tools (mysql, EXPLAIN) when possible. For pragmatic diagnosis of slow queries, joins, indexes, and filtering in existing applications.
percona-server-features
percona-lab/skills
Percona Server for MySQL features and enhancements that go beyond stock Oracle MySQL. Use when working with Percona Server, reviewing MySQL code or schema that runs on Percona Server, asking what Percona Server adds over community MySQL, tuning instrumentation/observability, configuring data-at-rest encryption, auditing, the MyRocks engine, threadpool, or backup locking. Also use when deciding whether Percona Server's extra features help a given workload. IMPORTANT - Percona Server is a TRUE drop-in binary replacement for the matching MySQL version (8.0, 8.4 LTS, 9.x): same SQL, same wire protocol, same replication. Do NOT treat it like MariaDB (which is not a drop-in). The value is extra instrumentation, encryption, and operational features bundled in - not syntax differences.
mysql-patterns
defuj/opencode-agent-kit
MySQL and MariaDB schema, query, indexing, transaction, replication, and connection-pool patterns for production backends.
11ai-mongodb-cheatsheet
rj11io/11ai

percona-operators-on-k8s
percona-lab/skills
Running Percona databases on Kubernetes with the Percona Operators - for PXC, MongoDB, PostgreSQL, and Percona Server for MySQL. Use this skill when the user writes or edits a Custom Resource (CR) for a Percona database on K8s, chooses between the two MySQL operators, configures operator-managed backups (S3/GCS/Azure) or PITR, scales a cluster, or performs a version upgrade. CRITICAL POINT - CR kinds, apiVersion groups, and field names differ per operator and shift between releases, and this is the #1 hallucination area: there are TWO MySQL operators (PXC-based vs Percona-Server-based) with separate CRDs (`pxc.percona.com` vs `ps.percona.com`); the PostgreSQL operator uses apiVersion `pgv2.percona.com/v2` (NOT `pg.percona.com`) and the field `replicas` (NOT `size`), while PXC/MongoDB/MySQL use `size`; PXC's `allowUnsafeConfigurations` is deprecated in favor of an `unsafeFlags` subsection. NEVER emit a CR field, kind, or apiVersion without verifying it against percona-dk for the operator version in use.

mongodb-expert
sayed-moin-ahmed/mongodb-expert-skill

psmdb-features
percona-lab/skills
What Percona Server for MongoDB (PSMDB) adds beyond MongoDB Community Edition, and how to configure it. Use this skill when the user asks about PSMDB hot backup, data-at-rest encryption, audit logging, LDAP/Kerberos/OIDC authentication, the in-memory storage engine, log redaction, or 'how do I get MongoDB Enterprise feature X for free'. PSMDB is a drop-in replacement for MongoDB Community that ships most MongoDB Enterprise features as open source. KEY POINT - several features are version-gated (KMIP and Kerberos since 6.0.2-1, OIDC since 7.0, OpenBao KMS in 8.0) and the Transparent Huge Pages requirement REVERSES at 8.0; agents that assume uniform behavior across 6.0/7.0/8.0 will emit wrong config. PSMDB does NOT include SNMP monitoring.
