pgx-cli
jyasuu/pg_x
Use this skill whenever the user wants to use, configure, or troubleshoot pgx (also called pg_x) — the Rust "PostgreSQL Power CLI" — for running queries, exporting data, streaming NOTIFY events, streaming WAL via logical replication, composing GraphQL over SQL resolvers, or running it as an MCP server. Trigger on mentions of pgx/pg_x, PostgreSQL logical replication CLI, `pgx replicate`, `pgx listen`, `pgx consume`, `pgx graphql`, `pgx mcp`, WAL-to-Kafka/RabbitMQ/Elasticsearch/Parquet pipelines, NOTIFY-to-downstream forwarding, or `~/.pgx/config.toml`. Covers every downstream sink (stdout, shell, webhook, RabbitMQ, Kafka, Parquet, Postgres, Elasticsearch, KV/Redis/Memcached) and how to wire data from Postgres to each one, both via CLI flags and via config-file profiles.

graphql
iam-nazmul/drcr
This skill should be used when working with GraphQL in this project — writing or reviewing a schema.py/.graphql file, defining Strawberry types (`@strawberry.type`, `@strawberry.input`), writing resolvers or mutations, deciding whether a new endpoint should be GraphQL or REST, or diagnosing GraphQL-specific problems like the N+1 query problem, DataLoader batching, query depth/complexity limits, or field-level permissions. Applies to Strawberry (strawberry-graphql) and strawberry-django as the current recommended Python GraphQL stack for Django — not graphene-django, which is the older, less actively recommended alternative.

graphql
andrewhaward2310/.agents
GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully.

grpc-streaming-test-author
testland/qa
Workflow-driven skill that builds gRPC streaming-RPC test suites from a proto definition. Classifies each RPC by pattern (unary, server-streaming, client-streaming, bidi), then emits the required categories per pattern - ordering preservation, completion semantics (server close after stream end, client half-close), cancellation, deadline handling, partial-stream failure. Produces skeletons for Go (bufconn + Send/Recv), Python (iterators), JVM (StreamObserver), Node (call.write/end). Use when adding tests for a new streaming RPC or auditing a suite for uncovered categories. Different test surface from grpc-interceptor-test-author (interceptor layer) and grpc-mock (harness); for wire-level streaming semantics use grpc-streaming-tests, not this.
graphql-architect

Cover deadline + cancellation + flow control + status codes (CANCELLED, DEADLINE_EXCEEDED) + metadata. Use ghz for load, grpcurl for ad-hoc, language-native test stubs for unit/integration. Use when a service exposes server-, client-, or bidirectional-streaming RPCs and deadline, cancellation, or partial-stream status-code behavior is unverified.
