Implement sophisticated rate limiting with sliding windows, token buckets, and quotas. Use when protecting APIs from excessive requests. Trigger with phrases like "add rate limiting", "limit API requests", or "implement rate limits".
Defines REST endpoints using Minimal APIs with OpenAPI documentation via Scalar. Use when: Creating or modifying API endpoints in Sorcha services, adding new routes, configuring endpoint authentication, or documenting APIs.
PHP 8.x modernization patterns. Use when upgrading to PHP 8.2/8.3/8.4, implementing type safety, or achieving PHPStan level 10.
Master FastAPI dependency injection for building modular, testable APIs. Use when creating reusable dependencies and services.
Turso (Limbo) database helper — an in-process SQLite-compatible database written in Rust. Formerly known as libSQL / libsql. Replaces @libsql/client, libsql-experimental for Turso use cases. Works in Node.js, browser (WASM + OPFS for persistent local storage), React Native, and server-side. Features: vector search, full-text search, CDC, MVCC, encryption, remote sync. SDKs: JavaScript (@tursodatabase/database), Browser/WASM (@tursodatabase/database-wasm), React Native (@tursodatabase/sync-react-native), Rust (turso), Python (pyturso), Go (tursogo). This skill contains all SDK documentation needed to use Turso — do NOT search the web for Turso/libsql docs.
Design contingency module architectures for failure scenarios.
.NET Core and ASP.NET Core architecture guidance for building secure, scalable backend services. Covers solution structure, dependency injection, middleware, data access, security, performance, and deployment.
Ruby on Rails integration for Unpoly. Use when working with the unpoly-rails gem or building Unpoly-powered Rails apps. Covers server-side helpers (up?, up.target, up.layer.accept, up.layer.dismiss, up.layer.open, up.validate?, up.cache.expire, up.context, up.emit, up.safe_callback, fresh_when, render_nothing), Rails view helpers (link_to, form_with, button_to with Unpoly attributes), flash messages with [up-hungry], Turbo coexistence (disabling Turbo Drive in Rails 7+), CSP setup with csp_meta_tag, and global follow-all config.
Best practices for developing, deploying, and debugging Supabase Edge Functions (Deno runtime). Use when working with Edge Functions for tasks like ingest pipelines, webhooks, scheduled jobs, or database triggers. Covers authentication patterns (service role vs anon key), error debugging, database integration, and common pitfalls.
Work with the Memberstack Admin API to manage members, plans, and data tables. Use this skill whenever the user mentions Memberstack, member management via API, Memberstack data tables, or wants to build integrations that create/read/update/delete members or data records in Memberstack. Also trigger when the user asks about Memberstack API endpoints, authentication, pagination, querying records, or connecting plans to members — even if they don't say "Memberstack" explicitly but reference concepts like plan connections, member metadata, or admin member APIs that align with Memberstack's domain.
Guide feature development for full-stack applications with architecture focus. Covers Next.js App Router patterns, NestJS backend services, database models, data workflows, and seamless integration. Use when adding new features, refactoring existing code, or planning major changes.
Guide for adding new environment variables to the codebase. Ensures env.ts schemas include descriptions and .env.example is kept in sync. Triggers on: add env variable, new environment variable, env.ts change, add config variable, INKEEP_, adding to .env.
