Use when you need to implement or improve Java logging and observability — including selecting SLF4J with Logback/Log4j2, applying proper log levels (ERROR, WARN, INFO, DEBUG, TRACE), parameterized logging, secure logging without sensitive data exposure, environment-specific configuration, log aggregation and monitoring, or validating logging through tests. This should trigger for requests such as Improve logging; Apply logging; Refactor logging; Add logging support. Part of cursor-rules-java project
Use when creating a plan using Plan model and enhancing structured design plans in Cursor Plan mode for Java implementations. Use when the user wants to create a plan, design an implementation, structure a development plan, or use plan mode for outside-in TDD, feature implementation, or refactoring work. This should trigger for requests such as Create a plan with Cursor Plan mode; Write a plan with Claude Plan mode; Design an implementation plan; Structure a development plan.

Query database safely with parameterized statements
Secures webhook receivers with signature verification, retry handling, deduplication, idempotency keys, and error responses. Provides verification code, dedupe storage strategy, runbook for incidents. Use when implementing "webhooks", "webhook security", "event receivers", or "third-party integrations".
Apply when designing or implementing HTTP endpoints exposed by a VTEX IO backend service. Covers route boundaries, handler structure, middleware composition, request validation, and response modeling for service.json routes. Use for webhook endpoints, partner integrations, callback APIs, or reviewing VTEX IO handlers that should expose explicit HTTP contracts.
ADO.NET patterns, Entity Framework, database best practices
Example of a properly self-contained skill following all best practices
Use when writing new Rails code for a project using the PostgreSQL + Hotwire + Tailwind CSS stack. Covers stack-specific patterns only: MVC structure, ActiveRecord query conventions, Turbo Frames/Streams wiring, Stimulus controllers, and Tailwind component patterns. Not for general Rails design principles — this skill is scoped to what changes based on this specific technology stack.
nginx C module development guidelines based on the official nginx development guide. This skill should be used when writing, reviewing, or refactoring nginx C modules to ensure correct memory management, request lifecycle handling, and event-driven patterns. Triggers on tasks involving nginx module development, ngx_http_module_t, handler/filter/upstream implementation, pool allocation, or nginx configuration directives.
Build USDC bridging with Circle Bridge Kit SDK and Crosschain Transfer Protocol (CCTP). Supports bridging USDC between EVM chains, between EVM chains and Solana, and between any two chains on Circle Wallets (i.e Developer-Controlled Wallets or Programmable wallets). Use when: bridge USDC, setting up Bridge Kit adapters (Viem, Ethers, Solana Kit, Circle Wallets), handling bridge events, collecting custom fees, configuring transfer speed, or using the Forwarding Service. Triggers on: Bridge Kit, bridge USDC, crosschain transfer, CCTP, move USDC between chains, @circle-fin/bridge-kit, adapter-viem, adapter-ethers, adapter-solana-kit, forwarding service, bridge routes.
Temenos T24 Transact integration. Manage data, records, and automate workflows. Use when the user wants to interact with Temenos T24 Transact data.
Guide REST API integration including HTTP methods, authentication, error handling, and rate limiting. Use this skill when the user needs to connect to a third-party API, design an API client, troubleshoot API errors, or understand API concepts — even if they say 'connect to this API', 'why is the API returning errors', 'how do I authenticate', or 'build an API integration'.
