Rules and guidelines for working with Spring Data JPA in the project. ALWAYS use this skill when adding, removing, or modifying JPA entities, repositories, or projections. Trigger on any request that involves changing entity structure, adding new entities, modifying field annotations, updating database mappings, creating or modifying Spring Data repositories, or defining query projections (interfaces, DTOs).

Inspect Sentry issues, summarize production errors, and pull health data via the Sentry API (read-only). Use when user says "check Sentry", "what errors in production?", "summarize Sentry issues", "recent crashes", or "production error report". Requires SENTRY_AUTH_TOKEN. Do NOT use for setting up Sentry SDK, configuring alerts, or non-Sentry error monitoring.

Behavioral guidelines to reduce common LLM coding mistakes. Use when writing, modifying, or reviewing code — implementation tasks, code changes, refactoring, bug fixes, or feature development. Do NOT use for architecture design, documentation, or non-code tasks.

Guide for creating AI subagents with isolated context for complex multi-step workflows. Use when users want to create a subagent, specialized agent, verifier, debugger, or orchestrator that requires isolated context and deep specialization. Works with any agent that supports subagent delegation. Triggers on "create subagent", "new agent", "specialized assistant", "create verifier". Do NOT use for Cursor-specific subagents (use cursor-subagent-creator instead).

Your pathfinder for navigating unknown codebases. Investigates with precision, implements surgically, and never assumes — if it doesn't know, it says so. Maintains a .notebook/ knowledge base that grows across sessions, turning every discovery into lasting intelligence. Summons available skills, MCPs, and docs when the mission demands. Use when fixing bugs, implementing features, refactoring, investigating flows, or any development task in unfamiliar territory. Triggers on "fix this", "implement this", "how does this work", "investigate this flow", "help me with this code". Do NOT use for greenfield scaffolding, CI/CD, or infrastructure provisioning.

This skill enables Claude to track and optimize application response times. It uses the response-time-tracker plugin to monitor API endpoints, database queries, external service calls, frontend rendering, and background job execution. The plugin calculates P50, P95, and P99 percentiles, average and maximum response times. Use this skill when you need to identify performance bottlenecks, monitor SLOs, or receive alerts about performance degradation. Trigger this skill with phrases like "track response times", "optimize latency", or "monitor application performance".

This skill automates the setup of distributed tracing for microservices. It helps developers implement end-to-end request visibility by configuring context propagation, span creation, trace collection, and analysis. Use this skill when the user requests to set up distributed tracing, implement observability, or troubleshoot performance issues in a microservices architecture. The skill is triggered by phrases such as "setup tracing", "implement distributed tracing", "configure opentelemetry", or "add observability to microservices".

Enables Claude to manage Sugar's autonomous development workflows. It allows Claude to create tasks, view the status of the system, review pending tasks, and start autonomous execution mode. Use this skill when the user asks to create a new development task using `/sugar-task`, check the system status with `/sugar-status`, review pending tasks via `/sugar-review`, or initiate autonomous development using `/sugar-run`. It provides a comprehensive interface for interacting with the Sugar autonomous development system.

Terraform infrastructure specialist for Vertex AI ADK Agent Engine production deployments. Provisions Agent Engine runtime, Code Execution Sandbox, Memory Bank, VPC-SC, IAM, and secure multi-agent infrastructure. Triggers: "deploy adk terraform", "agent engine infrastructure", "adk production deployment", "vpc-sc agent engine"

This skill uses the stored-procedure-generator plugin to create production-ready stored procedures, functions, triggers, and custom database logic. It supports PostgreSQL, MySQL, and SQL Server. Use this skill when the user asks to "generate stored procedure", "create database function", "write a trigger", or needs help with "database logic", "optimizing database performance", or "ensuring transaction safety" in their database. The skill is activated by requests related to database stored procedures, functions, or triggers.

> Generate, modify, and style React components from natural language using the Thesys SDK. Guides schema-driven UI generation, theme customisation, tool calling integration, and deployment to Vite, Next.js, or Cloudflare Workers. Use when the user says "generate UI", "create a component", "build an interface", "Thesys", "generative UI", or asks to turn a description into a React component.

Fix PHP coding style issues using PHPCS and PHPCBF. Use this skill whenever the user mentions PHPCS, code style, coding standard, cs:fix, cs:check, PHP formatting, or asks to fix/check PHP code style. Also activate when you notice PHP files have been modified and need style compliance, or when a CI PHPCS check has failed.

Critically review and refine tests generated during a coding session. Use this skill when the user asks to review tests, clean up tests, refine tests, prune tests, improve test quality, or remove useless/low-value tests. Also use when the user says 'review my tests', 'clean up tests', or mentions test quality after a coding session.

Integrates payment processing with Stripe, PayPal, or Square including subscriptions, webhooks, and PCI compliance. Use when implementing checkout flows, recurring billing, or handling refunds and disputes.

Use when building server-rendered React with Bun, including streaming SSR, hydration, renderToString, or custom SSR without a framework.
