Databases

This skill should be used when the user asks to "use the oracle" or "ask the oracle" for deep research, analysis, or architectural questions. The oracle excels at multi-source research combining codebase exploration and web searches, then synthesizing findings into actionable answers. Use for complex questions requiring investigation across multiple sources, architectural analysis, refactoring plans, debugging mysteries, and code reviews.

Astro + React islands with TanStack (Query, Form, Table) and Tailwind CSS. Use for frontend UI development, components, data fetching, forms, and styling.

Configure KPI number displays in drizzle-cube dashboards for showing single metric values with formatting. Use when displaying KPIs, single numbers, metrics, totals, or key performance indicators.

Test and validate ClickHouse Cloud connection using clickhouse-connect for gapless-crypto-clickhouse. Use when validating connectivity, troubleshooting connection issues, or verifying environment configuration. Includes version check and query validation.

Reviews code for best practices, security vulnerabilities, and adherence to the project's style guide. It provides actionable feedback and refactoring suggestions.

Query database structure and business rules. Auto-documents new findings.

Use when receiving code review feedback (especially if unclear or technically questionable), when completing tasks or major features requiring review before proceeding, or before making any completion/success claims. Covers three practices - receiving feedback with technical rigor over performative agreement, requesting reviews via code-reviewer subagent, and verification gates requiring evidence before any status claims. Essential for subagent-driven development, pull requests, and preventing false completion claims.

Implement real-time streaming UI patterns for AI chat applications. Use when adding responselifecycle handlers, progress indicators, client effects, or thread state synchronization.Covers onResponseStart/End, onEffect, ProgressUpdateEvent, and client tools.NOT when building basic chat without real-time feedback.

Code review workflow and best practices.Use when: reviewing PRs, receiving feedback, or preparing code for review.Triggers: "code review", "review", "pr review", "pull request","feedback", "review changes".

Handling authentication and authorization in StickerNest. Use when the user asks about login, signup, auth, session, protected routes, user context, JWT, tokens, logout, or permission checks. Covers Supabase Auth, AuthContext, protected routes, and widget auth.

Datadog CLI for searching logs, querying metrics, tracing requests, and managing dashboards. Use this when debugging production issues or working with Datadog observability.

Use when developing BigQuery Dataform transformations, SQLX files, source declarations, or troubleshooting pipelines - enforces TDD workflow (tests first), ALWAYS use ${ref()} never hardcoded table paths, comprehensive columns:{} documentation, safety practices (--schema-suffix dev, --dry-run), proper ref() syntax, .sqlx for new declarations, no schema config in operations/tests, and architecture patterns that prevent technical debt under time pressure

Expert guidance for writing clean, simple, and effective unit, integration, component, microservice, and API tests. Use this skill when reviewing existing tests for violations, writing new tests, or refactoring tests. NOT for end-to-end tests that span multiple processes - use testing-e2e skill instead. Covers AAA pattern, data factories, mocking strategies, DOM testing, database testing, and assertion best practices.

Detects various injection vulnerabilities including SQL injection, LDAP injection, XPath injection, and code injection. Use when analyzing database queries, dynamic code generation, or investigating injection attacks.

Scaffolds a new Python tool utility in 'src/tools/' for agents to call. Tools are utility functions (web scraping, PDF parsing, database queries) that agents use. Use when creating utilities that agents depend on.

Google Cloud Platform infrastructure patterns and best practices. Use when designing or implementing GCP solutions including Compute Engine, Cloud Functions, Cloud Storage, and BigQuery.
