Bun runtime patterns including native APIs, SQLite, testing, HTTP server, WebSocket, file handling, and shell operations. Use when working with Bun runtime, bun:sqlite, Bun.serve, bun:test, or when Bun, --bun flag, SQLite, or Bun-specific patterns mentioned.

Diagnose book marketing copy problems and generate platform-optimized blurbs, descriptions, taglines, and query pitches. Use when marketing copy feels weak, when descriptions aren't converting, or when starting marketing from scratch.

Targeted query capabilities for machine-readable codebase documentation with cross-reference tracking, call graph analysis, and workflow automation. Enables fast lookups of classes, functions, dependencies, and function relationships without parsing source code.

Configure Claude Code sandbox network isolation with trusted domains, custom access policies, and environment variables

Create and manage Dexie/IndexedDB repositories with type-safe interfaces, converters, and standardized CRUD operations. Use when (1) adding entity storage, (2) implementing save/load/delete operations, (3) designing database schema and indexes, (4) converting between database (Db*) and domain types, (5) handling database errors or migrations, (6) using existing repositories (SettingsRepository, WorkoutsRepository, TemplatesRepository, CustomExercisesRepository, BenchmarksRepository, ActiveWorkoutRepository). Triggers include "database", "repository", "save data", "fetch from database", "delete from storage", "database schema", "database table", "indexes", "migration", "persist", "convert workout", "converter", "buildPartialUpdate", "mock repository", "database error", "bulk operations", "import/export", or specific repository names.

AI-driven deployment management using Dokploy MCP server for projects, applications, and databases

Horizontal scaling patterns for multi-tenant databases. Covers shard key selection, consistent hashing, and shard management.

Decentralized database protocol with zero-knowledge proofs and permanent storage on Arweave

Expert Celery distributed task queue engineer specializing in async task processing, workflow orchestration, broker configuration (Redis/RabbitMQ), Celery Beat scheduling, and production monitoring. Deep expertise in task patterns (chains, groups, chords), retries, rate limiting, Flower monitoring, and security best practices. Use when designing distributed task systems, implementing background job processing, building workflow orchestration, or optimizing task queue performance.

Database specialist covering PostgreSQL, MongoDB, Redis, and advanced data patterns for modern applications

Run the case feedback script to submit feedback for the current conversation. Only use when invoked by case-feedback-agent.

Iteratively refine frontend designs until they achieve a 10/10 rating. Use when asked to "refine this design", "polish this UI", "get this to 10/10", or improve visual design quality. Covers UI iteration, design feedback loops, and screenshot-based review workflows.

This skill should be used as a mandatory final sanity check before git commit, PR creation, or declaring work done. Triggers on "commit", "push", "PR", "pull request", "done", "finished", "complete", "ship", "deploy", "ready to merge". Catches security vulnerabilities, logic errors, and business rule bugs that slip through despite passing tests.
