API Design Patterns provides conventions and best practices for designing consistent, developer-friendly REST APIs, including resource naming, HTTP status codes, pagination, filtering, error responses, versioning, and rate limiting.

Backend Patterns provides architectural patterns and best practices for building scalable server-side applications, covering REST API design, repository/service layers, database optimization, caching, and error handling. Use it when implementing Node.js, Express, or Next.js API routes.

Content Hash Cache Pattern caches expensive file processing results using SHA-256 content hashes instead of file paths, so cached results survive file moves and invalidate automatically on content changes. Use it when building file processing pipelines, CLIs with cache flags, or adding caching to pure functions.

Database Migrations covers safe, reversible schema changes across PostgreSQL, MySQL, and common ORMs like Prisma, Drizzle, Django, and golang-migrate, with zero-downtime patterns. Use it when creating or altering tables, adding indexes, backfilling data, or planning production migrations.

Deployment Patterns provides CI/CD pipeline templates, Docker containerization examples, deployment strategies (rolling, blue-green, canary), health checks, and production readiness checklists for web applications.

Django Patterns provides production-grade Django architecture patterns, including REST API design with DRF, ORM best practices, caching, signals, middleware, and project structure for scalable maintainable apps.

Docker Patterns provides Docker and Docker Compose best practices for local development, container security, networking, volume management, and multi-service orchestration. Use it when setting up development environments, designing multi-container architectures, or troubleshooting container issues.

Git Push commits and pushes vault changes to Git with smart commit messages, auto-staging files, creating meaningful commits, and syncing with remote. Use after making vault changes or at end of day.

Upgrade Obsidian Claude PKM Vault updates your vault's system files to the latest version, preserving personal content. It creates a backup, shows diffs, and applies updates file-by-file with confirmation.

Release automates creating a new grepai version: it checks CI status, categorizes merged PRs to determine a semantic version bump, updates CHANGELOG.md and documentation, credits contributors, and creates a GitHub release. Use it when you need to publish a new version.

Find Hypertable Candidates analyzes an existing PostgreSQL database to identify which tables should be converted to Timescale/TimescaleDB hypertables. Use it when auditing tables for time-series or insert-heavy workloads and evaluating hypertable candidacy before migration.

Ghost Database creates and manages PostgreSQL databases for agent workflows, with on-demand creation, instant forks for safe testing, and shareable snapshots. Use it when an agent needs persistent storage or wants to pass databases as assets between workflows.
