Reviews documentation for completeness, accuracy, and consistency with the project's DX_GUIDE.md standards. Validates documentation structure, checks for broken links, ensures examples are up-to-date, and verifies technical accuracy. Use when creating or updating documentation, reviewing doc-heavy PRs, or ensuring doc quality.

Scans for project documentation files (AGENTS.md, CLAUDE.md, GEMINI.md, COPILOT.md, CURSOR.md, WARP.md, and 15+ other formats) and synthesizes guidance. Auto-activates when user asks to review, understand, or explore a codebase, when starting work in a new project, when asking about conventions or agents, or when documentation context would help. Can consolidate multiple platform docs into unified AGENTS.md.

Token-efficient documentation search using Serena Document Index. 90%+ token savings vs reading full files. Use BEFORE reading README.md or docs/ files. Triggers on architecture questions, pattern lookups, and project-specific documentation needs.

Create Technical Specifications (SPEC) - Layer 10 artifact using YAML format for implementation-ready specifications

A SKILL.md file that defines a Claude Code skill with metadata, instructions, and examples

Maintains the CLAUDE.md navigation hierarchy and optional README.md architecture docs across a repository. This skill is self-contained and performs all documentation work directly.

Create System Requirements (SYS) - Layer 6 artifact defining functional requirements and quality attributes

Create Task Breakdown (TASKS) - Layer 11 artifact decomposing SPEC into AI-structured TODO tasks

Update development blog with implementation milestones, learnings, and progress. Use after completing major milestones or phases.

Updates documentation after code changes to keep docs in sync with code reality. Use AFTER implementation is complete. Covers feature docs, workflow docs, and index files.

Validate markdown files for formatting, links, and style compliance using markdownlint. Use before committing documentation changes.

DocETL is a system for creating LLM-powered data processing pipelines. This skill helps you build end-to-end pipelines: from data preparation to execution and optimization.

SOTA Docker/Compose architecture, implementation, refactor, and security hardening. Use when working on containerization tasks such as creating or rewriting Dockerfiles, docker-compose files, buildx/bake configs, .dockerignore, and CI pipelines for build/test/scan/publish; auditing existing container setups for security, correctness, size/perf, and best practices (least privilege, non-root, minimal images, pinned base images, BuildKit secrets, healthchecks); debugging Docker build/run issues; or designing dev vs prod compose workflows across services (DB/cache/queues) with correct networking, volumes, secrets, and resource limits.

Docker containerization patterns for Node.js applications. Use when containerizing backend services.

Dockerizes backend projects with auto-detection, latest base images via web search, Dockerfile generation, and Makefile with port override support.

Apply when containerizing applications: writing Dockerfiles, docker-compose configurations, and multi-stage builds.

Create optimized Dockerfiles with multi-stage builds, security hardening, layer caching, and health checks. Includes docker-compose patterns for development and production environments.

This skill provides guidance for efficiently building, testing, and working with

Docker build and test workflow with mandatory pre-push validation checklist to prevent CI/CD failures

Docker integration with CI/CD pipelines for automated builds, testing, and deployments

Execute all package installations and code execution inside Docker containers. This keeps the host machine clean and ensures consistent environments across projects.

ICJC Docker 서비스 관리 및 Make 명령어. Use when: (1) docker, make, 컨테이너, 서비스, 재시작, 로그 관련 요청, (2) 백엔드/프론트엔드/에이전트 재시작, (3) 빌드, 컨테이너 접속, 로그 확인, 서비스 상태 확인 필요시.

Use when configuring networks and service communication in Docker Compose including bridge networks, overlay networks, service discovery, and inter-service communication.

Operations for local container stacks defined in docker-compose.yaml or docker-compose/ directory. Handles AI/ML services (Ollama, ComfyUI), standalone databases, and local observability stacks. Use for 'docker compose' commands, checking container logs, or restarting specific local services. For cluster Grafana/Prometheus (via kubectl or cluster/manifests/), use kubernetes-operations instead.

Container orchestration with Docker Compose for multi-container applications, networking, volumes, and production deployment

Converts Docker Compose configurations to NixOS modules using the dendritic pattern with Arion. Creates modules with system users, sops secrets, Arion docker-compose config, and Tailscale integration. Use when converting docker-compose.yaml files to NixOS modules or creating new Arion-based services.

Multi-service orchestration with Docker Compose, focusing on network isolation, environment-specific profiles, and service discovery. Triggers: docker-compose, container-networking, docker-profiles, service-discovery, yaml-config.
