Claude Code in Production Development: Skills, Hooks, MCP

How I use Claude Code as my primary tool. Custom skills, linting hooks, MCP servers for context.

Context

Claude Code isn't just a chat with AI. It's a full IDE integration with file system, git, and terminal access. But out of the box, it's generic. The real power is in customization.

Skills — Reusable Workflows

A skill is a prompt + instructions invoked via /skill-name. Examples from my workflow:

  • /simplify — reviews changed code for reuse, quality, efficiency. Finds duplication and DRY violations.
  • /init — generates CLAUDE.md for a new project by analyzing structure, stack, conventions.

Hooks — Automatic Actions

Hooks fire on events (before/after tool calls):

  • Pre-commit — runs RuboCop on changed files
  • Post-edit — checks ERB files for hardcoded Russian text (i18n enforcement)
  • File-save — auto-formats YAML

MCP Servers — Extended Context

Model Context Protocol connects external data sources. My MCPs include PostgreSQL (direct schema access), Blender (3D generation experiments), After Effects (video automation).

CLAUDE.md — The Project Brain

Each project has a CLAUDE.md with stack conventions, architectural decisions, prohibitions, and key file references. Claude Code reads it on every launch.
