What Are Claude Code Skills?

Skills are markdown-based prompt modules that extend Claude Code's capabilities. Drop a skill folder into ~/.claude/skills/ and Claude gains specialized knowledge — from automating Slack workflows to running Semgrep scans to generating podcast audio.

Each skill directory contains:

File	Purpose
SKILL.md	Core instructions, workflows, and trigger conditions
CLAUDE.md	Optional project-level overrides for Claude Code
references/	Supporting docs, examples, API schemas
scripts/	Executable helpers (Python, Node, shell)

How Skills Work

User: "Send a message to #general in Slack saying deployment is done"

Claude Code:
  1. Matches intent → loads slack-automation skill
  2. Skill provides: API surface, auth flow, tool schemas
  3. Claude executes: RUBE_SEARCH_TOOLS → find send_message → call it
  4. Result: Message sent to #general ✓

Skills trigger automatically based on context, or can be invoked explicitly via /skill-name in Claude Code.
