• Use backticks: !`command`
• Output is included in Claude's context

File References

Review against @.claude/STYLE_GUIDE.md

Compare:
- @src/old.js
- @src/new.js

Refactor files matching @src/**/*.util.ts

# $1 = "456", $2 = "high"

Namespacing

.claude/commands/
├── frontend/
│   └── component.md    → /component (project:frontend)
└── backend/
    └── endpoint.md     → /endpoint (project:backend)

MCP Slash Commands

MCP servers expose prompts as commands:

/mcp__github__list_prs
/mcp__github__pr_review 456
/mcp__jira__create_issue "Bug" high

Slash Commands vs Skills

Invocation	Explicit: /command	Auto-discovered
Files	Single .md file	Directory with SKILL.md
Use Case	Quick prompts	Complex workflows

Use slash commands for: Frequently typed prompts, simple templates Use skills for: Complex workflows, multiple files, auto-discovery
