EOF

Your markdown instructions here.
Use $1, $2 for arguments or $ARGUMENTS for all.

Bash Execution

Run bash before loading prompt with ! prefix:

---
allowed-tools: Bash(git:*), Bash(grep:*)
description: Git commit helper
---

Current status: !`git status`
Staged changes: !`git diff --staged`
Recent commits: !`git log --oneline -5`

Based on these changes, suggest a commit message.

Rules:

  • Must declare allowed-tools: Bash(...) in frontmatter
  • Use backticks: !command
  • Output is included in Claude's context

File References

Include files with @ prefix:

Review against @.claude/STYLE_GUIDE.md

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

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

Arguments

---
argument-hint: "[pr-number] [priority]"
---

Review PR #$1 with priority: $2

# Or use all arguments:
Fix issue #$ARGUMENTS

Usage:

/review-pr 456 high
# $1 = "456", $2 = "high"

Namespacing

Organize with subdirectories:

.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

| Aspect | Slash Commands | 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

Example: Complete Git Commit Command

---
description: Generate semantic commit message
allowed-tools: Bash(git:*), Read
argument-hint: "[type]"
---

# Semantic Commit Generator

Staged files: !`git diff --name-only --cached`

Diff preview:
!`git diff --cached | head -100`

Generate a conventional commit message.
Type: $1 (feat/fix/docs/style/refactor/perf/test/chore)

Format: `<type>(<scope>): <subject>`

Usage: /commit feat

How to use it

Copy the folder

Take parcadei/slash-commands from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
