aiskillstore Creating Commands
Guides creation of Claude Code slash commands using documented best practices.
Quick Start
For a new command:
- Ask user for command purpose and arguments needed
- Generate using appropriate template
- Validate against checklist
For reviewing existing command:
- Read command file
- Check against anti-patterns in reference.md
- Report issues with fixes
Workflow: Create New Command
Progress:
- [ ] Gather requirements (purpose, arguments, scope)
- [ ] Choose template (basic, with-args, workflow)
- [ ] Generate command file
- [ ] Validate against checklist
Step 1: Gather Requirements
Ask user with AskUserQuestion:
- What should this command do? (purpose)
- Does it need arguments? (none, single, multiple)
- Project or personal? (scope)
Step 2: Choose Template
| Type | Template | When to Use |
|---|---|---|
| Basic | templates/basic.md | No arguments, simple prompt |
| With Args | templates/with-args.md | Single or multiple arguments |
| Workflow | templates/workflow.md | Integrates with skills/agents |
Step 3: Generate Command
Create in appropriate location:
.claude/commands/- Project commands (git-tracked)~/.claude/commands/- Personal commands (your machine only)
Step 4: Validate
Run through checklist before finishing:
Validation Checklist:
