Agent skill
slashcommandcreator
Autonomous meta-skill for creating high-quality custom slash commands using 5-phase workflow with multi-agent validation and quality gates. Use when user requests new slash command, reusable prompt automation, or wants to convert repetitive workflows into documented commands.

SlashCommandCreator Skill
Purpose
Create production-ready custom slash commands following ai-agents quality standards.
Triggers
create slash command for [purpose]SlashCommandCreator: [description]design slash command that [does something]
When to Use
- User requests "create slash command for [purpose]"
- Repetitive prompts identified in workflow
- Converting manual workflows to automation
- Need reusable, documented command patterns
5-Phase Workflow
Phase 1: Discovery & Analysis
Agent Mode: Analyst
Tasks:
- Clarify user intent: What prompt is being repeated?
- Search existing commands:
ls .claude/commands/**/*.md - Decision: Slash command vs skill (see decision matrix in CLAUDE.md)
- Apply 11 thinking models from skillcreator framework
- Document findings in
.agents/analysis/slashcommand-[name]-analysis.md
Deliverable: Analysis document with recommendation
Phase 2: Design
Agent Mode: Architect
Tasks:
- Command naming (namespace conventions)
- Argument design:
- Simple commands: use
$ARGUMENTS - Complex commands: use
$1,$2,$3(positional)
- Simple commands: use
- Frontmatter schema:
description(trigger-based per creator-001)argument-hint(if using arguments)allowed-tools(if using bash commands with!or file references with@)model(opus for complex reasoning)disable-model-invocation(if pure prompt template)
- Dynamic context evaluation:
- Bash execution (
!git log --oneline -5) - File references (
@.agents/HANDOFF.md)
- Bash execution (
- Extended thinking evaluation:
- Add
ultrathinkkeyword for complex reasoning (>5 steps) - Token budget consideration (<31,999 tokens)
- Add
Deliverable: Design specification with frontmatter + prompt
Phase 3: Multi-Agent Validation
Agent Mode: Orchestrator (coordinates 4 agents)
Agents:
-
Security:
- Review
allowed-toolsconstraints - Flag overly permissive wildcards
- Verify bash commands are safe
- Review
-
Architect:
- Check for duplication (similar existing commands)
- Verify appropriate scope (not too broad/narrow)
- Validate namespace conventions
-
Independent-Thinker:
- Challenge necessity: Is this really needed?
- Propose alternatives
- Question assumptions
-
Critic:
- Frontmatter completeness check
- Trigger-based description validation
- Argument-hint clarity
Unanimous Approval Required: All 4 agents must approve.
Invocation Pattern:
# Security review
Task(subagent_type="security", prompt="Review allowed-tools for command: [spec]")
# Architecture review
Task(subagent_type="architect", prompt="Check for duplication: [spec]")
# Challenge necessity
Task(subagent_type="independent-thinker", prompt="Is this command truly needed? [spec]")
# Frontmatter completeness
Task(subagent_type="critic", prompt="Validate frontmatter completeness: [spec]")
Deliverable: Validation report with approvals or revision requests
Phase 4: Implementation
Agent Mode: Implementer
Tasks:
- Run
python3 .claude/skills/slashcommandcreator/scripts/new_slash_command.py - Create
.claude/commands/[namespace]/[command].md - Write frontmatter + prompt body
- Test invocation with sample arguments
- Update command catalog (if exists)
Deliverable: Working slash command file
Phase 5: Quality Gates (Automatic)
Agent Mode: Implementer (automatic validation)
Tasks:
- Run
python3 .claude/skills/slashcommandcreator/scripts/validate_slash_command.py --path [file] - Fix violations if any
- Re-run validation until exit code 0
- Commit with conventional commit message
Deliverable: Validated slash command ready for use
Invocation Examples
SlashCommandCreator: create command for exporting Forgetful memories to JSON
SlashCommandCreator: design slash command for running security audit
create slash command that summarizes recent PR comments
Decision Matrix: Slash Command vs Skill
Use Slash Command When:
- Prompt is <200 lines
- No multi-step conditional logic
- Simple argument substitution
- No external script orchestration
Use Skill When:
- Prompt is >200 lines
- Multi-agent coordination required
- Complex scripting logic
- Requires dedicated tests
Verification/Success Criteria
Before marking complete:
- Frontmatter has
description(trigger-based) - Frontmatter has
argument-hint(if uses arguments) - Frontmatter has
allowed-tools(if uses bash/file refs) - No overly permissive wildcards in
allowed-tools - Description follows trigger-based pattern (creator-001)
- File is <200 lines (or converted to skill)
- Passes
markdownlint-cli2validation - Passes
validate_slash_command.pyvalidation - Tested with sample arguments
- Committed with conventional commit message
Success Criteria:
| Metric | Target |
|---|---|
| Validation | Exit code 0 from validate_slash_command.py |
| Testing | Command runs without errors with sample arguments |
| Documentation | Description clearly explains when to use command |
| Security | All bash/file refs have explicit allowed-tools entries |
Anti-Patterns
| Avoid | Why | Instead |
|---|---|---|
| Creating commands > 200 lines | Too complex for slash command format | Convert to a skill instead |
Overly permissive allowed-tools wildcards |
Security risk | List specific tools needed |
| Skipping multi-agent validation | Miss security, scope, or necessity issues | Run all 4 validation agents |
| Duplicate commands for similar purposes | Confusing discoverability | Check existing commands first |
| Generic description without trigger keywords | Model cannot find the command | Include specific "Use when" phrases |
Quality Gates Checklist
All checks from Verification section plus:
- Multi-agent approval (security, architect, independent-thinker, critic)
- No duplication with existing commands
- Appropriate scope (not too broad/narrow)
- Frontmatter completeness validated
