Output Styles Meta Skill

🚨 MANDATORY: Invoke docs-management First

STOP - Before providing ANY response about output styles:

1. INVOKE docs-management skill
2. QUERY for the user's specific topic
3. BASE all responses EXCLUSIVELY on official documentation loaded

Skipping this step results in outdated or incorrect information.

Verification Checkpoint

Before responding, verify:

• Did I invoke docs-management skill?
• Did official documentation load?
• Is my response based EXCLUSIVELY on official docs?

If ANY checkbox is unchecked, STOP and invoke docs-management first.

Quick Decision Tree

What do you want to do?

1. Understand available styles -> Query docs-management: "built-in output styles", "output style overview"
2. Use default coding assistant -> Query docs-management: "default output style", "software engineering style"
3. Learn about the codebase -> Query docs-management: "explanatory style", "educational insights"
4. Learn by doing (hands-on) -> Query docs-management: "learning style", "TODO human markers", "learn-by-doing"
5. Switch output style -> Query docs-management: "/output-style command", "switch output style"
6. Create custom style -> Query docs-management: "create custom output style", "output style frontmatter"
7. Compare to related features -> Query docs-management: "output styles vs CLAUDE.md", "output styles vs agents"
8. Where to save style files -> Query docs-management: "output style file location", "~/.claude/output-styles"

Topic Coverage

Built-in Output Styles

• Default: Standard software engineering assistant behavior
• Explanatory: Adds educational "Insights" between tasks to help understand implementation choices
• Learning: Collaborative learn-by-doing mode with TODO(human) markers for user contributions

Output Style Frontmatter

• name field (optional - defaults to filename)
• description field (optional - for UI display in /output-style menu)
• keep-coding-instructions field (optional - default false, whether to keep coding instructions in system prompt)

Style Configuration Options

• Default style configuration
• Per-session style switching
• Style persistence across sessions

/output-style Command

• List available styles
• Switch to different style
• View current style
• Style selection syntax

Custom Style Creation

• File location for custom styles
• Frontmatter structure
• Prompt crafting for custom behavior
• Testing and validation

Style Selection Criteria

• Task-based recommendations
• Verbosity preferences
• Output format needs
• Code vs explanation balance

Style Comparisons

• Output Styles vs CLAUDE.md vs --append-system-prompt (system prompt modification approaches)
• Output Styles vs Agents (main loop vs specific tasks, different configuration options)
• Output Styles vs Slash Commands (stored system prompts vs stored prompts)
• When to use each approach

Delegation Patterns

Standard Query Pattern

User asks: "What output styles are available?"

1. Invoke docs-management skill
2. Use keywords: "built-in output styles", "output style overview"
3. Load official documentation
4. Provide guidance based EXCLUSIVELY on official docs

Multi-Topic Query Pattern

User asks: "I want brief responses with less code"

1. Invoke docs-management skill with multiple queries:
   - "concise style", "brief responses"
   - "code-sparse style", "minimal code"
2. Synthesize guidance from official documentation

Troubleshooting Pattern

User reports: "My custom output style isn't working"

1. Invoke docs-management skill
2. Use keywords: "output style frontmatter", "create custom output style"
3. Check official docs for style configuration requirements
4. Guide user through proper style setup

Troubleshooting Quick Reference

Issue	Keywords for docs-management
Style not changing	"/output-style command", "switch output style"
Custom style not loading	"output style frontmatter", "style file location"
Too verbose responses	"concise style", "brief responses"
Not enough detail	"verbose style", "detailed responses"
Want formatted output	"markdown style", "formatted output"
Too much code in output	"code-sparse style", "minimal code"
Style selection guidance	"output style use cases", "style recommendations"

Repository-Specific Notes

This repository does not currently use custom output styles. Output style documentation is relevant for:

• Understanding how output styles affect response behavior
• Potential custom style creation for repository-specific workflows
• Understanding style configuration for team preferences

When working with output style topics, always use the docs-management skill to access official documentation.

Auditing Output Styles

This skill provides the validation criteria used by the output-style-auditor agent for formal audits.

Audit Resources

Resource	Location	Purpose
Audit Framework	references/audit-framework.md	Query guides and scoring criteria

Scoring Categories

Category	Points	Key Criteria
File Structure	20	Correct location, .md extension
YAML Frontmatter	30	Required fields present and valid
Content Quality	30	Clear instructions, proper structure
Compatibility	20	Works with style switching, no conflicts

Thresholds: 85+ = PASS, 70-84 = PASS WITH WARNINGS, <70 = FAIL

Related Agent

The output-style-auditor agent (Haiku model) performs formal audits using this skill:
