Customization

Before executing, check for user customizations at: ~/.claude/skills/CORE/USER/SKILLCUSTOMIZATIONS/CreateSkill/

If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.

CreateSkill

MANDATORY skill creation framework for ALL skill creation requests.

Authoritative Source

Before creating ANY skill, READ: ~/.claude/skills/CORE/SkillSystem.md

Canonical example to follow: ~/.claude/skills/_BLOGGING/SKILL.md

TitleCase Naming Convention

All naming must use TitleCase (PascalCase).

ComponentFormatExample
Skill directoryTitleCaseBlogging, Daemon, CreateSkill
Workflow filesTitleCase.mdCreate.md, UpdateDaemonInfo.md
Reference docsTitleCase.mdProsodyGuide.md, ApiReference.md
Tool filesTitleCase.tsManageServer.ts
Help filesTitleCase.help.mdManageServer.help.md

Wrong (NEVER use):

  • createskill, create-skill, CREATE_SKILL
  • create.md, update-info.md, SYNC_REPO.md

Flat Folder Structure (MANDATORY)

CRITICAL: Keep folder structure FLAT - maximum 2 levels deep.

The Rule

Maximum depth: skills/SkillName/Category/

ALLOWED (2 levels max)

skills/SkillName/SKILL.md                    # Skill root
skills/SkillName/Workflows/Create.md         # Workflow - one level deep - GOOD
skills/SkillName/Tools/Manage.ts             # Tool - one level deep - GOOD
skills/SkillName/QuickStartGuide.md          # Context file - in root - GOOD
skills/SkillName/Examples.md                 # Context file - in root - GOOD

FORBIDDEN (Too deep OR wrong location)

skills/SkillName/Resources/Guide.md              # Context files go in root, NOT Resources/
skills/SkillName/Docs/Examples.md                # Context files go in root, NOT Docs/
skills/SkillName/Workflows/Category/File.md      # THREE levels - NO
skills/SkillName/Templates/Primitives/File.md    # THREE levels - NO
skills/SkillName/Tools/Utils/Helper.ts           # THREE levels - NO

Allowed Subdirectories

ONLY these subdirectories are allowed:

  • Workflows/ - Execution workflows ONLY
  • Tools/ - Executable scripts/tools ONLY

Context files (documentation, guides, references) go in the skill ROOT, NOT in subdirectories.

Why

  1. Discoverability - Easy to find files
  2. Simplicity - Less navigation overhead
  3. Speed - Faster file operations
  4. Consistency - Every skill follows same pattern

If you need to organize many workflows, use clear filenames instead of subdirectories:

  • Good: Workflows/CompanyDueDiligence.md
  • Bad: Workflows/Company/DueDiligence.md

See: ~/.claude/skills/CORE/SkillSystem.md (Flat Folder Structure section)


Dynamic Loading Pattern (Large Skills)

For skills with SKILL.md > 100 lines: Use dynamic loading to reduce context on skill invocation.

How Loading Works

Session startup: Only frontmatter loads for routing Skill invocation: Full SKILL.md loads Context files: Load only when workflows reference them

The Pattern

SKILL.md = Minimal (30-50 lines) - loads on skill invocation

  • YAML frontmatter with triggers
  • Brief description
  • Workflow routing table
  • Quick reference
  • Pointers to context files

Additional .md files = Context files - SOPs for specific aspects (loaded on-demand)

  • These are Standard Operating Procedures, not just documentation
  • They provide specific handling instructions
  • Can reference Workflows/, Tools/, etc.

CRITICAL: NO Context/ Subdirectory

NEVER create Context/ or Docs/ subdirectories.

Additional .md files ARE the context files. They live directly in skill root.

WRONG:

skills/Art/
  SKILL.md
  Context/              # NEVER CREATE THIS
    Aesthetic.md

CORRECT:

skills/Art/
  SKILL.md
  Aesthetic.md          # Context file in skill root
  Examples.md           # Context file in skill root
  Tools.md              # Context file in skill root

The skill directory IS the context.

Example Structure

skills/Art/
  SKILL.md              # 40 lines - minimal routing
  Aesthetic.md          # Context file - SOP for aesthetic
  Examples.md           # Context file - SOP for examples
  Tools.md              # Context file - SOP for tools
  Workflows/            # Workflows
    Essay.md
  Tools/                # CLI tools
    Generate.ts

## Workflow Routing

| Trigger | Workflow |
|---------|----------|
| "trigger" | `Workflows/WorkflowName.md` |

## Quick Reference

**Key points** (3-5 bullet points)

**Full Documentation:**
- Detail 1: `SkillSearch('skillname detail1')` -> loads Detail1.md
- Detail 2: `SkillSearch('skillname detail2')` -> loads Detail2.md

When To Use

Use dynamic loading for:

  • SKILL.md > 100 lines
  • Multiple documentation sections
  • Extensive API reference
  • Detailed examples

Don't use for:

  • Simple skills (< 50 lines)
  • Pure utility wrappers (use CORE/Tools.md instead)

Benefits

  • Token Savings: 70%+ reduction on skill invocation (when full docs not needed)
  • Organization: SKILL.md = routing, context files = SOPs for specific aspects
  • Efficiency: Workflows load only what they actually need
  • Maintainability: Easier to update individual sections

See: ~/.claude/skills/CORE/SkillSystem.md (Dynamic Loading Pattern section)


Voice Notification

When executing a workflow, do BOTH:

  1. Send voice notification:

    curl -s -X POST http://localhost:8888/notify \
      -H "Content-Type: application/json" \
      -d '{"message": "Running the WORKFLOWNAME workflow from the CreateSkill skill"}' \
      > /dev/null 2>&1 &
    
  2. Output text notification:

    Running the **WorkflowName** workflow from the **CreateSkill** skill...

Workflow Routing

WorkflowTriggerFile
CreateSkill"create a new skill"Workflows/CreateSkill.md
ValidateSkill"validate skill", "check skill"Workflows/ValidateSkill.md
UpdateSkill"update skill", "add workflow"Workflows/UpdateSkill.md
CanonicalizeSkill"canonicalize", "fix skill structure"Workflows/CanonicalizeSkill.md

Examples

Example 1: Create a new skill from scratch

User: "Create a skill for managing my recipes"
-> Invokes CreateSkill workflow
-> Reads SkillSystem.md for structure requirements
-> Creates skill directory with TitleCase naming
-> Creates SKILL.md, Workflows/, tools/
-> Generates USE WHEN triggers based on intent

Example 2: Fix an existing skill that's not routing properly

User: "The research skill isn't triggering - validate it"
-> Invokes ValidateSkill workflow
-> Checks SKILL.md against canonical format
-> Verifies TitleCase naming throughout
-> Verifies USE WHEN triggers are intent-based
-> Reports compliance issues with fixes

Example 3: Canonicalize a skill with old naming

User: "Canonicalize the daemon skill"
-> Invokes CanonicalizeSkill workflow
-> Renames workflow files to TitleCase
-> Updates routing table to match
-> Ensures Examples section exists
-> Verifies all checklist items
