Purpose

To create new CLI skills following Anthropic’s official best practices with zero manual configuration. This skill automates brainstorming, template application, validation, and installation processes while maintaining progressive disclosure patterns and writing style standards.

When to Use This Skill

This skill should be used when:

  • User wants to extend CLI functionality with custom capabilities
  • User needs to create a skill following official standards
  • User wants to automate repetitive CLI tasks with a reusable skill
  • User needs to package domain knowledge into a skill format
  • User wants both local and global skill installation options

Core Capabilities

  1. Interactive Brainstorming – Collaborative session to define skill purpose and scope
  2. Prompt Enhancement – Optional integration with prompt-engineer skill for refinement
  3. Template Application – Automatic file generation from standardized templates
  4. Validation – YAML, content, and style checks against Anthropic standards
  5. Installation – Local repository or global installation with symlinks
  6. Progress Tracking – Visual gauge showing completion status at each step

Step 0: Discovery

Before starting skill creation, gather runtime information:

# Detect available platforms
COPILOT_INSTALLED=false
CLAUDE_INSTALLED=false
CODEX_INSTALLED=false

if command -v gh &>/dev/null && gh copilot --version &>/dev/null 2>&1; then
    COPILOT_INSTALLED=true
fi

if [[ -d "$HOME/.claude" ]]; then
    CLAUDE_INSTALLED=true
fi

if [[ -d "$HOME/.codex" ]]; then
    CODEX_INSTALLED=true
fi

# Determine working directory
REPO_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || pwd)
SKILLS_REPO="$REPO_ROOT"

# Check if in cli-ai-skills repository
if [[ ! -d "$SKILLS_REPO/.github/skills" ]]; then
    echo "⚠️  Not in cli-ai-skills repository. Creating standalone skill."
    STANDALONE=true
fi

# Get user info from git config
AUTHOR=$(git config user.name || echo "Unknown")
EMAIL=$(git config user.email || echo "")

Key Information Needed:

  • Which platforms to target (Copilot, Claude, Codex, or all three)
  • Installation preference (local, global, or both)
  • Skill name and purpose
  • Skill type (general, code, documentation, analysis)

Main Workflow

Progress Tracking Guidelines

Throughout the workflow, display a visual progress bar before starting each phase to keep the user informed. The progress bar format is:

[████████████░░░░░░] 60% - Step 3/5: Creating SKILL.md

Format specifications:

  • 20 characters wide (use █ for filled, ░ for empty)
  • Percentage based on current step (Step 1=20%, Step 2=40%, Step 3=60%, Step 4=80%, Step 5=100%)
  • Step counter showing current/total (e.g., “Step 3/5”)
  • Brief description of current phase

Display the progress bar using:

echo "[████░░░░░░░░░░░░░░] 20% - Step 1/5: Brainstorming & Planning"

Phase 1: Brainstorming & Planning

Progress: Display before starting this phase:

echo "[████░░░░░░░░░░░░░░] 20% - Step 1/5: Brainstorming & Planning"

Ask the user:

  1. What should this skill do? (Free-form description)

    • Example: “Help users debug Python code by analyzing stack traces”

  2. When should it trigger? (Provide 3-5 trigger phrases)

    • Example: “debug Python error”, “analyze stack trace”, “fix Python exception”

  3. What type of skill is this?

    • General purpose (default template)
    • Code generation/modification
    • Documentation creation/maintenance
    • Analysis/investigation

  4. Which platforms should support this skill?

    • GitHub Copilot CLI
    • Claude Code
    • Codex
    • All three (recommended)

  5. Provide a one-sentence description (will appear in metadata)

    • Example: “Analyzes Python stack traces and suggests fixes”

Capture responses and prepare for next phase.

Generate skill structure:

# Convert skill name to kebab-case
SKILL_NAME=$(echo "$USER_INPUT" | tr '[:upper:]' '[:lower:]' | tr ' ' '-')

# Create directories
if [[ "$PLATFORM" =~ "copilot" ]]; then
    mkdir -p ".github/skills/$SKILL_NAME"/{references,examples,scripts}
fi

if [[ "$PLATFORM" =~ "claude" ]]; then
    mkdir -p ".claude/skills/$SKILL_NAME"/{references,examples,scripts}
fi

if [[ "$PLATFORM" =~ "codex" ]]; then
    mkdir -p ".codex/skills/$SKILL_NAME"/{references,examples,scripts}
fi

Apply templates:

  1. SKILL.md – Use appropriate template:

    • skill-template-copilot.md, skill-template-claude.md, or skill-template-codex.md
    • Substitute placeholders:
      • {{SKILL_NAME}} → kebab-case name
      • {{DESCRIPTION}} → one-line description
      • {{TRIGGERS}} → comma-separated trigger phrases
      • {{PURPOSE}} → detailed purpose from brainstorming
      • {{AUTHOR}} → from git config
      • {{DATE}} → current date (YYYY-MM-DD)
      • {{VERSION}} → “1.0.0”

  2. README.md – Use readme-template.md:

    • User-facing documentation (300-500 words)
    • Include installation instructions
    • Add usage examples

  3. References/ (optional but recommended):

    • Create detailed-guide.md for extended documentation (2k-5k words)
    • Move lengthy content here to keep SKILL.md under 2k words

File creation commands:

# Apply template with substitution
sed "s/{{SKILL_NAME}}/$SKILL_NAME/g; \
     s/{{DESCRIPTION}}/$DESCRIPTION/g; \
     s/{{AUTHOR}}/$AUTHOR/g; \
     s/{{DATE}}/$(date +%Y-%m-%d)/g" \

  • Repository only – Files created in .github/skills/ (works when in repo)
  • Global installation – Create symlinks in ~/.copilot/skills/ (works everywhere)
  • Both – Repository + global symlinks (recommended, auto-updates with git pull)
  • Skip installation – Just create files

If global installation selected:

# Detect which platforms to install for

Error Handling

Platform Detection Issues

If platforms cannot be detected:

⚠️  Unable to detect GitHub Copilot CLI or Claude Code
    
Would you like to:
1. Install for repository only (works when in repo)
2. Specify platform manually
3. Skip installation

Template Not Found

If templates are missing:

❌ Error: Template not found at resources/templates/

This skill requires the cli-ai-skills repository structure.

Options:
1. Clone cli-ai-skills: git clone <repo-url>
2. Create minimal skill structure manually
3. Exit and set up templates first

Validation Failures

If content doesn’t meet standards:

⚠️  Validation Issues Found:

1. YAML: Description not in third-person format
   Expected: "This skill should be used when..."
   Found: "Use this skill when..."
   
2. Content: Word count too high (5,342 words, max 5,000)
   Suggestion: Move detailed sections to references/

Fix automatically? [Y/n]

Installation Conflicts

If symlink already exists:

⚠️  Skill already installed at ~/.copilot/skills/your-skill-name

Options:
1. Overwrite existing installation
2. Rename new skill
3. Skip installation
4. Install to different location
