Skill Management CLI

Meta-skill for managing oh-my-claudecode skills via CLI-like commands.

Subcommands

/skill list

Show all available skills organized by scope.

Behavior:

1. Scan bundled built-in skills in the plugin skills/ directory (read-only)
2. Scan user skills at ${CLAUDE_CONFIG_DIR:-~/.claude}/skills/omc-learned/
3. Scan project skills at .omc/skills/
4. Parse YAML frontmatter for metadata
5. Display in organized table format:

BUILT-IN SKILLS (bundled with oh-my-claudecode):
| Name              | Description                    | Scope    |
|-------------------|--------------------------------|----------|
| visual-verdict    | Structured visual QA verdicts  | built-in |
| ralph             | Persistence loop               | built-in |

USER SKILLS (~/.claude/skills/omc-learned/):
| Name              | Triggers           | Quality | Usage | Scope |
|-------------------|--------------------|---------|-------|-------|
| error-handler     | fix, error         | 95%     | 42    | user  |
| api-builder       | api, endpoint      | 88%     | 23    | user  |

PROJECT SKILLS (.omc/skills/):
| Name              | Triggers           | Quality | Usage | Scope   |
|-------------------|--------------------|---------|-------|---------|
| test-runner       | test, run          | 92%     | 15    | project |

Fallback: If quality/usage stats not available, show "N/A"

Built-in skill note: Built-in skills are bundled with oh-my-claudecode and are discoverable/readable, but not removed or edited through /skill remove or /skill edit.

/skill add [name]

Interactive wizard for creating a new skill.

Behavior:

1. Ask for skill name (if not provided in command)
   • Validate: lowercase, hyphens only, no spaces
2. Ask for description
   • Clear, concise one-liner
3. Ask for triggers (comma-separated keywords)
   • Example: "error, fix, debug"
4. Ask for argument hint (optional)
   • Example: " [options]"
5. Ask for scope:
   • user → ${CLAUDE_CONFIG_DIR:-~/.claude}/skills/omc-learned/<name>/SKILL.md
   • project → .omc/skills/<name>/SKILL.md
6. Create skill file with template:

---
name: <name>
description: <description>
triggers:
  - <trigger1>
  - <trigger2>
argument-hint: "<args>"
---

# <Name> Skill

## Purpose

[Describe what this skill does]

## When to Activate

[Describe triggers and conditions]

## Workflow

1. [Step 1]
2. [Step 2]
3. [Step 3]

## Examples

/oh-my-claudecode: example-arg

## Notes

[Additional context, edge cases, gotchas]

7. Report success with file path
8. Suggest: "Edit /skill edit <name> to customize content"

...

/skill setup

Interactive wizard for setting up and managing local skills (formerly local-skills-setup).

Behavior:

Step 1: Directory Check and Setup

First, check if skill directories exist and create them if needed:

# Check and create user-level skills directory
USER_SKILLS_DIR="${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/omc-learned"
if [ -d "$USER_SKILLS_DIR" ]; then
  echo "User skills directory exists: $USER_SKILLS_DIR"
else
  mkdir -p "$USER_SKILLS_DIR"
  echo "Created user skills directory: $USER_SKILLS_DIR"
fi

# Check and create project-level skills directory
PROJECT_SKILLS_DIR=".omc/skills"
if [ -d "$PROJECT_SKILLS_DIR" ]; then
  echo "Project skills directory exists: $PROJECT_SKILLS_DIR"
else
  mkdir -p "$PROJECT_SKILLS_DIR"
  echo "Created project skills directory: $PROJECT_SKILLS_DIR"
fi

Step 2: Skill Scan and Inventory

Scan both directories and show a comprehensive inventory:

# Scan user-level skills
echo "=== USER-LEVEL SKILLS (~/.claude/skills/omc-learned/) ==="
if [ -d "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/omc-learned" ]; then
  USER_COUNT=$(find "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/omc-learned" -name "*.md" 2>/dev/null | wc -l)
  echo "Total skills: $USER_COUNT"

  if [ $USER_COUNT -gt 0 ]; then
    echo ""
    echo "Skills found:"
    find "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/omc-learned" -name "*.md" -type f -exec sh -c '
      FILE="$1"
      NAME=$(grep -m1 "^name:" "$FILE" 2>/dev/null | sed "s/name: //")
      DESC=$(grep -m1 "^description:" "$FILE" 2>/dev/null | sed "s/description: //")
      MODIFIED=$(stat -c "%y" "$FILE" 2>/dev/null || stat -f "%Sm" "$FILE" 2>/dev/null)
      echo "  - $NAME"
      [ -n "$DESC" ] && echo "    Description: $DESC"
      echo "    Modified: $MODIFIED"
      echo ""
    ' sh {} \;
  fi
else
  echo "Directory not found"
fi

echo ""
echo "=== PROJECT-LEVEL SKILLS (.omc/skills/) ==="
if [ -d ".omc/skills" ]; then
  PROJECT_COUNT=$(find ".omc/skills" -name "*.md" 2>/dev/null | wc -l)
  echo "Total skills: $PROJECT_COUNT"

  if [ $PROJECT_COUNT -gt 0 ]; then
    echo ""
    echo "Skills found:"
    find ".omc/skills" -name "*.md" -type f -exec sh -c '
      FILE="$1"
      NAME=$(grep -m1 "^name:" "$FILE" 2>/dev/null | sed "s/name: //")
      DESC=$(grep -m1 "^description:" "$FILE" 2>/dev/null | sed "s/description: //")
      MODIFIED=$(stat -c "%y" "$FILE" 2>/dev/null || stat -f "%Sm" "$FILE" 2>/dev/null)
      echo "  - $NAME"
      [ -n "$DESC" ] && echo "    Description: $DESC"
      echo "    Modified: $MODIFIED"
      echo ""
    ' sh {} \;
  fi
else
  echo "Directory not found"
fi

# Summary
TOTAL=$((USER_COUNT + PROJECT_COUNT))
echo "=== SUMMARY ==="
echo "Total skills across all directories: $TOTAL"

Step 3: Quick Actions Menu

After scanning, use the AskUserQuestion tool to offer these options:

Question: "What would you like to do with your local skills?"

Options:

1. Add new skill - Start the skill creation wizard (invoke /skill add)
2. List all skills with details - Show comprehensive skill inventory (invoke /skill list)
3. Scan conversation for patterns - Analyze current conversation for skill-worthy patterns
4. Import skill - Import a skill from URL or paste content
5. Done - Exit the wizard

Option 3: Scan Conversation for Patterns

Analyze the current conversation context to identify potential skill-worthy patterns. Look for:

• Recent debugging sessions with non-obvious solutions
• Tricky bugs that required investigation
• Codebase-specific workarounds discovered
• Error patterns that took time to resolve

Report findings and ask if user wants to extract any as skills (invoke /skillify; /learner is deprecated compatibility).

Option 4: Import Skill

Ask user to provide either:

• URL: Download skill from a URL (e.g., GitHub gist)
• Paste content: Paste skill markdown content directly

Then ask for scope:

• User-level (~/.claude/skills/omc-learned/) - Available across all projects
• Project-level (.omc/skills/) - Only for this project

Validate the skill format and save to the chosen location.

/skill scan

Quick command to scan both skill directories (subset of /skill setup).

Behavior: Run the scan from Step 2 of /skill setup without the interactive wizard.

Skill Templates

When creating skills via /skill add or /skill setup, offer quick templates for common skill types:

Error Solution Template

Error Handling

All commands must handle:

• File/directory doesn't exist
• Permission errors
• Invalid YAML frontmatter
• Duplicate skill names
• Invalid skill names (spaces, special chars)

Error format:

✗ Error: <clear message>
→ Suggestion: <helpful next step>

Usage Examples

# List all skills
/skill list

# Create a new skill
/skill add my-custom-skill

# Remove a skill
/skill remove old-skill

# Edit existing skill
/skill edit error-handler

# Search for skills
/skill search typescript error

# Get detailed info
/skill info my-custom-skill

# Sync between scopes
/skill sync

# Run setup wizard
/skill setup

# Quick scan
/skill scan

Usage Modes

Direct Command Mode

When invoked with an argument, skip the interactive wizard:

• /oh-my-claudecode:skill list - Show detailed skill inventory
• /oh-my-claudecode:skill add - Start skill creation (invoke skillify)
• /oh-my-claudecode:skill scan - Scan both skill directories

Interactive Mode

When invoked without arguments, run the full guided wizard.

Benefits of Local Skills

Automatic Application: Claude detects triggers and applies skills automatically - no need to remember or search for solutions.

Version Control: Project-level skills (.omc/skills/) are intended to be committed with your code so the whole team benefits. In linked worktrees, uncommitted skills remain local to that worktree and disappear if it is removed.

Evolving Knowledge: Skills improve over time as you discover better approaches and refine triggers.

Reduced Token Usage: Instead of re-solving the same problems, Claude applies known patterns efficiently.

Codebase Memory: Preserves institutional knowledge that would otherwise be lost in conversation history.

Skill Quality Guidelines

Good skills are:

1. Non-Googleable - Can't easily find via search

   • BAD: "How to read files in TypeScript"
   • GOOD: "This codebase uses custom path resolution requiring fileURLToPath"

2. Context-Specific - References actual files/errors from THIS codebase

   • BAD: "Use try/catch for error handling"
   • GOOD: "The aiohttp proxy in server.py:42 crashes on ClientDisconnectedError"

3. Actionable with Precision - Tells exactly WHAT to do and WHERE

   • BAD: "Handle edge cases"
   • GOOD: "When seeing 'Cannot find module' in dist/, check tsconfig.json moduleResolution"

4. Hard-Won - Required significant debugging effort

   • BAD: Generic programming patterns
   • GOOD: "Race condition in worker.ts - Promise.all at line 89 needs await"

Related Skills

• /oh-my-claudecode:skillify - Extract a skill from current conversation (/oh-my-claudecode:learner is a deprecated alias)
• /oh-my-claudecode:note - Save quick notes (less formal than skills)
• /oh-my-claudecode:deepinit - Generate AGENTS.md codebase hierarchy

Tips for Users

• Run /oh-my-claudecode:skill list periodically to review your skill library
• After solving a tricky bug, immediately run skillify to capture it
• Use project-level skills for codebase-specific knowledge
• Use user-level skills for general patterns that apply everywhere
• Review and refine triggers over time to improve matching accuracy

Implementation Notes

1. YAML Parsing: Use frontmatter extraction for metadata
2. File Operations: Use Read/Write tools, never Edit for new files
3. User Confirmation: Always confirm destructive operations
4. Clear Feedback: Use checkmarks (✓), crosses (✗), arrows (→) for clarity
5. Scope Resolution: Always check both user and project scopes
6. Validation: Enforce naming conventions (lowercase, hyphens only)
