This skill provides a guided wizard for setting up and managing your local learned skills. Skills are reusable problem-solving patterns that Claude automatically applies when it detects matching triggers.

Why Local Skills?

Local skills allow you to capture hard-won insights and solutions that are specific to your codebase or workflow:

Project-level skills (.omc/skills/) - Version-controlled with your repo
User-level skills (~/.gemini-cli/skills/omc-learned/) - Portable across all your projects

When you solve a tricky bug or discover a non-obvious workaround, you can extract it as a skill. Claude will automatically detect and apply these skills in future conversations when it sees matching triggers.

Interactive Workflow

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="$HOME/.gemini-cli/skills/omc-learned"
if [ -d "$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 (~/.gemini-cli/skills/omc-learned/) ==="
if [ -d "$HOME/.gemini-cli/skills/omc-learned" ]; then
  USER_COUNT=$(find "$HOME/.gemini-cli/skills/omc-learned" -name "*.md" 2>/dev/null | wc -l)
  echo "Total skills: $USER_COUNT"

  if [ $USER_COUNT -gt 0 ]; then
    echo ""
    echo "Skills found:"
    find "$HOME/.gemini-cli/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:

Add new skill - Start the skill creation wizard
List all skills with details - Show comprehensive skill inventory with triggers
Scan conversation for patterns - Analyze current conversation for skill-worthy patterns
Import skill - Import a skill from URL or paste content
Done - Exit the wizard

Option 1: Add New Skill

If user chooses "Add new skill", invoke the learner skill:

Use the Skill tool to invoke: learner

This will guide them through the extraction process with quality validation.

Option 2: List All Skills with Details

Show detailed information including trigger keywords:

echo "=== DETAILED SKILL INVENTORY ==="
echo ""

# Function to show skill details
show_skill_details() {
  FILE="$1"
  LOCATION="$2"

  echo "---"
  echo "Location: $LOCATION"
  echo "File: $(basename "$FILE")"

  # Extract frontmatter
  NAME=$(grep -m1 "^name:" "$FILE" 2>/dev/null | sed "s/name: //")
  DESC=$(grep -m1 "^description:" "$FILE" 2>/dev/null | sed "s/description: //")
  TRIGGERS=$(grep -m1 "^triggers:" "$FILE" 2>/dev/null | sed "s/triggers: //")
  QUALITY=$(grep -m1 "^quality:" "$FILE" 2>/dev/null | sed "s/quality: //")

  [ -n "$NAME" ] && echo "Name: $NAME"
  [ -n "$DESC" ] && echo "Description: $DESC"
  [ -n "$TRIGGERS" ] && echo "Triggers: $TRIGGERS"
  [ -n "$QUALITY" ] && echo "Quality: $QUALITY"

  # Last modified
  MODIFIED=$(stat -c "%y" "$FILE" 2>/dev/null | cut -d. -f1 || stat -f "%Sm" "$FILE" 2>/dev/null)
  echo "Last modified: $MODIFIED"
  echo ""
}

# Export function for subshell
export -f show_skill_details

# Show user-level skills
if [ -d "$HOME/.gemini-cli/skills/omc-learned" ]; then
  echo "USER-LEVEL SKILLS:"
  find "$HOME/.gemini-cli/skills/omc-learned" -name "*.md" -type f -exec bash -c 'show_skill_details "$0" "user-level"' {} \;
fi

# Show project-level skills
if [ -d ".omc/skills" ]; then
  echo "PROJECT-LEVEL SKILLS:"
  find ".omc/skills" -name "*.md" -type f -exec bash -c 'show_skill_details "$0" "project-level"' {} \;
fi

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.

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 (~/.gemini-cli/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.

Step 4: Skill Templates

Provide quick templates for common skill types. When user wants to create a skill, offer these starting points:

Error Solution Template

---
id: error-[unique-id]
name: [Error Name]
description: Solution for [specific error in specific context]
source: conversation
triggers: ["error message fragment", "file path", "symptom"]
quality: high
---

# [Error Name]

## The Insight
What is the underlying cause of this error? What principle did you discover?

## Why This Matters
What goes wrong if you don't know this? What symptom led here?

## Recognition Pattern
How do you know when this applies? What are the signs?
- Error message: "[exact error]"
- File: [specific file path]
- Context: [when does this occur]

## The Approach
Step-by-step solution:
1. [Specific action with file/line reference]
2. [Specific action with file/line reference]
3. [Verification step]

## Example
\`\`\`typescript
// Before (broken)
[problematic code]

// After (fixed)
[corrected code]
\`\`\`

Skill Quality Guidelines

Remind users that good skills are:

Non-Googleable - Can't easily find via search
- BAD: "How to read files in TypeScript" ❌
- GOOD: "This codebase uses custom path resolution requiring fileURLToPath" ✓
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" ✓
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" ✓
Hard-Won - Required significant debugging effort
- BAD: Generic programming patterns ❌
- GOOD: "Race condition in worker.ts - Promise.all at line 89 needs await" ✓

Benefits of Local Skills

When introducing the skill system, explain these benefits:

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 committed with your code, so the whole team benefits.

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.
