Skill

Skill Management CLI

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

Subcommands

/skill list

Show all local skills organized by scope.

Behavior:

1. Scan user skills at ~/.gemini-cli/skills/omc-learned/
2. Scan project skills at .omc/skills/
3. Parse YAML frontmatter for metadata
4. Display in organized table format:

USER SKILLS (~/.gemini-cli/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"

/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 → ~/.gemini-cli/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-gemini: example-arg

## Notes

[Additional context, edge cases, gotchas]

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

Example:

User: /skill add custom-logger
Assistant: Creating new skill 'custom-logger'...

Description: Enhanced logging with structured output
Triggers (comma-separated): log, logger, logging
Argument hint (optional): <level> [message]
Scope (user/project): user

✓ Created skill at ~/.gemini-cli/skills/omc-learned/custom-logger/SKILL.md
→ Edit with: /skill edit custom-logger

/skill remove

Remove a skill by name.

Behavior:

1. Search for skill in both scopes:
   • ~/.gemini-cli/skills/omc-learned/<name>/SKILL.md
   • .omc/skills/<name>/SKILL.md
2. If found:
   • Display skill info (name, description, scope)
   • Ask for confirmation: "Delete '' skill from ? (yes/no)"
3. If confirmed:
   • Delete entire skill directory (e.g., ~/.gemini-cli/skills/omc-learned/<name>/)
   • Report: "✓ Removed skill '' from "
4. If not found:
   • Report: "✗ Skill '' not found in user or project scope"

Safety: Never delete without explicit user confirmation.

Example:

User: /skill remove old-logger
Assistant: Found skill 'old-logger' in user scope:
  Description: Legacy logging utility
  Scope: user (~/.gemini-cli/skills/omc-learned/)

Delete 'old-logger' skill? (yes/no)

Behavior:

1. Find skill by name (search both scopes)
2. Read current content via Read tool
3. Display current values:

   Current skill 'custom-logger':
   - Description: Enhanced logging with structured output
   - Triggers: log, logger, logging
   - Argument hint: <level> [message]
   - Scope: user
   

4. Ask what to change:
   • description - Update description
   • triggers - Update trigger keywords
   • argument-hint - Update argument hint
   • content - Edit full markdown content

   • cancel - Exit without changes
5. For selected field:
   • Show current value
   • Ask for new value
   • Update YAML frontmatter or content
   • Write back to file
6. Report success with summary of changes

Example:

User: /skill edit custom-logger

✓ Updated triggers for 'custom-logger'

/skill search

Search skills by content, triggers, name, or description.

Behavior:

1. Scan all skills in both scopes
2. Match query (case-insensitive) against:
   • Skill name
   • Description
   • Triggers
   • Full markdown content
3. Display matches with context:

/skill sync

Sync skills between user and project scopes.

Behavior:

1. Scan both scopes:
   • User skills: ~/.gemini-cli/skills/omc-learned/
   • Project skills: .omc/skills/
2. Compare and categorize:
   • User-only skills (not in project)
   • Project-only skills (not in user)
   • Common skills (in both)
3. Display sync opportunities:

SYNC REPORT:

User-only skills (5):
  - error-handler
  - api-builder
  - custom-logger
  - test-generator
  - deploy-helper

Project-only skills (2):
  - test-runner
  - backend-scaffold

Common skills (3):
  - frontend-ui-ux
  - git-master
  - planner

Options:
  [1] Copy user skill to project
  [2] Copy project skill to user
  [3] View differences
  [4] Cancel

4. Handle user choice:
   • Option 1: Select skill(s) to copy to project
   • Option 2: Select skill(s) to copy to user
   • Option 3: Show side-by-side diff for common skills
   • Option 4: Exit

Safety: Never overwrite without confirmation

Example:

User: /skill sync
Assistant: Found 5 user-only skills and 2 project-only skills.

Copy 'error-handler' from user to project? (yes/no/skip)
User: yes
Assistant: ✓ Copied 'error-handler' to .omc/skills/

Copy 'api-builder' from user to project? (yes/no/skip)
User: skip
...

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

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)

Future Enhancements

• /skill export <name> - Export skill as shareable file
• /skill import <file> - Import skill from file
• /skill stats - Show usage statistics across all skills
• /skill validate - Check all skills for format errors
• /skill template <type> - Create from predefined templates
