Simple Skills Manager

Manage skill tips in ~/.claude/skills/ that point to skills from local paths or git repositories, enabling dynamic invocation via /{group}-{skill-name}.

Note: We use hyphen - as separator instead of colon : because Windows paths don't support colons in filenames.

Constants

• Repos directory: ~/.claude/simple-skills-manager-repos/
• Skills directory: ~/.claude/skills/
• Backup directory: ~/.claude/simple-skills-manager-backup-last-skills/

Workflow

Step 1: Ask Operation Type

First, ask the user what operation they want to perform:

{
  "questions": [{
    "question": "What operation would you like to perform?",
    "header": "Operation",
    "options": [
      {"label": "Add (Recommended)", "description": "Add skills from a local path or git repository"},
      {"label": "Update", "description": "Update an existing skill group (re-sync from source)"},
      {"label": "Remove", "description": "Remove an existing skill group"}
    ],
    "multiSelect": false
  }]
}

Step 2: Collect Information Based on Operation

For "Add" Operation

Ask user to directly input the source path or git URL:

{
  "questions": [{
    "question": "Please enter the local path or git URL for the skills:",
    "header": "Source",
    "options": [
      {"label": "Example: /path/to/skills", "description": "Local directory containing SKILL.md files"},
      {"label": "Example: https://github.com/user/repo.git", "description": "Git repository URL (will be cloned)"}
    ],
    "multiSelect": false
  }]
}

The user will select "Other" and type the actual path or URL. The system will auto-detect the source type:

• Git URL: starts with http://, https://, git@, or ends with .git
• Local path: everything else (treat as filesystem path)

After getting the source, ask for the group name:

{
  "questions": [{
    "question": "What group name should be used as prefix? (e.g., 'mygroup' creates '/mygroup-skill-name')",
    "header": "Group",
    "options": [
      {"label": "Use folder name", "description": "Use the source folder/repo name as group"},
      {"label": "Custom", "description": "Enter a custom group name"}
    ],
    "multiSelect": false
  }]
}

Group name validation: The group name must:

• Only contain lowercase letters, numbers, and hyphens (a-z, 0-9, -)
• Not start or end with a hyphen
• Not be empty
• Not contain spaces, slashes, asterisks, or other special characters

If the group name is invalid, ask the user to provide a valid name.

For "Update" or "Remove" Operation

First, list existing groups by checking subdirectories in repos directory:

# List groups from repos directory (source of truth for groups)
ls -d ~/.claude/simple-skills-manager-repos/*/ 2>/dev/null | xargs -I {} basename {}

Important: Groups are determined by subdirectories in ~/.claude/simple-skills-manager-repos/, NOT by folder names in skills directory.

Display the found groups as reference information, then ask the user to input the group name they want to manage:

{
  "questions": [{
    "question": "Which group do you want to update/remove? (Enter the group name)",
    "header": "Group",
    "options": [
      {"label": "Example: mygroup", "description": "Enter the group name you want to manage"},
      {"label": "Example: arcblock", "description": "The group prefix used in skill names like /arcblock-commit"}
    ],
    "multiSelect": false
  }]
}

The user will select "Other" and type the actual group name. Validate that the group exists by checking if ~/.claude/simple-skills-manager-repos/{group}/ directory exists before proceeding.

Step 3: Backup Before Operation (Required)

Before executing any Add, Update, or Remove operation, you MUST backup the current skills directory:

# Remove old backup if exists, then create new backup
rm -rf ~/.claude/simple-skills-manager-backup-last-skills
cp -r ~/.claude/skills ~/.claude/simple-skills-manager-backup-last-skills

This ensures the user can recover their skills if something goes wrong.

Step 4: Execute Operation

Add Operation

1. Verify and prepare source:

   • If local path: Verify the path exists first, then create group directory

     mkdir -p ~/.claude/simple-skills-manager-repos/{group}
     echo "{absolute-working-path}" > ~/.claude/simple-skills-manager-repos/{group}/path.txt
     

   • If git URL:
     • If group directory already exists and has .git, run git pull instead:

       git -C ~/.claude/simple-skills-manager-repos/{group} pull
       

     • Otherwise, clone to ~/.claude/simple-skills-manager-repos/{group}/:

       git clone {git-url} ~/.claude/simple-skills-manager-repos/{group}
       

     • If clone/pull fails, stop and report error - do not proceed

2. Determine working path:

   • Local path: use the path from user input
   • Git URL: use ~/.claude/simple-skills-manager-repos/{group}/

3. Scan for skills in the working path:

   find "{working-path}" -name "SKILL.md" -type f 2>/dev/null
   

   • If no SKILL.md found, stop and report error - do not proceed

4. Clean existing tips for this group (if group already exists):

   • Read ~/.claude/simple-skills-manager-repos/{group}/skill-names.txt if it exists
   • Delete each skill listed in the file:

     # For each skill-name in skill-names.txt
     rm -rf ~/.claude/skills/{skill-name}
     

5. Create skill tips for each SKILL.md found (see "Creating Skill Tips" section)

6. Save skill manifest - write all created skill names to skill-names.txt:

   # Write skill names (one per line) to skill-names.txt
   echo "{group}-{skill-name-1}" > ~/.claude/simple-skills-manager-repos/{group}/skill-names.txt
   echo "{group}-{skill-name-2}" >> ~/.claude/simple-skills-manager-repos/{group}/skill-names.txt
   # ... for each skill
   

   Example skill-names.txt content:

   my-commit
   my-deploy
   my-test
   

7. Report results

Update Operation

1. Verify group exists:

   • Check if ~/.claude/simple-skills-manager-repos/{group}/ directory exists
   • If not exists, stop and report error - group not found

2. Determine source type and pull latest:

   • Git source: Check if it's a git repo (has .git directory)

     test -d ~/.claude/simple-skills-manager-repos/{group}/.git && echo "git" || echo "local"
     

     • If git repo, run git pull first:

       git -C ~/.claude/simple-skills-manager-repos/{group} pull
       

     • Working path: ~/.claude/simple-skills-manager-repos/{group}/
   • Local path source: Check if path.txt exists in the group directory

     cat ~/.claude/simple-skills-manager-repos/{group}/path.txt
     

     • If exists, read the original path from it
     • If path.txt not found, ask user to provide the source path
     • Working path: the path from path.txt or user input

3. Scan for skills in the working path:

   find "{working-path}" -name "SKILL.md" -type f 2>/dev/null
   

   • If no SKILL.md found, stop and report error - do not proceed

4. Clean existing tips using skill manifest (if exists):

   • Read ~/.claude/simple-skills-manager-repos/{group}/skill-names.txt if it exists
   • Delete each skill listed in the file:

     # For each skill-name in skill-names.txt
     rm -rf ~/.claude/skills/{skill-name}
     

5. Recreate skill tips for each SKILL.md found (see "Creating Skill Tips" section)

6. Update skill manifest - overwrite skill-names.txt with new skill names

7. Report results (include git pull output if applicable)

Remove Operation

1. Verify group exists:

   • Check if ~/.claude/simple-skills-manager-repos/{group}/ directory exists
   • If not exists, stop and report error - group not found

2. Remove skill tips using skill manifest (if exists):

   • Read ~/.claude/simple-skills-manager-repos/{group}/skill-names.txt if it exists
   • Delete each skill listed in the file:

     # For each skill-name in skill-names.txt
     rm -rf ~/.claude/skills/{skill-name}
     

3. Remove group directory from repos:

   rm -rf ~/.claude/simple-skills-manager-repos/{group}
   

4. Report results

Creating Skill Tips

For each SKILL.md found, extract:

1. Skill name: From name: field in frontmatter, or from parent directory name
2. Description: From description: field in frontmatter
3. Allowed tools: From allowed-tools: field in frontmatter

Create directory and SKILL.md in ~/.claude/skills/{group}-{skill-name}/SKILL.md:

mkdir -p ~/.claude/skills/{group}-{skill-name}

Generated SKILL.md format:

---
name: {group}-{skill-name}
description: {original-description}
allowed-tools:
  - Read
  - Glob
  - Grep
  {... copy remaining allowed-tools from original skill, excluding duplicates}
---

# {group}-{skill-name}

This is a tip pointing to a skill from external source.

## Instructions

**IMPORTANT**: Read and execute the skill from the following path:

{absolute-path-to-original-SKILL.md}

Use the Read tool to load the actual skill content, then follow all instructions in that file.

Note: When copying allowed-tools, always include Read, Glob, Grep first (required for tip to work), then add any additional tools from the original skill that are not already listed.

Notes

• Backup directory: ~/.claude/simple-skills-manager-backup-last-skills/ - created before each operation
• Repos directory structure:
  • Git sources: ~/.claude/simple-skills-manager-repos/{group}/ (contains .git + skill-names.txt)
  • Local sources: ~/.claude/simple-skills-manager-repos/{group}/ (contains path.txt + skill-names.txt)
• Skill manifest: skill-names.txt stores exact skill folder names (one per line), used for precise deletion/update
• Group detection: Groups are identified by subdirectories in ~/.claude/simple-skills-manager-repos/, NOT by skill folder names
• Naming convention: Skills use hyphen - as separator (e.g., {group}-{skill-name}) for Windows compatibility
• Local path sources are referenced directly, not copied
• Tips dynamically load content, so changes to original skills are reflected immediately
• Each group's tips are managed independently
• The original skill files are never modified
• Skills are loaded at startup - restart Claude Code after adding/updating skills
