 description: >
  Manages syncing, updating, and sharing Claude skills via Helloprint's GitLab repositories. Use this
  skill whenever a user mentions: syncing skills, updating skills, pulling new skills, pushing skill
  changes, git conflicts in skills, sharing a skill, publishing a skill, "my skills are outdated",
  "get latest skills", "save my skill changes", "skill sync", "skill update", or any reference to
  git operations in the context of Claude skills. Also trigger when users mention skill repos, skill
  repositories, or ask how to get new skills that were shared with them. This skill is designed for
  non-technical users who should never need to understand git commands directly.

 # Skills Sync
 A friendly skill that handles all git operations for Claude skills behind the scenes. The user
 should never need to type a git command — Claude does everything and explains what happened in
 plain language.
 ## Important Principles
 1. **Never show raw git output** to the user unless they ask for it or something goes wrong
 2. **Use simple language**: "download latest changes" not "git pull", "save your work" not "commit"
 3. **Always confirm before pushing** — the user should approve before changes go to the team
 4. **Handle conflicts gracefully** — explain what happened and offer clear choices
 5. **Protect secrets** — never commit `.env` files or anything matching secret patterns
 ## GitLab Configuration
 All skill repositories are hosted on Helloprint's GitLab instance. The URL pattern is:
 ```
 git@gitlab.it.helloprint.com:ai-and-automation/claude-skills/skills-{process}.git
 ```
 ### Helloprint Value Chain Repositories
 Repos are organized around Helloprint's core value chain processes, not departments:
 | Process                    | Lead    | Repository             |
 |----------------------------|---------|------------------------|
 | (Shared — everyone)        | —       | skills-shared          |
 | Source Products             | Rick    | skills-source-products |
 | Add Products                | Rick    | skills-add-products    |
 | Sell Products & Services    | Niels   | skills-sell-products   |
 | Deliver Products            | Rick    | skills-deliver-products|
 | Get Paid & Be Compliant    | Lennart | skills-get-paid        |
 | Serve Customers             | Maarten | skills-serve-customers |
 Full SSH URLs:

 - `git@gitlab.it.helloprint.com:ai-and-automation/claude-skills/skills-serve-customers.git`
 > **Note**: Some people work across multiple processes (e.g., Rick leads Source, Add, and Deliver).
 > During setup, ask the user which process(es) they work in — they may need access to more than one repo.
 ### GitLab web interface
 To browse skills online:
 ```
 https://gitlab.it.helloprint.com/ai-and-automation/claude-skills/skills-{process}
 ```
 ## Expected Directory Layout
 ```
 /mnt/skills/user/
 ├── .skills-sync.json              # Config file this skill creates
 ├── shared/                        # Cloned from skills-shared
 │   ├── .git/
 │   └── (shared skills...)
 ├── source-products/               # Cloned from skills-source-products
 │   ├── .git/
 │   └── (process skills...)
 ├── sell-products/                 # Cloned from skills-sell-products
 │   ├── .git/
 │   └── (process skills...)
 └── my-custom-skill/               # Local skill, not git-managed
 ```
 ### First-time setup
 If `.skills-sync.json` doesn't exist, walk the user through setup:
 1. Ask for their name and email
 2. Ask which process(es) they work in — show the list of six processes
   - People may work in more than one process (e.g., Rick works in Source, Add, and Deliver)
 3. Confirm the repos — everyone gets `skills-shared` plus their process repo(s)
 4. Check that SSH access works: `ssh -T git@gitlab.it.helloprint.com`
   - If this fails, tell the user: "It looks like your SSH key isn't set up for GitLab yet. Ask IT to help you set up an SSH key."
 5. Clone each repo into `/mnt/skills/user/`
 6. Configure git user name and email
 7. Create `.skills-sync.json` to remember the setup
 ```json
 {
  "gitlab_host": "gitlab.it.helloprint.com",
  "gitlab_group": "ai-and-automation/claude-skills",
  "repos": [
    {
      "name": "Shared Skills",
      "path": "/mnt/skills/user/shared",
      "remote_url": "git@gitlab.it.helloprint.com:ai-and-automation/claude-skills/skills-shared.git",
      "branch": "main",
      "access": "read-only"
    },
    {
      "name": "Sell Products & Services",
      "path": "/mnt/skills/user/sell-products",
      "remote_url": "git@gitlab.it.helloprint.com:ai-and-automation/claude-skills/skills-sell-products.git",
      "branch": "main",
      "access": "read-write"
    }
  ],
  "user": {
    "name": "Niels",
    "email": "niels@helloprint.com"
  },
  "secrets_patterns": [".env", "*.key", "*.pem", "*.secret", "*credentials*"],
  "last_sync": "2026-02-27T10:00:00Z"
 }
 ```
 ## Core Operations
 ### 1. Get Latest Skills ("sync" / "update")
 **Trigger phrases**: "update my skills", "get latest", "sync", "are my skills up to date?"
 ```bash
 # For each repo in config:
 cd <repo_path>
 # Stash any local changes first
 git stash
 # Pull latest
 git pull origin <branch>
 # Re-apply local changes if any
 git stash pop
 ```
 **Tell the user**:
 - "Your skills are up to date! I pulled the latest changes from [N] skill repos."
 - If there were updates: "Updated skills: [list skill folder names that changed]"
 - If there were conflicts: move to conflict resolution (see below)
 ### 2. Save & Share Changes ("push" / "share" / "publish")
 **Trigger phrases**: "save my changes", "share this skill", "push my updates", "publish"
 **Steps**:
 1. Run `git status` to see what changed
 2. Summarize changes in plain language: "You've modified the **order-tracking** skill (changed 2 files) and created a new **supplier-outreach** skill."
 3. **Ask for confirmation**: "Would you like to share these changes with your team?"
 4. Check for secrets before committing (see Security section)
 5. If confirmed:
 ```bash
 cd <repo_path>
 git add -A
 git commit -m "<auto-generated descriptive message>"
 git pull origin <branch> --rebase
 git push origin <branch>
 ```
 6. Tell the user: "Your changes are now shared with the team!"
 **Auto-generate commit messages** that are descriptive:
 - "Update order-tracking: added carrier integration for DPD"
 - "Add new skill: supplier-outreach for automated follow-ups"
 - "Fix invoice-processor: corrected VAT calculation logic"
 ### 3. Resolve Conflicts
 **When this happens**: Two people edited the same file. Git can't merge automatically.
 **Approach for non-technical users**:
 1. Detect the conflict after a pull
 2. Read both versions (theirs and ours)
 3. Explain in plain language: "It looks like both you and a colleague changed the **order-tracking** skill. Here's what's different: [summary of differences]"
 4. Offer clear choices:
   - **"Keep my version"** — uses the user's changes, discards the other
   - **"Keep the team's version"** — uses what the team pushed, discards local changes
   - **"Merge both"** — Claude intelligently combines both changes and shows the result for approval
 5. After the user chooses, resolve the conflict and complete the merge
 ```bash
 # After resolving:
 git add <resolved_files>
 git commit -m "Resolve conflict in <skill-name>: kept [user's choice]"
 git push origin <branch>
 ```
 ### 4. Check Status
 **Trigger phrases**: "what's changed", "skill status", "any updates available"
 Run `git status` and `git log --oneline -5` on each repo. Summarize:
 - Local changes not yet shared
 - How many updates are available from the team
 - When the last sync happened
 Present as a simple summary, e.g.:
 "Here's the status of your skill repos:
 - **Shared Skills**: Up to date (last synced 2 hours ago)
 - **Sell Products**: You have 2 unsaved changes. The team pushed 3 updates since your last sync."
 ### 5. View History
 **Trigger phrases**: "who changed this skill", "what changed recently", "skill history"
 ```bash
 git log --oneline --since="2 weeks ago" --pretty=format:"%h %an: %s (%ar)"
 ```
 Present as a readable timeline:
 "Recent changes to **Sell Products** skills:
 - Niels updated lead-qualifier (2 days ago)
 - Anna added quote-generator (5 days ago)
 - Niels fixed email-templates CSV handling (1 week ago)"
 ### 6. Create a Merge Request (optional advanced workflow)
 **Trigger phrases**: "create a merge request", "submit for review", "MR"
 If the team uses GitLab merge requests instead of direct pushes:
 1. Create a feature branch: `git checkout -b skill/<skill-name>-update`
 2. Commit changes to the branch
 3. Push the branch: `git push origin skill/<skill-name>-update`
 4. Provide the user with a link to create the MR on GitLab:
   `https://gitlab.it.helloprint.com/ai-and-automation/claude-skills/skills-<process>/-/merge_requests/new?merge_request[source_branch]=skill/<skill-name>-update`
 5. Tell the user: "I've prepared your changes for review. Click the link to open the merge request in GitLab, then hit 'Create merge request'."
 ## Security: Handling Secrets
 ### Pre-commit Secret Check
 **ALWAYS run this before any commit.** Scan staged files for:
 ```python
 import re
 SECRET_PATTERNS = [
    r'(?i)(api[_-]?key|apikey)\s*[=:]\s*["\']?[\w-]{20,}',
    r'(?i)(secret|password|passwd|pwd)\s*[=:]\s*["\']?[^\s"\']{8,}',
    r'(?i)(token)\s*[=:]\s*["\']?[\w-]{20,}',
    r'sk-[a-zA-Z0-9]{20,}',           # OpenAI-style keys
    r'ghp_[a-zA-Z0-9]{36}',           # GitHub PATs
    r'glpat-[\w-]{20,}',              # GitLab personal access tokens
    r'xox[bpras]-[\w-]+',             # Slack tokens
    r'-----BEGIN [\w ]+ KEY-----',     # Private keys
    r'(?i)bearer\s+[\w-]{20,}',       # Bearer tokens
 ]
 ```
 **If secrets are found**:
 1. **STOP** — do not commit
 2. Tell the user: "I found what looks like a secret key in [filename]. I won't share this to protect your security."
 3. Suggest: "You should move secrets to a `.env` file (which is git-ignored) or use the company's secret manager."
 ### .gitignore
 Ensure every skills repo has a `.gitignore` with:
 ```
 .env
 .env.*
 *.key
 *.pem
 *.secret
 *credentials*
 .skills-sync.json
 __pycache__/
 .DS_Store
 ```
 ### Recommended Secrets Approach
 **For API keys and tokens used inside skills**, use this pattern:
 1. Skills reference environment variables: `os.environ.get("API_KEY")`
 2. Each user has a local `.env` file (git-ignored) with their keys
 3. A `.env.example` file IS committed, showing required variables without values:
   ```
   # Required API keys for this skill
   OPENAI_API_KEY=your-key-here
   SLACK_WEBHOOK_URL=your-url-here
   ```
 4. When a user clones a skill repo, Claude helps them create their `.env` from the example
 5. Actual key values are distributed through a secure channel (password manager, not Slack/email)
 ## Error Handling
 | Error | User-friendly message |
 |-------|----------------------|
 | SSH auth failed | "I can't connect to GitLab. Your SSH key may not be set up yet — ask IT for help." |
 | Repo not found | "The skills repo doesn't seem to exist at that address. Can you double-check with your process lead?" |
 | Permission denied (push) | "You don't have permission to share changes to this repo. It might be read-only for your role, or you may need to create a merge request instead." |
 | Network error | "I can't reach GitLab right now. Check your internet/VPN connection and try again." |
 | Merge conflict | Move to conflict resolution flow (Section 3 above) |
 | Detached HEAD | Silently fix with `git checkout main` before proceeding |
 ## Tone Guide
 - "I'll download the latest skills from your team" (not "git pull from origin")
 - "Save and share your changes" (not "commit and push")
 - "Someone else also edited this file" (not "merge conflict detected")
 - "Your skills are up to date!" (not "Already up to date. On branch main.")
 - "I'll prepare this for review on GitLab" (not "push to remote branch and open MR")
