+name: skillshare
+version: 0.6.4
+description: Syncs skills across AI CLI tools from a single source of truth. Use when asked to "sync skills", "pull skills", "show status", "list skills", "install skill", "initialize skillshare", or manage skill targets.
+argument-hint: "[command] [target] [--dry-run]"
+---
+
+# Skillshare CLI
+
+```
+Source: ~/.config/skillshare/skills  ← Edit here (single source of truth)
+         ↓ sync
+Targets: ~/.claude/skills, ~/.cursor/skills, ...  ← Symlinked from source
+```
+
+## Quick Reference
+
+```bash
+skillshare status              # Always run first
+skillshare sync                # Push to all targets
+skillshare sync --dry-run      # Preview changes
+skillshare pull claude         # Import from target → source
+skillshare list                # Show skills and tracked repos
+```
+
+## Command Patterns
+
+| Intent | Command |
+|--------|---------|
+| Sync skills | `skillshare sync` |
+| Preview first | `skillshare sync --dry-run` then `sync` |
+| Create new skill | `skillshare new <name>` then `sync` |
+| Pull from target | `skillshare pull <name>` then `sync` |
+| Install skill | `skillshare install <source>` then `sync` |
+| Install from repo (browse) | `skillshare install owner/repo` (discovery mode) |
+| Install team repo | `skillshare install <git-url> --track` then `sync` |
+| Update skill/repo | `skillshare update <name>` then `sync` |
+| Update all tracked | `skillshare update --all` then `sync` |
+| Remove skill | `skillshare uninstall <name>` then `sync` |
+| List skills | `skillshare list` or `list --verbose` |
+| Cross-machine push | `skillshare push -m "message"` |
+| Cross-machine pull | `skillshare pull --remote` |
+| Backup/restore | `skillshare backup --list`, `restore <target>` |
+| Add custom target | `skillshare target add <name> <path>` |
+| Change sync mode | `skillshare target <name> --mode merge\|symlink` |
+| Upgrade CLI/skill | `skillshare upgrade` |
+| Diagnose issues | `skillshare doctor` |
+
+## Init (Non-Interactive)
+
+**CRITICAL:** Use flags — AI cannot respond to CLI prompts.
+
+**Source path:** Always use default `~/.config/skillshare/skills`. Only use `--source` if user explicitly requests a different location.
+
+**Step 1:** Check existing skills
+```bash
+ls ~/.claude/skills ~/.cursor/skills 2>/dev/null | head -10
+```
+
+**Step 2:** Run init based on findings
+
+| Found | Command |
+|-------|---------|
+| Skills in one target | `skillshare init --copy-from <name> --all-targets --git` |
+| Skills in multiple | Ask user which to import |
+| No existing skills | `skillshare init --no-copy --all-targets --git` |
+
+**Step 3:** `skillshare status`
+
+**Adding new agents later (AI must use --select):**
+```bash
+skillshare init --discover --select "windsurf,kilocode"   # Non-interactive (AI use this)
+# skillshare init --discover                              # Interactive only (NOT for AI)
+```
+
+See [init.md](references/init.md) for all flags.
+
+## Team Edition
+
+```bash
+skillshare install github.com/team/skills --track   # Install as tracked repo
+skillshare update _team-skills                       # Update later
+```
+
+Tracked repos: `_` prefix, nested paths use `__` (e.g., `_team__frontend__ui`).
+
+**Naming convention:** Use `{team}:{name}` in SKILL.md to avoid collisions.
+
+## Safety
+
+- **NEVER** `rm -rf` on symlinked skills — deletes source
+- Use `skillshare uninstall <name>` to safely remove
+
+## Zero-Install
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/runkids/skillshare/main/skills/skillshare/scripts/run.sh | sh -s -- status
+```

+# Skillshare Troubleshooting
+
+Common issues, solutions, and tips for AI assistants.
+
+## Common Issues
+
+| Problem | Diagnosis | Solution |
+|---------|-----------|----------|
+| "config not found" | Config missing | Run `skillshare init` |
+| Target shows differences | Files out of sync | Run `skillshare sync` |
+| Lost source files | Deleted via symlink | `cd ~/.config/skillshare/skills && git checkout -- <skill>/` |
+| Target has local skills | Need to preserve | Ensure `merge` mode, then `skillshare pull` before sync |
+| Skill not appearing | Not synced yet | Run `skillshare sync` after install |
+| Can't find installed skills | Wrong directory | Check `skillshare status` for source path |
+| "permission denied" | Symlink issues | Check file ownership and permissions |
+| Git remote not set | Push fails | Run `git remote add origin <url>` in source |
+
+## Recovery Workflow
+
+When something goes wrong:
+
+```bash
+skillshare doctor          # 1. Diagnose issues
+skillshare backup          # 2. Create safety backup
+skillshare sync --dry-run  # 3. Preview fix
+skillshare sync            # 4. Apply fix
+```
+
+## Git Recovery
+
+If source files were accidentally deleted:
+
+```bash
+cd ~/.config/skillshare/skills
+git status                     # See what's missing
+git checkout -- <skill-name>/  # Restore specific skill
+git checkout -- .              # Restore all deleted files
+```
+
+If you need to restore from backup:
+
+```bash
+skillshare backup --list               # List available backups
+skillshare restore claude --from <timestamp>
+```
+
+## Tips for AI Assistants
+
+### Symlink Behavior
+
+Understanding symlinks is critical:
+
+1. **merge mode** (default): Each skill in target is a symlink to source
+   - Editing `~/.claude/skills/my-skill/SKILL.md` edits the source
+   - Changes are immediate and affect all targets
+   - Safe: `skillshare uninstall my-skill`
+   - **DANGEROUS**: `rm -rf ~/.claude/skills/my-skill` - deletes source!
+
+2. **symlink mode**: Entire target directory is a symlink
+   - `~/.claude/skills` → `~/.config/skillshare/skills`
+   - All targets are identical
+   - No local skills possible
+
+### When to Use --dry-run
+
+Always use `--dry-run` in these situations:
+
+- User is cautious or new to skillshare
+- Before `sync` on first use
+- Before `pull --all` to see what will be imported
+- Before `install` from unknown sources
+- Before `restore` to preview what will change
+- Before `target remove` to understand impact
+
+### Safe vs Dangerous Operations
+
+**Safe operations:**
+```bash
+skillshare target remove <name>     # Removes symlinks, keeps source
+skillshare uninstall <name>         # Removes skill properly
+skillshare sync                     # Creates/updates symlinks
+```
+
+**NEVER do this:**
+```bash
+rm -rf ~/.claude/skills/my-skill    # Deletes source via symlink!
+rm -rf ~/.claude/skills             # May delete entire source!
+```
+
+### Creating New Skills
+
+Guide users to create skills in source:
+
+1. Create directory: `~/.config/skillshare/skills/<skill-name>/`
+2. Create `SKILL.md` with required frontmatter:
+   ```yaml
+   ---
+   name: skill-name
+   description: What this skill does
+   ---
+   ```
+3. Run `skillshare sync` to distribute
+
+### Git Workflow Reminders
+
+After any skill changes, remind user to push:
+
+```bash
+skillshare push                    # Simple: commit + push
+skillshare push -m "Add new skill" # With custom message
+```
+
+### Handling Init Prompts
+
+AI cannot respond to CLI prompts. When user asks to initialize:
+
+1. Ask clarifying questions in chat
+2. Build the command with appropriate flags
+3. Run non-interactively
+
+Example conversation:
+- AI: "Do you have existing skills to copy from Claude or another tool?"
+- User: "Yes, from Claude"
+- AI: "Which CLI tools should I set up as targets?"
+- User: "Claude and Cursor"
+- AI: "Should I initialize git for version control?"
+- User: "Yes"
+- AI runs: `skillshare init --copy-from claude --targets "claude,cursor" --git`
+
+### Debugging Sync Issues
+
+If sync seems stuck or wrong:
+
+```bash
+skillshare status        # Check current state
+skillshare diff          # See actual differences
+ls -la ~/.claude/skills  # Check symlink targets
+```
+
+Look for:
+- Broken symlinks (pointing to non-existent files)
+- Regular files instead of symlinks
+- Wrong symlink targets

+# Init Command
+
+Initializes skillshare configuration.
+
+## Key Concept
+
+**Source is always `~/.config/skillshare/skills`** — never a CLI directory like `.claude/skills`.
+
+- `--copy-from claude` = import skills FROM claude INTO source
+- `--copy-from` does NOT change where source is located
+
+## Copy Source Flags (mutually exclusive)
+
+| Flag | Description |
+|------|-------------|
+| `--copy-from <name\|path>` | Copy skills from target name or directory path |
+| `--no-copy` | Start with empty source |
+
+## Target Flags (mutually exclusive)
+
+| Flag | Description |
+|------|-------------|
+| `--targets <list>` | Comma-separated targets: `"claude,cursor,codex"` |
+| `--all-targets` | Add all detected CLI targets |
+| `--no-targets` | Skip target setup |
+
+## Git Flags (mutually exclusive)
+
+| Flag | Description |
+|------|-------------|
+| `--git` | Initialize git in source (recommended) |
+| `--no-git` | Skip git initialization |
+
+## Discover Flags (for adding new agents to existing config)
+
+| Flag | Description |
+|------|-------------|
+| `--discover` | Detect and add new agents to existing config (interactive) |
+| `--select <list>` | Comma-separated agents to add (non-interactive, requires `--discover`) |
+
+## Other Flags
+
+| Flag | Description |
+|------|-------------|
+| `--source <path>` | Custom source directory (**only if user explicitly requests**) |
+| `--remote <url>` | Set git remote (implies `--git`) |
+| `--dry-run` | Preview without making changes |
+
+**AI Note:** Never use `--source` unless the user explicitly asks to change the source location.
+
+## Examples
+
+```bash
+# Fresh start with all targets and git
+skillshare init --no-copy --all-targets --git
+
+# Copy from Claude, specific targets
+skillshare init --copy-from claude --targets "claude,cursor" --git
+
+# Minimal setup
+skillshare init --no-copy --no-targets --no-git
+
+# Custom source with remote
+skillshare init --source ~/my-skills --remote git@github.com:user/skills.git
+
+# Add new agents to existing config (non-interactive)
+skillshare init --discover --select "windsurf,kilocode"
+
+# Add new agents (interactive)
+skillshare init --discover
