+description: Validate Claude Code marketplace or plugin by discovering manifest files
+---
+
+Intelligently validate Claude Code manifests by discovering them in common locations.
+
+**Discovery Logic:**
+
+1. **Check for marketplace at repository root**: `../../.claude-plugin/marketplace.json` (relative to current directory)
+2. **Check for local plugin**: `.claude-plugin/plugin.json` in current directory
+3. **Check for marketplace in current directory**: `.claude-plugin/marketplace.json`
+4. **If manifest found**: Validate it
+5. **If none found**: Report where manifests were searched
+
+**Usage:**
+
+Simply run the command - it will discover and validate manifests automatically:
+```bash
+/claude-plugin-validate
+```
+
+**Implementation:**
+
+```bash
+# Function to find and validate manifests
+validate_discovered() {
+    local repo_root
+    local current_dir="$(pwd)"
+
+    # Try to find git root
+    repo_root=$(git rev-parse --show-toplevel 2>/dev/null || echo "$current_dir")
+
+    # 1. Check for marketplace at repo root
+    if [ -f "$repo_root/.claude-plugin/marketplace.json" ]; then
+        echo "Found marketplace at repository root:"
+        claude plugin validate "$repo_root/.claude-plugin/marketplace.json"
+        return $?
+    fi
+
+    # 2. Check for local plugin
+    if [ -f "$current_dir/.claude-plugin/plugin.json" ]; then
+        echo "Found plugin in current directory:"
+        claude plugin validate "$current_dir"
+        return $?
+    fi
+
+    # 3. Check for local marketplace
+    if [ -f "$current_dir/.claude-plugin/marketplace.json" ]; then
+        echo "Found marketplace in current directory:"
+        claude plugin validate "$current_dir/.claude-plugin/marketplace.json"
+        return $?
+    fi
+
+    # 4. Nothing found
+    echo "No manifest found. Searched:"
+    echo "  - $repo_root/.claude-plugin/marketplace.json (repository marketplace)"
+    echo "  - $current_dir/.claude-plugin/plugin.json (local plugin)"
+    echo "  - $current_dir/.claude-plugin/marketplace.json (local marketplace)"
+    return 1
+}
+
+validate_discovered
+```
+
+**Example Output:**
+
+When marketplace found at root:
+```
+Found marketplace at repository root:
+Validating marketplace manifest: /path/to/repo/.claude-plugin/marketplace.json
+✔ Validation passed
+```
+
+When plugin found locally:
+```
+Found plugin in current directory:
+Validating plugin manifest: /path/to/plugin/.claude-plugin/plugin.json
+✔ Validation passed
+```
+
+When nothing found:
+```
+No manifest found. Searched:
+  - /path/to/repo/.claude-plugin/marketplace.json (repository marketplace)
+  - /current/dir/.claude-plugin/plugin.json (local plugin)
+  - /current/dir/.claude-plugin/marketplace.json (local marketplace)
+```
+
+**Use Cases:**
+
+- Quick validation from anywhere in repository
+- CI/CD validation scripts
+- Pre-commit hooks
+- Development workflow integration
+
+**Notes:**
+
+- Searches in priority order (marketplace root → local plugin → local marketplace)
+- Uses git to find repository root if available
+- Falls back to current directory if not in git repository
+- Returns appropriate exit codes for scripting
