# Nextcloud Integration - Progress Report
|
||||
|
||||
**Date:** 2026-02-11
|
||||
**Server:** https://teamworkapps.com (Nextcloud 25.0.13)
|
||||
**User:** wltbagent@shortcutsolutions.net
|
||||
|
||||
---
|
||||
|
||||
## ✅ Completed
|
||||
|
||||
### 1. Nextcloud Files Client (WebDAV)
|
||||
**Location:** `projects/nextcloud-integration/tools/go/nextcloud-client/`
|
||||
**Installed:** `~/bin/nextcloud-client`
|
||||
|
||||
**Status:** ✅ Working
|
||||
|
||||
**Features:**
|
||||
- `list` - Browse files and folders with metadata (size, dates, ETags)
|
||||
- `upload` - Upload files to Nextcloud
|
||||
- `download` - Download files from Nextcloud
|
||||
- `mkdir` - Create directories
|
||||
- `delete` - Remove files/folders
|
||||
- `info` - Get detailed file metadata
|
||||
- `move` - Move/rename files and folders
|
||||
- `copy` - Copy files and folders
|
||||
|
||||
**Recent Fix (2026-02-11):**
|
||||
Fixed WebDAV XML metadata parsing issue:
|
||||
- **Problem:** Nextcloud returns multiple `<propstat>` elements (200 OK for valid properties, 404 for missing ones like folders without contentlength/contenttype)
|
||||
- **Solution:** Added `PropStat` struct to handle multiple propstat elements, merged props from successful (200 OK) responses
|
||||
- **Result:** File sizes, dates, ETags, and content types now display correctly
|
||||
|
||||
**Test Results:**
|
||||
```
|
||||
✅ List root directory - shows 7 items with correct sizes
|
||||
✅ Upload test file - success
|
||||
✅ Download test file - content verified
|
||||
✅ Create test folder - success
|
||||
✅ Get file info - shows full metadata (size: 13.7MB, modified date, ETag, MIME type)
|
||||
✅ Delete test items - cleanup successful
|
||||
```
|
||||
|
||||
### 2. Nextcloud Contacts Client (CardDAV)
|
||||
**Location:** `projects/nextcloud-integration/tools/go/nextcloud-contacts/`
|
||||
**Installed:** `~/bin/nextcloud-contacts`
|
||||
|
||||
**Status:** ✅ Working
|
||||
|
||||
**Features:**
|
||||
- `list-books` - List all address books
|
||||
- `list-contacts` - List contacts in a specific address book
|
||||
- `get-contact` - Retrieve a specific contact vCard
|
||||
- `create-contact` - Create a new contact (with name, email, phone, or import from .vcf file)
|
||||
- `delete-contact` - Delete a contact
|
||||
|
||||
**Test Results:**
|
||||
```
|
||||
✅ List address books - shows 2 books (Contacts, Recently contacted)
|
||||
✅ List contacts - correctly reports empty address book
|
||||
✅ Create contact - successfully created test contact with name, email, phone
|
||||
✅ Delete contact - successfully deleted test contact
|
||||
✅ CardDAV endpoints accessible at /remote.php/dav/addressbooks/users/{username}/
|
||||
```
|
||||
|
||||
### 3. Nextcloud Calendar Client (CalDAV)
|
||||
**Location:** `projects/nextcloud-integration/tools/go/nextcloud-calendar/`
|
||||
**Installed:** `~/bin/nextcloud-calendar`
|
||||
|
||||
**Status:** ✅ Working
|
||||
|
||||
**Features:**
|
||||
- `list-calendars` - List all calendars
|
||||

|
||||
- `get-event` - Retrieve a specific event (iCalendar format)
|
||||
- `create-event` - Create a new event (with summary, start/end times, or import from .ics file)
|
||||
- `delete-event` - Delete an event
|
||||
|
||||
**URL Pattern:** `/remote.php/dav/calendars/{username}/` (different from CardDAV)
|
||||
|
||||
**Test Results:**
|
||||
```
|
||||
✅ List calendars - shows "Personal" calendar
|
||||
✅ List events - correctly reports empty calendar
|
||||
✅ Create event - successfully created test event with summary and times
|
||||
✅ Delete event - successfully deleted test event
|
||||
✅ CalDAV endpoints accessible at /remote.php/dav/calendars/{username}/
|
||||
```
|
||||
|
||||

|
||||
|
||||
## ❌ Not Available on Server
|
||||
|
||||
### 1. Calendar (CalDAV)
|
||||
**Status:** ❌ App not installed
|
||||
**Test:** `GET /remote.php/dav/calendars/users/{username}/`
|
||||
**Result:** 404 Not Found - "Principal with name users not found"
|
||||
|
||||
### 2. Notes (REST API)

|
||||
|
||||

|
||||
|
||||
## 📋 Current Server Capabilities
|
||||
|
||||
Based on testing, this Nextcloud server has:
|
||||
- ✅ Files app (WebDAV)
|
||||
- ✅ Contacts app (CardDAV)
|
||||
- ✅ Calendar app (CalDAV)
|
||||
- ✅ User management
|
||||
- ✅ Activity feed
|
||||
- ✅ Circles support
|
||||
- ❌ Notes app (REST API unresponsive, may not be installed)
|
||||
- ❌ Deck app
|
||||
- ❌ Talk app
|
||||
- ❌ Bookmarks app
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Next Steps
|
||||
|
||||
### Option 1: Continue with Available Apps
|
||||
Implement advanced features for working apps:
|
||||
1. **Contacts** - Add create, update, delete operations
|
||||
2. **Files** - Add share link generation, versioning support
|
||||
|
||||
### Option 2: Install Missing Apps
|
||||
Ask server admin to install:
|
||||
- Calendar app (for CalDAV support)
|
||||
- Notes app (for REST API notes)
|
||||
- Deck app (for Kanban boards)
|
||||
|
||||
### Option 3: Implement REST Skills for Documentation
|
||||
Create skills for apps even if not installed (for future use):
|
||||
1. **Calendar Skill** - Document CalDAV implementation (ready when app is installed)
|
||||
2. **Notes Skill** - Document REST API implementation (ready when app is installed)
|
||||
3. **Deck Skill** - Document REST API implementation (ready when app is installed)

|
||||
|
||||
## ✅ Skill Wrappers Created
|
||||
|
||||
### OpenClaw Skills
|
||||
|
||||
**Decision:** CLI tools + thin skill wrappers
|
||||
- ✅ Reduces token usage (binary handles logic)
|
||||
- ✅ More accurate (compiled Go code)
|
||||
- ✅ Reusable (tools work outside OpenClaw)
|
||||
- ✅ Testable (easy to verify independently)
|
||||
|
||||
**Skills Created:**
|
||||
|
||||
| Skill | Location | Wraps | Features |
|
||||
|-------|----------|--------|----------|
|
||||
| nextcloud-files | skills/nextcloud-files/SKILL.md | ~/bin/nextcloud-client | list, upload, download, mkdir, delete, move, copy, info |
|
||||
| nextcloud-contacts | skills/nextcloud-contacts/SKILL.md | ~/bin/nextcloud-contacts | list-books, list-contacts, get-contact, create-contact, delete-contact |
|
||||
| nextcloud-calendar | skills/nextcloud-calendar/SKILL.md | ~/bin/nextcloud-calendar | list-calendars, list-events, get-event, create-event, delete-event |
|
||||
|
||||
**Skill Structure:**
|
||||
- Environment variable configuration
|
||||
- Tool reference with examples
|
||||
- Use cases and workflows
|
||||
- Error handling guide
|

|

|
||||
## ✅ Build-Time Credentials Implemented (Final Milestone)
|
||||
|
||||
### Build Script Created
|
||||
|
||||
**Location:** `projects/nextcloud-integration/build.sh`
|
||||
|
||||
**Features:**
|
||||
- One-command build for all three tools
|
||||
- Accepts server URL, username, and token as arguments
|
||||
- Embeds credentials via Go ldflags
|
||||
- Verifies successful builds
|
||||
- Installs binaries to ~/bin/
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
./build.sh <server-url> <username> <token>
|
||||
```
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
./build.sh https://teamworkapps.com wltbagent@shortcutsolutions.net 1b8a28ca2fc26820fee3f9a8524c351b
|
||||
```
|
||||
|
||||
### Configuration Priority
|
||||
|
||||
All three tools now support:
|
||||
|
||||
1. **Build-time ldflags** (highest priority)
|
||||
- Set at compile time
|
||||
- Embedded in binary
|
||||
- No runtime configuration needed
|
||||
|
||||
2. **Environment variables** (fallback)
|
||||
- NEXTCLOUD_URL
|
||||
- NEXTCLOUD_USER
|
||||
- NEXTCLOUD_TOKEN
|
||||
|
||||
3. **Command-line flags** (lowest priority)
|
||||
- --url, --user, --token
|
||||
- Override both ldflags and env vars
|
||||
|
||||
### Benefits
|
||||
|
||||
- ✅ No environment variables needed at runtime
|
||||
- ✅ Credentials embedded at build time (more secure)
|
||||
- ✅ Simplified command invocation
|
||||
- ✅ One-command rebuild for all tools
|
||||
|
||||
### Security Note
|
||||
|
||||
**Important:** Binaries built with ldflags contain credentials in clear text. Do not distribute built binaries outside your trusted environment.
|
||||
|
||||
### Updated Skills
|
||||
|
||||
All three SKILL.md files updated with:
|
||||
- Build-time credential instructions
|
||||
- Build script usage
|
||||
- Security warnings
|
||||
- Configuration priority explanation
|
||||
|
||||

||||
|
||||
**Contents:**

||||
- Quick start guide
|
||||
