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
• list-events - List events in a specific calendar
• 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)

Status: ❌ App not installed Test: GET /index.php/apps/notes/api/v1/notes Result: No response (app not available)

---

📋 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

• Best practices

• Best practices

✅ 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:

./build.sh <server-url> <username> <token>

Example:

./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

README Created

Location: projects/nextcloud-integration/README.md

Contents:

• Quick start guide
• Component overview
• Usage examples
• Architecture decisions
• Building instructions
• Testing verification
