Matrix Server Management

Overview

This skill allows you to manage the Tuwunel Matrix Homeserver. Tuwunel is a conduwuit fork running at http://127.0.0.1:6167. Access the server directly (not through the Higress gateway).

Environment Variables

These environment variables are pre-configured in the Manager container:

# Core configuration (set by hiclaw-install.sh)
HICLAW_MATRIX_DOMAIN       # Matrix server domain (e.g., matrix-local.hiclaw.io:8080)
HICLAW_ADMIN_USER          # Admin username
HICLAW_REGISTRATION_TOKEN  # Token for registering new Matrix users
HICLAW_MANAGER_PASSWORD    # Manager's Matrix password (for login)

No need to set defaults - these are always available in the container environment.

User Registration

Tuwunel uses single-step registration with a registration token (no UIAA flow).

Register a New User

curl -X POST http://127.0.0.1:6167/_matrix/client/v3/register \
  -H 'Content-Type: application/json' \
  -d '{
    "username": "<USERNAME>",
    "password": "<PASSWORD>",
    "auth": {
      "type": "m.login.registration_token",
      "token": "'"${HICLAW_REGISTRATION_TOKEN}"'"
    }
  }'

Response includes user_id and access_token.

Login (Get Access Token)

curl -X POST http://127.0.0.1:6167/_matrix/client/v3/login \
  -H 'Content-Type: application/json' \
  -d '{
    "type": "m.login.password",
    "identifier": {"type": "m.id.user", "user": "<USERNAME>"},
    "password": "<PASSWORD>"
  }'

Response: {"access_token": "...", "user_id": "@:", ...}

Room Management

Create a Room (3-party: Human + Manager + Worker)

When creating a Worker, always create a Room with the human admin, Manager, and Worker. Use trusted_private_chat preset so all invited members are auto-joined (no invite acceptance needed), and override power levels so Admin + Manager get 100 (admin) while Workers get 0 (regular user):

MANAGER_TOKEN="<manager_access_token>"
curl -X POST http://127.0.0.1:6167/_matrix/client/v3/createRoom \
  -H "Authorization: Bearer ${MANAGER_TOKEN}" \
  -H 'Content-Type: application/json' \
  -d '{
    "name": "Worker: <WORKER_NAME>",
    "topic": "Communication channel for <WORKER_NAME>",
    "invite": [
      "@'"${HICLAW_ADMIN_USER}"':'"${HICLAW_MATRIX_DOMAIN}"'",
      "@<WORKER_NAME>:'"${HICLAW_MATRIX_DOMAIN}"'"
    ],
    "preset": "trusted_private_chat",
    "power_level_content_override": {
      "users": {
        "@manager:'"${HICLAW_MATRIX_DOMAIN}"'": 100,
        "@'"${HICLAW_ADMIN_USER}"':'"${HICLAW_MATRIX_DOMAIN}"'": 100,
        "@<WORKER_NAME>:'"${HICLAW_MATRIX_DOMAIN}"'": 0
      }
    }
  }'

Response: {"room_id": "!:"}

Power levels: trusted_private_chat auto-joins all invited members (no invite acceptance needed). power_level_content_override ensures Admin (100) and Manager (100) have admin rights while Workers are explicitly set to 0 (regular user).

Send a Message in a Room

Simple message (no mention):

curl -X PUT "http://127.0.0.1:6167/_matrix/client/v3/rooms/<ROOM_ID>/send/m.room.message/$(date +%s)" \
  -H "Authorization: Bearer ${MANAGER_TOKEN}" \
  -H 'Content-Type: application/json' \
  -d '{
    "msgtype": "m.text",
    "body": "Hello, this is a general announcement..."
  }'

Send a Message with @Mention (Critical for Workers)

IMPORTANT: When sending messages to Workers in group rooms, you MUST include the m.mentions field for them to receive the message. Workers have requireMention: true enabled, meaning they only process messages that properly @mention them.

# Mention a single user
curl -X PUT "http://127.0.0.1:6167/_matrix/client/v3/rooms/<ROOM_ID>/send/m.room.message/$(date +%s)" \
  -H "Authorization: Bearer ${MANAGER_TOKEN}" \
  -H 'Content-Type: application/json' \
  -d '{
    "msgtype": "m.text",
    "body": "@<WORKER_NAME>:'"${HICLAW_MATRIX_DOMAIN}"' Your task assignment: ...",
    "m.mentions": {
      "user_ids": ["@<WORKER_NAME>:'"${HICLAW_MATRIX_DOMAIN}"'"]
    }
  }'

# Mention multiple users
curl -X PUT "http://127.0.0.1:6167/_matrix/client/v3/rooms/<ROOM_ID>/send/m.room.message/$(date +%s)" \
  -H "Authorization: Bearer ${MANAGER_TOKEN}" \
  -H 'Content-Type: application/json' \
  -d '{
    "msgtype": "m.text",
    "body": "@alice:'"${HICLAW_MATRIX_DOMAIN}"' and @bob:'"${HICLAW_MATRIX_DOMAIN}"' please coordinate on this task...",
    "m.mentions": {
      "user_ids": [
        "@alice:'"${HICLAW_MATRIX_DOMAIN}"'",
        "@bob:'"${HICLAW_MATRIX_DOMAIN}"'"
      ]
    }
  }'

Rules for @mentions:

• The user_ids array in m.mentions MUST contain the full Matrix user ID (e.g., @alice:matrix-local.hiclaw.io:8080)
• The user ID in the body text and in m.mentions.user_ids must match exactly
• Without m.mentions, Workers will receive the message but will NOT process it (it will be ignored)
• This follows Matrix MSC3952 (Intentional Mentions) specification

Upload a File (Media Upload)

Use this to send files to the admin — task output artifacts, generated reports, config exports, log files, etc.

curl -X POST "http://127.0.0.1:6167/_matrix/media/v3/upload?filename=<FILENAME>" \
  -H "Authorization: Bearer ${MANAGER_TOKEN}" \
  -H "Content-Type: application/octet-stream" \
  --data-binary @/path/to/file

Response: {"content_uri": "mxc:///"}

After uploading, send the mxc:// URI to the admin as a Matrix message using the m.file (or m.image / m.text) msgtype:

curl -X PUT "http://127.0.0.1:6167/_matrix/client/v3/rooms/<ROOM_ID>/send/m.room.message/$(date +%s)" \
  -H "Authorization: Bearer ${MANAGER_TOKEN}" \
  -H 'Content-Type: application/json' \
  -d '{
    "msgtype": "m.file",
    "body": "<FILENAME>",
    "url": "mxc://<SERVER>/<MEDIA_ID>"
  }'

Then reply in the conversation with:

MEDIA: mxc://<SERVER>/<MEDIA_ID>

Notes:

• Use Content-Type: text/plain for plain text files, application/octet-stream as a safe fallback for any binary
• The mxc:// URI is permanent and accessible to all room members via the Matrix client (Element Web)

List Joined Rooms

curl -s http://127.0.0.1:6167/_matrix/client/v3/joined_rooms \
  -H "Authorization: Bearer ${MANAGER_TOKEN}" | jq

Get Room Messages

curl -s "http://127.0.0.1:6167/_matrix/client/v3/rooms/<ROOM_ID>/messages?dir=b&limit=20" \
  -H "Authorization: Bearer ${MANAGER_TOKEN}" | jq

Important Notes

• Environment prefix: Tuwunel uses CONDUWUIT_ environment variable prefix (NOT TUWUNEL_)
• Server name: Set in CONDUWUIT_SERVER_NAME, usually ${HICLAW_MATRIX_DOMAIN}
• User ID format: @:${HICLAW_MATRIX_DOMAIN}
• Registration token: Stored in HICLAW_REGISTRATION_TOKEN env var
• Direct access: Use http://127.0.0.1:6167 for server management (not through Higress Gateway port 8080)
