Cove Ops

Operate the Cove platform — channel files, cove.md, webhooks, channels, messages, members, reactions, roles, and permissions.

Platform Concepts

Cove is a channel-based communication platform (similar to Discord). Agents connect as bots and interact through channels.

Core concepts:

cove.md — Every channel has a persistent context file called cove.md. It is automatically injected into the bot's context every turn. Bots can read and write it. Channel-level rules, conventions, and state belong here, not in personal memory. This is a platform-level guarantee.
Channel files — Each channel has its own file storage (text-based, max 100KB/file). cove.md is the convention file, but you can store other files too.
Cross-channel communication — Channels communicate via webhooks. It's one-way push only — no auto-return, to prevent echo loops. Each channel processes what it receives independently.
Channel as Service — Each channel has its own role (dev, product, review, etc.). The platform orchestrates everything. Different channels, different responsibilities.
Roles & Permissions — Discord-compatible RBAC. Guild has roles with permission bits. Members are assigned roles. Role hierarchy (position) determines what you can manage.

Tip: Record these platform concepts in your persistent config (e.g., TOOLS.md) so you naturally recall them on every startup.

Prerequisites

Config lives in ~/.openclaw/openclaw.json → channels.cove:

json

{
  "token": "BOT_TOKEN",
  "baseUrl": "https://staging.cove.kagura-agent.com",
  "guildId": "GUILD_ID"
}

Read config:

bash

COVE_BASE=$(jq -r '.channels.cove.baseUrl' ~/.openclaw/openclaw.json)
COVE_TOKEN=$(jq -r '.channels.cove.token' ~/.openclaw/openclaw.json)
COVE_GUILD=$(jq -r '.channels.cove.guildId' ~/.openclaw/openclaw.json)

All API calls need:

text

-H "Authorization: Bot $COVE_TOKEN"
-H "Content-Type: application/json"

API prefix: $COVE_BASE/api/v10/

Roles

Role Hierarchy

Roles have a position field that determines hierarchy:

position: 0 = @everyone (immutable, cannot be deleted)
Higher position = more power
You can only manage roles BELOW your highest role position
Only the guild owner is exempt from position checks
ADMINISTRATOR permission does NOT bypass position hierarchy

New roles are created at position 1 (just above @everyone); existing roles shift up.

Permission Bits

Common permission bits (BigInt string):

Permission	Bit	Value
ADMINISTRATOR	1 << 3	8
MANAGE_GUILD	1 << 5	32
MANAGE_ROLES	1 << 28	268435456
MANAGE_CHANNELS	1 << 4	16
VIEW_CHANNEL	1 << 10	1024
SEND_MESSAGES	1 << 11	2048
MANAGE_MESSAGES	1 << 13	8192

ADMINISTRATOR grants all permissions. Permissions are OR'd across all member roles.

List Roles

bash

curl -s "$COVE_BASE/api/v10/guilds/$COVE_GUILD/roles" \
  -H "Authorization: Bot $COVE_TOKEN"

Returns: [{id, name, position, permissions, color, hoist, managed, mentionable}, ...]

Create Role

bash

curl -s -X POST "$COVE_BASE/api/v10/guilds/$COVE_GUILD/roles" \
  -H "Authorization: Bot $COVE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "Moderator", "permissions": "268435456", "color": 3447003}'

Requires: MANAGE_ROLES. New role permissions must be a subset of caller's permissions. New role is created at position 1 (bottom, above @everyone).

Update Role

bash

curl -s -X PATCH "$COVE_BASE/api/v10/guilds/$COVE_GUILD/roles/ROLE_ID" \
  -H "Authorization: Bot $COVE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "New Name", "permissions": "268435456", "color": 15158332}'

Requires: MANAGE_ROLES + target role must be below caller's highest position.

Update Role Positions

bash

curl -s -X PATCH "$COVE_BASE/api/v10/guilds/$COVE_GUILD/roles" \
  -H "Authorization: Bot $COVE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '[{"id": "ROLE_ID", "position": 2}, {"id": "OTHER_ROLE_ID", "position": 1}]'

Requires: MANAGE_ROLES. Cannot move roles at or above caller's highest position.

Delete Role

bash

curl -s -X DELETE "$COVE_BASE/api/v10/guilds/$COVE_GUILD/roles/ROLE_ID" \
  -H "Authorization: Bot $COVE_TOKEN"

Requires: MANAGE_ROLES + target role below caller's position. Cannot delete @everyone or managed roles.

Assign Role to Member

bash

curl -s -X PUT "$COVE_BASE/api/v10/guilds/$COVE_GUILD/members/USER_ID/roles/ROLE_ID" \
  -H "Authorization: Bot $COVE_TOKEN"

Requires: MANAGE_ROLES + target role below caller's position.

Remove Role from Member

bash

curl -s -X DELETE "$COVE_BASE/api/v10/guilds/$COVE_GUILD/members/USER_ID/roles/ROLE_ID" \
  -H "Authorization: Bot $COVE_TOKEN"

Requires: MANAGE_ROLES + target role below caller's position. Cannot remove managed roles.

Channel Files

Every channel has an independent file space. Files are text-based, max 100KB.

cove.md Convention

cove.md is the special convention file per channel:

Auto-injected: plugin dispatch reads it and injects into bot context every turn
Bot-readable and writable: bots can GET/PUT to evolve channel rules
Pinned first: always sorted to the top of file listings

List Files (metadata only)

bash

curl -s "$COVE_BASE/api/v10/channels/CHANNEL_ID/files" \
  -H "Authorization: Bot $COVE_TOKEN"

Read File

bash

curl -s "$COVE_BASE/api/v10/channels/CHANNEL_ID/files/FILENAME" \
  -H "Authorization: Bot $COVE_TOKEN"

Create / Update File

bash

curl -s -X PUT "$COVE_BASE/api/v10/channels/CHANNEL_ID/files/FILENAME" \
  -H "Authorization: Bot $COVE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"content": "file content here", "content_type": "text/plain"}'

Filename rules: /^[a-zA-Z0-9][a-zA-Z0-9._-]{0,254}$/

Delete File

bash

curl -s -X DELETE "$COVE_BASE/api/v10/channels/CHANNEL_ID/files/FILENAME" \
  -H "Authorization: Bot $COVE_TOKEN"

Update cove.md (common pattern)

bash

curl -s -X PUT "$COVE_BASE/api/v10/channels/CHANNEL_ID/files/cove.md" \
  -H "Authorization: Bot $COVE_TOKEN" \
  -H "Content-Type: application/json" \
  -d "$(jq -nc --arg content '# channel-name

Channel rules and context here.
- Rule 1
- Rule 2' '{content: $content}')"

Use jq -nc to safely construct JSON with multiline content.

Cross-Channel Messaging (Webhooks)

Send messages between channels via webhooks. Webhook messages appear as a different identity, so the bot in the target channel can receive and process them.

Key Principle

One-way push only. Each channel processes what it receives. Results do NOT auto-return unless explicitly requested. This prevents echo loops.

Helper Script (recommended)

bash

node ~/.openclaw/workspace-ruantang/cove/skills/cove-webhook/scripts/cove-webhook-send.mjs \
  --to TARGET_CHANNEL_NAME \
  --from SOURCE_CHANNEL_NAME \
  --message "Your message here"

The script auto-creates and caches webhooks. No manual webhook management needed.

Manual: Create Webhook

bash

curl -s -X POST "$COVE_BASE/api/v10/channels/CHANNEL_ID/webhooks" \
  -H "Authorization: Bot $COVE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name": "cross-channel-hook"}'

Manual: Execute Webhook (send message)

bash

# Send to channel (returns message body with ?wait=true)
curl -s -X POST "$COVE_BASE/api/v10/webhooks/WEBHOOK_ID/WEBHOOK_TOKEN?wait=true" \
  -H "Content-Type: application/json" \
  -d '{"content": "Message text", "username": "From #source-channel"}'

# Send to a thread within the webhook's channel
curl -s -X POST "$COVE_BASE/api/v10/webhooks/WEBHOOK_ID/WEBHOOK_TOKEN?wait=true&thread_id=THREAD_ID" \
  -H "Content-Type: application/json" \
  -d '{"content": "Message in thread", "username": "From #source-channel"}'

Query params:

?wait=true — return created message (default: 204 No Content)
?thread_id=ID — post to a thread instead of the channel

No auth header needed — the token in the URL is the auth.

Bot Channel Permissions

Control which channels a bot can access via permission overwrites:

# Grant VIEW_CHANNEL (bit 10 = 1024)
curl -s -X PUT "$COVE_BASE/api/v10/channels/CHANNEL_ID/permissions/BOT_USER_ID" \
  -H "Authorization: Bot $COVE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"type": 1, "allow": "1024", "deny": "0"}'

# Deny VIEW_CHANNEL
curl -s -X PUT "$COVE_BASE/api/v10/channels/CHANNEL_ID/permissions/BOT_USER_ID" \
  -H "Authorization: Bot $COVE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"type": 1, "allow": "0", "deny": "1024"}'

# Remove overwrite
curl -s -X DELETE "$COVE_BASE/api/v10/channels/CHANNEL_ID/permissions/BOT_USER_ID" \
  -H "Authorization: Bot $COVE_TOKEN"

Reactions

Add Reaction

bash

curl -s -X PUT "$COVE_BASE/api/v10/channels/CHANNEL_ID/messages/MSG_ID/reactions/EMOJI/@me" \
  -H "Authorization: Bot $COVE_TOKEN"

EMOJI is URL-encoded (e.g. %F0%9F%91%8D for 👍).

Remove Reaction

curl -s -X DELETE "$COVE_BASE/api/v10/channels/CHANNEL_ID/messages/MSG_ID/reactions/EMOJI/@me" \
  -H "Authorization: Bot $COVE_TOKEN"

Get Reactions

bash

curl -s "$COVE_BASE/api/v10/channels/CHANNEL_ID/messages/MSG_ID/reactions/EMOJI" \
  -H "Authorization: Bot $COVE_TOKEN"

Local Plugin Deployment

When plugin code (packages/plugin) changes, manually build + deploy:

bash

# 1. Build
cd ~/cove/packages/plugin && pnpm run build

# 2. Backup + replace
cp ~/.openclaw/extensions/cove/dist/index.js ~/.openclaw/extensions/cove/dist/index.js.bak
cp dist/index.js ~/.openclaw/extensions/cove/dist/index.js

# 3. Restart gateway
openclaw gateway restart

Staging CI only updates the Azure Cove server, not the local OpenClaw plugin.

Rules & Gotchas

Use jq -nc for JSON construction — shell string interpolation in JSON is error-prone
Webhook messages don't need auth header — token is in the URL
Cross-channel: no auto-return — results must be explicitly sent back via webhook
cove.md is auto-injected — bots see it every turn without manually reading
cove.md max 8KB for injection — larger files are stored but not injected into context
File storage max 100KB — per file limit
Filename regex — must match /^[a-zA-Z0-9][a-zA-Z0-9._-]{0,254}$/
Bot permissions — bots need VIEW_CHANNEL permission overwrite to access channel files/messages
WS events — file changes broadcast CHANNEL_FILE_CREATE/UPDATE/DELETE via WebSocket
Plugin caches cove.md — 60s TTL, invalidated on WS file events; changes may take up to 60s to take effect
Role hierarchy is king — even with ADMINISTRATOR, you cannot manage roles above your position. Only guild owner is exempt.
New role permissions must be subset — cannot create a role with permissions you don't have yourself
Managed roles — bot-linked roles cannot be manually assigned/removed/deleted
