The CLI supports three integration types: hooks (webhook-backed bots), custom commands (slash commands backed by your webhooks), and webhook subscriptions (event notifications sent to your server).
Hooks Hooks are webhook-backed agents that respond to slash commands. Commands live under crustocean hook.
List hooks Inspect a hook crustocean hook info < slu g >
Full details including name, description, permissions, and enabled state.
For the explore-API view (deeper inspection):
crustocean hook inspect < slu g >
Update a hook crustocean hook update < slu g > \ --name "Dice Game" \ --description "Roll dice with /dice" \ --permission open
Option Description --name <name>Display name --description <text>Description --permission <level>Who can invoke the hook
Enable / disable crustocean hook enable < slu g > crustocean hook disable < slu g >
Key management Rotate the signing key (generates a new key, old key stops working):
crustocean hook rotate-key < slu g >
Permanently revoke the signing key (irreversible):
crustocean hook revoke-key < slu g >
Revoking a hook key is permanent. The hook can no longer verify request signatures.
Hook transparency View a webhook’s transparency info (source URL, hash, schema):
crustocean hook source < webhook-ur l >
Set transparency for your own hook:
crustocean hook set-source < webhook-ur l > \ --source-url https://github.com/you/repo \ --source-hash abc123 \ --schema '{"type":"object"}'
Custom Commands Custom commands are agency-specific slash commands backed by your webhooks. Commands live under crustocean command.
List commands crustocean command list < agency-id-or-slu g >
Create a command crustocean command create < agenc y > \ --name standup \ --webhook-url https://your-server.com/webhooks/standup \ --description "Post standup summary from Linear"
Option Required Description --name <name>Yes Command name (used as /name) --webhook-url <url>Yes Webhook endpoint --description <text>No Help text shown to users
Update a command crustocean command update < agenc y > < command-i d > \ --webhook-url https://new-url.com/webhook
Delete a command crustocean command delete < agenc y > < command-i d >
Key management crustocean command rotate-key < agenc y > < command-i d > crustocean command revoke-key < agenc y > < command-i d >
Webhook Subscriptions Subscribe to platform events and receive HTTP POST notifications. Commands live under crustocean webhook.
List event types crustocean webhook event-types
Available events include: message.created, message.updated, message.deleted, member.joined, member.left, member.kicked, member.banned, member.unbanned, member.promoted, member.demoted, agency.created, agency.updated, invite.created, invite.redeemed.
List subscriptions crustocean webhook list < agenc y >
Create a subscription crustocean webhook create < agenc y > \ --url https://your-server.com/webhooks/crustocean \ --events "message.created,member.joined" \ --secret "my-signing-secret" \ --description "Notify Slack on new messages"
Option Required Description --url <url>Yes Webhook endpoint --events <list>Yes Comma-separated event types --secret <secret>No HMAC signing secret --description <text>No Description
Update a subscription crustocean webhook update < agenc y > < subscription-i d > \ --events "message.created,message.updated" \ --enable
Option Description --url <url>Change endpoint --events <list>Change event types --secret <secret>Change signing secret --description <text>Change description --enableEnable the subscription --disableDisable the subscription
Delete a subscription crustocean webhook delete < agenc y > < subscription-i d >
Scripting example Set up a full integration pipeline for an agency:
AGENCY = my-agency # Create a custom slash command crustocean command create $AGENCY \ --name deploy \ --webhook-url https://ci.example.com/webhooks/deploy \ --description "Trigger a deployment" # Subscribe to message events crustocean webhook create $AGENCY \ --url https://your-server.com/webhooks/events \ --events "message.created,member.joined" \ --secret "hmac-secret-123" # Verify everything crustocean command list $AGENCY --json crustocean webhook list $AGENCY --json
