Slack

Bucky listens for @bucky mentions in Slack channels and threads. He can answer engineering questions, explore code, pull observability data, and kick off Claude sessions to get work done.

How to use

Mention @bucky in any channel where the Slack app is installed:

@bucky what service handles payment processing?

@bucky there's a spike in 500 errors on the checkout service, can you investigate?

@bucky implement a retry mechanism for the payment webhook handler in fetch-rewards/checkout-service

What Bucky can do in Slack

Answer questions — searches code via Sourcegraph, pulls Grafana dashboards, checks Rollbar errors
Investigate issues — combines observability data with code context to diagnose problems
Create Jira tickets — for implementation work that needs backlog tracking
Create GitHub issues — with or without a linked Jira ticket
Dispatch Claude sessions — kicks off Claude sessions on GitHub issues
Post interactive messages — buttons, selects, and date pickers via Block Kit

Thread continuity

Bucky maintains conversation context within a Slack thread. Follow-up messages in the same thread are routed to the same ADK session, so you can have multi-turn conversations:

User: @bucky what does the payment webhook handler do?
Bucky: [explains the handler]
User: can you add retry logic to it?
Bucky: [creates a Jira ticket and GitHub issue, dispatches a plan session]

Interactive messages

Bucky can post Block Kit interactive messages with buttons, select menus, and date pickers. When you interact with these (click a button, choose an option), your selection is routed back to the agent session as a follow-up message.

Multimodal support

Bucky can process images shared in Slack threads. Images are:

Downloaded via the Slack bot token
Uploaded to S3 for permanent storage
Sent to Claude as inline image data for visual understanding
Included as URLs in any GitHub issues or sessions created from the conversation

Supported formats: JPEG, PNG, GIF, WebP.
