Review first review before installing

Open the source and read safety notes before installing.

Safety notes

  • Slack threads may contain customer excerpts; redact before delegating to Claude Code sessions with repository access.
  • Require human approval for write tools, deployments, and PR merges initiated from Slack delegations.
  • Do not post credentials, OAuth codes, or internal URLs with embedded tokens into Slack delegations.

Privacy notes

  • Slack message history and Claude Code session output may replicate across systems; align retention policies.
  • Delegated tasks can expose file paths and issue details in Slack replies visible to channel members.
  • Use private channels or DMs for sensitive repositories unless channel membership matches repository access.

Prerequisites

  • Claude Code Slack integration configured per official documentation for your workspace.
  • Named channels or threads for delegated work with linked repository and branch context.
  • Team policy for which tasks may be delegated (docs, tests, small fixes) versus forbidden (prod deploys, secret rotation).
  • Engineers available to approve tool actions that exceed auto-approved permissions.

Use this guide to delegate bounded engineering tasks from Slack to Claude Code with explicit repos, success criteria, and approval paths.

About this resource

TL;DR

Slack delegation works when tasks are bounded: name the repo, branch, success criteria, and approval path. Use the Claude Code Slack integration for handoffs, keep production-risk actions behind human approval, and post status updates back to the thread instead of silent background work.

Prerequisites & Requirements

  • {"task": "Slack integration live", "description": "Workspace setup matches official Slack documentation"}
  • {"task": "Delegation template published", "description": "Repo, branch, paths, tests, and reviewer are required fields"}
  • {"task": "Allowed task classes defined", "description": "Team policy lists permitted and forbidden delegations"}
  • {"task": "Approval coverage scheduled", "description": "Reviewers are available during delegated channel hours"}
  • {"task": "Status loop required", "description": "Completion summaries with PR links return to the Slack thread"}

Core Concepts Explained

Slack is the intake, not the source of truth

Threads initiate work; repositories, issues, and CI remain authoritative. Link them explicitly in every delegation.

Delegation needs contracts

A good delegation includes objective, allowed paths, tests to run, deadline, and who approves merges.

Permissions must match channel trust

Channels with broad membership should delegate read-only analysis; write access belongs in restricted channels with reviewers online.

Status loops prevent duplicate work

Configure replies or summaries back to Slack so teammates see progress and blockers.

Step-by-Step Workflow

  1. Configure Slack integration. Complete workspace setup per Claude Code Slack documentation.

  2. Define allowed task classes. Publish examples: triage logs, draft tests, summarize PRs—not production changes without review.

  3. Create delegation template. Include repo link, branch, paths, tests, and reviewer handle.

  4. Post delegation in scoped channel. Use threads per task to keep context isolated.

  5. Monitor Claude Code session. Watch for permission prompts requiring human approval in Slack or terminal.

  6. Require PR before merge. Even when Claude opens a PR, human review stays mandatory unless policy says otherwise.

  7. Post completion summary. Link PR, tests run, and known gaps back to Slack.

  8. Retrospect weekly. Collect misfires—wrong repo, over-broad edits—and tighten templates.

Delegation Template Fields

Field Purpose
Repository URL Removes ambiguity about target codebase
Branch Prevents work on stale default branch
Allowed paths Bounds diff scope
Tests to run Defines done criteria
Reviewer Names merge approval owner

Troubleshooting

Claude worked on the wrong repository

Add explicit repo URLs to the delegation template and ban ambiguous "fix the bug" requests without links.

Permission prompts stalled the task

Assign on-call reviewers for delegated channels during business hours.

Slack thread lacks final status

Make "post summary with PR link" part of the delegation checklist for humans and Claude.

Sensitive data appeared in channel replies

Move delegations to private channels and redact customer content at intake.

Duplicate Check

This guide complements channels-and-webhooks-into-running-claude-code-sessions.mdx by focusing on Slack-native engineering delegation rather than generic webhook bridging.
