configure

configure is a skill for Claude Code from jeremylongshore/claude-code-slack-channel. It costs 55 tokens per session (1,870 once invoked), scanned B, original, Apache-2.0.

A setup command for connecting a coding agent to Slack, a team messaging service, using two Slack app tokens.

In plain words
What is it for?
Use it to configure or rotate the Slack bot token and app-level token needed by the Slack channel plugin.
Why use it?
It keeps token validation and storage in one place, prevents tokens from being printed, and saves them with owner-only file permissions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

configure scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/slack-channel:configure

Overview

Configure the Slack channel with its bot and app-level tokens. This is the only token-writing path: validate prefixes, write .env with owner-only permissions, never echo secrets, and return control to the install walkthrough.

Prerequisites

  • A Slack app already created (via /slack-channel:install Step 1 or manually at api.slack.com/apps) with:
    • the Bot User OAuth Token (xoxb-...) from OAuth & Permissions, and
    • the App-Level Token (xapp-..., scope connections:write) from Socket Mode settings.
  • A writable home directory — state lives at ~/.claude/channels/slack/.

Usage

Pass both tokens as arguments, bot token first. Obtain them directly from the Slack app dashboard and avoid shell history or shared transcripts:

/slack-channel:configure <xoxb-bot-token> <xapp-app-token>

Authentication

  • The xoxb- Bot User OAuth Token represents the installed bot and authorizes Web API calls within its granted bot scopes.
  • The xapp- app-level token represents the Slack app and requires connections:write to open the Socket Mode WebSocket.
  • Prefix checks establish token type, not validity. install doctor verifies liveness against Slack without printing the credential.
  • Store tokens only in ~/.claude/channels/slack/.env; never commit them or include them in output, logs, screenshots, or issue reports.

Read references/official-auth.md when creating, rotating, revoking, or diagnosing either token type.

Instructions

  1. Parse the two arguments from $ARGUMENTS:

    • First token must start with xoxb- (Bot User OAuth Token)
    • Second token must start with xapp- (App-Level Token)
  2. If either token is missing or has the wrong prefix, show this error and stop:

    Error: Two tokens required.
      - Bot token (starts with xoxb-) from OAuth & Permissions
      - App token (starts with xapp-) from Socket Mode settings
    
    Usage: /slack-channel:configure xoxb-... xapp-...

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

configure is a skill published in the GitHub repository jeremylongshore/claude-code-slack-channel (39 stars, last pushed yesterday), licensed Apache-2.0. It adds 55 tokens to every session and 1,870 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
