ask-slack

Slack service context for AI agents in the ask-rb ecosystem. It provides an authenticated Slack Web API client built on slack-ruby-client, metadata constants for system prompts, and a structured error guide for common Slack API issues.

gem "ask-slack"

require "ask-slack"

client = Ask::Slack.client
client.chat_postMessage(channel: "#general", text: "Hello from ask-rb!")
client.conversations_list
client.users_list

Ask::Slack.client resolves a token via Ask::Auth.resolve(:slack_token). Set your Slack Bot User OAuth Token in the environment:

export SLACK_TOKEN=xoxb-your-bot-token-here

Or add it to ~/.ask/credentials.yml:

slack_token: xoxb-your-bot-token-here

Credentials can also come from Rails credentials, a database, or an OAuth provider, depending on your ask-auth configuration. Create a Slack app at api.slack.com/apps to get a bot token.

• Ask::Slack.client - an authenticated Slack::Web::Client. It is wrapped in a proxy that converts auth errors (NotAuthed, InvalidAuth, and related) into Ask::Auth::InvalidCredential and retries transient network failures with exponential backoff.
• Ask::Slack::Errors - structured error knowledge for agents: guidance by error string, HTTP status code descriptions, and exception class mapping.
• Ask::Slack::DESCRIPTION, DOCS_URL, AUTH_NAME, GEM_NAME, GEM_VERSION, and QUICK_START - metadata constants for system prompts.

Use conversations_list, not channels_list. channels_list was removed in modern versions of slack-ruby-client.
