Slack Bot

Operate Slack Bot through your OOMOL-connected account. This skill calls the slackbot connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action

Assume the user has already installed the oo CLI, signed in, and connected Slack Bot. Do not run oo auth login or open the connection URL proactively — just run the action. Fall back to First-time setup only when a command actually fails with an auth or connection error.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

oo connector schema "slackbot" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

oo connector run "slackbot" --action "<action_name>" --data '<json>' --json

• --data takes a JSON object string or @path/to/file.json; omit it to send {}.
• The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action's live schema with oo connector schema to get its authoritative input fields.

Preserve multiline message text

Slack renders real newline characters in text; it renders literal backslash-n characters as \n. Keep one JSON-encoding boundary:

• Before serialization, message text must contain actual LF characters.
• In serialized JSON, each intended newline appears as \n. If it appears as \\n, it has been double-escaped and Slack will display \n.
• When passing raw JSON to --data, write the JSON newline escape exactly once.

oo connector run "slackbot" \
  --action "post_message" \
  --data '{"channelId":"C123","text":"First paragraph.\n\nSecond paragraph."}' \
  --json

If visible formatting matters, read the posted message back and confirm that text contains line breaks rather than literal \n characters.

• download_file — Download a Slack-hosted file into Connector file transit storage using the connected identity's access.
• get_channel_messages — Get recent messages from a Slack conversation.
• get_conversation — Get metadata for a Slack conversation.
• get_current_user — Get the workspace and user identity of the connected Slack credential.
• get_file — Get metadata for a Slack file.
• get_message_permalink — Get a permalink for a Slack message.
• get_reactions — Get reactions for a Slack message.
• get_thread — Get messages in a Slack thread.
• get_user — Get metadata for a Slack user.
• list_channels — List Slack public channels visible to the connected Slack identity.
• list_conversations — List Slack conversations visible to the connected Slack identity.
• list_files — List Slack files visible to the connected Slack identity, optionally filtered by channel or user.
• list_reactions — List the messages and files a Slack user reacted to, with the reactions on each. Defaults to the connected user.
• list_users — List Slack users visible to the connected Slack identity.
• open_conversation — Open or resume a direct message with one Slack user. [write]
• post_ephemeral_message — Post an ephemeral Slack message visible only to one user in a conversation. [write]
• post_message — Post a Slack message. Use text for plain messages, or blocks for rich Block Kit layouts with text as fallback. [write]
• remove_reaction — Remove an emoji reaction from a Slack message. [destructive]
• reply_message — Reply to a Slack thread. Use text, blocks, or attachments for the reply content. [write]
• schedule_message — Schedule a Slack message to be posted later. Use text or blocks for the scheduled content. [write]
• update_message — Update a Slack message posted through this connection. Provide text, blocks, or attachments as the new message content. [write]
• upload_file — Upload a file to Slack using the current external upload flow. Provide fileUrl; binary content is fetched by the connector runtime. [write]

Safety

• Untagged actions are reads (get / list / search) — safe to run directly.
• Actions tagged [write] change Slack Bot state — confirm the exact payload and effect with the user before running.
• Actions tagged [destructive] remove or overwrite data — always confirm the target and get explicit approval first.

First-time setup

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

• oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):

  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  

  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  

• Not signed in / authentication error — sign in to your OOMOL account once:

  oo auth login
  

• scope_missing / credential_expired / app_not_ready / app_not_found — Slack Bot is not connected, or the connection expired or lacks a scope. Connect once (auth type: OAuth2) at:

  https://console.oomol.com/app-connections?provider=slackbot
  

• HTTP 402 / OOMOL_INSUFFICIENT_CREDIT — billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.
