Channel Monitor Module

The channel monitor module allows you to monitor slack channels and send slack messages based on the message, a prompt, and an executable.

Configuration

To enable channel monitor, set the environment variable RATCHET_CHANNEL_MONITOR_CONFIG_FILE to the path of the configuration file.

The configuration file contains a set of channel monitor configurations. Each configuration contains the following fields:

• channel_id: the id of the slack channel to monitor, e.g. C0123ABC, the app needs to be added to the channel
• prompt: The prompt to send to the llm to process. The prompt uses golang's text template to render.
• result_schema: The schema of the response you expect from the llm. The schema is a json object, but in yaml format.
• executable: The executable to run to process the message. The executable takes input via stdin and outputs to stdout.
• executable_args: List of arguments to pass to the executable.

Prompt Template Variables

The prompt template has access to the following variables:

• {{.Message.Text}} - The text of the message
• {{.Message.User}} - The slack ID of the user who sent the message

Executable Input JSON

The executable reads a json object from stdin with the following fields:

• slug: The key of the channel monitor configuration entry
• channel_id: The id of the slack channel being monitored
• slack_ts: The timestamp of the slack message
• llm_output: The output of the llm as a string of escaped json
• message: Information about the original slack message
  • text: The text of the message
  • user: The slack ID of the user who sent the message

Executable Output JSON

The executable should output a json object with the following fields:

• direct_messages: A list direct messages to send
  • email: The email of the user to send the message to
  • text: The text of the message
• channel_messages: A list of channel messages to send
  • channel_id: The id of the channel to send the message to
  • text: The text of the message
  • slack_ts: The timestamp of the slack message to reply to (optional)

Example Configuration

In this example, we monitor a channel for questions about kubernetes. The monitor will send a DM to a specified user if the llm determines the message is a question about kubernetes and user is asking for help.

channel_monitor_1:
    channel_id: C0123ABC
    prompt: >
      If the message below the horizontal line is asking a question about the kubernetes cluster, respond with {"help": true}. Otherwise, respond with {"help": false}.

        properties:
            help:
                type: boolean
    executable: jq
    executable_args: 
        - '(.llm_output | fromjson | .help) as $help | if $help then {"direct_messages": [{"email": "mike@example.com", "text": "User posted message in channel asking about k8s: \(.message.text)"}]} else {} end'
