## talk-plugin-deep-reply-count

Source: [plugins/talk-plugin-deep-reply-count](https://github.com/coralproject/talk/tree/master/plugins/talk-plugin-deep-reply-count){:target="_blank"}

Enables counting of comments to include replies via a new graph edge. Not
recommended for large installations as it will unreasonably reduce the query
efficiency to compute this number.

## talk-plugin-slack-notifications

Source: [plugins/talk-plugin-slack-notifications](https://github.com/coralproject/talk/tree/master/plugins/talk-plugin-slack-notifications){:target="_blank"}

Enables all new comments that are written to be posted to a Slack channel as
well. Configure an
[Incoming Webhook](https://api.slack.com/incoming-webhooks){:target="_blank"}
app and provide that url in the form of the `SLACK_WEBHOOK_URL`
detailed below.

*Warning: On high volume sites, this means every single comment will flow into
Slack, if this isn't what you want, be sure to use the provided plugin as a
recipe to further customize the behavior*.

Configuration:

- `SLACK_WEBHOOK_URL` (**required**) - The webhook url that will be
  used to post new comments to.

## talk-plugin-toxic-comments

Source: [plugins/talk-plugin-toxic-comments](https://github.com/coralproject/talk/tree/master/plugins/talk-plugin-toxic-comments){:target="_blank"}

Using the [Perspective API](http://perspectiveapi.com/){:target="_blank"}, this
plugin will warn users and reject comments that exceed the predefined toxicity
threshold. For more information on what Toxic Comments are, check out the
[Toxic Comments]({{ "/toxic-comments/" | relative_url }}) documentation.

Configuration:

- `TALK_PERSPECTIVE_API_KEY` (**required**) - The API Key for Perspective. You
  can register and get your own key at [http://perspectiveapi.com/](http://perspectiveapi.com/){:target="_blank"}.
- `TALK_TOXICITY_THRESHOLD` - If the comments toxicity exceeds this threshold,
  the comment will be rejected. (Default `0.8`)
- `TALK_PERSPECTIVE_API_ENDPOINT` - API Endpoint for hitting the
  perspective API. (Default `https://commentanalyzer.googleapis.com/v1alpha1`)
- `TALK_PERSPECTIVE_TIMEOUT` - The timeout for sending a comment to
  be processed before it will skip the toxicity analysis, parsed by
  [ms](https://www.npmjs.com/package/ms){:target="_blank"}. (Default `300ms`)

## talk-plugin-subscriber

Source: [plugins/talk-plugin-subscriber](https://github.com/coralproject/talk/tree/master/plugins/talk-plugin-subscriber){:target="_blank"}

Enables a `Subscriber` badge to be added to comments where the author has the
`SUBSCRIBER` tag. This must match with a custom auth integration that adds the
tag to the users that are subscribed to the service.
