Notification

The Notification skill handles non-Slack notification channels. It supports generic webhooks, Discord, and Microsoft Teams — configure whichever channels your team uses. For Slack, use the dedicated Slack skill instead.

Metadata

Field	Value
ID	notification
Category	notification
Required env vars	At least one of: NOTIFICATION_WEBHOOK_URL, DISCORD_WEBHOOK_URL, TEAMS_WEBHOOK_URL (skill also declares SMTP_URL for future email support)

Configuration

All config fields are optional. Set the ones for the channels you want to use.

Env var	Description
NOTIFICATION_WEBHOOK_URL	Generic webhook URL — receives a JSON POST
DISCORD_WEBHOOK_URL	Discord webhook URL
TEAMS_WEBHOOK_URL	Microsoft Teams webhook URL
The skill activates when at least one of the above is set. If none are set, the skill will not appear in the available tool set.

Email notifications

Email notifications are available via the GitHub Action’s notification-provider: email setting with SendGrid (sendgrid-api-key, email-from, email-to inputs). Email is not exposed as a Claude tool — it’s handled by the action’s notification layer.

Tools

Tool	Description
notify_webhook	Send a JSON payload to a webhook URL
notify_discord	Send a message to Discord with optional rich embeds
notify_teams	Send a MessageCard to Microsoft Teams

notify_webhook

Posts an arbitrary JSON payload to NOTIFICATION_WEBHOOK_URL (or a URL specified in the tool input). Useful for integrating with custom automation, PagerDuty, Opsgenie, or any service that accepts webhook POSTs.

notify_discord

Posts to your Discord channel via webhook. Supports Discord’s embed format for rich messages with titles, descriptions, colored sidebars, and inline fields.

notify_teams

Sends a MessageCard to Microsoft Teams via an incoming webhook. Supports a title, markdown body text, and a theme color for the card accent.

Setup

Discord

1. In your Discord server, go to Channel Settings > Integrations > Webhooks.
2. Create a new webhook and copy the URL.
3. Set the environment variable:

export DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/..."

Microsoft Teams

1. In your Teams channel, go to Connectors > Incoming Webhook.
2. Create a webhook and copy the URL.
3. Set the environment variable:

export TEAMS_WEBHOOK_URL="https://outlook.office.com/webhook/..."

Generic webhook

Set the URL of any service that accepts JSON POST requests:

export NOTIFICATION_WEBHOOK_URL="https://your-service.example.com/webhook"

The notify_webhook tool also accepts a url parameter in its input, which overrides the environment variable. This lets Claude target different webhook endpoints dynamically.

Workflow usage

Triage workflow:

• notify — Send the triage summary to Discord, Teams, or a webhook.

Implement workflow:

• notify — Send the implementation result with issue and PR links.

The Notification skill is interchangeable with the Slack skill at notification nodes. You can configure both — Claude will use all available notification tools at the node.
