Creates event-driven email listeners that monitor for specific conditions (like urgent emails from boss, newsletters to archive, package tracking) and execute custom actions. Use when user wants to be notified about emails, automatically handle certain emails, or set up email automation workflows.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Listener Creator
Creates TypeScript listener files that monitor email events and execute custom logic when conditions are met.
## When to Use This Skill
Use this skill when the user wants to:
- Get notifications about specific emails ("notify me when boss sends urgent emails")
- Automatically handle certain emails ("auto-archive newsletters")
- Monitor for patterns ("watch for package tracking emails")
- Set up scheduled actions ("daily email summary at 9am")
- Create custom email workflows
## How Listeners Work
Listeners are TypeScript files in `agent/custom_scripts/listeners/` that:
1. Export a `config` object defining the event type and metadata
2. Export a `handler` function that filters and processes events
3. Use `ListenerContext` methods to perform actions (notify, archive, star, etc.)
The system automatically loads enabled listeners and executes them when matching events occur.
## Creating a Listener
### 1. Understand the User's Intent
Parse the user's request to identify:
- **Event type**: What triggers this listener? (email_received, email_sent, email_starred, email_archived, email_labeled, scheduled_time)

How to install
mdr add trustabl/agent-reliability-analyzer/listener-creator@sha256:9bc83291b47f1385The line at the top of this page pins the label git:20260527.58ef39d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
