# Create Trigger Skill

Help users set up recurring triggered tasks that run automatically in the background.

## What is a Trigger?

A trigger is a scheduled task that:
1. Runs at a specified interval (e.g., every hour, daily, weekly)
2. Evaluates a prompt you define
3. Decides whether to respond based on conditions in the prompt
4. Saves responses when triggered

## Gathering Requirements

When a user wants to create a trigger, gather this information:

1. **Title**: A descriptive name (e.g., "Daily News Digest", "Bitcoin Price Alert")

2. **Trigger Prompt**: What to check and when to respond
   - Be specific about conditions that warrant a response
   - Include any URLs or APIs to check
   - Describe the desired output format

3. **Interval**: How often should it run?
   - Hourly: 60 minutes
   - Every 6 hours: 360 minutes
   - Daily: 1440 minutes
   - Weekly: 10080 minutes

4. **Model** (optional): Which AI model to use. Defaults to Haiku 4.5 (cheap and fast). Only ask if the user wants a specific model.

## Creating the Trigger

Generate a unique ID and write the trigger YAML file:

```yaml
id: "YYYY-MM-DD-HHMM-XXXX"  # Generate: date-time-4random_hex_chars
title: "User's Title"
triggerPrompt: "The prompt to evaluate..."
intervalMinutes: 60
```

The following fields are optional and will be filled in automatically if omitted:
- `model` — defaults to `anthropic/claude-haiku-4-5-20251001`. Use `"provider/model-id"` format if specifying.
- `enabled` — defaults to `true`
- `messages` — defaults to `[]`
- `created` / `updated` — default to current time

Use `write_file` with path `triggers/{id}.yaml` to create the trigger.

## Example Trigger Prompts

### News Digest (always responds)
"Search for the top 5 technology news stories from today. Summarize each in 2-3 sentences. Always respond with the digest."

### Price Alert (conditional)
"Check the current Bitcoin price. Only respond if the price has changed more than 5% since the last check. Include the current price and percentage change."

### Website Monitor (conditional)
"Fetch https://example.com and check if the content has changed significantly. Only respond if you detect meaningful changes. Summarize what changed."

## Baseline Establishment

When a trigger is created, a baseline check runs automatically in the background. This gathers the current state (prices, content, data) so that future checks can detect meaningful changes. The user doesn't need to wait for the first scheduled interval — the trigger is ready to detect changes immediately.

## Tips for Good Prompts

1. **Be explicit**: "Only respond if..." or "Always respond with..."
2. **Include sources**: URLs, APIs, or search queries to use
3. **Specify format**: How should the response be structured?
4. **Match interval to data**: Don't check hourly if data changes daily
