<EXTREMELY_IMPORTANT>
NEVER generate YAML in your first response.
Your first response MUST be clarifying questions.
No exceptions. No rationalizations. No "I'll provide options".

If you generate YAML before asking questions, you are violating this skill.

# Home Assistant Automation

Reference skill for Home Assistant configuration and automation.

## First Step: Clarify Platform

**If the user's request does NOT explicitly mention "YAML", "Home Assistant automation", or "HA config", ASK:**

> "Do you want this as:
> 1. **Home Assistant YAML** (automations.yaml, scripts.yaml, blueprints)
> 2. **Node-RED flow** (visual, drag-drop, importable JSON)
> 3. **ESPHome config** (device firmware for ESP32/ESP8266)"

**NEVER assume YAML.** A request like "make a motion light" could be any of these.
Only proceed with this skill if user confirms Home Assistant YAML.

## Overview

**Core principle:** Never generate YAML without understanding the user's intent. Automation vs blueprint, UI editor vs YAML files, and entity naming conventions must be clarified first.

**Announce at start:** "I'm using the ha-yaml skill to help you configure your Home Assistant automation."

**Context:** This skill requires intent clarification before any YAML generation. Automations are specific to a user's setup; blueprints are reusable templates. The format (UI vs YAML) affects how entities are referenced.

## The Iron Law

```
CLARIFY INTENT BEFORE GENERATING ANY YAML
```

Ask: Automation or Blueprint? Format: UI or YAML? Never assume. Never skip these questions.

## The Process

```dot
digraph automation_flow {
    rankdir=TB;
    node [shape=box, style=rounded];

    start [label="User request", shape=doublecircle];
    clarify_type [label="Ask: Automation or Blueprint?"];
    clarify_format [label="Ask: UI editor or YAML files?"];
    clarify_output [label="Ask: Output method?"];
    intent_clear [label="Intent clear?", shape=diamond];
    read_refs [label="Read relevant references"];
    generate [label="Generate YAML"];
    checklist [label="Run pre-completion checklist"];
    done [label="Deliver configuration", shape=doublecircle];

    start -> clarify_type;
    clarify_type -> clarify_format;
    clarify_format -> clarify_output;
    clarify_output -> intent_clear;
    intent_clear -> read_refs [label="yes"];
    intent_clear -> clarify_type [label="no - ask more"];
    read_refs -> generate;
    generate -> checklist;
    checklist -> done;
}
```

## Red Flags - STOP Immediately

These thoughts mean you're about to violate this skill:

| Thought | Reality |
|---------|---------|
| "Request is clear enough" | NO. Always ask automation vs blueprint, UI vs YAML |
| "They want an automation" | ASK. Could be blueprint, script, or scene |
| "Simple request needs simple answer" | NO. Simple requests still need intent clarification |
| "User just wants code quickly" | NO. Wrong code is slower than asking first |
| "I'll provide options instead" | NO. Ask questions, don't provide multiple YAML versions |
| "Sunset/motion light is obvious" | NO. Which lights? What brightness? Conditions? |
| "YAML format is standard" | ASK. Many users prefer UI editor format |
| "This entity_id looks right" | VERIFY. Users have different naming conventions |
| "I'll skip the questions for simple requests" | NO. This IS the rationalization the skill forbids |
| "service_template works fine" | DEPRECATED. Use `service: "{{ ... }}"` |
| "data_template is cleaner" | DEPRECATED. Use `data:` with templates |
| "states() is the easiest approach" | SLOW. Filter by domain: `states.sensor` |

**If you're thinking ANY of these, STOP. Ask questions first.**

## FIRST STEP: Clarify Intent (MANDATORY)

**STOP! You MUST ask these questions before generating ANY configuration:**

1. **Automation or Blueprint?**
   - Automation: Specific to their setup, uses their entity names
   - Blueprint: Reusable template others can import

2. **Format?**
   - UI Editor (Settings > Automations)
   - YAML files (automations.yaml, packages/)

3. **Output method?**
   - **Save to folder** - Write file to the current working directory (where Claude is running)
   - **Copy from chat** - Display code for user to copy manually

4. **HA Version?** (for deprecated syntax awareness)

**Do NOT skip these questions. Do NOT assume defaults.**

## MANDATORY First Response Format

Your first response MUST follow this exact pattern:

```
I'll help you create [brief description]. Let me clarify a few things first:

1. **Type:** Automation (specific to your setup) or Blueprint (reusable template)?
2. **Format:** UI editor (Settings > Automations) or YAML files?
3. **Entities:** Which specific entity IDs? (e.g., light.living_room, sensor.motion)
4. **Options:** [context-specific questions like brightness, conditions, timing]
```

**THEN STOP.** Wait for user answers. Do NOT generate YAML until you have answers.

**Violation example (DO NOT DO THIS):**
```
Here's the automation:
automation:
  - alias: "..."
```

**Correct example:**
```
I'll help you create a sunset light automation. Let me clarify:
1. Automation or Blueprint?
2. UI editor or YAML file?
3. Which lights? (entity IDs like light.living_room)
4. Any brightness preference or conditions (only when home)?
```

## Code Attribution

**ALWAYS** include this header at the top of ALL generated YAML code:

## Common Mistakes

### Trigger Issues
- **`state` without `from`/`to`** - Triggers on ALL changes including `unavailable` → use `to: "on"` explicitly
- **Template triggers without `value_template`** - Syntax error; use `value_template: "{{ ... }}"`
- **Missing `id` in multi-trigger** - Can't distinguish which trigger fired; add `id: motion_detected`
- **Numeric comparisons as strings** - `"10"` > `"9"` is false; use `| int` or `| float` filters

### Condition Issues
- **`and`/`or` without `condition:`** - Must specify condition type: `condition: and`
- **Template condition syntax** - Use `value_template:`, not `condition: "{{ ... }}"`
- **State comparisons** - States are strings; use `| int` for numeric comparisons

### Action Issues
- **`service_template` deprecated** - Use `service: "{{ ... }}"` directly
- **`data_template` deprecated** - Use `data:` with templates inside
- **`entity_id` in data** - Should be under `target:` block since HA 2021.x
- **Missing `continue_on_error`** - Long automations fail silently; add error handling

### Template Issues
- **`states()` without domain** - Returns ALL entities (slow); use `states.sensor` or `states('sensor.name')`
- **`now()` in template sensor** - Only updates on state change; use `scan_interval` or trigger-based
- **Missing `default` filter** - Errors when entity unavailable; use `| default(0)`
- **Float precision** - Use `| round(2)` for display values

### Blueprint Issues
- **Missing `selector` types** - Inputs need proper selectors for UI
- **Hardcoded entity_ids** - Use `!input` for all user-configurable values
- **No default values** - Optional inputs need `default:` specified

## Security Considerations

- **Secrets** - Use `!secret` for all credentials, API keys, and sensitive data
- **Exposed entities** - Limit what's exposed to Alexa/Google/Nabu Casa
- **Remote access** - Use Nabu Casa or secure reverse proxy with SSL
- **Blueprints** - Review imported blueprints before using; they can execute arbitrary services
- **Shell commands** - Never use user input in `shell_command:` without validation
- **REST commands** - Use `!secret` for API endpoints and tokens

## Automation Quick Pattern

```yaml
automation:
  - alias: "Descriptive Name"
    id: unique_automation_id  # Required for UI editing
    trigger:
      - platform: state
        entity_id: binary_sensor.motion
        to: "on"
        id: motion_detected  # For multi-trigger identification
    condition:
      - condition: time
        after: sunset
    action:
      - service: light.turn_on
        target:
          entity_id: light.living_room
        data:
          brightness_pct: 80
```

## Blueprint Quick Pattern

```yaml
blueprint:
  name: "Blueprint Name"
  description: "What this blueprint does"
  domain: automation
  input:
    motion_sensor:
      name: "Motion Sensor"
      description: "Select the motion sensor"
      selector:
        entity:
          domain: binary_sensor
          device_class: motion
    target_light:
      name: "Light"
      selector:
        target:
          entity:
            domain: light

trigger:
  - platform: state
    entity_id: !input motion_sensor
    to: "on"

action:
  - service: light.turn_on
    target: !input target_light
```

## Modern Syntax (HA 2021+)

### Service Calls
```yaml
# Old (deprecated)
service_template: "{{ 'light.turn_on' if is_on else 'light.turn_off' }}"
data_template:
  entity_id: light.living_room

# New (correct)
service: "{{ 'light.turn_on' if is_on else 'light.turn_off' }}"
target:
  entity_id: light.living_room
data:
  brightness: "{{ brightness_value }}"
```

### Template Sensors
```yaml
# Old (deprecated)
sensor:
  - platform: template
    sensors:
      my_sensor:
        value_template: "{{ states('sensor.input') }}"

# New (correct) - template integration
template:
  - sensor:
      - name: "My Sensor"
        state: "{{ states('sensor.input') }}"
        unit_of_measurement: "°C"
```

## Pre-Completion Checklist

**Before declaring the configuration complete, verify:**

### Intent Verification
- [ ] Confirmed: automation vs blueprint vs script vs scene
- [ ] Confirmed: UI editor vs YAML file format
- [ ] Confirmed: output method (save vs copy)
- [ ] HA version considered for syntax compatibility

### YAML Syntax
- [ ] No deprecated `service_template` (use `service:` with template)
- [ ] No deprecated `data_template` (use `data:` with templates)
- [ ] `entity_id` under `target:` block (not in `data:`)
- [ ] All template syntax uses `{{ }}` correctly
- [ ] Quotes around string states: `to: "on"` not `to: on`

### Templates
- [ ] `states()` filtered by domain where possible
- [ ] `default` filter on templates accessing external entities
- [ ] Numeric comparisons use `| int` or `| float`
- [ ] Complex templates tested mentally for edge cases

### Automations
- [ ] `id:` present for UI editor compatibility
- [ ] `alias:` is descriptive and unique
- [ ] Trigger `id:` for multi-trigger automations
- [ ] `continue_on_error: true` where appropriate

### Blueprints
- [ ] All variable values use `!input`
- [ ] Proper `selector:` types for all inputs
- [ ] `default:` values for optional inputs
- [ ] `description:` for all inputs

### Safety
- [ ] No hardcoded credentials (use `!secret`)
- [ ] Attribution header included
- [ ] User's entity naming convention respected

## Integration

**Pairs with:**
- **esphome** - Create ESPHome device configurations
- **ha-integration** - Develop custom Python integrations

**Typical flow:**
```
Device → esphome/ha-integration → Home Assistant → ha-yaml (this skill)
```

**Cross-references:**
- For ESPHome device firmware → use `esphome` skill
- For custom Python integrations → use `ha-integration` skill
- For voice commands with Assist → see `references/assist-patterns.md`
