Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.01515 |
| Opus 5 | $0.00033 | $0.00758 |
| Sonnet 5 | $0.00013 | $0.00303 |
| Haiku 4.5 | $0.00007 | $0.00152 |
Grade A, and why
homeassistant-config scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Home Assistant Configuration
Create and manage Home Assistant configuration files with proper YAML syntax, automations, scripts, and templates.
When to Use This Skill
Use when working with:
- Main configuration.yaml files and includes
- Automations (triggers, conditions, actions)
- Scripts with parameters
- Jinja2 templates and template sensors
- File organization and splitting
- YAML syntax validation
- Home Assistant troubleshooting
Core YAML Rules
Critical syntax requirements:
- Indentation: 2 spaces per level (never tabs)
- Lists: Start with
-at same indentation - Strings: Quote 'on', 'off', 'yes', 'no' to avoid boolean conversion
- Case sensitive: 'on' ≠ 'On' ≠ 'ON'
- Comments: Use
#
Example structure:
automation:
- alias: "Descriptive Name"
triggers:
- trigger: state
entity_id: sensor.example
actions:
- action: light.turn_on
File Organization
Basic Includes
# configuration.yaml
automation: !include automations.yaml
script: !include scripts.yaml
sensor: !include sensors.yaml
Directory Includes
# Merge as list (files start with -)
automation: !include_dir_list automations/
sensor: !include_dir_merge_list sensors/
# Merge as named dict
script: !include_dir_merge_named scripts/
Secrets Management
Store sensitive data in secrets.yaml (add to .gitignore):
# secrets.yaml
api_key: "abc123"
# configuration.yaml
platform: service
api_key: !secret api_key
Automations
Current Syntax (2024+)
- alias: "Name"
triggers:
- trigger: [type]
conditions:
- condition: [type]
actions:
- action: [service]
Common Triggers
State: trigger: state with entity_id, from, to, for
Time: trigger: time with at
Numeric: trigger: numeric_state with above/below
Sun: trigger: sun with event: sunset/sunrise
Template: trigger: template with value_template
Common Actions
Service call:
- action: light.turn_on
target:
entity_id: light.bedroom
data:
brightness: 255
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

homeassistant-config is a skill published in the GitHub repository narrowstacks/claude-homeassistant-plugins (3 stars, last pushed 10mo ago), licensed MIT. It adds 66 tokens to every session and 1,515 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
