# HA YAML DRY Verifier (Codex Skill)
This directory contains the `homeassistant-yaml-dry-verifier` skill and the CLI used to detect repeated YAML structures in Home Assistant automations/scripts/packages.
### Quick navigation
- You are here: `codex_skills/homeassistant-yaml-dry-verifier/`
- [Repo overview](../../README.md) | [Codex skills](../README.md) | [Packages](../../config/packages/README.md) | [Scripts](../../config/script/README.md)
## What This Skill Does
- Detects repeated `trigger`, `condition`, `action`, and `sequence` blocks.
- Detects repeated entries inside those blocks.
- Detects duplicate entries within a single block (`INTRA`).
- Detects package-defined scripts called from multiple files (`CENTRAL_SCRIPT`).
- Collapses noisy ENTRY reports when they are already fully explained by an identical `FULL_BLOCK` finding.
## CLI Usage
Run on one file:
```bash
python codex_skills/homeassistant-yaml-dry-verifier/scripts/verify_ha_yaml_dry.py config/packages/bearclaw.yaml
```
Run on broader scope:
```bash
python codex_skills/homeassistant-yaml-dry-verifier/scripts/verify_ha_yaml_dry.py config/packages config/script
```
Strict mode (non-zero exit if findings exist):
```bash
python codex_skills/homeassistant-yaml-dry-verifier/scripts/verify_ha_yaml_dry.py config/packages config/script --strict
```
## Output Model
The CLI prints:
- Scan summary counts
- `FULL_BLOCK` findings
- `ENTRY` findings
- `INTRA` findings
- `CENTRAL_SCRIPT` findings
Exit codes:
- `0`: success (or findings in non-strict mode)
- `1`: findings present in strict mode
- `2`: parse/path errors
## Notes
- This verifier intentionally keeps text output and a small CLI surface.
- It does not implement suppression files, severity scoring, JSON output, or diff-only mode.
- Use it as a fast pre-refactor signal and pair with Home Assistant config validation before restart/reload.
