migrating-sql-to-dbt SKILL.md skillA
migrating-sql-to-dbt from altimateai/data-engineering-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Converts legacy SQL to modular dbt models. Use when migrating SQL to dbt for: (1) Converting stored procedures, views, or raw SQL files to dbt models (2) Task mentions "migrate", "convert", "legacy SQL", "transform to dbt", or "modernize" (3) Breaking monolithic queries into modular layers (discovers project conventions first) (4) Porting existing data pipelines or ETL to dbt patterns Checks for existing models/sources, builds and validates layer by layer.
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
# dbt Migration
**Don't convert everything at once. Build and validate layer by layer.**
## Workflow
### 1. Analyze Legacy SQL
```bash
cat <legacy_sql_file>
```
Identify all tables referenced in the query.
### 2. Check What Already Exists
```bash
# Search for existing models/sources that reference the table
grep -r "<table_name>" models/ --include="*.sql" --include="*.yml"
find models/ -name "*.sql" | xargs grep -l "<table_name>"
```
For each table referenced in the legacy SQL:
1. Check if an existing model already references this table
2. Check if a source definition exists
3. If neither exists, ask user: "Table X not found - should I create it as a source?"
Only proceed to intermediate/mart layers after all dependencies exist.
### 3. Create Missing Sources
```yaml
# models/staging/sources.yml
version: 2
sources:
- name: raw_database
schema: raw_schema
tables:
- name: orders
description: Raw orders from source system
- name: customers
description: Raw customer records
```
### 4. Build Staging Layer
One staging model per source table. Follow existing project naming conventions.
**Build before proceeding:**
```bash
…Read the whole file at its exact version.
How to install
mdr add altimateai/data-engineering-skills/migrating-sql-to-dbt@sha256:38c6cae440d34dbaThe line at the top of this page pins the label git:20260121.476f750, 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.
