dbt-patterns

dbt-patterns is a skill for Claude Code, Codex from sawrus/agent-guides. It costs 0 tokens per session (263 once invoked), scanned A, original, MIT.

Coding conventions for dbt, a tool that turns SQL queries into organized, tested data models.

In plain words
What is it for?
They guide dbt models, SQL macros, incremental updates, table partitioning, materializations, and audit columns.
Why use it?
They provide consistent choices for how source data is staged, transformed, stored, updated, and audited.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

dbt-patterns 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 4d 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.

What it actually says

Skill: dbt Development Patterns

When to load

When building dbt models, writing macros, or configuring materializations.

Materialization Strategy

Layer Materialization Why
staging/ view Always reflects source
intermediate/ ephemeral Reduce clutter
marts/ table or incremental Pre-computed for BI

Incremental Model

{{
    config(
        materialized='incremental',
        unique_key='order_id',
        incremental_strategy='merge',
        partition_by={'field': 'order_date', 'data_type': 'date'},
    )
}}

SELECT order_id, user_id, order_date, total_amount
FROM {{ ref('stg_orders') }}

{% if is_incremental() %}
    WHERE order_date >= (SELECT MAX(order_date) FROM {{ this }}) - INTERVAL '3 days'
{% endif %}

Audit Columns Macro

{% macro audit_columns() %}
    CURRENT_TIMESTAMP AS loaded_at,
    '{{ invocation_id }}' AS dbt_invocation_id,
    '{{ this.name }}' AS dbt_model
{% endmacro %}

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.

dbt-patterns is a skill published in the GitHub repository sawrus/agent-guides (17 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 263 tokens. 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 2026-08-30.
