sqlmesh

sqlmesh is a skill for Claude Code from jpoutrin/product-forge. It costs 35 tokens per session (418 once invoked), scanned A, original, MIT.

A set of SQLMesh patterns for transforming raw data into organized datasets. SQLMesh is a data-pipeline tool that tracks dependencies between models, supports incremental processing, testing, and separate development environments.

In plain words
What is it for?
Use it to define full or incremental models, process data by time range or key, create development plans, check for errors such as null IDs, and manage static seed data.
Why use it?
It helps teams update large datasets efficiently while showing how models depend on one another. Virtual environments and audits also provide ways to test changes and catch invalid data.

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

sqlmesh 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 1mo 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.

Model Definition

-- models/staging/stg_customers.sql
MODEL (
    name staging.stg_customers,
    kind INCREMENTAL_BY_TIME_RANGE (
        time_column created_at
    ),
    cron '@daily'

SELECT

    LOWER(email) AS email,
    created_at
FROM raw.customers
WHERE created_at BETWEEN @start_ds AND @end_ds

Model Kinds

Kind Use Case
FULL Complete refresh each run
INCREMENTAL_BY_TIME_RANGE Time-based incremental
INCREMENTAL_BY_UNIQUE_KEY Key-based merge
VIEW Virtual table
SEED Static CSV data

Virtual Environments

# Create a virtual environment for testing
sqlmesh plan dev

# Apply to production
sqlmesh plan prod

Audits

-- audits/no_nulls.sql
AUDIT (
    name assert_no_null_customer_id,
    model staging.stg_customers
);

SELECT * FROM staging.stg_customers
WHERE customer_id IS NULL

Best Practices

  • Use column-level lineage for impact analysis
  • Leverage virtual environments for testing
  • Define audits for data quality
  • Use incremental models for efficiency

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.

sqlmesh is a skill published in the GitHub repository jpoutrin/product-forge (16 stars, last pushed 7mo ago), licensed MIT. It adds 35 tokens to every session and 418 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
