PostToolUse

PostToolUse is a hook for Claude Code from sfc-gh-dflippo/snowflake-dbt-demo. Its token cost is not measured, scanned A, original, Apache-2.0.

A set of hooks that run checks after editing files or using shell commands in a Snowflake dbt project. They call scripts that validate changed files and audit the project after dbt commands.

In plain words
What is it for?
Use it to validate edited dbt models, run post-command audits, and connect those checks to write, edit, multi-edit, and shell-tool events.
Why use it?
It catches dbt quality problems automatically after common development actions, rather than relying only on a later manual review. It also reports a status message while checks run.

Hook for Claude Code

Written for Claude Code: PostToolUse hook event.

Part of the dbt-quality plugin — 2 skills, 2 hooks shipped together

One of 2 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

Security

Grade A, and why

PostToolUse 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 commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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 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.
