PreToolUse

PreToolUse is a hook for coding agents from adongwanai/adong-vibecoding. Its token cost is not measured, scanned A, original, no licence file.

A pre-tool hook that checks selected commands before the agent runs them, including development servers, package installation, tests, builds, Docker, and related tasks.

In plain words
What is it for?
Use it to apply automatic checks before selected shell commands and development tasks.
Why use it?
It can inspect or control risky or important operations before they start.

Hook

Part of the adong-vibecoding plugin — 11 skills, 15 commands, 9 agents, 6 hooks shipped together

One of 6 entries in hooks.json — they are configured in one file and arrive together.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add hooks/adongwanai/adong-vibecoding/pre-tool-use
Clone the repo
git clone --depth 1 https://github.com/adongwanai/adong-vibecoding

Or install adong-vibecoding, the plugin that ships this one along with the rest of its 11 skills, 15 commands, 9 agents, 6 hooks.

Security

Grade A, and why

PreToolUse 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 5d 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.
