UserPromptSubmit

UserPromptSubmit is a hook for coding agents from aris4u-dev/aris4u. Its token cost is not measured, scanned A, original, no licence file.

A set of commands that runs whenever you submit a prompt, before the coding agent receives it. The commands dispatch the request, add build hints, check whether clarification is needed, and provide governing context.

In plain words
What is it for?
Use it to prepare prompts, add relevant context, and enforce clarification or build-related rules before work begins.
Why use it?
It applies project or organisation checks before the agent starts handling your request.

Hook

Part of the aris4u plugin — 25 skills, 15 agents, 7 hooks, 1 MCP server shipped together

One of 7 entries in hooks.json — they are configured in one file and arrive together.

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/aris4u-dev/aris4u/user-prompt-submit
Clone the repo
git clone --depth 1 https://github.com/aris4u-dev/aris4u

Or install aris4u, the plugin that ships this one along with the rest of its 25 skills, 15 agents, 7 hooks, 1 MCP server.

Security

Grade A, and why

UserPromptSubmit 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 3d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What else hooks.json configures

This page is one entry in a file that holds 7. Installing the file brings all of them; each is measured and scanned on its own page.

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.
