UserPromptSubmit

A prompt-submission hook that runs a local CodeRLM command before the coding agent sees your prompt. CodeRLM is a code-navigation tool that indexes supported programming languages so the agent can find code structure and relationships.

In plain words
What is it for?
Use it to configure automatic guidance for code exploration, including symbol searches, function lookups, caller tracing, and code extracts.
Why use it?
It automatically reminds the agent to use structured code searches when exploring supported code, while leaving simple files to normal reading and search tools.

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.

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 yesterday.

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.
