SessionStart

A session-start hook that runs a shell command when a coding session begins. It checks whether the OpenTradex gateway is running on local port 3210.

In plain words
What is it for?
Starting coding sessions that use OpenTradex. It helps confirm that the local trading service is reachable.
Why use it?
It removes the need to check the gateway manually before using OpenTradex. It reports whether the service is available and how to start it if it is not.

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

SessionStart scanned grade A with 1 finding 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 2d 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.

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.
