SessionStart

SessionStart is a hook for coding agents from idean3885/claude-ops-agent. Its token cost is not measured, scanned A, original, no licence file.

A session-start hook that runs two Node.js scripts when a coding-agent session begins.

In plain words
What is it for?
It runs the session-start script and applies a heads-up display patch through Bash.
Why use it?
It performs setup actions automatically at the start of a session instead of requiring the user to run them manually.

Hook

Part of the ops-agent plugin — 10 skills, 2 agents, 7 hooks 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/idean3885/claude-ops-agent/session-start
Clone the repo
git clone --depth 1 https://github.com/idean3885/claude-ops-agent

Or install ops-agent, the plugin that ships this one along with the rest of its 10 skills, 2 agents, 7 hooks.

Security

Grade A, and why

SessionStart 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.

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.
