SessionStart

SessionStart is a hook for coding agents from FruityMaxine/claude-quotas. Its token cost is not measured, scanned A, original, MIT.

A session-start hook that runs a Node.js script when a Claude session is resumed. A hook is an automatic action triggered by an event.

In plain words
What is it for?
Use it to run the provided session-start script on resume, with a five-second time limit.
Why use it?
It automates work that should happen at the start of a resumed session instead of relying on a person to run it.

Hook

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code
/plugin marketplace add FruityMaxine/claude-quotas
Claude Code
/plugin install claude-quotas

Or install claude-quotas, the plugin that ships this one along with the rest of its 1 skill, 1 hook, 1 MCP server.

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 4d 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.
