SessionEnd — Hook for Claude Code by pdhoolia

SessionEnd

SessionEnd is a hook for Claude Code from pdhoolia/langfuse-claude-code-plugin. Its token cost is not measured, scanned A, original, MIT.

An end-of-session hook that runs a JavaScript file with Node.js when a Claude Code session ends. Node.js is a program that runs JavaScript outside a web browser.

In plain words

What is it for?: Use it to run session-end.js when the session finishes.
Why use it?: It automates a final action at the end of each session instead of relying on someone to run the script manually.

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

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.

Part of the langfuse-tracing plugin — 2 commands, 9 hooks shipped together

One of 9 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 8 are separate, each on its own page.

Good fit Use it to run session-end.js when the session finishes.

Security

Grade A, and why

SessionEnd 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 2mo 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.

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.
