Notification

Notification is a hook for Claude Code from kaiiserni/claude-plugin-tmux-notifications. Its token cost is not measured, scanned A, original, MIT.

A notification hook that runs a shell script whenever the coding agent sends a notification. A hook is an automatic action tied to an agent event.

In plain words
What is it for?
Use it to connect agent notifications to shell-based actions, such as displaying or forwarding them through a terminal session.
Why use it?
It lets notifications trigger an external script without requiring a separate manual command. The provided script comes from a tmux notification plugin.

Hook for Claude Code

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 tmux-agent-notifications plugin — 6 hooks shipped together

One of 6 entries in hooks.json — they are configured in one file and arrive together.

Security

Grade A, and why

Notification 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 5d 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.
