SessionStart

SessionStart is a hook for Claude Code from Scoundrelwildness456/i-have-adhd. Its token cost is not measured, scanned A, original, MIT.

A startup hook that runs a Node.js script when a coding-agent session starts, resumes, is cleared, or is compacted. A hook is an automatic action triggered by one of these session events.

In plain words
What is it for?
Use it to connect session lifecycle events to the i-have-adhd persistence check and keep that setting available after startup, resume, clearing, or context compaction.
Why use it?
It ensures the session checks the i-have-adhd always-on setting at the moments when session state may change.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

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 7d 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.
