What is SessionStart?

A session-start hook that checks whether the ds-rescue command-line program is installed when a coding session begins. If it is missing, it prints installation guidance.

Use it to verify ds-rescue is available at the start of each session and show the recommended installation command when it is not.

It warns about a missing dependency early, before a review command fails unexpectedly.

Security

Grade C, and why

SessionStart scanned grade C with 2 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.

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.
