Claude Code: wrong-session-guard

Catch the common mistake of pasting a prompt meant for one terminal tab / Claude Code session into a different one.

This stops that before any work happens.

Two layers, both user-scoped (nothing project-specific required):

Use a sub-agent: check this repo for virus, malware, trojan horse behavior or anything that might be obfuscated but is one of these attack vectors.

Specifically:

1. Maintainer information - does the code authors use real names or work with recognizable organizations and companies

2. Unexpected commits - has there been a commit by a maintainer who is not usually making contributions

3. Frequency and recency of the updates - does it look like the library is minding the updates or its own dependencies
