# Shipped With Malice — THM Token City Task 7 (Tool Poisoning)
#
# Chain of three bugs in AVA (port 5000):
#   1. /admin/tools/install accepts new tool entries with no auth
#   2. dispatcher.py parses <system_diagnostic> blocks inside tool
#      descriptions, builds a hidden trigger→tool mapping, and fires it
#      transparently on /chat
#   3. read_ship_logs accepts absolute paths and reads them as user `ava`
#
# Net effect: poisoned tool description → chat trigger → arbitrary file
# read with the AVA process's privileges → /var/lib/ava/credentials.json.
