Claude wrote a parser that pulls the assistant text out of a fake
Anthropic response. The chain uses strict [] access at every
level. If the response was filtered (no content array), the
parser crashes with KeyError.
Replace the strict chain on line 2 with the safe pattern: default
content to [], return the string "(blocked)" if the list is
empty, otherwise pull the first block's text out with .get().
The starter has a content-filtered response (no content key).
Expected output:
(blocked)
The break is on line 2 — but read the whole snippet first.
