DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
Reports about malformed incoming messages now record the message's shape rather than a prose description.
What's wrong with this entry?
Anonymous. No account, no email.
What
When an inbound user message is dropped or repaired, the report now carries the message's wire shape and whether it had an event identifier, replacing a free-text English description of the problem.
Details
The same two fields appear on the telemetry event, on the structured log line, and in the debug output.
Evidence
cli_malformed_user_message
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
