Source Intelligence

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.

Truncated task output now admits when the full text couldn't be saved to file.

What

When Claude Code truncates a task's output, the footer used to promise the whole thing had been written to a file. If the writer is failing or has lost data, it now says the full output could not all be saved and that the file may be missing or incomplete.

Details
  • A new cleanup path flushes the output writer and logs, at error level, how many characters were discarded unwritten.
  • The message is assembled at runtime from the writer's state; there is no flag.
Evidence

The full output could not all be saved to

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
