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.

More lookalike characters are scrubbed from output

More lookalike Unicode characters get replaced with "?" before reaching your screen.

What

The sanitizer that replaces arrow-like and private-use Unicode with "?" now covers a much larger set, so fewer confusable glyphs survive into rendered text.

Details
  • Added ranges include mathematical order relations, angle brackets, further Canadian syllabics and more emoji and symbol blocks.
  • The rule that strips a run of arrows at the end of a string now lives in a shared regular expression.

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