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.

Claude Code v2.1.191

Ghostty Terminal Detection

What changed: Claude Code can now detect when it is running inside the Ghostty terminal emulator, enabling any terminal-specific rendering or feature adjustments. Detection is based on the TERM_PROGRAM environment variable starting with "ghostty" (case-insensitive).

Evidence

Ghostty detection check (search for "ghostty" near "toLowerCase")

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