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.

Effort Level Indicator

What

A visual indicator in the input box border now shows the current reasoning effort level (low, medium, high, or max) using colored block characters.

Details
  • Displays 1–3 filled blocks based on effort level (1 for low, 2 for medium, 3 for high/max)
  • Shows alongside model name and /fast mode indicator when present
  • Controlled by existing effort level settings
Evidence

Effort-to-dots mapping function (search for "▪") and effort indicator builder $Qq/Cgz at line ~258963

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