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.

Remainder of this group is minifier churn, not behaviour

Under the hood
Useful1 Signal0
Elsewhere

Most changes here are renamed internals with identical behaviour, including unchanged upload and watcher limits.

What

Most of the added and removed one-liners in this area are renames of identical code between builds, with no user-visible effect found.

Details
  • The sandbox marker helper still builds CMD64_-prefixed log tokens with the same regex.
  • The color-error helper still produces the same No color named "..." text.
  • The skills watcher's polling constant and the review-mode finderBudgetHint helper, which always returns false, both survive under new names.
  • The design-consent global setter/getter pair is unchanged in substance.
  • Numeric constants match v2.1.218 under different symbol names, including the 67108864 upload cap, the 0.7 voice-meter smoothing factor and the watcher intervals.
Evidence

No color named "

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