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.

Rate Limits

Fake usage-limit states for testing ship in the build but every accessor returns nothing.

A rate-limit mock harness covering session limits, overage, seat-tier credits and fast-mode limits is bundled but hard-disabled.

What

A component holding fake usage-limit states (session limit reached, overage exhausted, seat-tier zero credit limit, fast-mode limits, trial and overage payloads) is bundled in this build but cannot affect anything: every accessor that would read it returns null on its first line, leaving the real body unreachable.

Evidence

seat-tier-zero-credit-limit

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