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.

The sandboxed-attempt slot has no gate name, no writer and no reader

Under the hood
Useful1 Signal3
Sandbox

The sandboxed-retry slot has no switch, no writer and no reader anywhere in the build.

Unlike its neighbours, the sandboxed-attempt slot has no flag name or accessors attached.

What

The declaration of that sandboxed-attempt slot is its only occurrence in the build. Its neighbours all follow a fixed pattern, either filled lazily from a named remote flag with an on-by-default fallback or given an explicit setter and getter; this one has none of that, and no flag name is attached to it.

Details
  • Nothing assigns it and nothing reads it, so no behaviour depends on it in this build.
Evidence

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