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.

Config namespaces merged into one validated registry

Under the hood
Useful2 Signal3
Configuration

All config declarations merged into one registry with range and allowed-value constraints.

What

The typed config declarations are collected into a single object rather than scattered namespaces, giving uniform parsing of environment values. Integer entries can now declare minimum, maximum and digits-only constraints, and some entries carry explicit value lists, such as a policy that must be enforce, observe or off.

Evidence

C.enum(["enforce", "observe", "off"])

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