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.

DISABLE_INSTALLATION_CHECKS parsed rather than tested for presence

Use it now
Useful3 Signal2
Installation Notable not in their notes

DISABLE_INSTALLATION_CHECKS now reads its value, so 0 or false means off.

DISABLE_INSTALLATION_CHECKS
What

The installation check now parses the value of DISABLE_INSTALLATION_CHECKS instead of treating any set value as true, so 0 and false should now read as off rather than switching the checks off.

Evidence

DISABLE_INSTALLATION_CHECKS

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