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.

Claude Code v2.1.139

Supervised Mode Exits on Fatal Runtime Errors

When CLAUDE_CODE_SUPERVISED is set, uncaught exceptions and unhandled rejections now cause the process to exit after logging. This is useful for service managers or wrapper processes that should restart a crashed CLI instead of letting it limp along.

Usage
CLAUDE_CODE_SUPERVISED=1 claude
Evidence

Supervised fatal-error handling (search for "Uncaught exception under CLAUDE_CODE_SUPERVISED — exiting", "Unhandled rejection under CLAUDE_CODE_SUPERVISED — exiting")

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