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.

Command analysis sees through wrappers and ignores benign env prefixes

Under the hood
Useful3 Signal3
Permissions

Command parsing now looks past wrappers like sudo and timeout and ignores harmless variable prefixes.

What

Bash command parsing gained two lists: shells and wrappers to look past when finding the real command (sudo, doas, xargs, timeout, nsenter and more), and environment variables treated as harmless when prefixed onto a command (GOEXPERIMENT, RUST_LOG, NO_COLOR, CI, ANTHROPIC_API_KEY among them), with a matching VAR= assignment pattern.

PYTEST_DISABLE_PLUGIN_AUTOLOAD

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