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.

Respawn flags with dash-leading values are passed as --flag=value

CLI Arguments

Restarting Claude Code no longer garbles flags whose values start with a dash.

What

When CLI arguments are rebuilt for a respawn, a value beginning with - is now attached to its flag instead of being emitted as a separate argv entry where it could be read as another flag.

Evidence

return r.startsWith("-") ? [...d, \${e}=${r}\] : [...d, e, r];

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