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 v2.1.221

Background session names starting with "-" survive respawn

Sessions

Background sessions renamed to something starting with a dash now restart correctly.

--name-n
What

Renaming a background session to a value beginning with a dash no longer produces argv that the respawned process parses as a flag.

Details
  • The argv rewriter now emits --name=<value> when the new value starts with a dash, instead of leaving the value as a separate argument.
  • Bundled short flags are collapsed when the rewrite happens, and nulled-out argv slots are compacted out of the result.
  • Covers both --name and -n.
Evidence

zpi(c.respawnFlags, "--name", "-n", c.name)

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