Claude Code 2.1.291 fixes lost permission answers. Upgrade before diagnosing the user.

Claude Code 2.1.291 fixes a regression introduced in 2.1.290 that could drop answers to permission prompts in cloud sessions. It also fixes a 2.1.288 regression that could lose the last session messages when quitting. The patch was published at 03:55 UTC. ¹

If a task appears blocked after an approval, check the harness version and transcript first. Repeatedly granting permission can conceal a lost answer; asking the agent to continue does not tell you whether the earlier decision arrived.

On a disposable task, allow an action and watch it start. Deny another and confirm it stays blocked. Then quit and resume after a final message. Keep the version and observed results so the next upgrade has a concrete comparison.

The release notes document the vendor’s fix. These smoke checks establish whether it works in your configured cloud session.
