- Claude Code numbers piled-up permission prompts, survives model refusals, and stops leaking secrets in logs.
- What it is: Claude Code 2.1.286 shows a count such as "2 of 5" when several permission requests stack up. When the Anthropic API refuses the model your default or alias points to, every turn used to fail; now the CLI retries once on the previous model of the same tier. The VS Code extension adds bookmarks for saving Claude's answers in a side panel.
