Claude Code 2.1.300 ships 88 CLI changes, drops AskUserQuestion directive from system prompt
ClaudeCodeLog · x · 2026-10-15
Claude Code 2.1.300 is out with 88 CLI changes and 1 system prompt change.
CLI highlights:
- virtualText: prompt-box decorations never enter the draft, submitted prompt, or model input
- $.ui.view({agentId}) shows an agent transcript in the main view; $.ui.view({}) returns
- OpenTelemetry apirequest now splits cache writes into cachecreation5mtokens and cachecreation1htokens
- prompt.change hook fires on non-typed edits (history/clear/undo/plugin fill)
- New /advisor on Claude Platform on AWS; CLAUDECODEDISABLEADVISORTOOL=1 disables it
- RTL text support via a dir prop on Text
System prompt: the tracked claude-code-changelog repo shows the explicit "AskUserQuestion" directive was removed, replaced by a "claude-mermaid-runtime-begin" marker injected before the Harness block — shifting from forced question-asking toward a runtime-wrapped instruction section, likely tied to Mermaid handling.
