v2.1.126 の変更点：ゲートウェイ連携とプロジェクト状態削除機能の追加

What's changed

• The /model picker now lists models from your gateway's /v1/models endpoint when ANTHROPIC_BASE_URL points at an Anthropic-compatible gateway

• Added claude project purge [path] to delete all Claude Code state for a project (transcripts, tasks, file history, config entry) — supports --dry-run, -y/--yes, -i/--interactive, and --all

• --dangerously-skip-permissions now bypasses prompts for writes to .claude/, .git/, .vscode/, shell config files, and other previously-protected paths (catastrophic removal commands still prompt as a safety net)

• claude auth login now accepts the OAuth code pasted into the terminal when the browser callback can't reach localhost (WSL2, SSH, containers)

• claude_code.skill_activated OpenTelemetry event now fires for user-typed slash commands and carries a new invocation_trigger attribute ("user-slash", "claude-proactive", or "nested-skill")

• Auto mode: the spinner now turns red when a permission check stalls, instead of looking like the tool is running

• Host-managed deployments (CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST) no longer auto-disable analytics on Bedrock/Vertex/Foundry

• Windows: PowerShell 7 installed via the Microsoft Store, MSI without PATH, or .NET global tool is now detected

• Windows: when the PowerShell tool is enabled, Claude now treats PowerShell as the primary shell instead of defaulting to Bash

• Read tool: removed the per-file malware-assessment reminder that could cause spurious refusals and "this is not malware" commentary on legacy models

• Security: Fixed allowManagedDomainsOnly / allowManagedReadPathsOnly being ignored when a higher-priority managed-settings source lacked a sandbox block

• Fixed pasting an image larger than 2000px breaking the session — images are now downscaled on paste, and oversized images in history are automatically removed and the request retried

• Fixed showing the login screen for "OAuth not allowed for organization" errors — now shows guidance to contact your admin

• Fixed OAuth login failing with timeout on slow or proxied connections, in IPv6-only devcontainers, and when the browser callback can't reach localhost

• Fixed a rare race where a concurrent credential write could clear a valid OAuth refresh token

• Fixed API retry countdown sticking at "0s" instead of counting down between attempts

• Fixed "Stream idle timeout" error after waking Mac from sleep mid-request

• Fixed background and remote sessions falsely aborting with "Stream idle timeout" during long model thinking pauses

• Fixed a hang where the assistant could finish thinking but show no output after a run of empty turns

• Fixed overly fast trackpad scrolling in Cursor and VS Code 1.92–1.104 integrated terminals

• Fixed claude.ai MCP connectors being suppressed by manual servers stuck in needs-auth state

• Fixed Japanese/Korean/Chinese text rendering as garbled characters on Windows in no-flicker mode

• Fixed Ctrl+L clearing the prompt input — it now only forces a screen redraw, matching readline behavior

• Fixed deferred tools (WebSearch, WebFetch, etc.) not being available to skills with context: fork and other subagents on their first turn

• Fixed plan-mode tools being unavailable in interactive sessions launched with --channels

• Fixed blank remote-session transcript when certain messaging tools are unavailable

• Fixed /plugin Uninstall reporting "Enabled" instead of "Uninstalled"

• Bounded total size of file-modified reminders when a linter touches many files at once

• Fixed /remote-control retries appearing stuck on "connecting…" — each retry now shows its result, and unenrolled trusted-device failures are caught up-front

• Fixed Remote Control failure notification not showing the error reason for initial connection failures

• Windows: clipboard writes no longer expose copied content in process command-line arguments visible to EDR/SIEM telemetry; also fixes >22KB selections not reaching the clipboard

• PowerShell tool: bare -- (e.g. git diff -- file) is no longer mis-flagged as the --% stop-parsing token

• Fixed Agent SDK hang when the model emits a malformed tool name in a parallel tool call batch
