検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Added `sandbox.allowNestedUserNamespaces` so sandboxed commands on Linux can create user namespaces (Chromium, rootless podman); this lets them get around the sandbox's file protections - Added `CLAUDE_CODE_RETRY_WATCHDOG_USAGE_LIMIT_RECHECK_MS` so unattended retry mode (`CLAUDE_CODE_RETRY_WATCHDOG`) notices a usage limit that was lifted before its reset - Fixed every request f

検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Added `CLAUDE_CODE_DISABLE_FILE_MENTIONS` environment variable: Claude gets the paths of `@` file mentions to read with its file tools, not the files' contents - Added idle compaction in the terminal: a 200K+ token conversation left idle for about 54 minutes is compacted before its one-hour prompt cache expires, so your next message doesn't reprocess it all - Added `CLAUDE_CODE
検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Added a `code` key to the Claude apps gateway's `managed.policies[]`: the same settings as `cli`, also applied in Claude Desktop's Code tab; beside `desktop`, it turns on Claude Desktop's gateway mode - Added `autoCompactWindow` to subagent frontmatter and `--agents` definitions, so a subagent can auto-compact earlier than the main conversation's window - Added `CLAUDE_CODE_WOR

検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Fixed `prompt` and `agent` hooks written as instructions (such as "Block commands that...") allowing what they should block - Improved how `prompt` hooks on Stop and SubagentStop written as instructions (such as "Carry on if the build is broken") are judged, so Claude is less likely to stop early
検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Added Claude Haiku 5.5 (`claude-haiku-5-5`), now the default Haiku model on the Anthropic API — 1M context, $0.10/$0.50 per Mtok ($0.50/$2.50 for prompts over 100K) - Added `agentType` to the `subagentStatusLine` payload, so scripts can tell custom subagent types apart - Added `isDeferred` to `$.tool.register` for mods: `false` lists the tool's schema in the prompt from the sta

検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Added `serverToolUses` to the result of a mod's `turn.step` hook: the tool calls the API ran itself (the advisor), each with its id, name, input, start and end - Added `agentId` to the `tool.check` event of plugin hooks, so a hook can tell a subagent's permission check from the main session's - Added `ceiling` to the question and verdict a mod's `tool.check` hook reads, naming

検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Changed auto mode for Claude API and Enterprise users, and on Bedrock, Vertex, Foundry and gateways, to default to the server-side classifier, which does not charge for classifier overhead (`CLAUDE_CODE_AUTO_MODE_SERVER=0` opts out on Bedrock, Vertex, Foundry and gateways); warns on billed fallback. See https://code.claude.com/docs/en/auto-mode-classifier-billing - Added an `Au
検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Added AGENTS.md support: in a project with no CLAUDE.md, Claude Code reads AGENTS.md instead; change it under "Project instructions" in `/config` (not yet on Bedrock, Vertex or Foundry) - Added `CLAUDE_GATEWAY_PROXY_IS_EGRESS_BOUNDARY=1` for Claude apps gateways whose only egress is a forward proxy: every outbound request hands the proxy the hostname instead of resolving it loc
検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Fixed every request failing with `400 … Input tag 'advisor_20260301'` when `ANTHROPIC_BASE_URL` points at a proxy or gateway (2.1.275 regression)

検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Added `maxEffortLevel` setting (top-level or per model under `modelSettings`): caps the effort level on every provider, including Bedrock, Vertex and Foundry; users can still pick a lower level - Added `--system-prompt-snapshot off` to render the system prompt fresh on every request instead of reusing the conversation's recorded prompt (for iterating on prompt text) - Fixed Cow
検証済みの公式情報の抜粋 · 英語anthropic / Claude Code ## What's changed - Fixed a 2.1.265 regression affecting LLM-gateway and proxy setups: the undocumented `CLAUDE_CODE_USE_GATEWAY` environment variable, previously ignored unless `ANTHROPIC_BASE_URL` and `ANTHROPIC_AUTH_TOKEN` were both set, began forcing Cloud-gateway sign-in on its own in 2.1.265, so configurations that set it alongside an API key, `apiKeyHelper`, or custom auth headers failed ev
