# Claude Code 2.1.283

By Steven Van · 2026-09-25

Claude Code 2.1.283 adds gateway hint headers, model allow/deny controls for admins, and a CLAUDE.md prompt audit command.

- Requests can now carry an **x-claude-code-prompt-id** header so LLM gateways can group all the requests that come from one user prompt; it's opt-in via **CLAUDE\_CODE\_GATEWAY\_HINT\_HEADERS=1**.

- Admins get two new managed settings: **availableModelsMatch** set to "exact" locks an **availableModels** entry to that specific model version, so new releases stay blocked until explicitly listed, and **deniedModels** blocks named models even if **availableModels** would otherwise allow them.

- With **OTEL\_LOG\_TOOL\_CONTENT=1**, the **tool.output** OpenTelemetry span event now also captures MCP tool, WebFetch and WebSearch outputs.

- A new **/doctor prompt-audit** command (also available as **/checkup prompt-audit**) audits CLAUDE.md files, skills, agents and commands for prompting patterns written for older models.

- In fullscreen mode, truncated messages from other sessions can now be clicked to expand.

- When a plugin directory fails to load, the **--plugin-dir** load-failure entry in the stream-json system/init output now names the directory path.

- The Claude apps gateway config adds an opt-in **load\_test\_mode** block: requests are built and signed but not sent upstream, and clients get a canned reply, allowing a deployment to be load tested.
