Claude Code 2.1.314 adds write-tool boundaries and enterprise routing
Anthropic published Claude Code 2.1.314 on October 30, adding file-tool restrictions and enterprise routing controls. The distinction for developers is scope: a rule for named editing tools is not a whole-process sandbox. Official release notes.
What changed in Claude Code 2.1.314
| Area | Announced behavior |
|---|---|
| File tools | permissions.blockWritesOutsideWorkingDirectories rejects paths outside working directories for Write, Edit and NotebookEdit in every permission mode. |
| Gateway routing | Upstream groups limits routing to listed identity-provider groups, including failover. |
| Bedrock diagnostics | guardrail_trace logs the triggered filter without matching text. |
| Long conversations | VS Code and Desktop Code summarize idle conversations of 200K-plus tokens; the next turn uses the summary if prompt caching expired. |
| Noninteractive runs | Startup failures in claude -p now return an error and exit status 1, not silent status 0. |
A file-tool boundary is not a process sandbox
Anthropic’s sandbox documentation describes a separate operating-system boundary for shell commands and their child processes. Filesystem and network isolation are distinct layers. Permissions decide whether an operation may start; sandbox restrictions constrain the running process.
Consider two operations: changing a configuration through a file-editing tool, and running a build that writes files. They are not the same mechanism. The release notes name the tools covered by the new rule. That description does not establish containment of every subprocess, network request or installed extension. This is a documentation-based scope distinction, not a tested bypass.
What administrators still need to establish
At our October 30 check, the official settings reference had no entry for the new write-boundary key. We are therefore not presenting a deployment recipe or asserting its default or precedence behavior.
The separate settings guide distinguishes personal, shared-project, local-project and managed configuration. It also warns that the published JSON schema can lag newer releases. That warning does not independently resolve the missing details for this particular key.
- Identify the operation. Which action needs a boundary: an editing tool, a shell command or a network request?
- Identify the policy owner. Separate a developer’s project preferences from requirements administered for an organization.
- Separate announcement from validation. A feature appearing in release notes is not evidence that a particular deployment configuration has been tested.
The enterprise context
Version 2.1.312, published October 27, added a gateway option for choosing an identity-token claim and fixed managed-policy retrieval after VS Code sign-in. Together, these releases show attention to identity, policy and operational behavior, rather than only the coding conversation itself.
For readers evaluating the changes, the useful question is not simply whether a new control exists. It is which operation it governs, where its configuration applies and what evidence supports that interpretation. ByteForward has not installed or execution-tested this release.
