Version 2.1.131

Claude Code 2.1.131 is a small maintenance release with no new CLI commands, flags, settings, or visible tips detected in the diff from 2.1.129. The user-facing changes are concentrated in API plumbing: bundled file operations now target stable Files API paths, and API-client authentication errors now describe the supported auth inputs more directly.

Stable Files API Paths #

What

Bundled Anthropic file operations now call the stable /v1/files endpoints instead of beta-suffixed file URLs.

Usage
claude
Details
  • This affects internal/API-backed file list, upload, download, metadata, and delete calls.
  • Existing Claude Code workflows should not need new flags or settings.
  • The old implementation used /v1/files?beta=true and /v1/files/{id}/content?beta=true; the new implementation uses /v1/files and /v1/files/{id}/content.
Evidence

Files API client paths changed from beta URLs to stable URLs (search for "/v1/files" and "/v1/files?beta=true").

Clearer API Authentication Error #

What

When the bundled Anthropic API client cannot resolve credentials, the error now says it expects either apiKey or authToken, instead of listing removed credential/profile/config options.

Usage
ANTHROPIC_API_KEY=... claude
Details
  • This makes auth failures less misleading for users who hit lower-level API-client errors.
  • The new message points users toward API key or bearer-token authentication.
  • The previous message referenced credentials, config, and profile; those are no longer listed in the failure text.
Evidence

Authentication validation message changed (search for "Could not resolve authentication method. Expected either apiKey or authToken to be set").

Bundled Beta SDK Surface Cleanup #

Several bundled beta Anthropic SDK resources were removed from the CLI package, including generated client bindings for managed agents, sessions, environments, vaults, memory stores, and user profiles. This appears to be cleanup of packaged SDK internals rather than a new Claude Code CLI workflow: no corresponding new slash command, flag, setting, or tip was added in this release.

Evidence

Removed beta client routes include "/v1/agents?beta=true", "/v1/sessions?beta=true", "/v1/vaults?beta=true", "/v1/memory_stores?beta=true", and "/v1/user_profiles?beta=true".
