Claude Code v2.1.234 ·

Global config file watching can move onto the storage backend

Your global config can be watched through the storage backend instead of the file, falling back if it fails.

What

Claude Code watches ~/.claude.json so changes made by another running process are picked up. A new path subscribes to that config through the storage backend instead and stops watching the file once the subscription succeeds; if it fails, the existing file watcher stays in place.

Details
  • The config state now also records which backend supplies freshness and holds a one-shot claim for resubscribing.
  • Requires both the storage v5 pin (tengu_hover_rest, falling back to false) and a constructed backend, and this build cannot construct one, so the file watcher is what actually runs.
Evidence

Watching ~/.claude.json for other processes through the storage interface

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

tengu_hover_rest Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Added since A small documentation edit on Use Claude Code features in the SDK touched a line naming ~/.claude.json after this was published. When you omit `settingSources`, `query()` reads the same filesystem settings as the Claude Code CLI: user, project, and local settings, CLAUDE.md files, and `.claude/` skills, agents, and commands. To run without these, pass `settingSource… agent-sdk/claude-code-features see the edit
Confirmed since Anthropic's documentation has since written up ~/.claude.json, on CLI reference. | `claude project purge [path]` | Delete all local Claude Code state for a project: transcripts, task lists, debug logs, file-edit history, prompt history lines, and the project's entry in `~/.claude.json`.

What has happened since
Flag reading moved The flag server now returns off for tengu_hover_rest, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
Flag reading moved The flag server now returns nothing at all, having stopped carrying it for tengu_hover_rest, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
