Claude Code v2.1.234 ·

Startup prefetch failures no longer surface

A bad skill or command directory no longer produces a startup error; workflows are pre-warmed too.

What

The startup prefetch now calls a dedicated cache warmer instead of building the full command list. Skill and command loads run together and every failure is swallowed, so a bad skill or command directory no longer produces a startup error. The warmer also pre-loads workflows.

Details
  • The loads run under a settle-all wrapper inside a try/catch, and the skills load time is still recorded as a startup phase.
  • Workflow warming short-circuits when workflows are off: the enableWorkflows setting set to false, the CLAUDE_CODE_WORKFLOWS environment variable set to false, or the tengu_workflows_enabled gate (fallback true) off.

Feature flag
tengu_workflows_enabled On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

Read once, for one account on one subscription tier, against v2.1.234. It isn't a statement about your account. What a flag value here can and cannot tell you

What has happened since
Flag reading moved The flag server now returns on for tengu_workflows_enabled, 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.
