Unclear What tengu_hazy_boole controls is not shown.

What

Plugins add features to Claude Code, and some of their entries can be served through MCP, a way of offering tools to Claude Code from another program. Claude Code has two new remote switches, both off unless they are turned on remotely:

  • tengu_deep_acorn: when on, Claude Code checks a plugin entry again with a stricter pass, and records when an entry would be served alongside plugin hooks that were not loaded.
  • tengu_hazy_boole: read by Claude Code, but what it controls is not shown.

The flag server returned both as off for this site's account and for an anonymous account.

Why

These are quiet safeguards around plugin hooks served over MCP, being prepared before they are switched on.

tengu_deep_acorn 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.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
