DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Skill suggestion card, off by default

Skills

A card suggesting standalone skills only fires when you ask, unless a server flag flips.

tengu_saddle_lantern falls back to off, keeping the conservative prompt.

Feature flag
tengu_saddle_lantern Gate removed from the code

This release deleted the gate from the code while it was still reading on for the account this site reads, so the code path no longer asks a flag before running.

Read once, for one account on one subscription tier, against v2.1.248. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A tool that renders a card of standalone skills you can add is present but not enabled. With the gate tengu_saddle_lantern off, which is the built-in fallback, it only fires when you explicitly ask for recommendations; with it on, a longer prompt applies and Claude offers skills proactively without being asked. Nothing in this build sets the flag, so whether it is on is decided by server config.

Details
  • The same gate is what the whole skills and plugins tool family checks, covering search, list, and install-suggestion tools.
  • The gate is bypassed entirely when CLAUDE_CODE_REMOTE is set.
  • The flag itself is not new; what is new is that this whole tool set now hangs off it.
Evidence

tengu_saddle_lantern

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