Source Intelligence

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.

Agent Teams Enabled by Default (with env var)

Feature flag
tengu_amber_flint 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.

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.

Read once, for one account on one subscription tier, against v2.1.33. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The tengu_amber_flint feature flag now defaults to true, enabling agent teams for users who set CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.

Details
  • Previously, the feature flag defaulted to false, requiring both the env var AND server-side enablement
  • Now users only need to set CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 to use agent teams
  • The system prompt note about agent teams "not available on this plan" is now conditionally hidden when teams are enabled
Evidence

Feature flag change from !1 (false) to !0 (true) (search for "tengu_amber_flint")

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