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.

Feature flag
tengu_agent_list_attach 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.

This account: off · anonymous baseline: off · compiled default in v2.1.178: not a boolean we can read

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 v2.1.178. It isn't a statement about your account. What a flag value here can and cannot tell you

  • Bash prompt rule denials are now classified as safetyCheck type (rather than other) with classifierApprovable: false, ensuring auto-mode cannot override safety denials. (search for "Denied by Bash prompt rule")
  • Precomputed compact is now correctly gated: it can activate for non-user-query sources that have a precomputed swap available, fixing cases where compaction would not trigger when it should. (search for "precomputed compact: arm gated")
  • WIF (Workload Identity Federation) token refresh now checks sibling-process-rotated tokens before performing a new refresh grant, avoiding redundant token rotations in multi-process scenarios. (search for "wif: adopting sibling-rotated access token from credentials file")
  • Agent list attachment is no longer gated by tengu_agent_list_attach — the check that previously required the feature flag is removed, making agent context more consistently available. (search for "tengu_agent_list_attach" absent from new code)
  • Design OAuth credential error messages are improved: the expand_failed case now includes guidance to run /design-login as an alternative, rather than only suggesting /login. (search for "Could not add design scopes to the token", "or run /design-login to authorize design access separately")
