A startup tip pointing at /design for UI work

Not switched on
Useful3 Signal5
Slash Commands Notable not in their notes

A startup tip pointing at a /design command for mocking up UI is present but nobody sees it.

A tip suggesting /design before building UI needs an allow_design_sync entitlement plus a flag defaulting false, so it is inert.

Feature flag
tengu_cedar_plume 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.

/design
What

A new startup tip with the internal id claude-design-command suggests running the /design command before building UI, reading "Working on UI? Run /design to mock up a few directions before you build". It is present but inert in this build: showing it needs the allow_design_sync account entitlement and then a feature flag whose fallback is false, so no one sees it yet. Alongside it, the tip engine gained two general behaviours that apply to all tips.

Details
  • The tip carries priority 1 and will not reappear for 15 sessions once shown.
  • The second gate is tengu_omelette_fouet, and with its fallback of false nothing in this build turns the tip on; the gate function itself shipped in 2.1.235, and only the tip is new here.
  • Tips that advertise a command are now shown only when that command actually exists in the running build.
  • The tip engine skips any tip recorded in its failed-tips list, so a tip that could not be displayed is not retried.
  • This is a distinct tip from the existing claude-design-contextual, which links to a claude.ai URL and is gated by tengu_cedar_plume.

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