Feature flags are communication

A flag is a promise to two audiences at once: users see a coherent product, teammates see incomplete work safely. Mess up either and the flag becomes a liability.

Key takeaways

— A flag promises users a coherent product and teammates the truth.
— Every flag gets a birthday and a removal date.
— One flag, one behaviour; default-off means tested-off.

The two audiences

Users get the flag's facade: a complete experience either way. Teammates get the flag's truth: the work is partial, the default is off, the removal date exists. The beta-opt-in pattern in the prompt catalog renders both — the enrol toggle for users, the cohort note for the team.

Flags have birthdays and funerals

Every flag gets a creation date and an intended removal. The flag list that shows 'created 14 months ago, still defaulting off' is the most valuable dashboard nobody builds — and the reason stale flags outnumber live features in most codebases.

One flag, one behaviour. A flag with three states is three flags.
Default-off means default-tested-off, too.
The removal ticket is filed when the flag is born.
