Linear will happily let an issue reach Done with no estimate, no label
and no owner — and then your cycle metrics quietly lie to you.
LineGuard adds the rule layer Linear doesn't have. Pick a trigger
(enters Done, leaves Triage), add conditions, and it reverts the change
with a comment explaining what's missing. Nine one-click presets, so the first rule takes about a minute.
Pricing is flat per workspace — never per seat, so the bill doesn't grow when you hire. Free tier, no card.
