Order rules and see what they did

Know how rules run in order and chain, read a rule's recent runs and fix one that cannot run.

In short

Rules run top to bottom, and a change one rule makes can set off others. Each rule keeps its recent runs - applied, skipped or could not run, and why - so you can see what it did and fix one that stopped working.

Before you start

Who: changing the order and editing rules needs "Create and manage boards". Anyone who can open the board reads recent runs.
Plan: every plan.
First: make at least one rule (see /help/boards/board-rules).

Steps

Open Board settings › "Automation". "Custom rules" opens its list.
Choose "Run earlier" or "Run later" on a rule.

In the list, read how often each rule applied and how its last run went.
Open "Recent runs" to see the last 30 times it met a card.
Edit a rule marked as broken - its column, card type or person is gone.

In the rule's "..." menu, choose "Try it on the cards". You need "Create and manage boards".
Read what it would do to each card: "Would change", "Would skip" or "Could not run", with the reason, and what each action would do.
A rule on the clock, a column or a field is tried on the cards that meet its condition now. Any other rule is tried on the latest changed open cards, as if it set off for each.
Nothing changes on the board. Save a new rule switched off, try it, then switch it on.

Result: the rules run in the order you set, and you can see why one did or did not act.

Good to know

A rule sees what the rules above it changed.
A rule that moves a card sets off the rules for the column it lands in. A chain stops after three steps, and a rule never runs twice on the same card in one chain.
Recent runs reads "Applied". It may read "Could not run", with the reason, such as a column no longer on the board. Or it may read "Skipped", when the card already looked the way the rule asks or a chain had gone on long enough.

If something goes wrong

It did not run: it is switched off, the card is not of the type or priority it is for, or the change happened on another board.
Could not run: the column or the person it names is no longer on this board. Edit the rule.
Skipped after a repeat: two rules undo each other. Change one.
Skipped after three steps: let one rule do more instead.
