The drill has been out for three weeks. The rule on the card says seven days. Two stewards think weekends do not count. A third thinks the card is a suggestion. The next person who needs the drill is standing in a garage looking at an empty hook.
A tool library is a small commons. The rules only work if the people who loan and the people who borrow can point at the same sentence. A comment thread on the street chat is where that sentence goes to die.
Write both rules, then ask
"I need A or B by Thursday on the loan period: keep seven calendar days, or move to fourteen with one written renewal." Current rule in a sentence. Proposed rule in a sentence. Closed list.
That is a decision. "How should we handle overdue tools?" is a topic. Topics produce twelve designs and no card on the hook.
Give the facts that break the default: three tools are out past a month, the weekend-count argument has already happened twice, the insurance note names fourteen days as the cap you already told the insurer. Cut the story of who borrowed the tile saw in June.
State your lean. "I recommend fourteen with one renewal. I keep seven if two stewards say the shed cannot track renewals." The second sentence is what would change your mind.
Name the shape. If the stewards vote, it is a decision. If you are the only signer on the shed lease and you want a sanity check, it is an opinion — say that, or people will think they own a call they do not.
Ask the people who vote, not the block
A rule change that goes to forty households is a referendum you may not have agreed to run. If five stewards decide, write to those five. One address at a time. After they answer, post the recorded rule where borrowers already look.
A steward may have no account. That is fine. The briefing is email and a page. They reply from either. You approve the wording first.
If they already use RelayLink, invite them and wait for the accept. The request carries no note. The rule briefing comes after they say yes.
Do not put your private nickname for a neighbor in the package. They have a name on the street.
What a sufficient answer is
One line. "B." "A — we cannot track renewals." Say that a short reply is enough. Then a default: "If I do not hear by Thursday evening, we keep seven days and I reprint the card."
No handbook file. Write the two sentences. If the handbook lives in a shared folder, name the folder.
If two stewards use different assistants, nothing is shared except the briefing. That is enough.
What this is not
It is not a place to process a person who keeps tools. A rule is a rule. A conversation with one borrower is a different message, with their name on it, and often better as a call if you already know it will sting.
It is not a vote on whether the library should exist. If that is the real question, say so, and do not hide it under a loan period.
If your assistant already has the card text, let it draft both sentences. You read them. Then the stewards can answer.
