Locker Assignment Manager: Know Who Holds Every Locker and Key

Assign lockers to staff, track who holds which locker and key or combo, and reclaim lockers when people leave — with an admin approving every assignment and confirming every handback.

What you'll build

A web tool where staff request a locker, an admin approves each assignment, the holder and key/combo are recorded, offboarding automatically triggers a reclaim task, the admin confirms the handback, and the locker flips back to Available — with a full history and a CSV export of the register.

Before you start

  • A Supabase account (free)
  • A Vercel account (free)
  • A Resend account (free)
  • A CSV or sheet of your lockers (location, size, key/combo) and a CSV of your staff
  • Claude Code or any AI coding agent

The problem this kills

Somewhere in your building there's a wall of lockers, and nobody can say for sure who holds half of them. A few are clearly in use. Several are a mystery — the person who had them left months ago, the key is gone, and the only way back in is bolt cutters. New hires ask for a locker and you guess at which ones are free. When someone leaves, nobody remembers to get the key back, so the locker stays "assigned" to a ghost forever.

It's a small problem that quietly wastes real money and space: lockers sit empty-but-locked, keys disappear, locks get cut, and you buy more lockers you didn't actually need. The fix isn't a fancy access-control system. It's a simple, trustworthy register — one that always shows who holds which locker and key, makes assignment a deliberate decision, and forces a reclaim when someone walks out the door. You do not need to be a developer to build that.

What you'll build

A simple internal web tool for whoever runs your lockers — facilities, the office manager, gym or locker-room staff, plant HR. You load your lockers (location, size, key or combo) and your staff list from a sheet or CSV. A staff member (or you, on their behalf) requests a locker; the admin approves it, and only then is the locker marked Assigned with the holder and the key or combo recorded against it. When someone is offboarded, the tool automatically raises a reclaim task so the locker can't quietly stay ghost-assigned — and the admin confirms the handback (key returned, locker cleared) before it flips back to Available. Every locker keeps a full history of who held it and when, and you can export the whole register as a CSV any time.

What's inside the Implementation Plan

The downloadable plan is a step-by-step file you paste into an AI coding agent. It opens by interviewing you about your business — how lockers are assigned today, where your locker and staff lists live, the exact way your lockers are numbered and labelled, whether you use keys, combos, or both, your peak times (the start-of-season or new-hire rush), and your real rules for who approves an assignment and how offboarding reaches you. It reads a short spec back to you for a thumbs-up, then builds the tool around your answers instead of a generic template. From there it walks the agent through the data model, importing your lockers and staff, the request-and-approve flow, recording the key or combo, the offboarding-triggered reclaim, the confirm-handback gate, the per-locker history, and the CSV export. Every step ends with a ready-to-copy prompt.

The governance it includes (this is the point)

This isn't a toy. The plan builds in the controls a real facilities function needs: login so only your team can use it, row-level security so each site or organization only sees its own lockers, a complete audit trail of every assignment, approval, reclaim, and key change (who, what, when), a hard human-approval gate so a locker never flips to Assigned or Available until a person confirms it, and duplicate guards so a locker can never have two active holders at once. The whole tool exists to make a careful human decision easy and on-the-record — the system drafts the change, a person approves it.

Who it's for

Facilities and office managers, gym and locker-room operators, and plant HR or admin staff who own a wall (or several walls) of lockers and are tired of mystery locks and missing keys. If you can describe how a locker gets handed out and handed back in your world, you can build this.

You've got this — open the plan, paste the first prompt, and you'll have a real locker register running this afternoon.
