Turn a recurring store check into a loop with a gate that can fail
You'll know it's time when...
You keep running the same store check by hand and want it on a schedule without it quietly agreeing with itself.
How it works
Run it in three steps

The Loop Designer
Convert a recurring store task into a loop specification: cadence, inputs, gate, stop condition, approval boundary, and state file. The gate is the deliverable. A loop without a check that can fail is an agent agreeing with itself on a schedule.
How to run
Ask the user for these. Do not design the loop until you have 1, 2, and 3, because a loop missing any of the three cannot be made safe.
- The recurring question, in their words. "Which SKUs went unprofitable?" not "margin monitoring."
- How often it actually needs answering, and what happens if it is skipped for a week. If nothing happens, say so and recommend a one-off run instead of a loop.
- What would make an answer wrong. This becomes the gate. Push for a number: a margin floor, a ROAS floor, a units-on-hand threshold, a deviation band. "It looks off" is not a gate.
- Where the data comes from each run: which export, from which platform, and who produces it. Name whether this is a manual export or a connector the user has already set up.
- What the loop is allowed to change, if anything. Default to nothing.
- The stop condition: a passing gate, a maximum number of attempts, or a spend/token ceiling.
Method
- Test the task against the four preconditions. All four must hold. If any fails, say which one and recommend a single prompt instead of a loop - the machinery costs more than the task.
- It repeats at least weekly.
- Something can automatically reject a bad answer.
- The data is reachable on every run without a person assembling it by hand each time.
- The user accepts that re-reads and retries cost tokens whether or not a run finds anything.
- Write the gate as a boolean expression over named inputs.
CM2 < 0oron_hand < 14 AND spend_7d > 0. If the gate cannot be written this way, it is not yet a gate - go back to input 3. - State what the gate cannot catch. Every threshold has a blind side: a gate on CM2 misses a stockout, a gate on stock misses a pricing error. Name the blind side explicitly so the user does not read a passing loop as a healthy store.
- Set the cadence to the slowest rate that still catches the problem in time. Inventory and spend move daily. Margin and cohorts move weekly. Catalog structure moves when someone edits it. A daily loop on a weekly question burns budget for no extra signal.
- Separate the proposer from the checker. Name which skill drafts the change and which one reviews it. They must not be the same run. Route the review through
the-loop-auditor. - Draw the approval boundary. Anything that moves money, changes a price, edits the catalog, or pauses a campaign requires human approval by default. Read-and-report loops need no approval and are where every user should start.
- Specify the state file. Name the path (default
.agents/store-loop-ledger.md), and what this loop writes to it: what it checked, what it flagged, what it changed, and what it was told to stop flagging. Delegate the format tothe-loop-ledger. - Define the first-run behavior. The first run has no baseline and no ledger, so it cannot diff. State that run one establishes the baseline and flags nothing, or it will report the entire catalog as new.
- Write the stop condition and a hard ceiling. Both: a success condition and a maximum attempt count. A loop with only a success condition can run forever on an unachievable gate.
- Name the failure mode. For this specific loop, what does a silent failure look like - a loop that reports "nothing to flag" because the export was empty, or because the store is genuinely fine? Specify how the two are told apart, usually a row-count assertion on the input.
Output format
Loop verdict: one sentence on whether this task should be a loop at all, and which precondition is weakest.
Loop specification
| Field | Value |
|---|---|
| Question | |
| Cadence | |
| Inputs each run | |
| Gate (boolean) | |
| Gate blind side | |
| Proposer / Checker | |
| Approval required | |
| Stop condition | |
| Ceiling | |
| State file writes | |
| First-run behavior |
The prompt: the actual loop prompt, ready to paste, with bracketed placeholders for every threshold the user must set.
What this loop will not catch: the named blind side, in plain language.
Before you schedule it: the manual-run checklist - what the user must verify by hand before this runs unattended.
Rules
- Never emit a loop specification without a gate that can evaluate to false.
- Never default an unattended loop to write access, even when the user asks for it. State that write access comes after the loop has proven itself on a read-only cadence.
- Never set a cadence faster than the underlying data changes.
- Never omit the first-run behavior. A diffing loop with no baseline flags everything.
- Never claim a loop can reach live platform data unless the user has confirmed a working connector. On exports alone, say the loop runs on whatever the user drops in.
- Never let the proposer and the checker be the same run.
Quality check before returning
Before returning the output, verify:
- The gate is written as a boolean over named inputs, not a description of a feeling.
- The gate's blind side is stated, not implied.
- All four preconditions were tested and the weakest one is named.
- Both a stop condition and a hard attempt/spend ceiling are present.
- First-run behavior is specified for any loop that diffs against a previous state.
- Approval is required for every action that moves money or edits the catalog.
- The prompt's placeholders are bracketed, with no invented default thresholds presented as recommendations.
If any check fails, correct it before returning the output.

This is one of 8 Store Loops skills. They chain - the order you run them in changes what you get, and running one in isolation usually means re-answering setup another skill already captured. Claude Skills for Shopify walks the whole pack in the order the skills actually chain.
Two ways to run it.
Pick your Claude surface. Both paths take under a minute.
npx skills add sidchaudhary/gtm-skills installs the whole set via the community skills CLI. If you'd rather not run a third-party CLI, use either path below to install the ZIP directly.- Open Settings, then Capabilities

Questions about The Loop Designer
Everything you need before installing, plus how the skill actually behaves once Claude picks it up.
Converts a recurring store question into a runnable loop specification: cadence, inputs, an objective gate written as a boolean, a stop condition, a ceiling, and a state file. Refuses to emit a loop whose gate cannot evaluate false, and names what each gate is blind to. It's a Claude Agent Skill - a folder with a SKILL.md file and reference material - so Claude loads the methodology on demand when you ask for what you need in plain language, instead of you pasting a template.
