What it does

Shopify Admin Inventory Adjustment is an agent skill from 40RTY-ai/shopify-admin-skills. Apply inventory quantity adjustments to specific variants at specific locations — after a cycle count, 3PL return batch, or sync discrepancy correction.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Claude Code, Cursor, Codex, Gemini CLI

It works with Shopify. The repository describes itself as: Community-maintained AI agent skills for operating Shopify stores — workflows, optimization, reports and more. The licence is MIT.

Example prompts

  • “/shopify-admin-inventory-adjustment”

Requirements

  • Compatibility (from SKILL.md): Claude Code, Cursor, Codex, Gemini CLI

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. OPERATION: productVariants — query
  2. OPERATION: inventoryAdjustQuantities — mutation

What it can do on your machine

Read from SKILL.md and the folder at commit 6765cb4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • shopify

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Claude Code, Cursor, Codex, Gemini CLI

    From compatibility in the SKILL.md frontmatter.

Context cost

Shopify Admin Inventory Adjustment loads about 1.7k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 528 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Purpose

Applies inventory quantity corrections to specific variants at specific locations — the programmatic equivalent of manually editing inventory in the Shopify admin. Use after a cycle count reveals discrepancies, after a 3PL return batch posts late, or after the multi-location-inventory-audit skill identifies Available/Committed drift. Replaces manual row-by-row inventory editing in the Shopify admin.

Prerequisites

  • shopify auth login --store <domain>
  • API scopes: read_products, write_inventory

Parameters

ParameterTypeRequiredDefaultDescription
storestringyes—Store domain (e.g., mystore.myshopify.com)
formatstringnohumanOutput format: human or json
dry_runboolnofalsePreview operations without executing mutations
adjustmentsarrayyes—Array of {sku, location_id, delta} objects. delta is the signed quantity change (e.g., +5 to add 5 units, -3 to remove 3)
reasonstringnocorrectionAdjustment reason logged to audit trail: correction, cycle_count, damaged, received, reservation_created, reservation_deleted, shrinkage
reference_document_uristringno—URI to link the adjustment to a PO, return, or cycle count document

Safety

⚠️ Step 2 executes inventoryAdjustQuantities which immediately changes live inventory quantities. Incorrect adjustments can cause overselling (if you reduce too far) or inflated stock counts (if you add incorrectly). Run with dry_run: true to see the before/after quantities per SKU before committing. The reason field is logged permanently in Shopify's inventory activity history.

Workflow Steps

  1. OPERATION: productVariants — query Inputs: For each {sku} in adjustments: look up the variant by SKU to get its inventoryItem.id; also fetch current inventoryQuantity for before/after comparison Expected output: Map of {sku → inventoryItemId, currentQuantity} for all adjustment targets; abort if any SKU is not found

  2. OPERATION: inventoryAdjustQuantities — mutation Inputs: changes array of {inventoryItemId, locationId, delta, ledgerDocumentUri} using the reason and reference_document_uri parameters Expected output: inventoryAdjustmentGroup.changes with quantityAfterChange per item; userErrors

Session Tracking

Claude MUST emit the following output at each stage. This is mandatory.

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: inventory-adjustment                 ║
║  Store: <store domain>                       ║
║  Started: <YYYY-MM-DD HH:MM UTC>             ║
╚══════════════════════════════════════════════╝

After each step, emit:

[N/TOTAL] <QUERY|MUTATION>  <OperationName>
          → Params: <brief summary of key inputs>
          → Result: <count or outcome, e.g., "143 records returned">

If dry_run: true, prefix every mutation step with [DRY RUN] and do not execute it.

On completion, emit:

For format: human (default):

OUTCOME SUMMARY
  SKUs adjusted:        <value>
  Total units added:    <value>
  Total units removed:  <value>
  Errors:               <count, 0 if none>
  Output:               <filename or "none">
══════════════════════════════════════════════

For format: json, emit a JSON object with this schema:

Output Format

CSV file inventory-adjustments-<YYYY-MM-DD>.csv with columns: sku, product_title, location_name, quantity_before, delta, quantity_after, reason.

Error Handling

ErrorCauseRecovery
SKU not foundSKU doesn't exist in storeVerify SKU spelling; use low-inventory-restock to browse valid SKUs
inventoryItem.tracked: falseVariant has inventory tracking disabledEnable tracking in Shopify admin before adjusting
userErrors from mutationInvalid delta, invalid location, or permission issueCheck write_inventory scope and verify location GID
Delta would push quantity below 0Adjustment removes more than availableConfirm correct delta value; use negative delta only for known stock removals

Best Practices

  1. Always run dry_run: true first — the before/after CSV preview lets you confirm every change before it hits live inventory.
  2. Use reason: cycle_count with a reference_document_uri pointing to your count sheet — this creates a permanent audit trail in Shopify's inventory activity log.
  3. Batch all corrections from a single count session into one command rather than applying one-at-a-time — the audit trail groups them under a single inventoryAdjustmentGroup.
  4. After adjusting, run multi-location-inventory-audit again to confirm all discrepancies are resolved.
  5. For 3PL return batches, use reason: received and link the return batch document URI — this makes reconciliation with your 3PL invoice straightforward.
